Answer:
$3.296
Step-by-step explanation:
Simple interest=PRT/100
P=Principal=$20.600
R=rate=8%
T=time=2yrs
=20.600×8/100×2
=$3.296
If the ball hit the ground it means that its height is equal to 0. In order to find the time after the ball <span>will hit the ground, we need to find the solution of the equation h(x)=0 which is different to 0.
-4.9x^2+21.3x=0
x(-4.9x+21.3)=0
-4.9x+21.3=0
x=21.3/4.9 = 4.3469 seconds</span>
