Answer:
After 7 years it will have a value of $13.946 to the nearest dollar.
Step-by-step explanation:
As it depreciates by 8% (0.08) a year the value of the car after each year is
1 - 0.08 = 0.92 of the previous year's value.
So we have the formula:
Value = 25,000(0.92)^7
= $13,946.17 (answer).
Answer:
3710.67 mm
Step-by-step explanation:
The formula is a^2 h/3
a = 22 h = 23
First, do 22 squared which is 484.
Now do 23 divided by 3 which is 7.666666667
Now multiply 484 and 7.666666667 together to get
3710.666667 or 3710.67 mm
Line 1: y=4x-9
0=4x-9
-4x=-9
x=2,25
Line2: y=-4x+1
0=-4x+1
4x=1
x=0,25
