Answer:

y=8.9

Step-by-step explanation:

To solve this problem, we have to use the pythagorean theorem.

the formula for the pythagorean theorem is a²+b²=c²

(8)²+(y)²=(12)²

64+y²=144

y²=144-64

y²=80

y=√80

y=4√5

y=8.9

hope this helps!!

Mei Mei invested $1700 in an account that pays 3% interest compounded annually.
algol [13]

Answer:

$2728

Step-by-step explanation:

Use compound interest formula:

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

P = 1700, r = 0.03, n = 1, t = 16

Plug in numbers:

A = 1700(1 + \frac{0.03}{1})^{(1)(16)}

Simplify:

A = 1700(1.3)^{16

Use calculator:

A = 2728
