Answer:
t = 4 seconds
Step-by-step explanation:
The height of a soccer ball as a function of time is given by :
We need to find the time when the ball hit the ground i.e. h = 0
Put h = 0 in above equation. So,
It is a quadratic equation such that,
t = -1 s and t = 4 s
Neglecting -1 s, the ball will hit the ground after 4 seconds.
Answer:
$360
Step-by-step explanation:
To calculate simple interest (I) use the formula
I =
Where P is the principal (deposit), R is the rate of interest and T is time in years.
here P = 3000, R = 4 and T = 3, hence
I = =
= $360
