The height of a ball thrown straight up in the air is described using the equation h=12gt2+v0t+h0, where h=height
t=timeinseconds
g=accelerationduetogravity
v0=initialvelocity
h0=initialheight
The initial height is 2 meters above the ground, the initial velocity is 12.25 m/s2, and acceleration is the force of gravity near the Earth's surface, which is −9.8 m/s2.

(Acceleration is negative because it is downward relative to height.)

What is the tallest height the ball could reach?

Enter your answer as a number, rounded to the nearest tenth, with the appropriate unit, like this: 4.2 m

Hint: The highest or lowest point on any parabola (graph of a quadratic equation) is its vertex.

Lab 1: central tendency and standard deviation directions: use excel to compute descriptive statistics. problem: you are the manger of a fast food store. part of your job is to report to the boss at the end of each day which special is selling best. use your knowledge of descriptive statistics and write one paragraph to let the boss know what happened today. here are the data. use excel to compute important values (mean, median, mode, and standard deviation). make sure to include a copy of your work. this should be submitted via canvas (no exceptions). make sure you include your excel work in addition to a summary of the results. special number sold cost huge burger 20 $2.95 baby burger 18 $1.49 chicken littles 25 $3.50 porker burger 19 $2.95 yummy burger 17 $1.99 coney dog 20 $1.99 total specials sold 119
