Kate is firing off her homemade rockets for a project in physics class. The
maximum height of any of her rockets can be represented by the equation
h-701-162, where h is the height (in feet) of the rocket after t seconds.

Answers

Answer 1

The domain and range for the function for the maximum height of the rockets Kate fires is; h = 70·t - 16·t² are;

Domain; 0 ≤ t ≤ 4.375

Range; 0 ≤ h ≤ 39.06

What is a mathematical function?

A function is a rule that defines the relationship between input variables and output variables, such that the each value from the set of input variables are assigned to exactly on variable from the set of output variables.

The possible specified function in the question is; h = 70·t - 16·t², and the possible required details is the domain and range that best represent the situation.

The domain of the above function is the set of possible input (t) values, which is found by the time it takes the rocket to land after flight as follows;

At ground level, h = 0, therefore;

h = 70·t - 16·t² = 0

(70 - 16·t)·t = 0

A possible solution is therefore, t = 0

The other solution is found as follows;

(70 - 16·t) = 0

70 = 16·t

16·t = 70

t = 70/16 = 4.375

The other solution or time at which the rocket is at ground level is t = 4.375

The domain is therefore; 0 ≤ t ≤ 4.375

The range is the set of possible h values, which is obtained as follows;

The maximum point of the quadratic function, f(x) = a·x² + b·x + c, is the point, x = -b/2·a. Therefore, comparison between the function, f(x) = a·x² + b·x + c, and h = 70·t - 16·t², we get;

a = -16

b = 70

c = 0

The maximum height reached, therefore is obtained at the point, at which; t = -70/(2 × (-16)) = 2.1875

The maximum height, [tex]h_{max}[/tex], is therefore;

[tex]h_{max}[/tex] = 70 × 2.1875 - 16 × 2.1875² =  76.5625

The range is therefore; 0 ≤ h ≤ 76.5625

How would paying off the lowest outstanding balance credit card first be beneficial over paying off the one with the highest?

Answers

Paying off the lowest outstanding balance credit card first will not be beneficial over paying off the one with the highest. Instead, it's beneficial to pay the highest outstanding balance first.

Actually, paying the one with the highest interest rate is logically the right thing to do because you can shorten the amount that you spend on interest or charges by month, but paying the lowest outstanding balance credit card first makes more sense if you could transfer the highest interest balance into a low or maybe no interest rate that is being offered to another card, only if you are so certain that you will pay the remaining balance or on before its due. 

It should be remarked that paying off the lowest outstanding balance credit card first cannot be beneficial over paying off the one with the highest interest rate.

It's significant to pay the one that has the highest interest rate. This is because it'll assist in shortening the amount the person will pay as interest.

In conclusion, it's important to pay the highest Interest rate.

Drag and drop the answer into the box.

Answers

The length of DH (diagonal) in the rectangular prism is approximately 3.5 inches.

How to Find the Measure of the Diagonal of a Right Rectangular Prism?

A rectangular prism has three dimensions: length, width, and height. The diagonal of a rectangular prism is the distance between two opposite corners of the prism.

To find the diagonal of a rectangular prism, you can use the Pythagorean theorem, which states that the square of the diagonal is equal to the sum of the squares of the length, width, and height.

In this case, the length is 1.5 inches, the width is 1 inch, and the height is 3 inches. So, you can use the formula:

d² = 1.5² + 1² + 3²

d² = 2.25 + 1 + 9

d² = 12.25

Then take the square root of the d²

d = √12.25

d ≈ 3.5 inches.

Therefore, the measure of the diagonal of the rectangular prism is approximately 3.49 inches.

After traveling 70 meters in its dive, the submarine is at a depth of 25 meters. About what will the submarine’s depth be if it continues its dive for another 110 meters? Round to the nearest whole number A) 40m

B) 64m

C) 18m

D) 4m

Answers

About 40 meters the submarine’s depth be if it continues its dive for another 110 meters. So the option A is correct.

Since it is essentially a ratio problem, we can use the information given and apply the Rule of Three assuming that the submarine is moving at a constant speed.

In this rule, the depth after 110 meters is obtained by simply multiplying the ratio's diagonal values and dividing by the last value.

70min = 25 m

110min = x m

x = (110 × 25)/70

x = 2750/70

x = 39.28

x = 40(approx)

We can see that at 110 minutes, the depth would have been approximately 40 meters, but since the submarine travelled further during this time, we must add this measurement to the original 25 meters to determine the submarine's total depth.

Answers

the total FBT liability for this benefit is $329 ($700 x 47% = $329).

Fringe Benefits Tax (FBT) is imposed by the Australian Taxation Office (ATO) on certain non-cash benefits provided to employees. If a company provides a weekend stay in Sydney valued at $1,000 as a Christmas gift in December 2022, the FBT liability is calculated as follows:

The taxable value of the benefit is calculated by deducting the expenses that are not subject to FBT, i.e. $300 (flight) from the total value of the gift, i.e. $1,000. This leaves a taxable value of $700 ($1,000 - $300 = $700).

The FBT liability is then calculated by multiplying the taxable value, i.e. $700, by the FBT rate which is currently 47% (as of 2021). This results in an FBT liability of $329.

Therefore, the total FBT liability for this benefit is $329 ($700 x 47% = $329).

Answers

Answer:2.75 (or 11/4, they are equal).

Step-by-step explanation: The graph of f(x) is continuous on the closed interval and differentiable on the open interval. Now we need to find the average slope over the interval, which is [0-3]/[5-(-4)] = -3/9 = -1/3. The goal is to find a place where f'(c) = -1/3, so basically anywhere where the derivative equals -1/3. First we need to find the derivative of the function which can be rewritten as (5-x)^(1/2). Differentiating this using the chain rule gives you -1/(2*sqrt(5-x)). Set this equal to -1/3. The numerator is -1, so really we just need to find where the denominator, 2sqrt(5-x), is equal to 3. Divide by 2 and get sqrt(5-x) = 3/2. Square both sides and get 5-x = 9/4. Subtract 5 and get -x = -2.75, so x = 2.75. This means c = 2.75.

Maria is 5 feet 3 inches tall. Marla is 4 feet 11 inches tall, Mandy is 5 feet 2 inches tall
and Marilyn is 4 feet 8 inches tall.. What is the average height of these 4 friends? Explain
how you found your answer.

Answers

Answer:

the average height is 5 feet 0 inches

Step-by-step explanation:

To find the average height of Maria, Marla, Mandy and Marilyn, we need to add up their individual heights and divide by the number of people in the group.

First, we need to convert all the heights to a common unit of measurement. Since inches are the smallest unit of measurement, we will convert all the heights to inches.

Maria: 5 feet 3 inches = 63 inches

Marla: 4 feet 11 inches = 59 inches

Mandy: 5 feet 2 inches = 62 inches

Marilyn: 4 feet 8 inches = 56 inches

Now we can add up the heights:

63 inches + 59 inches + 62 inches + 56 inches = 240 inches

To find the average, we divide the total height by the number of people:

240 inches / 4 people = 60 inches

So the average height of these four friends is 60 inches or 5 feet, which is the same as 5 feet 0 inches.

Therefore, the average height of these four friends is 5 feet 0 inches.

The volume of the solid is approximately 32π/3 cubic units.

The volume of the solid obtained by rotating the region bounded by the curves y = 4 - 1/2x, y = 0, x = 0, and x = 1 about the x-axis can be found using the method of disks/washers. The formula for the volume is given by:

V = π * ∫[a,b] (R^2 - r^2) dx

where R is the outer radius (4 - 1/2x), r is the inner radius (y = 0), a and b are the limits of x (x = 0 and x = 1), and dx represents a small slice of the solid.

Evaluating the definite integral:

V = π * ∫[0,1] (16 - x^2 - x^2) dx = π * ∫[0,1] (16 - 2x^2) dx = π * (16x - 4/3 x^3) evaluated at x = 1 - x = 0 = π * (16 - 4/3) = 32π/3 cubic units.

Answers

If Steven made $4,800 this month, the value of his sales for the month is $51,000.

How the sales value is determined:

Steven's base monthly salary on sales of $17,000 = $2,700

First sales commission above $17,000 sales = 10%

Second bonus commission above $25,000 sales = 5%

Total earnings for the month = $4,800

Commissions:

First sales commission = $800 ($25,000 - $17,000 x 10%)

Additional bonus commission = $1,300 ($4,800 - $2,700 - $800)

$1,300 = 5%

Sales above $25,000 = $26,000 ($1,300/5%)

Sales value = $51,000 ($25,000 + $26,000)

What is the value of f(m) = 55?

Answers

Answer:

Step-by-step explanation:The exponent of a number shows how many times the number is multiplied by itself.

According to the rules of exponents,

We know that, am ÷ an = am − n

(5m ÷ 5−3) = 55

5m−(−3) = 55

5m + 3 = 55

The bases are the same on both the sides, so their exponents must be equal.

∴ m + 3 = 5

⇒ m = 5 − 3

⇒ m = 2

Work shown for problem 1

[tex](f - g)(\text{x}) = f(\text{x}) - g(\text{x})\\\\(f - g)(\text{x}) = (2\text{x}^2+\text{x}-3)-(\text{x}-1)\\\\(f - g)(\text{x}) = 2\text{x}^2+\text{x}-3-\text{x}+1 \\\\(f - g)(\text{x}) = 2\text{x}^2-2\\\\[/tex]

This leads to choice D as the final answer.

The domain is the set of all real numbers since the result is a polynomial. Any polynomial function has the domain "all real numbers". This is because we don't have anything like a division by zero error. We also don't have to worry about square roots of negative values.

Work shown for problem 2

[tex](f * g)(\text{x}) = f(\text{x}) * g(\text{x})\\\\(f * g)(\text{x}) = (2\text{x}^2+\text{x}-3) * (\text{x}-1)\\\\(f * g)(\text{x}) = \text{x}(2\text{x}^2+\text{x}-3)-1(2\text{x}^2+\text{x}-3)\\\\(f * g)(\text{x}) = 2\text{x}^3+\text{x}^2-3\text{x}-2\text{x}^2-\text{x}+3\\\\(f * g)(\text{x}) = 2\text{x}^3-\text{x}^2-4\text{x}+3\\\\[/tex]

This leads to choice A as the final answer.

The domain is the set of all real numbers for the exact same reasoning as problem 1.

suppose you have a column of experimental data in column j and a column of positions for each experimental point in column k. what formula would you put in cell location h10 to find the numerical derivative at position 10 of column k of the data found in j? write your answer in your word document.

Answers

The formula would you put in cell location h10 to find the numerical derivative at position 10 of column k of the data found in j is =DERIVXY(h10, k10, j)

The term called derivative is defined as the process to determine the rate of change of a quantity with respect to another changing quantity

Here we have to write the formula for the cell location h10 to find the numerical derivative at position 10 of column k of the data found in j.

As from the definition, the general form derivative function is written as,

=> =DERIVXY(x, y, p, [options])

where x a vector of the points x-coordinates and y corresponding vector of the points y-values and p the point at which to compute the derivative.

Here we have the values of x as h10, y as k10 and p as j

Then the formula is written as,

=> =DERIVXY(h10, k10, j)

Mia estimated 5/8 + 1/9 by replacing 5/8 with 1 and 1/9 with 0. Her

estimated sum was 1 + 0 = 1. Explain why Mia's estimate is Not accurate?

NOT accurate.

Answers

Estimation done by Mia is not accurate, as the accurate estimated sum of the given expression 5/8 + 1/9  is equal to ( 1/2).

Estimation done by Mia is not accurate:

Replaced 5 /8 with 1.

But accuracy represents:

0 < (1 /4 ) < ( 1 /2 ) < (5 /8 ) < ( 3 / 4 ) < 1

( 5 / 8 ) is more close to ( 1 /2 ).

Estimated value of ( 5 / 8 ) is ( 1 / 2 )

0 < ( 1 / 9 ) < ( 1 / 4 )

So , estimated value of ( 1 / 9 ) is 0

Estimated sum = ( 1 / 2 ) + 0

                         = ( 1 / 2 )

                         ≠ 1

Therefore, accurate estimated sum of 5/8 + 1/9  is equal to ( 1 /2 ).

Which descriptions and equations could be the function rule? Select all that apply.
The table in the attached image shows some of the input and output values for a function rule.

Answers

For the given table of values the equation that could be the function rule is option 4: y = 3x - 2.

What is a function?

In mathematics, a function is a unique arrangement of the inputs (also referred to as the domain) and their outputs (sometimes referred to as the codomain), where each input has exactly one output and the output can be linked to its input.

The table of input and output values are given for the function.

The slope-intercept form of an equation/function is - y = mx + b

To find the slope m use the formula -

(y2 - y1)/(x2 - x1)

Substituting the values in the equation -

[-2 - (-11)]/[0 - (-3)]

(-2 + 11)/(0 + 3)

9/3

3

So, the slope point is obtained as m = 3.

The equation becomes - y =3x + b

To find the value of b substitute the values of x and y in the equation -

-11 = 3(-3) + b

-11 = -9 + b

b = -11 + 9

b = -2

So, the value for b is -2.

Now, the equation becomes -

y = 3x - 2

The graph is plotted for the function.

Therefore, the equation is y = y = 3x - 2.

100 millimeters. What is the area of the plate?

Answers

The area of the plate of the microscope with a circumference of

100mm is 2500/π mm².

What is the area of the circle?

A circle is simply a closed 2-dimensional curved shape with no corners or edges.

The area of a circle is expressed mathematically as;

A = πr²

The circumference of a circle is expressed as 2πr.

Given the data in the question;

Circumference of the plate C = 100 mmRadius r = ?Area A = ?

First, we determine the radius of the plate.

Circumference C = 2πr

100 = 2πr

r = 100/2π

r = 50/π

Now, calculate the area of the plate.

A = πr²

A = π ( 50/π )²

A = π × 2500/π²

A = 2500π / π²

A = 2500/π mm²

Therefore, the area of the plate is 2500/π mm².
