Answer:

A function to represent the height of the ball in terms of its distance from the player's hands is y=\frac{-1}{54}(x-18)^2+12

Step-by-step explanation:

General equation of parabola in vertex form y= a(x-h)^2+k

y represents the height

x represents horizontal distance

(h,k) is the coordinates of vertex of parabola

We are given that The  ball travels to a maximum height of 12 feet when it is a horizontal distance of 18 feet from the player's hands.

So,(h,k)=(18,12)

Substitute the value in equation

y=a(x-18)^2+12  ---1

The ball leaves the player's hands at a height of 6 feet above the ground and the distance at this time is 0

So, y = 6

So,6=a(0-18)^2+12

6=324a+12

-6=324a

\frac{-6}{324}=a

\frac{-1}{54}=a

Substitute the value in 1

So,y=\frac{-1}{54}(x-18)^2+12

Hence a function to represent the height of the ball in terms of its distance from the player's hands is y=\frac{-1}{54}(x-18)^2+12

Solve<br> for x:<br> 3(1 - 3x) = 2(-4x + 7)
djverab [1.8K]

Answer:

x= -11

Step-by-step explanation:

distribute the 3 and the 2:   3 - 9x = -8x + 14

add 9x from both sides and subtract 14 from both sides:  -11 = x

x = -11

5x + 2y = -10<br> 3x + y = 66<br><br> please show work
liq [111]

Answer:

x=142, y=-360. (142, -360).

Step-by-step explanation:

5x+2y=-10

3x+y=66

----------------

5x+2y=-10

-2(3x+y)=-2*66

-----------------------

5x+2y=-10

-6x-2y=-132

-------------------

-x=-142

x=142

3(142)+y=66

426+y=66

y=66-426

y=-360

Caitlin says the difference in their ages is 24 years. In two or more complete sentences, explain whether or not Caitlin is corr
Paraphin [41]

~Hello There!~

\frac{m}{s} =\frac{2}{5}

Rearrange for s

s = \frac{5m}{2}

After 8 years, the new equation would be:

\frac{m+8}{s+8} =\frac{1}{2}

Cross multiply

2m+16 = s+8

Subtract 8

2m+8=s

Substitute old equation

2m+8 = \frac{5m}{2}

Solve to get m as 16.

s = 40.

Their current ages are 16 and 40 and the different is 24 years. Therefore, Caitlin is correct.

Hope This Helps You!

Good Luck :)

Have A Great Day ^_^
