Samantha was driving down a road and after 4 hours she had traveled 70 miles. At this speed, how many hours would it take Samant

Readme [11.4K]

Answer:

It would take Samantha 6 hours to drive 105 miles.

Step-by-step explanation:

This question can be solved by proportions.

After 4 hours she had traveled 70 miles.

This means that she travels 70/4 = 17.5 miles per hour.

How many hours would it take Samantha to drive 105 miles?

17.5 miles per hour, so for 105 miles:

105/17.5 = 6

It would take Samantha 6 hours to drive 105 miles.

Need help with math homework

Hello!

The answer for A is:

$X1=-1\\X2=5$

The answer for B is: The rocket will hit the lake surface in 5 seconds.

Defining the terms:

$a=-16\\b=64\\c=80\\$

So, replacing it in the quadratic equation (it's given to you in the exercise)\\

$x=\frac{-b+-\sqrt{b^{2}-4*a*c } }{2*a}$

$x=\frac{-64+-\sqrt{64^{2}-4*-16*80 } }{2*-16}$

$x=\frac{-64+-\sqrt{64^{2}+5120} }{-32}=\frac{-64+-\sqrt{4096+5120} }{-32}\\x=\frac{-64+-\sqrt{9216} }{-32}=\frac{-64+-\ 96 }{-32}\\x=\frac{-64+-\ 96 }{-32}\\x1=\frac{-64+\ 96 }{-32}=\frac{32}{-32} =-1\\\\x1=\frac{-64-\ 96 }{-32}=\frac{-160}{-32} =5\\$

We are working with a quadratic equation, so we will have two possible results,

$X1=-1\\X2=5\\$

Now, we are asked to find the time, time can not be a negative value, we have to discard X1 (-1) since it's a negative value, knowing that, the rocket will hit the lake after 5 seconds.

Have a nice day!
