Answer:
The exponential function to model the duck population is:
f(n)=415*(1.32)^n, where:
x is the duck population
n is the number of years
Step-by-step explanation:
In order to calculate the duck population you can use the formula to calculate future value:
FV=PV*(1+r)^n
FV=future value
PV=present value
r=rate
n=number of periods of time
In this case, the present value is the initial population of 415 and the rate is 32%. You can replace these values on the formula and the exponential function to model the duck population would be:
f(n)=415*(1+0.32)^n
f(n)=415*(1.32)^n, where:
x is the duck population
n is the number of years
X>_0 y>_-4 your domain is the opposite of whats inside of the radical, in this case it’s zero but if the number was -5 you would say x>_ 5. Your range is whatever number is in the back, which is negative 4. But you have to pay attention, if there is a negative before the radical your range will be y<_ the number. But here, there isn’t a negative sign in the front of the radical so it’s just y>_ -4.
Answer:
the dividend and divisor were both multiplied by 100
and
the quotient of both expressions is 3
hope this helped
explanation: move the decimal points for the first expression to make them whole numbers and divide the expressions for the quotient!
A times b
(or multiplied by)
