Answer:

centre is (8, -5)

r =  \sqrt{ {g}^{2} +  {f}^{2}  - c }  \\  =  \sqrt{64 + 25 - 80}  \\  =  \sqrt{9}  \\ r = 3 \\ radius \:  =  \: 3 \: units

$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%.

a spinner is divided into eight equal parts numbered 1 to 8. if the spinner is spun once, what is the probability that it stops
Step2247 [10]
Since the total number of available selections is divided by two, the probability is 50%.  If we look at the total set of numbers, we find that even numbers are multiples of 2.  2, 4, 6, 8 (which makes up half of the numbers on the spinner).
