1. Marcus is playing hang-glider catch while gliding along in a hang-glider. He and his friend, Aurelius, are tossing a ball back
and forth to each other as they fly 100 feet above the ground.
Aurelius is distracted by a passing pelican and drops the ball. The
height, h, in feet, of the ball above the ground is given by the
formula h(t) = -16t2 + 100, where t is the time in seconds.
To the nearest tenth of a second, after how many seconds does the
ball hit the ground?

the answer is 200

step-by-step explanation:

the way the question is worded, it seems to imply the $264 interest is simple interest, not compound interest.

the simple interest for 2 years is $264; the simple interest for 1 year is $132.

$132 interest on a $600 investment means an interest rate of (132/600)*100 = 22%.

the value of $200 at 22% interest compounded annually for three years is

200%281.22%29%5e3

the amount of interest is that value, minus the original $200.
