Write a function that matches the description. a cosine function has a maximum of 5 and a minimum value of -5. f (r) =

Three numbers x, y, and z are in the ratio 2: 7: 8. if 12 is subtracted from y, then three numbers form a geometric sequence (in the order x, y–12, z). find x, y, and z. there are 2 sets.

If you prove that ∆wxz is congruent to ∆yzx, which general statement best describes what you have proved?
