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:

Answer:
3) 
4) a) 
b) 
Step-by-step explanation:
<u>Exercise 3</u>



<u>Exercise 4</u>
a) If L2 is parallel to L1, it has the same slope (gradient) ⇒ 
If L2 passes through point (3, 1):



So L2 = L1
b) If L3 is perpendicular to L1, then the slope of L3 is the negative reciprocals of the slope of L1 ⇒ 
If L3 passes through point (-5, 2):



If this is supposed to be

Then this can simply be reduced to

by the double angle formula for cosine
