The value of the car after 5 years would be $23914.85
<u>Explanation:</u>
Given:
Worth of the new car = $50,000
Every 5 years the value depreciates by 1/2
i.e., every 5 years the value depreciates by 50%
So, we can say that every year the value depreciates by 10%
The worth of the car after 7 years would be

where,
W is the depreciated value
C is the current value
D is the depreciation rate
t is the time
Substituting the value in the equation we get:

Therefore, the value of the car after 5 years would be $23914.85
Answer: -4
Step-by-step explanation:
Since lines a and c are parallel and we are given that c is perpendicular to b, we can infer that b is also perpendicular to a.
So, a and b are perpendicular, the angle formed by these lines should be 90.
Hence, angle 2 is 90.
Hope this helps :)
Step-by-step explanation:
Write what you know
mean is: Sum of all data points / Number of data points
any unknown number we'll call x
so youd write
(x + $3191) / 2 = $4444
Solve for x
