A basketball is dropped from the roof of a building, and its height, in feet, is modeled by the function \(h\).
Here is a graph representing \(h\).
Select all the true statements about this situation.
When \(t=0\), the height is 0 feet.
The basketball falls at a constant speed.
The expression that defines \(h\) is linear.
The expression that defines \(h\) is quadratic.
When \(t=0\), the ball is about 50 feet above the ground.
The basketball lands on the ground about 1.75 seconds after it is dropped.
A group of students are guessing the number of paper clips in a small box.
The guesses and the guessing errors are plotted on a coordinate plane.
What is the actual number of paper clips in the box?
horizontal axis, guess. scale 0 to 32, by 4's. vertical axis, absolute guessing error. scale 0 to 12, by 2's. Points plotted at 14 comma 8, 15 comma 7, 19 comma 3, 21 comma 1, 23 comma 1, 24 comma 2, 26 comma 4, 28 comma 6.
