Step-by-step explanation:
The function that models Alicia's car is
where x represents the number of years since she purchased the car.
We want to find the value of Alicia's car after 8 years.
We substitute x=8 into the formula to get:
We round to the nearest dollar to get:
The correct answer is C.
About 12.56 units.
Solve for x by plugging in values into Pythagorean theorem.
Simplify
Subtract 144 from both sides
divide both sides by 2
complete the square
take the square root of both sides.
subtract by 6 to get about 17.28 for x.
Plug in values for x to get distance traveled on outside of the yard.
17.28 + (17.28 +12) = 46.56
subtract 34 from the length to get the difference in travel. 46.56-34=12.56
