Answer:
t = 5 seconds
Step-by-step explanation:
It is given that, the height h, in feet of a ball above the ground is given by :
Where t is in seconds
We need to find how long does it take the ball to hit the ground? When it hits the ground, its height will be equal to 0. So,
Neglecting negative time.
It means ball will take 5 seconds to hit the ground.
Answer:
population will be 79806.
Step-by-step explanation:
Population of a town 4 years ago was 50,000
Population of town had grown exponentially and present population is 63,124.
So the formula of the population growth will be
Where = Final population n = number of years.
= Initial population
r = rate of increase in population per year.
so 63124 = 50,000
= 1.0813
Now we have to find the population after 4 years from now.
=
=
= 63124 × 1.264
= 79806
Therefore, after 4 years from now population will be 79806.
