A car's rear windshield wiper rotates 120°. The total length of the wiper mechanism is 21 inches and the length of the wiper blade is 11 inches. Find the area wiped by the wiper blade. (Round your answer to one decimal place.)

answer: 2530

hope this

y = 3x+4

step-by-step explanation:

to find the slope

slope = (y2-y1)/ (x2-x1)

    = (-8-4)/ (-4-0)

    = -12/-4

  = 3

using the slope intercept form of a line

y= mx+b

we know the slope is 3

we know the y intercept is 4 ( the point where it crosses the y axis or x=0)

y = 3x+4

17,000 is the correct answer.
