Find the points of intersection of the graphs of the equations. r = 4(1 + sin θ) r = 4(1 − sin θ) r ≥ 0, 0 ≤ θ < 2π

r = 1 + cos θ

r = 1 − sin θ

r ≥ 0, 0 ≤ θ < 2π

(r, θ) = (smallest r-value)

(r, θ) =

(r, θ) = (largest r-value)

- (2, -7)

- lines r and s and lines t and u must be parallel

3,6 and 7.

step-by-step explanation:

a) unit place of 37 is 7

so the unit place of cube of 37 will be

7³= 343=3

the answer is 3.

b) unit place of 56 is 6, so the unit place of cube of 56 will be

6³= 216=6

the answer is 6.

c) unit place of 133 is 3, so the unit place of cube of 133 will be

3³= 27= 7.

the answer is 7.
