[9.06] jacob kicks a soccer ball off the ground and in the air with an initial velocity of 33 feet per second. using the formula h(t) = −16t2 + vt + s, what is the maximum height the soccer ball reaches?

15.1 feet

16.5 feet

17.0 feet

18.2 feet

C. 17.0 feet

Step-by-step explanation:

We have been given that Jacob kicks a soccer ball off the ground and in the air with an initial velocity of 33 feet per second. We are asked to find the maximum height the soccer ball using formula .

First of all, we will substitute in our given formula.

Since our given parabola has a negative leading coefficient, so it will be downward opening parabola. The maximum height of the ball will be y-coordinate of the vertex of parabola.

Let us find x-coordinate of parabola as:

Now, we will substitute in our formula to find y-coordinate of vertex.

Therefore, the ball reached the maximum height of 17.0 feet and option C is the correct choice.

1

x = 1

step-by-step explanation:

0 ÷ x = 0

0 ÷ 1 = 0

d

step-by-step explanation:

the two points from this line are   (0,4)   & (2,-2)

we can call

now, lets find the slope (m):

now finding b (the y intercept). this is the point at the y-axis where the line cuts the axis. looking at the graph, it is y = 4. so the point is 4. hence b = 4

the slope-intercept form is given by  

putting the points, we have:

d is the correct answer.
