Answer:
2.10 s, 10.40 s.
Step-by-step explanation:
We know that the height of the rocket is given by the function:

We are asked to find the time for which the height of the rocket will be 350 ft. So, for that moment, we know the height but we don't know the time; however, we know that the equation can help us to find the time, doing h=350:

The last is a quadratic equation, which can be put in the form
and solved applying the formula:

So, let's put the equation on the form
adding
and subtracting
to each side of the equation; the result is:

So, we note that a=16, b=-200, and c=350.
Then,


According to the equation, that are the times for which the height will be 350 ft; that is because the rocket is going to ascend and then to fail again to the ground.
Answer:
No it doesn't form the triangle because when we sum up two sides the. it should exceed the this side.
The answer is 5/24

Answer: 216.2 miles
Step-by-step explanation:
Alright, lets get started.
As the diagram shows, the line from point P is tangent to earth's curvature.
It means it is making right angle.
So the triangle formed will be right triangle.
Hence we can use Pythagorean theorem in it.
So from point P to center of earth, it will be hypotenuse of triangle.





taking square root, the x will be :

hence the value of x is 216.2 miles. : Answer
Hope it will help :)
