This will be an obtuse angled triangle because one angle is greater than 90 degrees.
The answer is about 113.1 feet squared
<em><u>Option A</u></em>
<em><u>The solution is:</u></em>

<em><u>Solution:</u></em>

We have to solve the equation f(x) = 0
Let f(x) = 0

Solve the above equation


Take square root on both sides

Thus the solution is found
70-40= 30
30/2 = 15
40/2= 20
15 x 20 = 300
Answer:
5 years
Step-by-step explanation:
If the population of penguins is given by the function:

Initial Size =
Triple its Initial Size, P(t)=
Therefore:

It therefore takes 5 years for the penguin population to triple in size.
