Select all the lines that have a slope of 5/2.

Answer:

The height of the rock after 3.2 seconds has passed.

Step-by-step explanation:

To respond to this question, we must examine the provided function:

h(t) = –16t2 + 28t + 500

This function h(t) denotes the height of a rock t seconds after it has been launched by a slingshot.

t signifies time (in seconds)

As t is the independent variable and h is the dependent variable, the height of the rock at 3.2 seconds is expressed as h(3.2).

Step-by-step explanation:

The graph can represent a relay race scenario.

Jamie describes a situation that corresponds to the piecewise function illustrated in the graph.

On the graph, the x-axis denotes time in minutes, while the y-axis shows distance in miles.

The initial segment of the graph is a line that extends from the origin to the point (12, 1), with the second segment going from (12, 1) to (20, 2).

1. A runner starts the race and maintains a consistent speed for 1 minute.

• This statement is erroneous as it identifies the incorrect axis.

It should state: a runner initiates the race and runs consistently for 12 minutes, covering 1 mile.

The equation for this segment:

• y = mx + b
• b = 0 since it originates from the starting point.
• m = 1/12
• y = 1/12x
• x = [0, 12], y = [0, 1]

2. Then, his partner takes over and runs faster at a steady pace for another 1 minute.

• Once again, as mentioned earlier, this misrepresents the axis.

It should say: his partner then continues and runs at a constant, quicker pace for an additional 8 minutes, finishing the final mile of the race.

The equation for this segment:

• b = 1, serving as the initial point
• m = (2-1)/(20-12) = 1/8
• y = 1/8x + 1
• x = (12, 20], y = (1, 2]
