. Substitute C = 50.24 units. Solve for the radius.
Answer:
7
Step-by-step explanation:
Note the relation between x and y
The values of y are 2 less than the corresponding values of x, that is
x = - 3 → y = - 3 - 2 = - 5
x = 0 → y = 0 - 2 = - 2
x = 1 → y = 1 - 2 = - 1
x = 5 → y = 5 - 2 = 3
Thus
x = 9 → y = 9 - 2 = 7 ← missing value
