Find the value of x. If necessary, round your answer to the nearest tenth. O is the center of the circle.
1 answer:
Answer:
x = 9.8
Step-by-step explanation:
(please refer to attached)
after labeling the picture with all the known information, we can see that
OF = OR = Radius of the circle -----(eq 1)
Consider triangle OFP, by Pythagorean theorem,
OF² = PF²+OP²
r² = 11.5² + 11²
r² = 253.25 -----(eq 2)
Consider triangle ORQ, by Pythagorean theorem,
OR² = RQ²+OQ²
r² = 12.5² + x²
r² = 156.25 + x² ----(eq 3)
equating (eq 2) and (eq 3)
253.25 = 156.25 + x²
x² = 253.25 - 156.25
x² = 97
x = √97
x = 9.8 (nearest tenth)

The function and the first value stated for x are confusing.
Doing some research, I found that the problem is to evaluate the function
for x = - 1 and x 2.
The solution is:
1) For x = - 1
2) For x = 2
