A ratio between is like 52
An ??????
Well to figure this out, we will use mathematics. You do 90% of the an and then do 39 which is close to 90 and then because it has 9 in the number that is given. So, 213 is incorrect. 90% of the things like 213, = 39. And if it equals 39, then here comes 90. 90 comes in as a number to help, but 213 does to. So we will divide the number 9. 9 = 2, and since 213 has the first digit 2 in the number, that means that the answer is An number that equals 2 is the common side of two consecutive angles in a polygon.
Just a answer!
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
Answer:
I think its 8a because in a regular octagon we have 8 sides.
You are adding by 5 in the sequence.
If f(1) is -7
f(2) = -2
f(3)= 3
f(4)=8
f(5)=13
f(6)=18
Therefore, f(7)=23
