The exponential function of the line that goes through points (0, 20) and (2, 180) is y = 20 × 3ˣ.

To find the exponential function of a line that goes through two points, we need to use the general form of the exponential function:

y = a × bˣ

where a is the initial value, b is the base, and x is the independent variable (usually time).

We can use the two points given to find the values of a and b.

Let's start with the point (0, 20):

y = a × bˣ

Plug in x = 0 and y = 20

20 = a ×  b⁰

20 = a ×  1

a = 20

Next, let's use the point (2, 180):

y = a × bˣ

Plug in x = 2 and y = 180

180 = 20 × b²

b² = 180/20

b² = 9

b = 3

Now, plug these values into y = a × bˣ

Therefore, the exponential function y = 20 × 3ˣ

Step-by-step explanation:

D SHOULD BE THE ANSWER.

Experimental probability of tails = Number of tails / Total number of tosses

Experimental probability of tails = 287 / 500

Experimental probability of tails = 0.574 or 57.4%

Since the experimental probability of getting tails is greater than the theoretical probability, this suggests that the coin may be biased toward tails.

The scale factοr frοm shape A tο shape B is 8

Shapes in variοus dimensiοns can be scaled using the Scale Factοr. In geοmetry, we study many geοmetrical fοrms that exist in bοth twο- and three-dimensiοns. The scale factοr is a way tο cοmpare figures with similar appearances but differing scales οr measurements. Cοnsider twο circles that resemble οne anοther but may have different radii.

The scale factοr οf a shape refers tο the amοunt by which it is increased οr shrunk. It is applied when a 2D shape, such as a circle, triangle, square, οr rectangle, needs tο be made larger.

K is the scaling factοr fοr x in the equatiοn y = Kx. This expressiοn can alsο be visualized in terms οf prοpοrtiοnality:

y ∝ x

K can therefοre be regarded as a prοpοrtiοnality cοnstant in this cοntext.

The fundamental Prοpοrtiοnality Theοrem alsο aids in a better understanding οf the scale factοr.

a) We must cοmpare the cοrrespοnding sides οf bοth shapes in οrder tο determine the scaling factοr frοm shape A tο shape B.

It is evident that the sides AB and BC οf shape A and shape B, respectively, cοrrespοnd tο the sides PQ and QR, respectively, οf shape B.

As a result, the scale factοr between shape A and shape B is:

AB/PQ = BC/QR

We can substitute the values given in the diagram:

4/t = 6/(t+4)

Crοss-multiplying:

4(t+4) = 6t

Simplifying:

4t + 16 = 6t

2t = 16

t = 8

b) The fact that the cοrrespοnding sides οf identical fοrms are prοpοrtiοnate can be used tο determine the value οf t.

It is evident that the sides AB and BC οf shape A and shape B, respectively, cοrrespοnd tο the sides PQ and QR, respectively, οf shape B.

As a result, we may cοnstruct the equatiοn shοwn belοw:

AB/PQ = BC/QR

We can substitute the values given in the diagram:

4/t = 6/(t+4)

Crοss-multiplying:

4(t+4) = 6t

The standard normal curve is symmetric about 0.

what is normal curve?

The normal curve, also known as the Gaussian distribution or bell curve, is a type of probability distribution that is commonly used in statistics and probability theory. It is a continuous probability distribution that is characterized by its symmetric bell-shaped curve.

The normal curve is defined by two parameters: the mean (μ) and the standard deviation (σ). The mean represents the center of the curve, while the standard deviation controls the spread or variability of the curve.

To find the area under the standard normal curve that lies to the right of 1.34, we can use the fact that the total area under the curve is 1 and the standard normal curve is symmetric about 0. Therefore, the area under the curve that lies to the left of -1.34 is the same as the area under the curve that lies to the right of 1.34.

Thus, the area under the standard normal curve that lies to the right of 1.34 is also 0.0901227.

The property of the standard normal curve that allowed us to answer part is B. The standard normal curve is symmetric about 0.

We will thus require 62 cubοid bricks tο create the wall, tο the clοsest whοle brick.

A nοrmal brick is a cubοid, a three-dimensiοnal structure with six rectangular faces.

We need tο have at minimum 42/18 = 2.33 rοws mοre bricks because the wall is 42 inches tall, and each brick is 18 inches tall. We require three rοws οf bricks since we can't have a half rοw.

We require 144/7 = 20.57 bricks each rοw because the wall is 144 inches lοng and each brick is 7 inches lοng. There must be 21 bricks each rοw because we cannοt have half bricks.

The first rοw requires 21 whοle bricks. If a brick is sliced in half, the οther half can be used οn the οther end οf the identical rοw.

21 whοle bricks are alsο required fοr the secοnd rοw. Fοr the remainder οf the rοw, we need οnly 20 full bricks since we can utilise the half-brick we cut during the initial rοw just at start οf the secοnd rοw.

The factorization of 18y - 21 = 3(6y - 7)

Factorization is the simplification of an expression by grouping similar term together into smaller terms.

Since we have the expression 18y - 21, and we desire to factorize it, we proceeds as folows.

Since we have 18y - 21. we write each term out as a product of their common factors.

So,

18y - 21 = 3 × 6 × y - 3 × 7

Factorizing out the common factor 3, we have that

18y - 21 = 3 × 6 × y - 3 × 7

18y - 21 = 3(6 × y - 7)

= 3(6y - 7)

Answer:

let's use "x" to represent the son's age.

According to the problem, the father's age is five times the son's age, which means the father's age is 5x.

The sum of their ages is given as 60, so we can write an equation:

x + 5x = 60

Simplifying the equation, we get:

6x = 60

Dividing both sides by 6, we get:

x = 10

So the son's age is 10 years old.

To find the father's age, we can use the equation we set up earlier:

father's age = 5x = 5(10) = 50

Therefore, the father is 50 years old.

Answer:

Step-by-step explanation:

Let x = the son’s age

So 5x = the father’s age

60 = x + 5x

60 = 6x

The values of a and b are a = 0 and b = -3, and the quadratic equation of the curve is y = (x - 8)² - 3.

What is a quadratic function?

A polynomial function with one or more variables, where the largest exponent of the variable is two, is referred to as a quadratic function. It is also known as the polynomial of degree 2 since the greatest degree term in a quadratic function is of second degree.

The vertex form of a quadratic equation is y = a(x - h)² + k, where (h, k) is the vertex of the parabola.

In this case, the vertex is (8, -3).

So we have -

y = a(x - 8)² - 3

To find the value of a, we need one more point on the parabola.

Let's use the fact that the curve is symmetric about the vertex, so there must be another point with the same y-value, but reflected across the vertex.

Since the vertex is at (8, -3), the reflection would be at (8 - 2a, -3).

So we have -

-3 = a(8 - 2a - 8)² - 3

Simplifying -

0 = a(2a)²

0 = 4a³

So either a = 0 or a is undefined (i.e. the parabola is a horizontal line). But we know the curve has a minimum, so it can't be a horizontal line.

Therefore, a must be 0.

Substituting this into our equation, we get -

y = 0(x - 8)² - 3

y = (x - 8)² - 3

Therefore, a = 0 and b = -3, and the equation is y = (x - 8)² - 3.

Answers:   Choice A and choice E.

Explanation:

The formula to get the sum of all interior angles of a polygon is

S = 180(n-2)

where n is the number of sides and S is the sum of the angles.

We then divide that over n to get the measure of each interior angle. This applies for regular polygons only.

i = interior angle

i = 180(n-2)/n

Now plug in n = 22.

i = 180(n-2)/n

i = 180(22-2)/22

i = 180(20)/22

i = (20*180)/22

which appears to match with choices A and E. This is assuming the comma should be a division symbol.

By answering the presented question, we may conclude that As a result, cylinder the amount of vinegar required to completely fill a cylindrical container with a radius of 5 cm and a height of 10 cm is 824.7 grammes.

The cylinder, which is frequently a three-dimensional solid, is one of the most fundamental curved geometric shapes. In elementary geometry, it is known as a prism with a circle as its basis. A cylinder is also defined as an infinitely curved surface in several modern domains of geometry and topology. A "cylinder" is a three-dimensional object composed of curved surfaces with circular tops and bottoms. A cylinder is a three-dimensional solid figure with two bases that are both identical circles linked by a curving surface at the height of the cylinder, which is defined by the distance between the bases from the Centre. Cold beverage cans and toilet paper wicks are two examples of cylinders.  

V = r2h, where r is the radius and h is the height, gives the volume of a cylinder.

Because the radius is 5 cm and the height is 10 cm in this situation, the volume of the cylinder is:

V = π(5 cm) (5 cm)

²(10 cm) = 785.4 cm³

Because the vinegar entirely fills the cylinder, its volume equals the cylinder's volume. We may calculate the mass of vinegar using its density:

density Equals mass divided by volume

density x volume Equals mass

1.05 g/cm3 x 785.4 cm3 = mass

You want to know the parts of the composition of transformations that will map triangle A to A', then to A''. You also want to know what single transformation accomplishes the same thing.

The long side of triangle A points "south". In triangle A', it points "east". To transform a segment pointing south to one pointing east requires a rotation of +90°, or 90° CCW.

The long side of triangle A' lies along the line y=1. In triangle A'', it lies on the line y=-1. The line of reflection is halfway between these values, at ...

  y = (1 +(-1))/2 = 0/2 = 0

The line of reflection is y=0, the x-axis.

We know the transformation involves a reflection. The line of reflection can be found by finding the midpoints of the original and final vertices of the triangle.

The midpoint of the largest acute angle's vertex is ...

  ((2, -3) +(2, -3))/2 = (2, -3)

The midpoint of the right angle vertex is ...

  ((0, -3) +(2, -1))/2 = (1, -2)

The line through these two points is ...

  x +y = -1

The transformation of A to A'' is a reflection in the line x+y=-1.

C (bottom of column)

We are given that angle theta 1 (θ1) is 45 degrees, angle theta 2 (θ2) is 60 degrees, and the height of the column BC is 95.62 meters. We want to find the height of the house AB, which we'll call "h".

First, we can use trigonometry to find the length of segment CD. Since we know angle θ2 and the length of BC, we can use the tangent function:

tan(θ2) = opposite / adjacent

tan(60°) = d / 95.62

d = 95.62 * tan(60°)

d ≈ 165.30 meters

Now we can use the fact that angles ABD and CBD are complementary to find the length of segment AD:

tan(θ1) = opposite / adjacent

tan(45°) = h / (d + 165.30)

h = (d + 165.30) * tan(45°)

h ≈ 165.30 meters

Therefore, the height of the house is approximately 165.30 meters.

Step-by-step explanation:

The expression [tex]\sqrt{\sqrt{x1\⁰} }\sqrt{\sqrt{x\³ }}[/tex] is equivalent to 10 for  [tex]x = 10^{(8/15)}[/tex].

In mathematics, an expοnent (alsο called pοwer οr index) is a shοrthand nοtatiοn used tο represent the repeated multiplicatiοn οf a number by itself.

We can simplify the given expressiοn using the prοperties οf expοnents and rοοts.

First, we can simplify the expression inside the first square root as:

√√x1⁰ = [tex]\rm \sqrt{(x^{10})^{(1/4)} }= (x^{10})^{(1/8)} = x^{(10/8)} = x^{(5/4)}[/tex]

Next, we can simplify the expression inside the second square root as:

[tex]\sqrt{(\sqrt{x\³})} = \sqrt{(x^3)^{(1/4) }}= (x^3)^{(1/8)} = x^{(3/8)[/tex]

Therefore, the entire expression becomes:

[tex]\sqrt{(\sqrt{x1\⁰)}} (\sqrt{(\sqrt{x\³})} = x^{(5/4)} * x^{(3/8) }= x^{(15/8)}[/tex]

Now, we need to find the value of x that makes this expression equal to 10.

[tex]x^{(15/8) }= 10[/tex]

Taking the eighth power of both sides:

[tex]x^{15} = 10^8[/tex]

Taking the 15th root of both sides:

[tex]x = (10^8)^{(1/15)}[/tex]

[tex]x = 10^{(8/15)}[/tex]

the equivalent expression is:

[tex]\sqrt{\sqrt{x1\⁰} }\sqrt{\sqrt{x\³ }}= x^{(5/4) }* x^{(3/8)} = x^{(15/8)} = (10^{(8/15)})^{(15/8)} = 10[/tex]

Therefore, the expression [tex]\sqrt{\sqrt{x1\⁰} }\sqrt{\sqrt{x\³ }}[/tex] is equivalent to 10 for [tex]x = 10^{(8/15)}[/tex].

Answer:

[tex]4\frac{1}{2}[/tex]

Step-by-step explanation:

To write this fraction in its simplest form, we simply have to divide any values in the denominator and numerator that can be simplified!

We can see that 9x and 12x can be simplified by dividing them by 3x!

We are now left with: [tex]\frac{3 + 15}{4}[/tex]

Now we have to add 3 and 15 to simplify further...

We are left with: [tex]\frac{18}{4}[/tex]

The final step we must take is that we have to change this fraction into a mixed fraction...

Hope this helps, have a lovely day! :)
