Vertical translations would affect the horizontal asymptote.

the total cost of a $76.01 item is $81.14 .

Step-by-step explanation:

Here we have ,  sales tax is six 3/4% . We need to find that what is the total cost of a $76.01 item .Let's find out:

Sales tax is actually the extra money we need to give apart from actual cost of item which is given to government or concerned authority .

Tax is 6(3/4)% of cost price i.e.

[tex]Tax = \frac{cost-price(6\frac{3}{4})}{100}[/tex]

⇒ [tex]Tax = \frac{cost-price(6\frac{3}{4})}{100}[/tex]

⇒ [tex]Tax = \frac{(76.01)(6.75)}{100}[/tex]

⇒ [tex]Tax = \frac{513.06}{100}[/tex]

⇒ [tex]Tax = 5.13[/tex]

So, total cost = $76.01 + $5.13

total cost = $81.14

Therefore, the total cost of a $76.01 item is $81.14 .

Without knowing the type of triangle or the values of the angles, we can only provide a possible range of values for side AC of triangle ABC, which is between 9 inches (in case of an acute triangle) and 47 inches (in case of an obtuse or right angled triangle). For accurate calculation, more detail is necessary.

The question pertains to determining the length of the side AC in a triangle ABC. Given are the lengths AB and BC so without additional details such as the angle values or the nature of the triangle, we cannot definitively determine the length of side AC. Such a calculation usually requires the use of trigonometric calculations or the Pythagorean theorem which applies only to right triangles. However, we can establish a range for the possible length of side AC.

If the triangle ABC is obtuse or a right triangle with the right angle at point B, the length of AC (AB+BC) could be up to 47 inches (19 inches + 28 inches). On the other hand, if it is an acute triangle, the length of AC (BC-AB) would be a minimum of 9 inches (28 inches - 19 inches). Please provide more details or check if it's a right triangle for a more specific calculation.

Answer: B) 42 + x = 90

Step-by-step explanation:

A complementary angle always equals 90 degrees. So, with that information, all you have to do is list the measurement of b as x and create an equation. Knowing that the measurement of angle a is 42 degrees, we can now find an equation. So, we would take the measurement of angle a, 42 degrees, and add the measurement of angle b, listed as x, which should equal 90 degrees.

Answer:

48 yards

Step-by-step explanation:

we know that

The circumference of a circle is equal to

[tex]C=2\pi r[/tex]

we have

[tex]r=7.6\ yd\\\pi=3.14[/tex]

substitute

[tex]C=2(3.14)(7.6)=48\ yd[/tex]

Answer: 48 yards

Step-by-step explanation:

The circumference of a circle can be calculated with the following formula:

[tex]C=2\pi r[/tex]

Where "C" is the circumference of the circle and "r" is the radius of the circle.

In this case you know that the radius of the circular track is the following:

[tex]r=7.6\ yd[/tex]

Knowing tha radius, you can substitute it into the formula (According to the information given in the exercise, you need to use [tex]\pi =3.14[/tex])

[tex]C=2(3.14)(7.6\ yd)[/tex]

Finally, you need to evaluate.

Therefore, you get that the whole yards of fencing that they need to purchase to enclose the track is:

[tex]C\approx48\ yd[/tex]

Answer: OPTION A.

Step-by-step explanation:

A dilation is defined as a transformation in which the Image (The figure obtained after the transformation) and the Pre-Image (The original figure before the transformation) have the same shape, but they have different sizes.

In this case you know that the dilation is centered at the origin and the scale factor is:

[tex]k=0.5[/tex]

Therefore, the rule is the following:

[tex]Q(kx,ky)[/tex]

You can identify in the figure attached that the point Q is:

[tex]Q(1,5)[/tex]

Therefore, you must multiply its coordinates by the scale factor 0.5 in order to get its Image Q'. This is:

[tex]Q'=(1*0.5,5*0.5)\\\\Q'=(0.5.2.5)[/tex]

Final answer:

The image of point Q for a dilation with a scale factor of 0.5 and center (0,0) is (option A) (0.5, 2.5).

Explanation:

To find the image of point Q, we need to apply the dilation equation: (x', y') = (k * x, k * y), where (x, y) are the coordinates of the original point and k is the scale factor.

In this case, the center of dilation is (0, 0) and the scale factor is 0.5. So, for point Q which has coordinates (x, y), the image coordinates (x', y') will be:

(x', y') = (0.5 * x, 0.5 * y)

Therefore, the image of point Q will be (option A) (0.5, 2.5).

Answer:

X = 4

Step-by-step explanation:

Solve for x.

-3x + 4 = -8

Make sure to subtract both sides.

-3x (+4 -4) = -8 - 4

-3x= -12

Divide by -3 on both sides.

-3x/-3 = -12/-3

Answer:

4

Step-by-step explanation:

-3x + 4 = -8

Subtract 4 from both sides

-3x + 4 - 4 = -8 - 4

-3x = -12

Divide both sides by by -3

x = -12/-3

x = 4

Answer: 150 miles

Step-by-step explanation:

The distance between Chicago and Indianapolis is approximately 150 miles.

To find the distance between Chicago and Indianapolis using their latitude and longitude coordinates, we can apply the Pythagorean theorem. The distance between two points on the Earth's surface can be approximated by considering the Earth as a flat plane, which is reasonable for relatively short distances like the one between these two cities.

The difference in latitude (north-south distance) between Chicago and Indianapolis is:

[tex]\[ 42N - 40N = 2N \][/tex]

The difference in longitude (east-west distance) between the two cities is  [tex]\[ 86W - 88W = 2W \][/tex]

Since each degree is approximately 53 miles, we can calculate the north-south distance and the east-west distance:

North-south distance in miles:

[tex]\[ 2N \times 53 \text{ miles/degree} = 106 \text{ miles} \][/tex]

East-west distance in miles:

[tex]\[ 2W \times 53 \text{ miles/degree} = 106 \text{ miles} \][/tex]

Now, we can use the Pythagorean theorem to find the straight-line distance (the hypotenuse of the right triangle formed by the north-south and east-west distances):

Let [tex]\( d \)[/tex] be the distance between the two cities, then:

[tex]\[ d^2 = (106 \text{ miles})^2 + (106 \text{ miles})^2 \] \\[/tex]

[tex]\[ d^2 = 11236 \text{ miles}^2 + 11236 \text{ miles}^2 \] \\[/tex]

[tex]\[ d^2 = 22472 \text{ miles}^2 \] \\[/tex]

[tex]\[ d = \sqrt{22472 \text{ miles}^2} \] \\[/tex]

[tex]\[ d \approx 150 \text{ miles} \][/tex]

The missing length x is 99 m.

Solution:

Given polygons are similar.

If two triangles are similar, then the corresponding sides are in proportion.

[tex]$\Rightarrow\frac{81}{18}=\frac{x}{22}[/tex]

Multiply by 22 on both sides, we get

[tex]$\Rightarrow\frac{81}{18}\times 22=\frac{x}{22}\times 22[/tex]

[tex]$\Rightarrow\frac{9}{2}\times 22=x[/tex]

⇒ 9 × 11 = x

⇒ 99 = x

Switch the sides.

⇒ x = 99

The missing length x is 99 m.

Answer:

Kevin needs 96 points on his last test to raise his mean test score to 90 points.

Step-by-step explanation:

we know that

The mean score is the total of all scores divided by the total number of tests.

Let

x_1 ----> the score in the first math test

x_2 ----> the score in the second math test

x_3 ----> the score in the third math test

x_4 ----> the score in the fourth math test

we have

After taking the first 3 tests, his mean test score is 88 points

so

[tex]\frac{x_1+x_2+x_3}{3} =88[/tex]

[tex]x_1+x_2+x_3=264[/tex] ----> equation A

How many points does he need on his last test to raise his mean test score to 90 points?

so

[tex]\frac{x_1+x_2+x_3+x_4}{4} =90[/tex]

[tex]x_1+x_2+x_3+x_4=360[/tex] ----> equation B

substitute equation A in equation B

[tex]264 + x_4 = 360[/tex]

solve for x_4

[tex]x_4 = 360-264[/tex]

[tex]x_4 = 96[/tex]

Therefore

Kevin needs 96 points on his last test to raise his mean test score to 90 points.

Answer:

[tex]f(g( - 4)) = 196[/tex]

Step-by-step explanation:

The functions are;

[tex]f(x) = {x}^{2} [/tex]

and

[tex]g(x) = 3x - 2[/tex]

We want to find

[tex]f(g( - 4))[/tex]

First we find g(-4) to get:

[tex]g( - 4) = 3 \times - 4 - 2[/tex]

[tex]g( - 4) = - 12- 2[/tex]

[tex]g( - 4) = - 14[/tex]

Now

[tex]f(g( - 4)) = f( - 14)[/tex]

This implies that,

[tex]f(g( - 4)) = {( - 14)}^{2} [/tex]

[tex]f(g( - 4)) = {( - 14)} \times - 14[/tex]

[tex]f(g( - 4)) = 196[/tex]
