A bouncy ball is thrown into the air. The height of the bouncy ball above ground can be represented by the function h(t)= −16t^2+46t+6, where h is the height (in feet) of the ball above the ground, and t is the time (in seconds) that has passed since the ball was thrown. How many seconds will it take the ball to reach the ground

t=3 seconds

Step-by-step explanation:

h(t)=0 gives

[tex]-16t^2+46t+6=0\\\\8t^2-23t-3=0\\8t^2-24t+t-3=0\\8t(t-3)+1(t-3)=0\\(t-3)(8t+1)=0\\t=3,-\frac{1}{8} (rejected)[/tex]

Jason and Adam are using a kit to build their own electronics board for a computer project. They use a scale drawing included in the instructions to help build the board.

Jason will use the scale factor to find the board's actual length and width, then multiply those dimensions to find the board's area.

Adam says he knows another way.

Answer the questions to show how Adam could find the area of the scale drawing, and then use this strategy to find the area of the electronics board.


1. What is the area of the board shown on the scale drawing? Explain how you found the area.

2. How can Adam use the scale factor to find the area of the actual electronics board? Remember, he uses a different method than Jason.

3. What is the area of the actual electronics board?
