Determine the value of s, the arc length (measured in inches) cut off in a circle with a radius of 3.4 inches by an angle with a measure of 4.5 radian

Arc length s = 15.3 inches

Step-by-step explanation:

We know that length of an arc that subtends an angle θ radians at the center is given by

where

r is the radius of the circle

θ  is the angle subtended in radians

Thus applying values we get

thus s = 15.3 inches

y = 5x + 17

step-by-step explanation:

a perpendicular line will be the opposite reciprocal slope of the given equation.   the slope given is -1/5 so the opposite reciprocal is 5

find b:

7 = 5 (-2) + b

7 = -10 + b

17 = b

write equation

y = 5x + 17
