Apopulation of 200 animals is decreasing by 4% per year. at this rate, in how many years will the population be less than 170?

In the question , it is given that the population is decreasing by 4% per year .

So we have to use the following formula of exponential decay:

Substituting the given values, we will get

Dividing both sides by 200

Taking log on both sides

Dividing both sides by log(0.96)

t = approx 4 years

So after 4 years , the population will be less than 170.

part a

in a city ice cream is mostly only bought when the temperature is very high as ice cream cools down our

so we can derive the conclusion that as the temperature increases the number of ice creams sold also increases

part b

y intercept is 5

slope is 2
