Lesson 5-7 Quiz

(Lesson 5) The expression $16t^2$ represents the distance in feet an object falls after seconds. The object is dropped from a height of 906 feet. What is the height in feet of the object 2 seconds after it is dropped?

• 16
  

• 32

• 874

• 842

(Lesson 5) The expression $16t^2$ represents the distance in feet an object falls after seconds. The object is dropped from a height of 906 feet. Which of the following expressions represent the HEIGHT of the object in feet seconds after it is dropped.
 

•  $h\left(t\right)=906$  

•  $h\left(t\right)=16t^2$  

•  $h\left(t\right)=906+16t^2$  

•  $h\left(t\right)=906-16t^2$  

(Lesson 6) The height, h, of a stomp rocket (propelled by a short blast of air) above the ground after t seconds is given by the equation $h\left(t\right)=5+100t-16t^2$ . Here is a graph that represents h(t). 


What does the 5 in the equation represent in the context?

• How fast the rocket goes.

• Where the rocket starts.

• Gravity.

• When the rocket hits the ground.

(Lesson 6) The height, h, of a stomp rocket (propelled by a short blast of air) above the ground after t seconds is given by the equation $h\left(t\right)=5+100t-16t^2$ . Here is a graph that represents h(t). 


What does the  $-16t^2$  in the equation represent in the context?

• How fast the rocket goes.

• Where the rocket starts.

• Gravity.

• When the rocket hits the ground.

(Lesson 6) The height, h, of a stomp rocket (propelled by a short blast of air) above the ground after t seconds is given by the equation $h\left(t\right)=5+100t-16t^2$ . Here is a graph that represents h(t). 


Approximately when does the rocket hit the ground?

• 5 seconds

• 3.3 seconds

• 100 seconds

• 6.2 seconds

(Lesson 7) This graph represents the revenue in dollars that a company expects if they sell their product for p dollars.

Based on this model, which price would generate more revenue for the company, $5 or $17? Explain how you know.

(Lesson 7) This graph represents the revenue in dollars that a company expects if they sell their product for p dollars.

• Price: $5, Revenue: $3500

• Price: $5000, Revenue: $10

• Price: $10, Revenue $5000

• Price: $20, Revenue: $5000
