Are
you familiar with that?
------------
amp = 4
and
period=2 pi /4 = pi /2
31) ($6 * 2) + $6.25 + $4.25 + $20 = $42.50
32) $50 - $8.25 - $4.25 -$4.25 - $20 = $13.25
33) 6 * 15.99 = 95.94 | $100 - $95.94 = $4.06
34) $10.50 * 8 = 84 | $100 - $84 = $16
Hope this helps! ^^

Answer:
- JK slope: -1/3
- KL slope: 3
- JL slope: -7
- is
- two of the slopes have a product of -1
Step-by-step explanation:
The slope formula is useful.
m = (y2 -y1)/(x2 -x1)
__
JK slope = (1 -2)/(3 -1) = -1/3
KL slope = (-5-1)/(1-3) = -6/-2 = 3
JL slope = (-5-2)/(1-0) = -7
We observe that slopes (-1/3) and (3) have a product of -1, so those line segments are perpendicular. The triangle is a right triangle.
