1. How many rotations are needed to go 500 mm with a circumference of 173 mm? 2.How many rotations are needed to go 1528 mm with a circumference of 297.5 mm?

answer:

c) the x-coordinate of the center of the circle increases by 3

thus, the first answer choice, y = sec x, is the correct one

what are the

step-by-step explanation:

assume that you have 3 different side lengths.   apply the pythagorean theorem here:   square each of the two shortest sides; call them a and b, so that their squares are a² and b².   also square the longest side, calling the result c².

now, if a² + b² = c² is true, the triangle is a right triangle; otherwise it is not a right triangle.
