Answer:
Theta=1.57rad, 4.71rad, 0rad, 2π rad, π rad and –π rad
Ok so find 20% off and see if less tha 75
percent means parts out of 100
20% means 20/100=1/5
'of' means multiply
20% of 80=1/5 times 80=16
off means subtract
disctoun tof 16 is 80-16=64
64<75
how much left over
75-spent=left over
75-64=11
anwwer is $11 left over and enough money to buy
I think it's D. The area of A is k2 times the area of rectangle B
We know that
the slope formula is
m=(y2-y1)/(x2-x1)
(x1,y1)=(0,2)
(x2,y2)=(x,0)
m=1-----> equation 1
m=(0-2)/(x-0)------> m=-2/x -----> equation 2
equate equation 1 and equation 2
1=-2/x------> multiply by x both sides------> x=-2
the point (x2,y2) is ----------> (-2,0)
