Answer:
3 seconds
Step-by-step explanation:
We want to find t when h=0.
0 = 2t² -5t -3 . . . . . . . divide by -8
0 = (2t +1)(t -3) . . . . . . factor
The values of t that satisfy this equation are the values that make the factors zero: t = -1/2, t = 3. The positive value is the one of interest.
It takes 3 seconds for the object to hit the ground.
Answer and explanation:
<h2>h</h2>
<em>Subtract h + j + 2k = 16 by 4h + 4j + 2k = 5</em>
<em> </em> h + j + 2k = 16
-(4h + 4j + 2k = 5)
-3h - 3j = 11 <em>Then add 3j to both sides to get -3h alone</em>
-3h = 11 + 3j <em>Now divide both sides by -3 to get h</em>
h =
= ![-\frac{11}{3} - j](https://tex.z-dn.net/?f=-%5Cfrac%7B11%7D%7B3%7D%20-%20j)
<h2>j</h2>
<em>Plug in h and k to h + j + 2k = 16 </em>--->
+ j + 2(1) = 16
<em>Then add any like terms together</em>
+ 2j = 16
<em>Add
on both sides</em> 2j =
+ 16
<em>Divide both sides by 2</em> ![\frac{2j}{2} = \frac{\frac{5}{3}}{2}](https://tex.z-dn.net/?f=%5Cfrac%7B2j%7D%7B2%7D%20%3D%20%5Cfrac%7B%5Cfrac%7B5%7D%7B3%7D%7D%7B2%7D)
<em>You can divide a fraction by a fraction, so you do kcf</em> j =
·
= ![\frac{10}{3}](https://tex.z-dn.net/?f=%5Cfrac%7B10%7D%7B3%7D)
<h2>k</h2>
<em>Multiply h + j + 2k = 16 by 2</em> ---> 2h + 2j + 4k = 32
<em>Then subtract 2h + 2j + 4k = 32 by 2h + 2j + k = 31</em>
<em> </em>2h + 2j + 4k = 32
-(2h + 2j + k = 31)
3k = 1 <em>Divide both sides by 3 to get k</em>
k = 1
