A ball is launched upward from a height 40 feet above ground level. The ball’s height at t seconds is given by -16t^2=128=40 .

Nesterboy [21]

Answer:

The ball will be at 100 feet at time x=0.5 sec and at time x=7.5 sec

Step-by-step explanation:

The correct question is

A ball is launched upward from a height 40 feet above ground level. the ball's height at t seconds is given by h(t)=-16t^2+128t+40 At what time(s) will the ball be at 100 feet?

we have

$h(t)=-16t^{2}+128t+40$

For h(t)=100 ft

substitute in the equation and solve for x

$-16t^{2}+128t+40=100$

$-16t^{2}+128t-60=0$

The formula to solve a quadratic equation of the form

$ax^{2} +bx+c=0$

is equal to

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

in this problem we have

$-16t^{2}+128t-60=0$

$a=-16\\b=128\\c=-60$

substitute in the formula

$x=\frac{-128(+/-)\sqrt{128^{2}-4(-16)(-60)}} {2(-16)}$

$x=\frac{-128(+/-)\sqrt{12,544}} {-32}$

$x=\frac{-128(+/-)112} {-32}$

$x=\frac{-128(+)112} {-32}=0.5$

$x=\frac{-128(-)112} {-32}=7.5$

therefore

The ball will be at 100 feet at time x=0.5 sec and at time x=7.5 sec

The number of bacteria in a culture is expected to grow 82% per hour over the next several hours. The predicted change in the nu

Advocard [28]

If my simplification is valid the answer is:

1.4 % growth each minute

I don’t feel like the representation
P = 120(1.82) is important in this certain problem.

So P the predicted number of bacteria is not practical with this problem.

Use the 82% per hour and divide it by 60 because there are 60 minutes in an hour.

When doing this you find the rate in which bacteria grows which is about 1.4%.

The prediction is about 1.82 percent for 120 something it’s not clarified, but I’m guessing that’s minutes.

So you can prove that the prediction is over the rate in which bacteria grows per minute.

You subtract 8 from 13=5
Now you are finding the perimeter.
13+7+8+9+5+15=58
58 cm.
Wish you happy timez!
