Answer:
$4,500
Step-by-step explanation:
For simple interest,
I = prt,
where
I = interest
p = principal
r = annual interest rate
t = number of years
We have p = $5,000, r = 9% = 0.09; t = 1 year
I = $5,000 × 0.09 × 1
I = $450

Answer:
8 seconds
Step-by-step explanation:
Given
h = - 5t² + 40t
When the object hits the ground then h = 0
Substitute h = 0 into the function and solve for t
- 5t² + 40t = 0 ← factor out - 5t from each term
- 5t(t - 8) = 0
Equate each factor to zero and solve for t
- 5t = 0 ⇒ t = 0
t - 8 = 0 ⇒ t = 8
t= 0 denotes the time of launch
t = 8 denotes the time it hits the ground
