The amount of aspirin, A, present in the bloodstream x hours after taking a 325 mg pill is represented by the

function A = A,b* where A, and b are constants. After 3 hours, there is about 199. 6 mg of aspirin remaining in

a patient's bloodstream. What is the value of b, and what does it mean in the context of the problem?

Answers

Answer 1

The amount of aspirin in the bloodstream will be about 0.838 times what it was before.

The function that represents the amount of aspirin, A, present in the bloodstream x hours after taking a 325 mg pill is:

[tex]A = A_0 \times b^x[/tex]

where A_0 is the initial amount of aspirin in the bloodstream (which is 325 mg), and b is a constant that represents the rate of decay of the aspirin in the bloodstream.

We are told that after 3 hours, there is about 199.6 mg of aspirin remaining in the patient's bloodstream. Using the function above, we can set up an equation based on this information:

[tex]199.6 = 325 \times b^3[/tex]

To solve for b, we can divide both sides by 325 and then take the cube root of both sides:

[tex]b^3[/tex]= 199.6 / 325

b = [tex](199.6 / 325)^{(1/3)[/tex]

b ≈ 0.838

So the value of b is approximately 0.838. In the context of the problem, this means that the amount of aspirin in the bloodstream decreases by a factor of approximately 0.838 every hour. In other words, if we wait one hour,  If we wait two hours, it will be about (0.838)^2 times what it was before, and so on. This exponential decay model can be useful in predicting how long it will take for the aspirin to be completely eliminated from the bloodstream.

The ratiοs are nοt equal fοr all the squares, which means there is nοt a prοpοrtiοnal relatiοnship between diagοnal length and area.

Using the fοrmula fοr finding the area οf a square, we have:

Area οf square A = side length squared

Area οf square A = 4.8 x 4.8

Area οf square A = 23.04 square cm

Similarly, we can find the areas οf squares B, C, and D:

Area οf square B = 5.2 x 5.2 = 27.04 square cm

Area οf square C = 6.4 x 6.4 = 40.96 square cm

Area οf square D = 3.6 x 3.6 = 12.96 square cm

Nοw, let's find the lengths οf the diagοnals οf each square using the Pythagοrean theοrem:

Diagοnal οf square A = √(4.8² + 4.8²) = 6.77 cm

Diagοnal οf square B = √(5.2² + 5.2²) = 7.35 cm

Diagοnal οf square C = √(6.4² + 6.4²) = 9.06 cm

Diagοnal οf square D = √(3.6² + 3.6²) = 5.09 cm

Tο determine if there is a prοpοrtiοnal relatiοnship between the length οf the diagοnals and the areas οf the squares, we need tο cοmpare the ratiοs οf the diagοnals tο the areas fοr each square.

Fοr example, the ratiο οf diagοnal length tο area fοr square A is:

Ratiο οf diagοnal length tο area fοr square A = diagοnal length / area

Ratiο οf diagοnal length tο area fοr square A = 6.77 cm / 23.04 square cm

Ratiο οf diagοnal length tο area fοr square A = 0.294

We can repeat this fοr the οther squares and cοmpare the ratiοs. If the ratiοs are apprοximately equal fοr all the squares, then there is a prοpοrtiοnal relatiοnship between diagοnal length and area.

Ratiο οf diagοnal length tο area fοr square B = 0.272

Ratiο οf diagοnal length tο area fοr square C = 0.221

Ratiο οf diagοnal length tο area fοr square D = 0.393

As we can see, the ratiοs are nοt equal fοr all the squares, which means there is nοt a prοpοrtiοnal relatiοnship between diagοnal length and area.

valor aproximado de 25 m2 de cerámica de azulejos es de C$3 125 en una ferretería local. Cuál será la cantidad (m2) de azulejos que se puede comprar con un presupuesto
de C$ 15 625?

Answers

According to the question we can say that with a budget of T$15,625, you can purchase approximately 5.5 square meters of ceramic tiles at the given price of C$3,125 for 25 m2.

What is division?

Among the four fundamental arithmetic operations, or ways to mix numbers to create new ones, is division. Multiplication, addition, as well as subtraction make up the remaining operations.

To find the quantity of tiles that can be purchased with a budget of T$15,625, we need to calculate the cost per square meter of the tiles and then divide the budget by this cost.

The cost per square meter of the tiles is given by:

C$3,125 / 25 m2 = C$125/m2

To convert C$125/m2 to T$, we need to use the current exchange rate. Let's assume that the current exchange rate is 1 CAD = 0.75 USD and 1 USD = T$30.

C$125/m2 * 0.75 USD/CAD * 30 T/USD = T$2,812.50/m2

Now we can calculate the quantity of tiles that can be purchased with a budget of T$15,625:

Quantity of tiles = Budget / Cost per square meter

Quantity of tiles = T$15,625 / T$2,812.50/m2

Quantity of tiles = 5.5 m2 (rounded to the nearest 0.5 m2)

Therefore, with a budget of T$15,625, you can purchase approximately 5.5 square meters of ceramic tiles at the given price of C$3,125 for 25 m2.

Answers

Answer: Sorry, I cannot provide visual aids or diagrams. However, I can help with the mathematical calculations and solutions to the given problems.

(a) To construct a trapezium WXYZ, follow the steps below:

Draw a straight line segment WX of length 10.2 cm and draw a line segment YZ of length 5.8 cm parallel to WX, such that the distance between them is 8.3 cm.

Draw a line segment XY of length 5.6 cm perpendicular to both WX and YZ, joining their endpoints.

From the endpoint Z, draw a perpendicular line segment ZN to WX.

Angle LWXY is given as 60°, so mark a point L on WX, such that angle WLY is 60°.

Therefore, the trapezium WXYZ is constructed.

(b) From the diagram, we can see that ZN is perpendicular to WX, so triangles ZWX and ZYN are similar.

Using the similar triangles ZWX and ZYN, we can write:

WX/WY = ZN/XY

10.2/5.6 = ZN/5.8

ZN = (10.2/5.6) * 5.8

ZN ≈ 10.57 cm

(c) Using Pythagoras' theorem, we can find the length of WZ:

WZ² = WX² - XZ²

WZ² = 10.2² - 8.3²

WZ ≈ 4.3 cm

Therefore, |WZ| ≈ 4.3 cm and |ZN| ≈ 10.57 cm.

(a) Let the width of the frame be w and the length be l. Then, according to the problem,

cost ∝ w * √l

cost = k * w * √l, where k is the constant of proportionality.

Using the given information, we can find the value of k as follows:

N115 = k * 10 * √25

k = N115 / 50

k = N2.3

Therefore, the law of variation is cost = N2.3 * w * √l.

(b) For a frame of width 12 cm and length 49 cm,

cost = N2.3 * 12 * √49

cost = N2.3 * 12 * 7

cost = N193.2

(a) Since the range R = {2, 5, 10}, we know that f(x) can take only these three values. Therefore,

x² + 1 = 2 or x² + 1 = 5 or x² + 1 = 10

Solving each of these equations for x, we get:

x = ±√1 or x = ±√4 or x = ±√9

x = ±1 or x = ±2 or x = ±3

Therefore, the domain D = {-3, -2, -1, 1, 2, 3}.

To find f-¹(5), we need to find the values of x for which f(x) = 5. From the equation x² + 1 = 5, we get:

x² = 4

x = ±2

Therefore, f-¹(5) = {-2, 2}.

Find the work done by the force field F on a particle moving along the given path.
F(x, y) = x^2i − xyj
C: x = cos^3(t), y = sin^3(t) from (1, 0) to (0, 1)

Answers

The answer of the given question based on the finding the work done by the force, is  field F on a particle moving along the path C is 1/6.

What is Force?

A force is defined as influence that causes object to undergo change in motion. It is vector quantity, means it has both magnitude and direction.

To find the work done by the force field F on a particle moving along the given path, we need to evaluate the line integral of F along the path C.

The line integral of a vector field F along a curve C parameterized by r(t) is given by:

∫ F(r(t)) ⋅ r'(t) dt

where r'(t) is the derivative of r(t) with respect to t.

In this case, the force field F(x, y) = x²i − xyj, and the path C is given by x = cos³(t), y = sin³(t) from (1, 0) to (0, 1).

First, we need to parameterize the path C in terms of t. Since x = cos³(t) and y = sin³(t), we can express the path C as a vector function r(t) = ⟨cos³(t), sin³(t)⟩, where t goes from 0 to π/2.

we need to find derivative of r(t) with the respect of  t:

r'(t) = ⟨-3cos³(t)sin(t), 3sin²(t)cos(t)⟩

Now, we can evaluate the line integral of F along C:∫ F(r(t)) ⋅ r'(t) dt

= ∫ (cos⁶(t)i - cos³(t)sin⁴(t)j) ⋅ (-3cos²(t)sin(t)i + 3sin²(t)cos(t)j) dt

= ∫ (-3cos⁸(t)sin(t) + 3cos³(t)sin⁵(t)) dt

= [-3/9cos⁹(t) - 3/6cos⁴(t)cos²(t)]_0^(π/2)

= 0 - (-3/9 - 3/12)

= 1/6

Therefore, the work done by the force field F on a particle moving along the path C is 1/6.

Answers

The cost of each of the items are calculated as:

Cost of pass = $14

Cost of souvenir = $10.5

Cost of burger = $1.75

How to solve Algebra Word Problems?

Let us define the parameters first:

p = cost of pass

³/₄p = cost of souvenir (which is three quarters of the cost of the pass)

¹/₈p = cost of burger (multiply ³/₄p by ¹/₆)

all costs are in dollars

Adding p, ³/₄p, and ¹/₈p leads to

p + ³/₄p + ¹/₈p

(8p/8) + (6p/8) + (p)/8

(8p + 6p + p)/8

15p/8

This expression represents the total Sammy spent.

We know he started with $28.25 and has $2.00 left over, so he spent 28.25 - 2.00 = 26.25 dollars. Set this equal to 15p/8 and solve for p to get:

15p/8 = 26.25 dollars

15p = 8 * 26.25

15p = 210

p = 210/15

p = $14

³/₄p = cost of souvenir = ³/₄ * 14 = $10.5

¹/₈p = cost of burger = ¹/₈ * 14 = $1.75

what is a polynomial?

Algebraic expressions called polynomials include coefficients and variables. Indeterminates are another name for variables. For polynomial expressions, we can do mathematical operations like addition, subtraction, multiplication, and positive integer exponents but not division by variables. [tex]$x^2+x-12$[/tex] is an illustration of a polynomial with a single variable.

from the question:

The degree and leading coefficient of the polynomial [tex]$-2 x^4-3 x^2-x+5$[/tex]must be examined in order to determine its final behavior.

As the polynomial has a degree of 4 , it will expand or decay at a pace dictated by the leading coefficient as x gets closer to positive or negative infinity. The negative (leading) coefficient is -2 .

As in this instance, the final behavior of a polynomial with a negative leading coefficient and an even degree is as follows:

- The polynomial will decrement without bound as x approaches positive infinity, causing the y values to decrement steadily. This is due to the fact that as x increases significantly, the term with the highest degree takes over the polynomial, and since the leading coefficient is negative, the polynomial reduces.

- The polynomial will grow without bound as x gets closer to negative infinity, which causes the y-values to get steadily increasingly positive. This is because as x gets very tiny and negative, the term with the highest degree dominates the polynomial, and since the leading coefficient is negative, the polynomial rises.

Hence, the polynomial [tex]$-2 x^4-3 x^2-x+5$[/tex] has the following final behavior:

- The polynomial decreases without bound as x get closer to positive infinity.

- The polynomial grows without bound as x gets closer to negative infinity.

Assume that adults have IQ scores that are normally distributed with a mean of 100. 3 and a standard deviation of 17. 6. Find the probability that a randomly selected adult has an IQ greater than 132. 7. ( Round to four decimals please )


Assume that adults have IQ scores that are normally distributed with a mean of 101. 8 and a standard deviation of 15. 7. Find the first Q1 , which is separating the bottom 25%from the top 75%. ( type an integer or decimal rounded to one decimal place as needed )

Answers

The probability that an arbitrarily chosen adult has an IQ higher than 132.7 is 0.0322, or roughly 3.22%.

Using a standard normal distribution table, we can find the z-score corresponding to an IQ of 132.7:

z = (132.7 - 100.3) / 17.6 = 1.84

The probability of a randomly selected adult having an IQ greater than 132.7 is equal to the area to the right of the z-score of 1.84 on the standard normal distribution curve:

P(Z > 1.84) = 0.0322 (rounded to four decimals)

Therefore, the probability of a randomly selected adult having an IQ greater than 132.7 is 0.0322 or about 3.22%.

The Value of first quartile Q1 is 91.2.

For the second part, we need to find the IQ score that separates the bottom 25% from the top 75%. Using a standard normal distribution table, we can find the z-score corresponding to the 25th percentile:

z = invNorm(0.25) = -0.6745

Now we can solve for the IQ score using the formula:

z = (x - μ) / σ

-0.6745 = (x - 101.8) / 15.7

x - 101.8 = -10.603

x = 91.197

Rounded to one decimal place, the first quartile Q1 is 91.2.

The z-score of a measure X of a variable that has mean symbolized by [tex]\mu[/tex] and standard deviation symbolized by [tex]\sigma[/tex] is obtained by the rule presented as follows:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

The z-score represents how many standard deviations the measure X is above or below the mean of the distribution, depending if the obtained z-score is positive or negative.Using the z-score table, the p-value associated with the calculated z-score is found, and it represents the percentile of the measure X in the distribution.

The mean and the standard deviation for this problem are given as follows:

[tex]\mu = 65, \sigma = 7[/tex]

The probability that there will be at least 81 cartoons is one subtracted by the p-value of Z when X = 81, hence:

Z = (81 - 65)/7

Z = 2.29

Z = 2.29 has a p-value of 0.989.

(we can consider this for any Saturday as outcomes of the normal distribution are independent).

Hence the probability is obtained as follows:

1 - 0.989 = 0.011 = 1.1%.

A. $0.61
B. $0.55
C. $0.54
D. $0.62
Pls help!!! i need this done tonight​

Answers

Answer:

The cost of the chocolate bar is $0.54. You can calculate this by subtracting the total cost of the peanut butter bars ($3.50) from the total cost of the 5 peanut butter bars and 6 chocolate bars ($6.40), resulting in $2.90 for the cost of the chocolate bars, which is then divided by 6 to get $0.54.

Using the circle below, find each arc length. Round to the nearest hundredth.
ST = ____
RPT = ____

Answers

arcST and arcRPT of the given circle are measured at 55 and 208 degrees, respectively.

What is circle?

Every point in a plane that is at a certain distance from the center point forms a circle. In order to go around a curve while maintaining a constant distance from another point, a moving point in a plane must follow a specific path.

The following expression will be used to determine the length of the arc ST:

arcPS = arcPT + arcST

Already given,

• arcPT = 125 degrees

• arc PS = 180 degrees

Putting the value in equation

arcST = arcPS - arcPT

arcST = 180  - 125

arcST = 55 degrees

Following the same steps we can get

arcPR = 180 - arcRS

arcPR = 180 - 97

arcPR = 83 degrees

and also

arcRPT = arcPR + arcPT

arcRPT = 83 + 125

arcRPT = 208 degrees

Hence the measurement of arcST and arcRPT are 55 and 208 degree respectively.

4. Tshering claims that if she triples the side length of a square (s), the area of the square will also be tripled. Do you agree? Explain your thinking.​

Answers

Tshering's claim is incorrect because the area is not trippled, but it is multiplied by a factor of 9

How to determine if Tshering's claim is correct

Given the the side length is

Side length, s = s

So, the area is

Area = s²

When the side length is trippled, we have

New side length, S = 3s

So, the area is

New area = (3s²)

New area = 9s²

Divide the new area by the initial area

Factor = 9s²/s²

So, we have

Factor = 9

This means that the area is multiplied by 9 and not tripled

if a rectangle the area of 16 square unit, would could the measure of the sides be?

Answers

Answer:

See below.

Step-by-step explanation:

We are asked to find measures of the unknown sides for the given area.

Let's keep in mind that a rectangle's area is; [tex]Area = (width) \times (height)[/tex]

One simple way to find all of the possible side lengths is to find all of the factors of 16.

What are Factors?

Factors are 2 whole numbers that multiply together to have the product of that given number.

Think of how many ways we can get to 16 by multiplying 2 numbers.

[tex]f_{1} \times f_{2} = 16\\f \ represents \ a \ factor.[/tex]

Here's all of the possible ways we can get to 16 with whole numbers.

[tex]8 \times 2 = 16\\4 \times 4 = 16\\2 \times 8 = 16\\1 \times 16 = 16\\16 \times 1 = 16[/tex]

Remember that the Width and Length of a Rectangle can have different values even with the same numbers multiplied.

[tex](8 \times 2) \ and \ (2 \times 8)\\Length \ can \ equal \ 2, \ or \ 8.\\Width \ can \ equal \ 8, \ or \ 2.[/tex]

These are all of the possible answers.

In mathematics, you can multiply, divide, add, or subtract. An expression is formed as follows: Expression, number, and math operator Numbers, parameters, and functions make up a mathematical expression. It is possible to contrast phrases and expressions. Every mathematical statement that comprises variables, numbers, and a mathematical action between them is referred to as an expression. For example, the phrase 4m + 5 is made up of the phrases 4m and 5, as well as the variable m from the provided equation, all separated by the mathematical symbol +.  

We can use the following formula:

distance = time x speed

We know the distance is 315 km and the time is 3 hours for automobile A. As a result, we can compute its speed as follows:

speed = distance / time = 315 kilometres / 3 hours = 105 kilometres per hour

So we know that car B has the same speed as automobile A, which is 105 km/h. Car B takes 2 hours and 30 minutes, which is comparable to 2.5 hours. Hence, we can apply the same procedure to calculate the distance travelled by automobile B:

Distance is speed multiplied by time = 105 km/h multiplied by 2.5 hours = 262.5 kilometres

As a result, at the same pace as automobile A, car B will go 262.5 kilometres in 2 hours and 30 minutes.

One edge of a painting is 6 in. longer than the other edge. The painting has a 2-inch-wide frame. The function f(x) = x2 + 14x + 40 represents the total area of the painting and frame. Find the total area of the painting and the frame if the longer side of the frame is 14 inches long.

A rectangle that has a length of X plus 6 and a width of X, surrounded by a 2 inch frame on all sides.

area: _____in.2

Answers

The total area of the painting and frame is 248 inches squared.

What is area?

Area is the size of a two-dimensional surface, typically defined by its length and width. It is an important concept in mathematics and is used to measure different shapes and figures. Area is also commonly used to measure the size of land, such as a city block or a region of a country. Areas can be measured in square meters, square kilometers, hectares, square feet, and many other units. Knowing the area of a shape or space can be helpful when planning a project or understanding how much space something requires.

Using the given equation, f(x) = x2 + 14x + 40, we can solve for the area of the painting and frame.

f(x) = x2 + 14x + 40
f(x) = (x + 6)2 + 2(x + 6)(2) + 2(2)(2)
f(x) = x2 + 12x + 36 + 4x + 24 + 16
f(x) = x2 + 16x + 56

We are told that the longer side of the frame is 14 inches long, so x = 8.

f(8) = 8^2 + 16(8) + 56
f(8) = 64 + 128 + 56
f(8) = 248 in.2

Therefore, the total area of the painting and frame is 248 inches squared.
