So, (f o h)(-3) = 3. This is the value of the composite function (f o h) at -3. Please note that (f o h)(-3) is equivalent to f(h(-3))

An input and an output are connected by a function. It functions similarly to a machine with an input and an output. Additionally, the input and output are somehow connected. The traditional format for writing a function is f(x) "f(x) =... "

To find (f o h)(-3), we need to first evaluate h(-3), and then plug that result into the function f(x).

Given:

f(x) = -2x - 1

h(x) = -x - 5

First, we evaluate h(-3):

h(-3) = -(-3) - 5

h(-3) = 3 - 5

h(-3) = -2

Now, we plug the result of h(-3) into the function f(x):

f(h(-3)) = f(-2)

f(h(-3)) = -2(-2) - 1

f(h(-3)) = 4 - 1

f(h(-3)) = 3

So, (f o h)(-3) = 3. This is the value of the composite function (f o h) at -3. Please note that (f o h)(-3) is equivalent to f(h(-3)), which means we first evaluate h(-3) and then plug that result into f(x). I hope this helps! Let me know if you have any further questions. :)

Step-by-step explanation:

It is not clear from the given information which angles and sides are being referred to as "107⁰", "-x-8", "-42-7", and "3y-1". However, we can use some properties of rhombuses to solve for x, y, and z.

Opposite angles in a rhombus are equal. Therefore, if one angle is 107⁰, then the opposite angle is also 107⁰.

The diagonals of a rhombus are perpendicular bisectors of each other. This means that they intersect at a right angle and divide each other into two equal parts.

The diagonals of a rhombus bisect each other's angles. This means that the angles formed by each diagonal with the sides of the rhombus are equal.

Using these properties, we can set up some equations to solve for x, y, and z:

Let's assume that "-x-8" and "-42-7" are the lengths of the diagonals of the rhombus, and that "3y-1" is the length of one of the sides.

Since the diagonals bisect each other's angles, we know that the angles formed by each diagonal with the side of the rhombus are equal. Let's call each of these angles "z":

-z + 107⁰ + z = 180⁰ (sum of angles in a triangle)

107⁰ = 180⁰ - 2z

2z = 73⁰

z = 36.5⁰

Now let's use the fact that the diagonals are perpendicular bisectors of each other:

(-x-8)/2 = (-42-7)/2

-x-8 = -49

-x = -41

x = 41

Finally, let's use the fact that the sides of a rhombus are equal:

-x-8 = 3y-1

41-8 = 3y-1

33 = 3y

y = 11

Therefore, the values of x, y, and z in the rhombus are:

x = 41

y = 11

z = 36.5⁰

A)The volume of cat food in the can is 9.62 cubic inches .

B) A ratio to show cubic inches to ounces is 4.83.

What is a cylinder?

A cylinder is a three-dimensional geometric shape that has two congruent circular bases connected by a curved surface.

The volume of a cylinder can be calculated using the formula

=> [tex]V = \pi r^2h,[/tex]

where r is the radius of the circular base, h is the height of the cylinder, and π is the mathematical constant pi (approximately equal to 3.14).

To find the volume of the cat food in the can, we need to use the formula for the volume of a cylinder,

Since the diameter is 3.5 inches, the radius is half of that, which is 1.75 inches. The height is 1 inch.

So,[tex]V=3.14\times(1.75)^2\times1[/tex] = 9.62 cubic inches (rounded to the nearest hundredth).

Therefore, the volume of cat food in the can is approximately 9.62 cubic inches.

Now ,To find the ratio of cubic inches to ounces,

Since the can holds 5.8 ounces of cat food, we can find the volume of cat food in cubic inches by dividing the weight by the density:

=> 5.8 ounces / 1.2 ounces per cubic inch

= 4.83 cubic inches (rounded to the nearest hundredth).

Therefore,  a ratio to show cubic inches to ounces is 4.83.

The utility company will have to increase its generating capacity by approximately 185.3% to meet the expected increase in electricity consumption over the next decade.

The problem involves the use of the exponential growth formula in mathematics, where we are given the current consumption of electricity in a city and we are asked to find the expected consumption of electricity after a certain period of time, assuming a fixed annual growth rate.

We can use the formula:

Here we have

A utility company in a western city in the United States expects the consumption of electricity to increase by 11%/year during the next decade, due mainly to the expected increase in population.

Let C₀ be the current consumption of electricity in the western city of the United States, and let C₁₀ be the expected consumption of electricity at the end of the decade.

We can use the following formula to calculate C₁₀:

C₁₀ = C₀ × (1 + r)ⁿ

Where r is the annual growth rate, n is the number of years

The amount by which the utility company will have to increase its generating capacity in order to meet the needs of the area at the end of the decade is given by the difference between C₁₀ and C₀

That is:

Amount of increase = C₁₀ - C₀

Substituting the values given in the problem, we get:

C₁₀ = C₀ (1 + 0.11)¹⁰

C₁₀/C₀ = (1.11)¹⁰

C₁₀/C₀ = (1.11)¹⁰

C₁₀ = C₀ × 2.84

Therefore, the amount by which the utility company will have to increase its generating capacity in order to meet the needs of the area at the end of the decade is:

Amount of increase =C₁₀ - C₀ = 2.853 × C₀ - C₀ = 1.853 × C₀

Therefore,

The utility company will have to increase its generating capacity by approximately 185.3% to meet the expected increase in electricity consumption over the next decade.

Answer:

the correct answer is option B.

Step-by-step explanation:

We can use the formula for the margin of error for a confidence interval for a population mean with a known population standard deviation:

Margin of error = z*σ/√n

where z is the critical value from the standard normal distribution for the desired confidence level (95% in this case), σ is the population standard deviation, and n is the sample size.

We are given that the margin of error is $135 and σ is $538. We need to find the sample size, n. To do this, we first need to find the appropriate value of z for a 95% confidence level. Using a standard normal distribution table or calculator, we can find that z = 1.96.

Substituting the values into the margin of error formula and solving for n, we have:

$135 = 1.96*($538)/√n

Squaring both sides and solving for n, we get:

n = [1.96*($538)/$135]^2 ≈ 62

Therefore, a sample size of 62 business students must be randomly selected to estimate the mean monthly earnings of business students at one college with 95% confidence that the sample mean is within $135 of the population mean, assuming the population standard deviation is known to be $538.

So the correct answer is option B.

The GPA corresponding to the 70th percentile at the college is approximately 3.246 based on standard deviation.

We can use the conventional normal distribution table or a calculator with a normal distribution function to determine the 70th percentile of GPAs at a college, which are normally distributed with a mean of 2.9 and a standard deviation of 0.6.

The inverse normal distribution function with a mean of 2.9, a standard deviation of 0.6, and a percentile of 70 can be used on a calculator. This results in:

[tex]3.246 for invNorm(0.7, 2.9, 0.6).[/tex]

As a result, the GPA that represents the 70th percentile is roughly 3.246.

We can determine the z-score corresponding to the 70th percentile, which is 0.5244, by using a common normal distribution table. Thus, we may apply the equation z = (x - ) /, where x is the GPA that corresponds to the 70%ile, is the mean, and is the standard deviation, and all three variables have values of 2.9. After finding x, we obtain:

0.5244 = (x - 2.9) / 0.6

x = 3.246

Once more, doing so yields the same outcome as using a calculator.

In conclusion, the GPA at the college that represents the 70th percentile is roughly 3.246.

Assuming that Dean has used the $4,300 as a down payment, his loan amount would be the total cost of the car minus the down payment, which is not given in the question.

However, assuming that the loan amount is $15,000 (which would be the case if the total cost of the car was $19,300), the monthly payment would be $284.89.

To calculate the total amount that Dean pays for the car over the course of the loan, we can multiply the monthly payment by the number of payments (60 payments over 5 years) and add the down payment:

Total amount = (Monthly payment x Number of payments) + Down payment

Total amount = ($284.89 x 60) + $4,300

Total amount = $17,093.40

A rectangle is a quadrilateral with four right angles, opposite sides that are parallel, and equal in length. It is a type of parallelogram where the adjacent sides are equal in length, but the opposite sides are not necessarily equal.

Let's start by using the formula for the perimeter of a rectangle:

Perimeter = 2(length + width)

We know that the perimeter is 34 feet, so we can plug in that value and simplify:

34 = 2(l + w)

17 = l + w

We also know that the length is 5 more than 2 times the width, so we can write an equation for that:

l = 2w + 5

We can substitute this expression for l into the first equation:

17 = (2w + 5) + w

The probability that the duration is at least 4 is 0.0053 (rounded to four decimal places).

Probability is represented by a number between 0 and 1, with 0 denoting an impossibility and 1 denoting a certainty.

(a) Let X be the duration of the contest. Then X can take values from 1 to 6, where 1 indicates that A or B wins the first game, and 6 indicates that the contest ends in a draw after 5 successive draws.

We can find the PMF of X by considering the possible outcomes for each value of X.

P(X = 1) = P(A wins) + P(B wins) = 0.2 + 0.5 = 0.7

P(X = 2) = P(A loses, B loses, A wins or B wins) = 0.3 * 0.3 * (0.2 + 0.5) = 0.054

P(X = 3) = P(A loses, B loses, A loses, B loses, A wins or B wins) = [tex]0.3^4[/tex] * (0.2 + 0.5) = 0.01323

P(X = 4) = P(A loses, B loses, A loses, B loses, A loses, B loses, A wins or B wins) = [tex]0.3^6[/tex] * (0.2 + 0.5) = 0.00243

P(X = 5) = P(A loses, B loses, A loses, B loses, A loses, B loses, A loses, B loses, A wins or B wins) = [tex]0.3^8[/tex] * (0.2 + 0.5) = 0.0004374

P(X = 6) = P(5 successive draws) = [tex]0.3^5[/tex] = 0.00243

Therefore, the PMF of X is:

X 1 2          3          4         5                 6

P(X) 0.7 0.054 0.01323 0.00243 0.0004374 0.00243

(b) To find the probability that the duration is at least 4, we need to add the probabilities of X = 4, X = 5, and X = 6.

P(X >= 4) = P(X = 4) + P(X = 5) + P(X = 6) = 0.00243 + 0.0004374 + 0.00243 = 0.0052974

For acute angles A and B it is known that sin A - 28/53 and tan B = 4/3. , , the value of cos(A+B) in simplest form is -15/53.

In geometry, an angle is the measure of the amount of turn between two lines that intersect at a point, called the vertex of the angle. Angles are typically measured in degrees, but can also be measured in radians.

Angles can be classified based on their measures. An angle that measures less than 90 degrees is called an acute angle, while an angle that measures exactly 90 degrees is called a right angle. An angle that measures greater than 90 degrees but less than 180 degrees is called an obtuse angle, while an angle that measures exactly 180 degrees is called a straight angle. Finally, an angle that measures greater than 180 degrees but less than 360 degrees is called a reflex angle.

We can start by using the identity:

cos(A + B) = cos A cos B - sin A sin B

To find cos A and sin A, we can use the identity:

sin² A + cos² A = 1

sin A = √(1 - cos² A)

We are given sin A = 28/53, so we can solve for cos A:

sin² A + cos² A = 1

(28/53)² + cos² A = 1

cos² A = 1 - (28/53)²

cos A = ± √[(53/53)² - (28/53)²]

Since A is acute, we take the positive root:

cos A = √(1 - (28/53)²)

To find sin B and cos B, we can use the identity:

tan B = sin B / cos B

We are given tan B = 4/3, so we can solve for sin B and cos B using the Pythagorean identity:

sin² B + cos² B = 1

sin B = (4/3) cos B

(4/3)² cos² B + cos² B = 1

cos² B = 1 / ((4/3)² + 1)

cos B = √(1 / ((4/3)² + 1))

sin B = (4/3) cos B

Now we can substitute all of these values into the formula for cos(A + B):

cos(A + B) = cos A cos B - sin A sin B

cos(A + B) = √(1 - (28/53)²) √(1 / ((4/3)² + 1)) - (28/53) (4/3) √(1 / ((4/3)² + 1))

cos(A + B) = (√((53² - 28²) / 53²)) (√(9 / (16 + 9))) - (4/3) (28/53) (√(9 / (16 + 9)))

cos(A + B) = (45/53) (√(9/25)) - (112/265) (√(9/25))

cos(A + B) = (9/53) - (24/53)

cos(A + B) = -15/53

Therefore, cos(A + B) = -15/53.
