I think what you would do is subtract the "salvage value" of 4,000 from 22,000 to get 18,000. Then since you need the number of years, you would divide 22,000 by the depreciation price of 3,600 to get 5. It would take 5 years for the car's value to reach 4000, therefore she would want to sell it before then.
if you traveled at 40 mph you would go 240 miles in 6 hours. your answer is 40 mph
It's y such that y ≤ 3
{y|y≤3}
Look at the maximum of the values of y (it's 3) now look at the minimum (-infinity) so y is less than or equal to 3.
First, 0.0004853 is < 1, so we need to multiply the number by 10 to a negative power if it's greater than 1 (if that makes sense i cant describe it better)
So, b and c is incorrect.
10 to the power of negative 4 = 0.0001, and 4.853 x 0.0001 = 0.0004853 (true), so answer is a
Answer:
1. L=length W=width
(i dont know 2)
3. area
(let me know if this helps)
