A windowpane is 9 inches by 12 inches. What is the distance between opposite corners of the windowpane?

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,

mrb

step-by-step explanation:

a'(12.5,11.25)

slope=(y1-y2)/(x1-x2)
