A tennis ball is launched from the ground and follows a parabolic path represented by the equation y = - x ^ 2 + 8x , where x=sec seconds. At the same time, an arrow is shot from a height of 20 feet and follows a straight path represented by the equation y = - 3x + 20 U sing your graphing calculator , when will the arrow pierce the tennis ball and at what height off of the ground ? y represents the height of the ball

The dinosaurs ribs and arm are the solution of given equation..

For solving the equation we have,

y=0.5x + 3.5

y= –0.75x + 37.25

A/Q

Now,putting the value of x....find the value of y..

y=0.5x+3.5

=>y=0.5(27)+3.5

=>y=17

thus,x=27

y=17

So,no. of dinasaur ribs=x=27

No. of dinasaur arms=y=17
