Answer:
a) P(t) = 330 
b)P(t) →population after t years.
t →number of years.
c) Number of deer after five years = 556
Step-by-step explanation:
a) The population increasing at an annual rate of 11%, means the population is being multiplied by 1.11 each year.
So, we can use the formula
P(t) = P 
P(t) = 330 
P(t) = 330 
b) In this model
P(t) → population after t years
P → present population
r → annual increasing rate
c) Number of population after 5 years is,
P(5) = 330 
= 556
Number of deer after 5 years = 556
You are asked to find the missing value in
... 40 + ? = 70
given that it is also the solution to
... ? + 5 = 35
Either way, you subtract the constant that is on the same side of the equation as the unknown.
... 40 + ? - 40 = 70 - 40
... ? = 30 . . . . the missing value
_____
You can check to see if this also satisfies the equation
... 30 + 5 = 35 . . . . . . . true
12.9 = x + 7.1
subtract 7.1 from both sides to isolate the variable, x.
5.8 = x
5.8 is your answer.
I'm assuming 43 is actually 4/3
see what number the previous term must be multiplied by to get the next term
4 *something = 12, 12*something=36
common ratio is 3
