Polar equations
write the polar eqaution 3 = r cos (theta - 315) in rectangular form.

rational exponents
thank you

rational exponents
express the third root of(8a^3y^5) using rational exponents. Please show your work!

write the equation of the ellipse with foci at (0, -sqrt3) and (0, sqrt 3) and for which 2a=4 i've done this befoe, but with squareroots as endpoints. and if 2a=4, a=2, right? Please help me.

distance formula
Thank you for taking the time to double check my work! God bless!

distance formula
I need to find the distance between two points, (6,-3) and (-1,4). d = sqrt[(x2-x1)^2 + (y2-y1)^2)] I got that down to the sqrt of 98, which is the decimal 9.899494937, approximated at 9.9. Is this the right answer?

Logarithms

Polar equations - Help?
thank you so much, I don't know how i missed that identity.

Polar equations - Help?
i need to graph the polar equation 2 = r cos (theta + 180) on one of the graphs that looks like a flattened globe. So far I have 2=r cos180 costheta + r sin180 sintheta what do i do now?
