Convert the cartesian equation x ^2 + y ^2 - 4x = 0 to a polar equation.
r^2=16/cos2theta
r=-4
r^2=8

step-by-step explanation:

10 - 75

step-by-step explanation:

there's nothing attached so it's most likely anything in that range.

yes

step-by-step explanation:

so of course you want to start by plugging the 5 in which goes to 7(5)+3(5)=50 because 7*5=35 and 3*5=15 and then add them together, then plug in the 5 to the other equation as well 9(5)+5=50 because 9*5= 45 and then add 5 and so yes they are equivalent.
