Determine which of the following is the rectangular form of a complex number.

a) a+bi

b) ab+i

c) abi

d) a-b

x/3-10=8

x/3=18

x=48

- (2, -7)

- lines r and s and lines t and u must be parallel

hello from mrbilldoesmath!

answer:   x^2 + y^2 = 1024

discussion:

the equation of a circle with center (h,k) and radius "r" is

(x-h)^2 + (y-k)^2 = r^2.

in our case

(x-0)^2 + (y-0) ^2 = 32^2 = 1024

you,
