Answer:

  • h = -16t^2 +192t
  • maximum

Step-by-step explanation:

In order to fill in the values in the given function, we need to assume an initial height for the firework. It is convenient to assume that height (h0) is zero. We are given that v0 = 192, so the model is ...

  h = -16t^2 +192t

___

Since the initial upward velocity is well below escape velocity, the firework will eventually fall back to Earth. The height function will have a maximum.

Answer:

\displaystyle h(t) = -16t^2 + 192t; Maximum

Step-by-step explanation:

Maximum Value → Parabola opens downward [<em>−A</em>]

Minimum Value → Parabola opens upward [<em>A</em>]

Andrew uses 630 one-inch unit cubes to completely fill the inside of a rectangular box. Which could be the dimensions of the box
dsp73

we have 630 one-inch unit cubes and we want to completely fill the rectangular box (unknown dimensions).

If all the cubes are fitted tightly inside rectangular box without living any space, then box volume would be equal to cubes volume.

There are 630 one-inch unit cubes, so volume of cubes = 630 cubic inches.

Now the volume of rectangular box would also be 630 cubic inches.

We know the formula for volume of rectangular box = length × width × height.

So we need to find any three positive integers whose product is 630.

Out of all given choices, only option A satisfies the condition of factors of 630.

Hence, option A i.e. (7 in x 9 in x 10 in) is the final answer.

The number of students who picked each subject is shown.
Naddik [55]

Answer: 90% of students did NOT choose history.

Step-by-step explanation:

Art - 32.5%

Spanish - 7.5%

ELA - 10%

Math - 15%

Science - 25%

When added altogether each subject equals 90%, leaving the other 10 percent history. 90% is our answer since that is the number of people that voted for subjects other than history.

Hope This Helped, Have A Great Day!
