When h=0 is when it returns to the ground
solve

0=32t-16t^2
factor
0=16t(2-t)
set equal to zero

0=16t
0=t

0=2-t
t=2

at t=0 and 2
it returns after 2 seconds

NEED HELP ASAP BRAINLIEST ANSWER IF CORRECT
Alex_Xolod [135]
If we need sections that are 18 ft. long from available 78 ft. long line than we will divide 78/18 =4.(3)
So we will get 4 sections that are 18 ft. long and we will have a remainder of 6 ft line not used.

4 - 3d = d - 8<br> solve for d
torisob [31]
Well you subtract d from both sides with would make 2D-4=-8. Then you subtract four to both sides which is -12. Then you divide -12 by 2D which is 6. D=-6

What is the solution to this equation?<br> x-8=15<br><br> A)x=13<br> B)x=17<br> C)x=7<br> D) x=23
Blababa [14]

Hi there! :)

<u><em>Answer:</em></u>

<u><em>x=23</em></u>

<u><em>*The answer must have a positive sign.*</em></u>

Step-by-step explanation:

This lesson it's about addition property of equality.

First, you add by 8 from both sides of an equation.

x-8+8=15+8

And then, you add by the numbers. Simplify and solve.

15+8=23

Final answer: → x=23

Hope this helps!

Thanks!

-Charlie

Have a great day!

:)

Please help me do the equation and figure out the right solution. I am supposed to be correcting the one in the picture.
alexira [117]

Answer:

The correct answer is if you want no roots in the denominator, the correct answer is \frac{2x}{y}* \sqrt[3]{2y^{2} }

Step-by-step explanation:

The mistake is that you can't take a cube root of a square at step 3 when y^{2} is taken out.
