The graph represents the height y, in meters, above the ground of a golf ball x seconds after it is hit. which statements are true? select each correct answer. for up to 5.5 s after the golf ball is hit, its height is increasing. it takes 11 s for the golf ball to fall to the ground after reaching its maximum height. the golf ball is in the air for 11 s. the maximum height of the golf ball is 150 m. the golf ball's speed is 11 m/s .

For up to 5.5 s after the golf ball is hit, its height is increasing

The golf ball is in the air for 11 s

The maximum height of the golf ball is 150 m.

Step-by-step explanation:

we know that

The graph shown a vertical parabola open downward

The vertex is a maximum

The vertex is the point (5.5,150) ---> that means

For t=5.5 s, the height of a golf ball is h=150 m

Verify each statement

case A) For up to 5.5 s after the golf ball is hit, its height is increasing.

The statement is true

For the interval (0,5.5) > the height is increasing

For the interval (5.5,11) > the height is decreasing

case B) It takes 11 s for the golf ball to fall to the ground after reaching its maximum height

The statement is false

It takes 5.5 s for the golf ball to fall to the ground after reaching its maximum height

case C) The golf ball is in the air for 11 s

The statement is true

For t=11 s the golf ball fall to the ground (h=0)

case D) The maximum height of the golf ball is 150 m.

The statement is true

The maximum height of the golf ball is at the vertex of the parabola

The vertex is the point (5.5,150)

case E) The golf ball's speed is 11 m/s

The statement is false

a) one student is chosen from classroom a, then a student is chosen from classroom b.  

step-by-step explanation:

independent events are ones in which the probability of one event does not affect the probability of the second event.

one student is chosen from classroom a; this does not affect the chances of choosing a student from classroom b.   this makes these independent events.

when one card is chosen from a standard deck and then set aside before a second card is chosen, the probability of the second card being chosen changes.   this makes them dependent events.

when one student is chosen from classroom a and then a second student is chosen from classroom a, the probability of choosing the second student changes.   this makes them dependent events.

when a letter is chosen from the alphabet and then a second letter is chosen, the probability of choosing the second letter changes.   this makes them dependent events.

the answer is (-4,-4)

hope this ! : d
