The education is (x-h)^2 + k ands the vertex is (h,k)
Radius = OC = OD
Solve for x:
10x -16 = 6x+2
4x = 18
x = 9/2 = 4.5
Sub 'x' back into OC
OC = 6(4.5) + 2 = 29
Radius = 29
Answer:
Groot
Step-by-step explanation:
Let the average cost of car in 2009 be $x, then the average cost of a car in 2013 is 2x - 5
25,000 = 2x - 5
2x = 25,000 + 5 = 25,005
x = 25,005/2 = $12,502.50
|-5| is equivalent to 5, since that is how far -5 is from 0.
So, the question is simplified to: How far away is -5 from 5?
We get 5-(-5)=10.
Remember, absolute value is always positive (expect for 0) and the distance between two numbers is always positive (expect for 0).
