Answer:

Step-by-step explanation:

The equation $V=-32t+256$ and the graph below describe the velocity V in feet per second of a ball <em>t</em> seconds after it is shot into the air.

To find the balls velocity after seven seconds, substitute t = 7 into the function expression:

$V(7)=-32\cdot 7+256\\ \\=-224+256\\ \\=32\ ft/sec$
