Answer:

Step-by-step explanation:
meants when
, that the value for
is 5.
So this gives us this equation:

meants when
, that the value for
is 10.
So this gives us this equation:

So I take equation 2 and divide it be equation 1 I get:

Simplifying:

Since the base for an exponential function can't be negative then
.
So plugging into one of my equations I began with gives me an equation to solve for the initial value,
:


Divide both sides by 2:

The function is:

Formula:
2 B + P x H
Answer: 12 gallons
Step-by-step explanation:
The car uses 16 gallons to travel 240 miles. You need to calculate how many miles is in a gallon. So, divide 240 by 16 (you get 15). That is 15 miles per gallon. Next, you divide 180 by 15 to calculate how many gallons it would take you to travel 180 miles if there are 15 miles in a gallon.
This is in the lower right corner and is a right triangle. So we use the Area calculation of a right triangle.
<u>ab</u> = <u>(4)(2)</u> The height is given as 4 in and we know the base is 2 in
2 2 We know this because the top right distance is given as 2
8 / 2 = 4 square inches
