An initial population of 415
slamgirl [31]

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

I need help with this math
Nana76 [90]

Answer:

2/4 x 7/10 = 14/40, or 7/20.

5/6 x 3/4 = 15/24, or 5/8

3/4 x 2/3 = 6/12, or 1/2

3/10 x 4/5 = 12/50, or 6/25

i think you can finish the rest, all you have to do is multiply the numerator and the numerator, and the denominator and the denominator.

numerator = number on the top

denominator = number on the bottom

then put the two results:

[numerator x numerator]

____________________

[denominator x denominator]

hope this helped! ^^
