Answer:

56% decrease or -56.00%

Step-by-step explanation:

1) Find the difference between 50 and 22 as a number.

2) Divide the result from Step 1 by the starting number 50.

3) Multiply the result from Step 2 by 100 to get it in terms of percent.

The three steps above can be made into a formula. Thus, to find the percent change from 50 to 22, we use this formula:

((Y-X)/X)*100 = Percent Change

X is the starting number 50, and Y is the ending number 22 that it changed to When we enter these numbers into the formula, we get:

((22-50)/50)*100 = -56.00%

After a baseball is hit, the height h (in feet) of the ball above the ground t seconds after it is hit can be approximated by th

lubasha [3.4K]

Answer:

The ball will take 4.05 seconds to hit the ground.

Step-by-step explanation:

we have

$h=-16t^{2}+64t+3$

This is a quadratic equation (vertical parabola) open down

The vertex is a maximum

we know that

The ball hit the ground when h=0

Solve the quadratic equation

For h=0

$-16t^{2}+64t+3=0$

The formula to solve a quadratic equation of the form

$at^{2} +bt+c=0$ is equal to

$t=\frac{-b(+/-)\sqrt{b^{2}-4ac}} {2a}$

in this problem we have

$-16t^{2}+64t+3=0$

$a=-16\\b=64\\c=3$

substitute in the formula

$t=\frac{-64(+/-)\sqrt{64^{2}-4(-16)(3)}} {2(-16)}$

$t=\frac{-64(+/-)\sqrt{4,288}} {-32}$

$t=\frac{64(-)\sqrt{4,288}} {32}=-0.05\ sec$ ---> the time cannot be a negative number

$t=\frac{64(+)\sqrt{4,288}} {32}=4.05\ sec$

therefore

The ball will take 4.05 seconds to hit the ground.

What is the answer to 4(x + 3) < 7x - 3x - 11

diamong [38]

Answer:

THE ANS IS 0<-23

Step-by-step explanation:

4(X+3)< 7x-3x-11

4x+12< 4x-11

4x will be cancelled,

So we get,

4x-4x< -11-12

0 < -23
