The first equation in the system models the heights in feet, h, of a falling baseball as a function of time, t. The second equat
Masja [62]

Answer:

The height of the baseball is 35 feet at the moment the player begins to leap.

Step-by-step explanation:

We are given equations as:

h(t)=35+16t^2--------(1)

Where h represents the heights in feet, h, of a falling baseball as a function of time, t.

The second equation is given as:

h(t)=6+18t-16t^2-------(2)

Where h represents  the heights in feet, h, of the glove of a player leaping up to catch the ball as a function of time, t.

Hence when at the time of leap i.e. at t=0.

first equation i.e. equation (1) yields h(0)=35 i.e. it represents:

"  The height of the baseball is 35 feet at the moment the player begins to leap "

Hence option: C is correct.
