You are the manager of a rental car company. A customer, Sandy Furrow, has asked you for an estimate of charges for a nine day rental of an SUV. She expects to drive 670 miles. If the company charges $54.50 per day plus 15 1/ 2 cents per mile for this category of vehicle, what would be the total rental charge (in $) for Sandy's trip?

The functions are 1. f(x) = x⁴ and g(x) = cos (x), 2. f(x) = cos x and g(x) = cos x and 3. f(x) = cos (x) and g(x) = x⁴.

A function is a relation from a set A to a set B where the elements in set A only maps to one and only one image in set B. No elements in set A has more than one image in set B.

The composition of two functions f(x)  and g(x) can be defined as the new function h(x) such that h(x) = f(g(x)).

1. cos^4 (x) = f(g(x))

cos⁴ (x) can be written as (cos x)⁴

f(g(x)) = (cos x)⁴

Let g(x) = cos (x)

f(g(x)) = (g(x))⁴

Substitute x in place of g(x).

So, f(x) = x⁴

2. cos(cos(x)) = f(g(x))

Let g(x) be cos x

f(g(x)) = cos (g(x))

Substitute x in place of g(x),

f(x) = cos x

3. cos (x⁴) = f(g(x))

Let g(x) = x⁴

f(g(x)) = cos (g(x))

Substitute x in place of g(x),

f(x) = cos (x)

Hence each of the functions is found from the composition of functions.

The dilations relation is C'D = (3/4)CD.

Dilation of a figure will leave its sides get scaled (multiplied) by same number. That number is called the scale factor of that dilation.

Its also called scaling of a figure, but due the involvement of coordinates, it involves a center of a dilation, which is like a pinned point which stays at same place after dilation.

Its like we enlarge or shorten the size of the figure (or keep it same, when scale factor = 1).

Given;

First, we want to dilate point C using D as the center of dilation with a scale factor = 3/4.

This only means that we will have the new point C', such that:

This is  referred to Fermat's Little Theorem, which states that if p is a prime number and a is an integer such that 0 < a < p, then a^(p-1) ≡ 1 (mod p).

In other words, if we raise a to the power of p-1 and divide by p, the remainder will always be 1. This theorem can be used to efficiently test the primality of a number or to find modular inverses in modular arithmetic.

Fermat's Little Theorem is a fundamental result in number theory and has important applications in cryptography and computer science. The theorem states that if p is a prime number and a is an integer such that 0 < a < p, then a^(p-1) ≡ 1 (mod p). This can be expressed as:

a^(p-1) = 1 + kp where k is an integer.

This theorem is a direct consequence of the fact that the set of integers from 1 to p-1 (mod p) form a group under multiplication (mod p). This group is known as the group of units modulo p, and the order of this group is p-1. Hence, a^(p-1) must be congruent to 1 (mod p) since it is the product of all elements in the group.

You want to know which specification can result in an infinite number of triangles.

If only the angles are specified, the sides can have an infinite number of (related) lengths.

  three angles: 62°, 34°, and 84° will create an infinite number of triangles

Assuming the side lengths can form a triangle, they will specify exactly one triangle.

Lengths 3 cm, 5 cm, and 10 cm cannot form a triangle.

When two sides are specified along with the angle between them, exactly one triangle can be formed.

There are 8 nickels does Richard have.

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

We have to given that;

Richard has 17 coins with a value of 76 cents.

And, The coins are nickels, dimes, and pennies. He has twice as many pennies as dimes.

Now, Let p = number of pennies

n = number of nickels

d = number of dimes

Hence, We can formulate;

⇒ p(1) + n(5) + d(10) = 76

⇒ p + 5n + 10d = 76  .. (i)

Here, He has twice as many pennies as dimes.

⇒ p = 2d

And, Richard has 17 coins.

⇒ p + d + n = 17 .. (ii)

Substitute p = 2d in equation (i) and (ii),

⇒ p + 5n + 10d = 76  

⇒ 2d + 5n + 10d = 76  

⇒ 5n + 12d = 76  .. (iii)

⇒ p + d + n = 17

⇒ 2d + d + n = 17

⇒ n + 3d = 17  .. (iv)

Solve equation (iii) and (iv), we get;

⇒ d = 3

⇒ n = 8

Angle BAC is equal to 72 degrees, which is calculated by subtracting 2 times the angle of intersection between lines p and q (34 degrees) from 180 degrees.

Given that two lines p and q intersect at X at an angle of 34 degrees

Let A be a point inside the 34 degree angle formed by p and q

Then, let B be the reflection of A through line p, and let C be the reflection of A through line q

To find angle BAC,

we must first understand that a reflection of a point across a line results in an angle equal in measure to its original angle, but on opposite sides of the line of reflection.

In this case, because A is inside the 34 degree angle formed by lines p and q,

angle AXB must be equal to 34 degrees

angle AXC must also be equal to 34 degrees

Therefore, angle BAC must be equal to 180 degrees minus 2 times 34 degrees, or 72 degrees.

In conclusion, the angle BAC is equal to 72 degrees.

The 95% confidence interval for the population mean is approximately (1,218, 1,271)

A 95% confidence interval for the population mean can be calculated as follows:

Calculate the standard error (SE) of the mean: SE = standard deviation/sqrt (sample size) = 38 / sqrt(16) = 12.56

Use the t-distribution to find the critical value, t*, for a 95% confidence level and degrees of freedom (df) = sample size - 1 = 15.

Calculate the margin of error (ME) as ME = t* * SE = t* * 12.56.

Calculate the lower bound and upper bound of the confidence interval: lower bound = sample mean - ME = 1,245 - ME; upper bound = sample mean + ME = 1,245 + ME.

Since the degrees of freedom for this sample size is quite small, the critical value for t-distribution can be approximated using a t-table for a 95% confidence level and df = 15. The critical value is approximately 2.131.

So, the margin of error is ME = 2.131 * 12.56 = 26.86, and the 95% confidence interval for the population mean is:

Lower bound: 1,245 - 26.86 = 1,218 (rounded to the nearest whole number)

Upper bound: 1,245 + 26.86 = 1,271 (rounded to the nearest whole number)

Therefore, the 95% confidence interval for the population mean is approximately (1,218, 1,271).

Answer:

62.5 square feet

Step-by-step explanation:

Let's call the width of the rectangle w. Since the ratio of the length to the width is 5 to 2, the length can be expressed as 5/2 times the width:

l = 5/2 * w

We know the length is 12.5 feet, so we can use that information to solve for the width:

12.5 = 5/2 * w

w = 12.5 * 2/5

w = 5

The width of the rectangle is 5 feet.

The perimeter of the rectangle is calculated by adding up the lengths of all four sides:

p = 2 * (l + w)

p = 2 * (12.5 + 5)

p = 2 * 17.5

p = 35

The perimeter of the rectangle is 35 feet.

The area of the rectangle is calculated by multiplying the length and width:

a = l * w

a = 12.5 * 5

a = 62.5

The area of the rectangle is 62.5 square feet.
