Landon plans to throw a penny from the roof of a building. The building is 102 feet tall, and Landon throws the penny with an initial upwards velocity of 10.4 feet per second. The penny hit the ground approximately 2.87 seconds later. Select the appropriate definition and domain for the variable x for the equation that models the height of the penny, H. Then, select the correct equation. A. Select a definition of the variable x .
x is the number of seconds since Landon threw the penny.
x is the height of the penny in feet.
x is the number of seconds since the penny hit the ground.
B. Select the domain that best fits the situation.
0 ≤ x ≤ 2.87
x ≥ 0
all real numbers
C. Select the equation that can be used to model the height of the penny.
H = - 16 x 2 + 104 x + 102
H = - 16 x 2 + 102 x + 10.4
H = - 16 x 2 + 10.4 x + 102
