When you convert 100 feet per second to inches per second, will be there be more or less than 100 inches

We just multiply 100 by 12 to get 1200 inch per second which is more than 100 inches

X^2 - 4x +(4/2^2) + y^2 + 8y + (8/2^2) = -4 + (4/2^2) + (8/2^2)(x + 2)^2 + (y + 4)^2 = -4 + 4 + 16your center is (-2, -4) and the radius is the sqrt of -4 + 4 + 16 which is 4
