Skeet shooting is a competitive event where participants shoot clay targets that have been mechanically flung into the air. During an Olympic trial, the height of the skeet can be modeled by the equation, h(t) = −5t² + 32t + 2, where h is the height in meters t seconds after the skeet is released. If the path of the bullet can be modeled by the function, h(t) = 31.5t + 1 with the same units for height and time. Answer the questions that follow. The bullet will hit the skeet at When the skeet is hit, it will be seconds. feet off the ground.

The total number of people, in thousands, age 65 years old and over who were below the poverty level can be modeled by N(t) = -59(t- 12) + 3890 where N(t) represents the total number of people 65 years old and over in the United States who were below the poverty level, in thousands, t years since 1980.1 (a) How many people 65 years old and over were below the poverty level in 2000? In 2000 there were people 65 years old and over below the poverty level. (b) When were there 1 million people 65 years old and over below the poverty level? (Hint: 1 million = 1000 thousand) According to this model, there were 1 million people 65 years old and over below the poverty level in the years (smaller value) and (larger value). (c) What is the vertex of this model, and what does it represent? In about there were people 65 years old and over below the poverty level. This was the maximum number of people around this time.
