So you want height to be 0 so you plug zero into the height and solve from there. You subtract 192 from both sides to get -192=-16tsquared. Then you would divide by -16 and end up with 12 = t^2. Then you find the square root of 12 and get t = 3.464 seconds.
Answer:
1/4
Step-by-step explanation:
1st: you need to make a common denominator for 2/3 and 11/12 that would be 12, so you would keep 11/12 how it is but multiply the numerator and the denominator by 4 to get it to 12.
You would have ;
8/12+___=11/12
Then just do 11/12-8/12
so that would simplify out to 1/4
Answer:
![18 \:ft^2](https://tex.z-dn.net/?f=18%20%5C%3Aft%5E2)
Step-by-step explanation:
The area of a trapezoid.
![(a+b)h\frac{1}{2}](https://tex.z-dn.net/?f=%28a%2Bb%29h%5Cfrac%7B1%7D%7B2%7D)
![(8+4)3 \times \frac{1}{2}](https://tex.z-dn.net/?f=%288%2B4%293%20%5Ctimes%20%5Cfrac%7B1%7D%7B2%7D)
![(12)3 \times \frac{1}{2}](https://tex.z-dn.net/?f=%2812%293%20%5Ctimes%20%5Cfrac%7B1%7D%7B2%7D)
![36 \times \frac{1}{2}](https://tex.z-dn.net/?f=36%20%5Ctimes%20%5Cfrac%7B1%7D%7B2%7D)
![=18](https://tex.z-dn.net/?f=%3D18)
12/3 or the same thing as ur question but just add a division sign, eg. difference of two and one that would be 2-1
