The equation y=−3.5x2−0.5x+65 models the height of a ball in inches for each bounce. note it's 3.5x to the second power. what is the best approximate for the height of the ball after the 3rd bounce? 7 in. 14 in. 32 in. 50 in.

Given equation is y = -3.5x-0.5x+65

y represents the height of the ball and x represents the number of bounces.

After 3rd bounce, so plug in x= 3 in the given equation, we get

Y=-3.5(3)-0.5(3) + 65

y = - 3.5 (9) - 0.5(3) + 65

y = - 31.5 - 1.5 + 65

y = -31.5 - 1.5 +65

Y = - 33 + 65

y = 32

So best approximate height of the ball after 3rd bounce is 32 in.

answer: the sun

explanation:

water cycle describes the evaporation of water from earth's surface, formation of clouds and precipitation water back onto the surface of earth. seventy percent of the earth is covered with water in the form of seas and oceans. the heat of the sun causes the evaporation of water from the surface of the ocean. the water vapors rise and condense to form water droplets. the collection of these water droplets form clouds which rain down again.

the evaporation of the oceans surface water as part of the water cycle is caused by the sun
