Awildlife biologist determines that there are approximately 200 deer in a region of a national park. the population grows at a rate of 7% per year. what is an exponential function that models the expected population?

a. f(x) = 200(0.07)x
b. f(x) = 200(1.07)x
c. f(x) = 1.07(200)x
d. f(x) = 7(200)x

The exponential function that models the expected population of deer in the region of national park is  

hence option (B) is correct

Given

A wildlife biologist determines that there are approximately 200 deer in a region of a national park.

The population grows at a rate of 7% per year.

We have to determine is an exponential function that models the expected population.

The general exponential function is given by the  equation (1)

Initial number of deer = a = 200

r = Yearly growth rate = 7%

On putting  the values in equation (1) we get

So the exponential function that models the expected population of deer in the region of national park is  

hence option (B) is correct.

Option B.

Step-by-step explanation:

A wildlife biologist determines that

Initial population of deer = 200

Growth Rate = 7% = 0.07

The general exponential growth function is

where, a is initial value, r is growth rate and x is number of years.

Substitute a=200 and r=0.07 in the above function.

The exponential function that models the expected population is .

Therefore, the correct option is B.

to find the perimeter of the rectangle this is the expression:

x-9+x-9+3x-4+3x-4=138

if we simplify it:

8x-26=138

remember, 138 is what it all adds up to

the length is 11.5cm

the width is 57.5cm

the area is 661.25cm^2

the answers might not be correct use at own risk

hit or miss i guess they never miss huh
