It's angles 9 and 10.
Supplementary angles are two angles that add up to 180°.
So, supplementary angles both "stick" off of a straight line. (Because a straight line is 180°).
Answer is 4 I think so yeah
Given:
Initial value of new car = $17,500
Depreciation rate = 4.6%
To find:
The value of car after 4 years.
Solution:
The exponential decay model is

where, a is initial value, r is decreasing rate and t is time in years.
Substitute a=17500, r=0.046 and t=4 in the above equation.





The value of car after 4 years is $14495.44.
Therefore, the correct option is D.
