Jules kicks a soccer ball off the ground and into the air with an initial velocity of 25 feet per second. Assume the starting height of the ball is 0 feet. Approximately what maximum height does the soccer ball reach? (1 point)

Answers

Answer 1

Answer: Hello,

y=-g/2 t²+25 t is the trajectoire with g=9.81 m/s²

y=-g/2 (t²-25*2/g t)
==>y=-g/2(t²-2*25/g t +25²/g²)+25²/g² * g/2
==>y=-g/2(t-25/g)²+25²/(2g)

==> h=25²/(2g)=625/(2*9.81*3.28084)=9,709479... feet
(for 1m=3.28084 feet)

Write the quadratic equation in general form. (x - 3)^ 2 = 0

Solve the equation for x -x*2-10x+24=0

Answers

Answer:

x=-12 x =2

Step-by-step explanation:

-x^2-10x+24=0

Divide by -1

x^2 +10x -24 = 0

Factor

What 2 terms multiply to -24 and add to 10

12 * -2 = -24

12 -2 = 10

(x+12) ( x-2) = 0

Using the zero product property

x+12 =0 x-2 =0

x=-12 x =2

The answer is x=-12 an x=2

Hello!

As you can see, the angles we are given make up a 90 degree angle. We have the equation below.

4x=90

To solve we just divide both sides by 4.

90/4=22.5
x=22.5

I hope this helps!
