Answer:
Step-by-step explanation:
We have been given that there are 170 deer on a reservation. The deer population is increasing at a rate of 30% per year.
We can see that deer population is increasing exponentially as each next year the population will be 30% more than last year.
Since we know that an exponential growth function is in form: , where a= initial value, r=growth rate in decimal form.
It is given that a=170 and r=30%.
Let us convert our given growth rate in decimal form.
Upon substituting our given values in exponential function form we will get,
Therefore, the function will give the deer population P(t) on the reservation t years from now.
If the proportion of iris to roses in Nikki's garden is 2: 5, it means that for 25 roses: (2/5) = (10/25). Therefore to maintain the proportion by adding 20 roses: (2/5) = (18/45). The number of irises after the addition of roses will be 10 + 18 = 28 irises.
