Answer:

Step-by-step explanation:
-We can use the exponential decay function to estimate the size after 13 years:

Where:
is the size after t years, t is the time, r is the rate of decay and
the original size.
#We substitute and calculate as:

Hence, the forest covers
after 13 years.
No because its explain how much cumulative tip total on day 5 so the answer is D.400
Answer:

Step-by-step explanation:

The first set of parentheses is unnecessary, so it can just be removed.

To remove the second set of parentheses, you must distribute the negative sign that is to its left. It changes every sign inside the parentheses.

Now you combine like terms.



The slope perpendicular to 1/4 or .25 is 4.
Then you would use point slope form to write the equation.
Then you could simiplify the equation to y=4x+32.
