Answer:
r = 5sec(θ)
Step-by-step explanation:
The usual conversion is ...
y = r·sin(θ)
x = r·cos(θ)
__
The second of these can be used here.
r·cos(θ) -5 = 0
r·cos(θ) = 5
r = 5/cos(θ) = 5sec(θ)
A suitable polar equation is ...
a
Answer: f(x) = 500(2)^x
Fraction: 5/6
(1/2) / (3/5) = 1/2 X 5/3 = 0.83333333333
