A. k/2 B. 2k C. 4k D. 8k E. 16k Given x^2+y^2= K^2 since distance between (0,0) and (x,y)= k distance between (0,0) and (4x,4y) = (4x)^2 + (4y)^2 = 16K^2 hence distance between (0,0) and (4x,4y)= 4k C

A. k/2 B. 2k C. 4k D. 8k E. 16k Using hypotenuse formula, for coordinates (x,y), x^2 + y^2 = k^2 for coordinates (4x,4y), 16x^2 + 16y^2 = 16 (x^2 + y^2) = 16k^2 So the hypotenuse will be 4k

C SQR of x^2 + y^2 = k SQR of (4x)^2 + (4y)^2 = 4 * (SQR of x^2 + y^2) =4k
