Which of the following statements is true about the function presented in the table?

Lynna [10]

Answer:

C. The slope of the function is -2 and the y-intercept is 4.

Explanation:

The y-intercept is the point when x = 0. On the table when x is 0, y is 4.

The slope of the function is -2 because the y value is going down by 2 for each +1 of x.

x │ y

-2 │ 8

0 │ 4

↓ +1 ↓ -2

1 │ 2

↓ +1 ↓ -2

2 │ 0

$765.13 is deposited at the end of each month for 3 years in an account paying 2% Interest compounded monthly. Find the final am

Crank

Answer:

Option B.

Step-by-step explanation:

The future value formula, for an annuity, is:

$FV = \frac{P((1+r)^{n} - 1)}{r}$

An annuity means that a number of payments happen during the period(an year, for example).

P is the value of the deposit, r is the interest rate, as a decimal, and n is the number of deposits.

In this question:

Deposits of $765.13, so $P = 765.13$

Each month, for 3 years. An year has twelve months, so $n = 3*12 = 36$

2% Interest a year. An year has 12 months, so $r = \frac{0.02}{12} = 0.00167$

Find the final amount of the account.

$FV = \frac{765.13*((1 + 0.00167)^{36} - 1)}{0.00167} = 28,363.46$

The final amount of the account will be $28,363.46, which is option B.
