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: C) $1951.53
<u>Step-by-step explanation:</u>

- A is amount accrued (final balance)
- P is the Principal (original amount deposited)
- r is the rate (in decimal form)
- t is the number of years
A=1500(1+0.068)⁴
= 1500(1.068)⁴
= 1951.53
Set up an equation of ratios as shown below:
h 24 ft 4
----- = ---------- = ---
4 6 ft 1
Cross multiplying the 1st and 3rd fractions, we get h=16 ft (answer)
A whole number is a number that is whole as in 1,2,3,4,etc, they don’t have decimals. To find the whole number for these questions you must look at the places (hundreds, thousands, ten thousands.) I was always told a trick which is 4 or less let it rest, 5 or more let it sore. (Basically if it’s less than 4 then decrease it, if it’s higher than increase it.)
12.496 = 13
2.90 = 3
Your answers are 13 and 3.
