Isabell is standing at the top of a waterside that leads to a pool below. the angle of depression from top of the slide to the pool 31.66°, and the slide is 46 feet long. How far is the top of the slide from the ground? round your answer to the nearest foot

reduce the friction between its moving parts

step-by-step explanation:

in fact, by reducing the friction between the moving parts of the machine, it is possible to reduce the energy wasted due to this friction; therefore, more input energy is converted into useful work, and this will improve the efficiency of the machine.

graph b

step-by-step explanation:

one solution- graph a (clear intercepting point.)

no solution- graph b (they're parallel, there will never be a point of interception.)

infinite solutions- graph c (all points intercept.)
