A ball is thrown from the height of 35 meters with an initial downward velocity of 5m/s. The ball's height h (in meters) after t
Verdich [7]
You find this value by factoring.  Factoring finds the zeros of the function.  When the ball hits the ground, it has 0 height.  Therefore, when the function goes through the x axis, it has a y value of 0.  That means that when y = 0, the ball has hit the ground.  Use the quadratic formula to factor h(t)=-5 t^{2}-5t+35.  Notice I rearranged the terms.  When you factor that you get zeros of -3.19 and 2.19.  The two things in math that will never EVER be negative are time and distance/length.  Therefore, that tells us that the ball hits the ground 2.19 seconds after it was thrown.

Answer:

Option A

Step-by-step explanation:

   We know that the "3x ? 2" line must be positive, so it cannot be C or D. The other line is negative, so the "2x ? 5" line must be -2x. This gets rid of option B, leaving us with our answer of A!

Have a nice day!

    I hope this is what you are looking for, but if not - comment! I will edit and update my answer accordingly. (ノ^∇^)
