The solution to the problem is as follows:
If you use Ln you can get rid of e.
ln(e^0.4x) = ln(0.4)
0.4x = ln(0.4)
x = (ln(0.4))/0.4
<span>x = -2.29

17,000-8,700=$8,300 value after 3 years.
Answer:
Step-by-step explanation:
Step-by-step explanation:
ball is hit from the ground level i.e h0=0
initial velocity=80
when the ball hits the ground it's height from the ground=0
substitute the data in the above function
0=-16t^2+80×t+0
t=0 is a solution but it is at the beginning of the projection
16t=80
t=5
