Answer:
<em>B.) 12 ft</em>
Step-by-step explanation:
A square's sides are all the same: meaning, every side MUST be the same length. Then, all we have to do is find the square root of 144, which is 12.
To check this, we need to multiply the length times the height. If it equals 144, it is correct.
12 x 12 = 144
Hope I explained this well enough! If this seems confusing, or if you haven't learned square roots yet, you can always just try multiplying down the list of available choices to see what equals 144 c:
( 10 x 10 = 100, 12 x 12 = 144, 18 x 18 = 324, 36 x 36 = 936)

Step-by-step explanation:
Answer:
The first one. L (t) = 0.37t + 39.67
Step-by-step explanation:
The "0.37t" is about 0.37 years of life expectancy added for each year that passes the "+ 39.67" is the starting life expectancy that has to be added to whatever the rising trend may be. just multiply 0.37 by 20 and youl have the rising trend.
Answer:
a) Prey: 
Predator: 
b) they grow as a function y(1-y).
c) It will grow faster and probably exponentially,
Step-by-step explanation:
a)
Prey
For prey population the rate of change is given by its own growth rate, it would be a constant times the variable, minus the rate at which it is preyed upon, usually it is represent a parameter times x and y.
So the differential equation could be:

Predator
By the other hand, the rate of change of the predator's population depends only the rate at which the predators eat preys, minus predator's intrinsic death rate.

b) If there are no predators present the differential equation that models prey population will be:
So they grow as a function y(1-y).
c) In the case of the population of prey is much grader than predator, it will grow faster and exponentially, because it we assume that preys have unlimited food supply.
I hope it helps you!
