Answer:
The parametrization, of the given curve is 
Step-by-step explanation:
From the question we are given the function

At y= 5


Converting the above to it polar equation we have

Answer:
one solution
Step-by-step explanation:
3x − 7 = 4 + 6 + 4x
Combine like terms
3x-7=4x+10
Subtract 3x from each side
-7=x+10
Subtract 10 from each side
-17 =x
There is one solution
X2-64=0
x2=64
x=8 because when multiplied by itself, and plugged back in, it works
