The compositions are:

f * f(x) = x⁴ - 2x²

g * g(x) = 81/64x

To find the composition f * f, we start by substituting f(x) into f(x) wherever we see x:

f * f (x) = f(f(x)) = f(x² - 1) = (x² - 1)² - 1

Expanding the expression, we get:

f * f (x) = x⁴ - 2x² + 1 - 1 = x⁴ - 2x²

So, f * f(x) = x⁴ - 2x².

To find the composition g * g, we substitute g(x) into g(x) wherever we see x:

g * g (x) = g(g(x)) = g(9/8x) = 9/8(9/8x) = 81/64x

So, g * g(x) = 81/64x.

e. None of the above.

what is algebra?

Algebra is a branch of mathematics that deals with mathematical operations and symbols used to represent numbers and quantities in equations and formulas.

To check whether the relation is functional, we need to make sure that each x-value is associated with only one y-value.

We can see that the pairs (6,7), (-2,9), (8,8), and (-4,9) all have different x-values, and therefore are associated with different y-values. This means that the relation is currently functional.

To determine which ordered pair could not be substituted so that the relation is functional, we need to find an x-value that is associated with two different y-values.

Let's look at each of the answer choices and see if they fit this criteria:

a. (9,9): This pair does not already appear in the relation, so it's possible that it could be added without affecting the functionality of the relation.

b. (2,9): This pair does not already appear in the relation, so it's possible that it could be added without affecting the functionality of the relation.

c. (7,8): This pair does not already appear in the relation, so it's possible that it could be added without affecting the functionality of the relation.

d. (8,3): This pair does not already appear in the relation, so it's possible that it could be added without affecting the functionality of the relation.

Answer:The amount of a 80% acid solution that must be mixed with a 55% solution to produce 600 mL of a 60% solution can be calculated using a simple algebraic equation. Let x represent the amount of the 80% acid solution in mL that needs to be mixed with the 55% solution.

The equation can be set up as follows:

0.80x + 0.55(600 - x) = 0.60(600)

Step-by-step explanation: The left-hand side of the equation represents the total amount of acid in the mixture. The first term, 0.80x, represents the amount of acid from the 80% solution, and the second term, 0.55(600 - x), represents the amount of acid from the 55% solution. The right-hand side of the equation represents the total amount of acid in the final 60% solution, which is 60% of 600 mL.

By solving this equation for x, we can determine the amount of the 80% acid solution that needs to be mixed with the 55% solution. Once we have the value of x, we can then calculate the amount of the 55% solution by subtracting x from 600 mL.

Now we know that the pure acid in the 80% solution (0.80x) plus the amount of pure acid in the 30% solution ((0.30)(600-x)) has to equal the amount of pure acid in the final mixture(0.40*600), so our equation to solve is:

0.80x+0.30(600-x)=0.40*600 get rid of parens

0.80x+180-0.30x=240 subtract 180 from each side

0.50x=60 divide each side by 0.50

x=120 ml---------------------amount of 80% solution needed

What is inequalities?

In mathematics, an inequality is a mathematical statement that indicates that two expressions are not equal. It is a statement that compares two values, usually using one of the following symbols: "<" (less than), ">" (greater than), "≤" (less than or equal to), or "≥" (greater than or equal to).

The correct set of inequalities that model the constraints on the composition of the student body are:

600 ≤ a ≤ 700 (the number of underclassmen must fall between 600 and 700, inclusive)

500 ≤ b ≤ 600 (the number of upperclassmen must fall between 500 and 600, inclusive)

a + b ≤ 1200 (the total number of students cannot exceed 1200)

Note that the inequalities 600 < a < 700 and 500 < b < 600 are not correct, as they do not take into account the inclusive limits of the ranges for the number of underclassmen and upperclassmen.

according to the question the balance in the account earning compound interest after 6 years is $4,156.22.

Multiply the principal with the rate of interest, the time period, and various other factors to determine simple interest. Simple returns = money + interests + hours is the marketing formula. This approach makes calculating interest the simplest. The approach to calculating interest that is most usually employed is as a percentage over the principal sum. For instance, he will just pay his share of the interest at 100% when he borrows $100 with a friend and agrees to shell out it back with 5% interest. $100 has been reduced to $5 (0.05). Every time you borrow money, you must pay interest, which is applied to whatever loans you make. On the loan balance, interest is typically calculated using an annual percentage.

given,

To calculate the balance in the account earning compound interest after 6 years, we can use the formula for compound interest:

A = P(1 + r/n)^(nt)

Where:

A = the sum of money at the end of the period of time

P stands for the principle (beginning sum).

the decimal representation of the annual interest rate (r).

n represents how many times the interest rate is compounded annually.

t is the duration (in years).

In this case, we have:

P = $3500 (the principal)

r = 2.16% = 0.0216 (the annual interest rate)

Since interest is compounded four times a year (quarterly), n is equal to four.

t = 6 (the time period is 6 years)

With these values entered into the equation, we obtain:

A = 3500(1 + 0.0216/4)^(4*6)

A = $4,156.22

Compound interest is the term used to describe the interest that is calculated on both the initial investment and any accumulated interest. It is interest on top of interest, to put it another way.

We can use the formula for compound interest to find the balance in the account after 6 years:

A = P(1 + r/n)^(nt)

where:

A = balance after 6 years

P = principal = $3500

r = annual interest rate = 2.16%

n = number of compounded times  per year = 4 (quarterly)

t = time in years = 6

Step-by-step explanation:

function declines at a constant rate of 1/2x with a y-intercept of 20 giving the equation y= 1/2x + 20

Answer:

-36

Step-by-step explanation:

To solve this problem, we need to integrate f'(x) to find f(x), and then evaluate f(3) and f(-1) to compute the expression f(3) - f(-1).

Integrating f'(x)=-4x - 5 with respect to x, we get:

f(x) = -2x^2 - 5x + C

Where C is the constant of integration.

To find the value of C, we can use the initial condition f(0) = 1. Substituting x = 0 and f(x) = 1 into the equation above, we get:

1 = -2(0)^2 - 5(0) + C

1 = C

So, we have:

f(x) = -2x^2 - 5x + 1

Now, we can evaluate f(3) and f(-1) and compute f(3) - f(-1):

f(3) = -2(3)^2 - 5(3) + 1 = -32

f(-1) = -2(-1)^2 - 5(-1) + 1 = 4

f(3) - f(-1) = (-32) - 4 = -36

Therefore, f(3) - f(-1) = -36.

As a general rule, a circle is a shape with all points on its boundary equidistant from a central point called the center

In this case, the center is point W

The sum of angles on the circumference is 360

So, we have

17x - 20 + 75 + 2 * 59 = 360

Evaluating the like terms, we have

17x = 187

Divide by 17

x = 11

Hence. the value of x is 11

The amount (coupon interest) that is earned off the $1,000 bond with 4.3% coupon every 6 months is $21.50.

The coupon interest represents the periodic payment received by a bondholder from the date of issuance until the date of maturity of a bond.

The coupon interest is computed by applying the coupon rate on the face value of the bond.

Face value of the bond = $1,000

Coupon interest rate = 4.3%

Maturity period = 30 years

Coupon (bond) interest for 6 months = $21.50 ($1,000 x 4.3% x 6/12)
