Answer:
37.84 years
Step-by-step explanation:
We apply the compound interest formula;
A = P(1+r)^n
In this case we have;
A = 11,900
P = 1,200
r = 6.25% p.a
We substitute these values into the above equation and solve for n, the number of years required.
11900 = 1200(1.0625)^n
9.91667 = 1.0625^n
n = 37.84 years
Answer:
f(t) = 15.06 m
Step-by-step explanation:
The relationship between the height of the rocket and the time after launch, t. In seconds is given by :
We need to find the maximum height the rocket will reach the ground.
When it reaches the ground,
f(t) = 0
So,
Maximum height,
f'(t) = 0
Put t = 1.63 in equation (1).
So, the maximum height of the rocket is 15.06 m.
