Naily [24]

Answer:

{9, 7, 5, 3, 1}

Step-by-step explanation:

All you do is plus in each domain value in for the x and you get the range every time.

-2(-2)+5

-2(-1)+5

-2(0)+5

$650 is invested in an account earning 8.6% interest (APR), compounded monthly. Write a function showing the value of the accoun

IRISSAK [1]

Answer:

The value of the acount after t years is of $A(t) = 650(1.0072)^{12t}$

The annual growth rate is of 0.72%.

Step-by-step explanation:

Compound interest:

The compound interest formula is given by:

$A(t) = P(1 + \frac{r}{n})^{nt}$

Where A(t) is the amount of money after t years, P is the principal(the initial sum of money), r is the interest rate(as a decimal value), n is the number of times that interest is compounded per year and t is the time in years for which the money is invested or borrowed.

$650 is invested in an account earning 8.6% interest (APR), compounded monthly.

This means that $P = 650, r = 0.086, n = 12$ . So

$A(t) = P(1 + \frac{r}{n})^{nt}$

$A(t) = 650(1 + \frac{0.086}{12})^{12t}$

$A(t) = 650(1.0072)^{12t}$

The value of the acount after t years is of $A(t) = 650(1.0072)^{12t}$

Annual growth rate

1.0072 - 1 = 0.0072 = 0.72%

The annual growth rate is of 0.72%.

Find the area of the shaded regions. Give your answer as a completely simplified exact value in terms of π (no approximations).

Anna [14]

The shaded areas add to 2/5 of the area of the circle, which is given by
A = πr²

Then the shaded area is ...
(2/5)A = (2/5)π(10 in)²
shaded area = 40π in²
