During batting practice, two pop flies are hit from the same location, 2 s apart. The paths are modeled by the equations h = -16

t2 + 56t and h = -16t2 + 156t - 248, where t is the time that has passed since the first ball was hit.
Explain how to find the height at which the balls meet. Then find the height to the nearest tenth.

Sample response: Use substitution to set the equations equal to each other. Solve the resulting linear equation for time, t = 2.48 s. Substitute 2.48 into an equation to find the height, h.

To determine when both balls have the same height, equate the two equations and solve for t.
h = -16t^2 + 56t
h = -16t^2 + 156t - 248
-16t^2 + 56t = -16t^2 + 156t - 248
You can eliminate the -16t^2 terms leading to
56t = 156t - 248
=> 0 = 100t - 248
=> 248 = 100t
=> 2.48 = t
Substituting this t value into either equation will provide the height.
h = 16(2.48)^2 + 56(2.48)
Final response:
h = 40.4736
I hope this assists you:)

tester [12383]
To respond to this inquiry, we must assume that Eva works for 8 hours each day. If that's the case, then on the first day, Eva will complete jobs w, x, and v, amounting to six hours of work. Since job y takes 4 hours, she will only have 2 hours of work that day, leaving her with 2 hours remaining to continue on job y. The following day, she will use those 2 hours to finish job y, completing it, and also work on job z (which takes hours). Consequently, she will have tackled 4 jobs on the first day and 2 jobs on the second, resulting in an average of 3 jobs each day.
This assumption is based on an 8-hour workday and indicates that Eva can initiate jobs she can't finish within the same day.

Lonzell said the function shown in the graph is positive on the interval (−,) and negative on the interval (−,−)open negative 5
Inessa [12570]

Answer:

The segments of the positive graph are located at the coordinates (-5,-4) and (2,5).

In contrast, the negative segment is identified as (-4,2).

Step-by-step explanation:

The positive graph is above the x-axis, while the negative portion lies beneath the y-axis.

Within the interval (-1,5),

The graph appears below the x-axis between (-1,2)

And above it between (2,5).

At this juncture, Lonzell’s assertion is inaccurate.

Within the interval (-5,-1),

The graph again resides below the x-axis in the range (-4,-1)

And above it between (-5,4).

At this point, Lonzell's assessment remains incorrect.

Thus,

The segments of the positive graph are at the coordinates (-5,-4) and (2,5).

Meanwhile, the negative segment is identified at (-4,2).
