In APQR, the measure of ZR=90°, the measure of ZP=26°, and PQ = 8.5 feet. Find the length of QR to the nearest tenth of a foot.

i dont get it. where are the "descriptions"?

pi x^2

step-by-step explanation:

pi times x squared

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
