A soccer ball is kicked vertically from the ground with an initial velocity of 96 ft/sec.
dmitriy555 [2]

Answer:

h(t) = - 16t² + 96t

Step-by-step explanation:

A soccer ball is kicked vertically from the ground with an initial velocity of 96 ft/sec.

So, it initial height, h_0 = 0 ft. and initial velocity v_0 = 96 feet/sec.

Now, the quadratic function, h(t), that shows the height, in feet, of the soccer ball, t seconds after it was kicked will be given by the general equation

h(t) = - 16t^{2} + v_0t + h_0

⇒ h(t) = - 16t² + 96t + 0

⇒ h(t) = - 16t² + 96t (Answer)

Answer:

Option D will be the correct option.

Step-by-step explanation:

Formula to get the area of the sector,

Area of the sector = \frac{\theta}{360}(\pi r^{2})

Here θ = Angle subtended by the arc of the sector at the center

r = radius of the circle

Area of the shaded sector = \frac{155}{360}\times \pi (4.3)^2

                                            = 25.01 square inches

Area of the shaded sector will be 25 square inches (approximately).

Option D will be the correct option.
