Well, you could say that you want to buy something for $1.25. Like a game or a toy or something! So you need to have $1.25 in order to get this item. You have $50 in your savings account you make 0.75 an hour. And then x would represent the number of hours you have to work. It doesn't really make sense since if you have 50$ in your savings account then you would be able to buy it automatically but, for the sake of this let's just pretend! I'm pretty sure this example will work! Hope it helped!

A ball is thrown into the air with an initial velocity of 22 meters per second. The quadratic function h(x)= -4.9t square +22t+5
MrRa [10]

Answer:

Height of the ball after 3 seconds = 27.4 feet.

Step-by-step explanation:

h(t) = -4.9t^2 + 22t + 5.5

h(3) means the height of the ball at time 3 seconds after the ball was thrown.

h(3) = -4.9(3)^2 + 22(3) + 5.5

=  27.4 feet
