Answer:
a) P(t) = 330
b)P(t) →population after t years.
t →number of years.
c) Number of deer after five years = 556
Step-by-step explanation:
a) The population increasing at an annual rate of 11%, means the population is being multiplied by 1.11 each year.
So, we can use the formula
P(t) = P
P(t) = 330
P(t) = 330
b) In this model
P(t) → population after t years
P → present population
r → annual increasing rate
c) Number of population after 5 years is,
P(5) = 330
= 556
Number of deer after 5 years = 556
Here speed of first train is slower than speed of second train. So if they catch up , the distance traveled will be same since they left the same station at different times.
But the time traveled will be different .
Let us say the two trains meet at time t ,
Distance = speed * time
Distance traveled by first train = 40 t
Since second train is leaving after three hours , so
Distance traveled by second train = 60(t-3)
As discussed earlier, distance traveled will be same, so
distributing 60 over t-3
t=9
So the second train will meet the first at 9 p.m.
