Answer:
The ball will go over the net when she's standing 2 feet away from the net, but not at 4 ft from the net
Explanation:
Suppose then when the player is 2ft from the net, we can plug in x = 2:
As 8 feet > 7 ft 4 in, the ball will go over the net
If the player moves back so that she's 4 feet from the net, plug in x = 4:
As 7 ft < 7 ft 4 in, this time the ball will NOT go over the net
The function models the path of a volleyball when the player is 2 feet from the net and will the ball go over the net at different distances.
The function f(x) = -0.25(x-2)^2 + 8 models the path of a volleyball when the player is 2 feet from the net. To determine if the ball will go over the net, we need to compare the height of the ball's path with the height of the net.
First, let's convert the height of the net to feet. The height, 7 ft 4 in, is equivalent to 7.33 feet. Now, substitute x = 2 into the function to find the height of the ball when the player is 2 feet from the net. f(2) = -0.25(2-2)^2 + 8 = 8 ft.
The ball will go over the net because the height of the ball, 8 feet, is greater than the height of the net, 7.33 feet.
If the player moves back so she is 4 feet from the net, substitute x = 4 into the function: f(4) = -0.25(4-2)^2 + 8 = 10 ft. The ball would still go over the net, as the height of the ball, 10 feet, is greater than the net's height.

Plungingwaves is important to have for a surfer who wants to do aerial maneuvers.
The correct options is A.
When the ocean floor is steep or has abrupt depth changes, crashingwaves occur. They could be large close-outs or strong barrels. Combining pouring and plungingwaves creates a collapsing wave.
When the incoming surf strikes a steep ocean floor or a sea bottom with abrupt depth changes, plungingwaves are created. The wave's peak curves over and erupts on the trough as a result. A crashing sound is frequently audible due to the compression of the airbeneath the wave's lip.

Aerial maneuvers in surfing demand taking the surfboard into the air. The best type of waves for such maneuvers are:
- the section of a wave coming towards you should be smaller than the section you are on
- you should try to find closeout sections of waves ( formations that do not allow a tubular ride )
- the wave should be either wedging or bowling in towards you, it should not be a straight wave.
A.PLUNGING WAVES
B.6.25 times heavier than on Earth
C.2.5 times heavier than on Earth
D.6.25 times lighter than on Earth
Answer: The correct answer is option C.
Explanation:
Weight = Mass × Acceleration
Let the mass of the space probe be m
Acceleration due to gravity on the earth = g
Weight of the space probe on earth = W
Acceleration due to gravity on the Jupiter = g' = 2.5g
Weight of the space probe on earth = W'
The weight of the space probe on the Jupiter will be 2.5 times the weight of the space probe on earth.
Hence, the correct answer is option C.
Answer:
2.5 times heavier than on Earth
