Find the radian measure of the central angle of a circle of radius r that intercepts an arc of length s. RadiusArcLengths 65 kilometers 160 kilometers a, = 4 radians b.32 13 radians 8-4 radians 32 radians 32 radians . 32 d. 13 e. 45

Solution

arc length is given by the formula

s = r theta

theta = s / r

theta = 160 / 65

theta = 32/ 13

option b is correct

2) f(x) = sin 9x

g(x) = 5 + sin 9x

the graph of g is shifted vertically upwards by 5 units

option b is correct
