A baseball is thrown into the air from a height of 5 feet. The ball reaches a maximum height of 43.5 feet and spends a total of

maks197457 [2]

H = 5 + ut - 16t^2
When the balls falls back to the ground, h = 0
0 = 5 + 3.2u - 16(3.2)^2
0 = 5 + 3.2u - 163.84
0 = 3.2u - 158.84
3.2u = 158.84
u = 158.84/3.2 = 49.6 ft/s

Required equation is
h = 5 + 49.6t - 16t^2

Coordinate plane with quadrilaterals ABCD and EFGH with A at 0 comma 0, B at 2 comma 0, C at 3 comma negative 2, D at negative 1

charle [14.2K]

Answer:

No, quadrilaterals ABCD and EFGH are not similar because their corresponding segments are not proportional

Step-by-step explanation:

Corresponding sides have the same slope, so corresponding angles are congruent.

Side AB is 1/2 the length of side EF; side BC is equal to the length of FG, so corresponding sides are not proportional.

The two quadrilaterals are not similar because their corresponding segments are not proportional (last choice).
