Table Tennis The path of a table-tennis ball after being hit and hitting the surface of the table can be modeled by the function h = - 4.9r * (t - 0.42) where h is the height in meters above the table and is the time in seconds. How long does it take the ball to hit the table? What is the ball's maximum height

$53.50

step-by-step explanation:

you have to subtract the amount of money chuck earned ($72.50) by the cost of the gas for the mower ($11.25) and the new string for the trimmer he bought ($7.75).

72.50-11.25=61.25

and then subtract $61.25 by the second thing he bought (the new string for the trimmer)

61.25-7.75=53.5

so in total it's $53.50 (53 dollars and 50 cents)

answer: 5100 just subtract

step-by-step explanation:
