Answer:
A. 1922
Step-by-step explanation:
f(x) = 4x + 1 and g(x) = 2x^2
First find f (-8)
f(-8) = 4(-8) + 1 = -32+1 = -31
Then find g(-31)
g(-31) = 2 (-31)^2 =1922
Answer:
The distance from the center of the circle to the longer chord is twice smaller than the distance from the center to the shorter chord.
Step-by-step explanation:
The length of the chord AB is the same as the distance OC from the center to the cord. Let OC=2x, then CA=x. By the Pythagorean theorem, the radius r of the circle is

The length of the arc ED is 4x.
Consider right triangle EFO. In this triangle, EF=2x, EO=r, then the distance OF is

The distance from the center of the circle to the longer chord is twice smaller than the distance from the center to the shorter chord.
