The table shows the height in feet, h, of a hot air balloon and the number of minutes, t, the balloon is in the air. The equation y = 30.5t + 8.7 can be used to model the data table. Explain the meaning of the slope and y-intercept in context.

The slope (30.5) represents the rate of change of the height of the balloon every minute, and the y-intercept (8.7) is the initial height of the balloon.

The slope (8.7) represents the rate of change of the height of the balloon every minute, and the y-intercept (30.5) is the initial height of the balloon.

Alan has been saving for a new video game. He currently has some money saved in his savings account. Each week, he earns additional money mowing his neighbor’s lawn. Use the equation, y = 20x + 85, to explain the meaning of the slope and y-intercept in context.

The slope (20) represents the amount of money Alan earns each week mowing the lawn, and the y-intercept (85) represents the initial amount of money he already has saved.

The slope (20) represents the amount of money Alan spends each week on video games, and the y-intercept (85) represents the cost of the video game.

The slope (20) represents the number of video games Alan can buy each week, and the y-intercept (85) represents the total number of video games he wants to buy.

The slope (20) represents the number of weeks Alan has been saving, and the y-intercept (85) represents the total amount of money he has earned.

A rental car charges a flat rate of 100 dollars plus $5 per mile driven. The cost can be represented by the equation c(x) = 5x + 100. Explain what the statement c(30) = 250 means in the context of this scenario.

If the car is driven for 30 miles, the total cost of the rental will be $250.

If the car is driven for 250 miles, the total cost of the rental will be $30.

D: { x | 0 < x < 36} R: { y | 0 < y < 3}

D: { y | 0 < y < 36} R: { x | 0 < x < 3}

What is the domain and range of the graph?

D: { x | 0 < x < 28 } R: { y | 0 < y < 9 }

D: { y | 0 < y < 28 } R: { x | 0 < x < 9 }

A ball is thrown in the air from a platform that is 48 feet. The height of the ball, in feet, can be represented by the function h(t) = –16t 2 + 32t + 48, where t is the time, in seconds, since the ball was thrown. Identify the vertex of the function and explain what it represents in context.

(1, 64); this means the ball will reach a maximum height of 64 feet after 1 second.

(0, 48); ; this means the ball will reach a maximum height of 48 feet after 0 seconds.

(3, 16); this means the ball will reach a maximum height of 16 feet after 3 seconds.

(2, 32); this means the ball will reach a maximum height of 32 feet after 2 seconds.

A marine biologist is studying dolphins and sharks. The function d(x) = -x 2 + 6x can be used to represent the pathway of a dolphin’s jump out of the water. The function s(x) is represented in the graph and can be used to represent the pathway of a shark’s jump out of the water. Did the dolphin or the shark have a higher jump?

Both had the same jumping height.
