Answer:
After 9 years, the population reach 4000.
Step-by-step explanation:
The given function P(t) represents the size of a small herbivore population at time t (in years).
We need to find the number of years after which population reach 4000.
Substitute P(t)=4000 in the above function.
Divide both sides by 1000.
Taking ln on both sides.
![[\because \ln e^x=x]](https://tex.z-dn.net/?f=%5B%5Cbecause%20%5Cln%20e%5Ex%3Dx%5D)
Divide both sides by 0.16.
We need to find the number of years. So, round the answer to the next whole number.
Therefore, after 9 years, the population reach 4000.
Answer:
x=2
Step-by-step explanation:
Isolate the variable by dividing each side by factors that don't contain the variable :)
Answer:
r = 72
Step-by-step explanation:
Given that:
r/4=18
Multiplying both sides by 4
r = 18*4
r = 72

Answer,
<em>(26/2) * 3</em>
<em>= 39</em>
Explanation,
<u><em>26 cookies is only 2/3 of 3/3. So, we divide 26 by 2 to see how many cookies are in 1/3. We then can find out that when you make 1/3 of the cookies there are 13. Since that is only 1/3 and we want to find out 3/3. We multiply 13 by 3 and get 39 which is all the cookies she planned to make.</em></u>
