The function y=−16x2+v0x models the height of a football in feet x seconds after a player kicks it. In the equation of the funct

ion, v0 is the ball's initial velocity in feet per second. The ball hits the ground 2 seconds after the player kicks it. What is the value of ​ v0 ​?

Answer:

The value of v₀ is 32.

Step-by-step explanation:

The height of a football in feet x seconds after a player kicks it, is defined by the function

y=-16x^2+v_0x

It is given that the ball hits the ground 2 seconds after the player kicks it. The height is 0 at x=2.

0=-16(2)^2+v_0(2)

0=-64+2v_0

64=2v_0

Divide both sides by 2.

32=v_0

Therefore the value of v₀ is 32.

16x^2-vox=0 when x=2 so

16x^2-vox=0

64-2vo

64=2vo

vo=32 ft/s

Solve -2/3x > 8 or -2/3x < 4.

<h3>Answer: Choice C</h3>

{x | x < -12 or x > -6}

=========================================================

Explanation:

Let's solve the first inequality for x.

(-2/3)x > 8

-2x > 8*3

-2x > 24

x < 24/(-2)

x < -12

The inequality sign flips when we divide both sides by a negative value.

Let's do the same for the second inequality.

(-2/3)x < 4

-2x < 4*3

-2x < 12

x > 12/(-2)

x > -6

The conclusion of each section is that x < -12 or x > -6 which points us to <u>choice C</u> as the final answer.

Side note: The intervals x < -12 and x > -6 do not overlap in any way. There's a gap between the two pieces. We consider these intervals to be disjoint. The number line graph is below.
