Answer:
Tim's percent error is 58.1 % .
Step-by-step explanation:
Formula
Where
Change in value = |Approx value - original value|
As given
Tim predicts he will get 98 points on the next exam.
If Tim actually earned 62 points .
Original value = 62
Approx value = 98
Change in value = |98 - 62|
= 36
Putting all the values in the formula
Percentage error = 58.1 % (Approx)
Therefore Tim's percent error is 58.1 % .

Answer:
C: (-8,3) R:5
Step-by-step explanation:
The equation of a circle can be written as:
(x-h)^2+(y-k)^2=r^2
where (h,k) is the center, and r is the radius
We have the equation:
(x+8)^2+(y-3)^2=25
Center:
The center is (-8,3)
(x+8)^2--> (x-h)^2
Therefore the x coordinate of the center is -8
(y-3)^2-->(y-k)^2
Therefore the y coordinate of the center is 3
Radius
r^2=25
Take the square root of both sides
r=5
