The thread length of a screw is the part of the screw with threads. The function t(x) = |x – 63.75| can be used to find the difference, in millimeters, of a specific screw’s thread length, x, and the expected value. If a screw’s thread has a radius of 35.5 millimeters, the volume of the difference in thread can be calculated by the function V(t) = 1,260.25πt. Which function can be used to find the volume of the difference in thread length depending on the total thread length?

c. y = 1/4 x + 5

step-by-step explanation:

first, put the equation of the line on the graph into slope-intercept form

(y = mx + b):   y = -4x + 8

second, a perpendicular line has to have "an opposite/reciprocal slope" to the original slope. so, find the "m" value in your original equation (it's -4, right? )

original slope: m = -4   perpendicular slope: change the sign to its opposite and find the reciprocal ("flip" the number)

new slope is now positive (b/c the original slope was negative 4), and it's 1/4 (not the original slope of 4 or 4/1)

3

step-by-step explanation:

divide 13.5 by 9 to get the scale factor. it equals 1.5

2 * 1.5 = 3
