Naya [18.7K]

Answer:

B.) 4,096 feet

Step-by-step explanation:

You were given a time, and time in the equation is represented by "t". To find the height, represented by "h", you just need to plug the given value in for "t" and simplify to find "h".

t = (1/4)√x                                         <--- Original equation

16 = (1/4)√x                                      <--- Plug 16 in "t"

64 = √x                                            <--- Divide both sides by (1/4)

4,096 ft = x                                    <--- Square both sides

How do you find f(2x) when you know f(x) = x^3?
babymother [125]
To find the answer, you just plug 2x in place of x (even though 2x already has an x). It would look something like this: f(2x)= (2x)^3 = 2x*2x*2x= 8x^3

7x + 2y = 17<br>2x - 2y = 1<br>=​
DerKrebs [107]

Answer:

(2,\frac{3}{2}})

Step-by-step explanation:

For finding the system of equations you can use one of two methods. There's the elimination method and also the substitution method. For this I think the best way we could go at solving this is by using the elimination method. Since we can eliminate the 2y. We can then solve for x and then we'll go from there.

\left \{ +{{7x+2y=17} \atop {2x-2y=1}} \right. \\\\9x=18\\x=2

Now that we know what x is we can substitute it for one of the equations and then we will be able to solve for y.

7x+2y=17\\7(2)+2y=17\\14+2y=17\\2y=3\\y=\frac{3}{2}

So now we have the x and the y and once we place them together we can get the solution of those two equations, and the solution is (2,\frac{3}{2}}).
