Question

A circle of radius 7 is centered at the point (-8, 9). Find a formula for f(q) (Use the variable q for the angle.)

Answer 1

x^2 + y^2 = r^2

cos^2 + sin^2 = 7^2

49cos(q) + 49sin(q) = 49 ??? hows that

Answer 2

ack!!... forgot to include the off centerd lol

Answer 3

i was sooooo close...

Answer 4

(x+8)^2 +(y-9)^2 = 49

x^2 +16x +64 +y^2 -18y +81 = 49

Answer 5

cos^2(q) + 16cos(q) + sin^2(q) -18sin(q) +96 = 0 maybe??

Answer 6

just to parametrize maybe they are looking for

x= -8+7cos(q)

y= 9+7sin(q)

i don't know if that is what is meant maybe?

Answer 7

hard to tell with the question; I was gonna parametric it, but thought maybe not :)

Answer 8

Thank you that helped
