A rock is thrown upwards from a height of 200 feet with an initial velocity of 45 feet/second. The height of the rock above the ground *t* seconds after being released is given by h(t)=- 16^t^2+45^t+200 Make a table of values of *h*(*t*) and match the following:

**Matching pairs**

*h*(0.5)

- Select choice -228.7229.0226.0231.5218.5212.5216.5

*h*(1.0)

- Select choice -228.7229.0226.0231.5218.5212.5216.5

*h*(1.5)

- Select choice -228.7229.0226.0231.5218.5212.5216.5

*h*(2.0)

- Select choice -228.7229.0226.0231.5218.5212.5216.5

*h*(2.5)

To find h(0.5) substitute t=0.5 into the expression for h(t) ie.
