Perpendicular means that the slopes are negartive inverses, aka
slope1 times slope2=-1
y=mx+b
slope=m
y=-1/2x-2
slope=-1/2
we need to find negative inverse
-1/2 times what=-1
answer is 2
y=2x+b
input the point (2,-2) to find b
(x,y)
(2,-2)
-2=2(2)+b
-2=4+b
minus 4 from both sides
-6=b
y=2x-6
the equtaion is y=2x-6
By the fundamental theorem of calculus,
So we have
Answer:
400cm^2
Step-by-step explanation
equation: a+b/2 x h
19+25/2 x 20
44/2 x 20
22 x 20
440 (don't forget unit) and to square because we are finding the area
Are you kidding are you sure you want this
