Model rocket is launched from a raised platform at a speed of 176 feet per second. Its height in feet is given by h(t)=-16t^2+17

6t+20 (t=seconds after launch)
What is the maximum height reached by the rocket? and what time does it meet maximum height?

<span><span>The first step is to find the vertex. You do this by using the formula </span>\frac{-b}{2a}. 
<span>
Plug in b and a into the equation: </span>\frac{-176}{2(-16)}
<span>
You get </span>5.5<span>

So, it takes 5.5 seconds to get to 504 feet

Hi, apply the formula:

Xv = - b / 2a

Where,

b = 176
a = -16
c = 20

Then, the value of Xv will be:

Xv = - (176 / 2 .-16)

Xv = 176 / 32

Xv = 5,5 s

So , just us will go to make the substitute of Xv in equation.
And we will go to find the value of H

H(t) = Yv

As , Yv = h(Xv)

H(t) = -16t^2 + 176t +20

Yv = - 16.(5,5)^2 + 176.(5,5)+20

Yv = -484 + 968 + 20

Yv = 504 feet

This would be the answer to the your question.

Hope this helps

Which of the following is the estimated amount of salt that will dissolve at 47 degrees?
Nina [5.8K]

Ths solubility curve can be used to obtain the amount of salt dissolved (solubility).

<h3>What is the solubility curve?</h3>

The solubility curve is a plot of the solubility of a substance against the temperature. It serves the purpose of being used to show the solubility of a susbtance at different temperatures. This question is incomplete hence we can not be able to deduce the solubility of the salt at this temperature.

If the solubility curve has been ploted, then we can be able to estimate the solubility of the salt from the graph.

Answer:

All real numbers

Step-by-step explanation:

4(x+1) = 4x+4

Distribute

4x+4 = 4x+4

Subtract 4x from each side

4x+4-4x = 4x+4-4x

4=4

This is always true so there are infinite solutions

Using the number line, determine which expressions have a value that is greater than –8. Select Yes or No for each expression. l
Nimfa-mama [501]
<h3>Answer:</h3>

yes

  • -6-(-6)
  • -4-(-7)

no

  • all others
<h3>Step-by-step explanation:</h3>

Doing what the directions say is generally a good idea.

Adding a number moves to the right; subtracting a number moves to the left. Subtracting a negative number is the same as adding its opposite.

The arrowhead end of the line in the figure is the end result. Two of them end up to the right of -8, that is, greater than -8.
