Answer:
31
51
201
151
Step-by-step explanation:
Addition and subtraction
(r, theta)= (8, 3/2 pi)
r=(x^2 +y^2)^(1/2)
theta= 3/2 pi
x= r(costheta)
y=r(sintheta)
x=8(cos(3/2 pi))
y=8(sin(3/2 pi))
x=8(0)
y=8(-1)
x=0
y=-8
r=((-8)^2+(0)^2)^(1/2)
r=(64+0)^(1/2)
r=8
rectangular coordinates= (0,-8)
Ok,
Do 18 divided by 8 = 2.25
So, $2.25 per pound
Answer: #1 (B: 7/15 #2 (C: 6/18
