Answer:
After 14.92 seconds, the arrow hits the ground.
Step-by-step explanation:
Given:
Initial velocity of the arrow is, ![u=240\ ft/s or 73.152\ m/s](https://tex.z-dn.net/?f=u%3D240%5C%20ft%2Fs%20or%2073.152%5C%20m%2Fs)
The arrow goes up and come back to the same starting position. So, initial position is same as that of final position.
Therefore, displacement of the arrow is 0 m.
The displacement of the arrow is given as:
(equation 1)
Plug all value in equation 1 and solve for ![t](https://tex.z-dn.net/?f=t)
![0=73.152\timests t-\frac{1}{2} \times9.8 \times t^{2}](https://tex.z-dn.net/?f=0%3D73.152%5Ctimests%20t-%5Cfrac%7B1%7D%7B2%7D%20%5Ctimes9.8%20%5Ctimes%20t%5E%7B2%7D)
![0=73.152\timests t-4.9 \times t^{2}](https://tex.z-dn.net/?f=0%3D73.152%5Ctimests%20t-4.9%20%5Ctimes%20t%5E%7B2%7D)
![0=t(73.152-4.9 \times t)](https://tex.z-dn.net/?f=0%3Dt%2873.152-4.9%20%5Ctimes%20t%29)
where ![t\neq 0](https://tex.z-dn.net/?f=t%5Cneq%200)
![4.9\times t=73.152](https://tex.z-dn.net/?f=4.9%5Ctimes%20t%3D73.152)
![t=\frac{73.152}{4.9}= 14.92\ s](https://tex.z-dn.net/?f=t%3D%5Cfrac%7B73.152%7D%7B4.9%7D%3D%2014.92%5C%20s)
∴ After 14.92 seconds, the arrow hits the ground.

Srry If Im wrng but Hope this helped :)
I'm assuming that you meant to add an attachment
but log168 is equal to 2.22530928173
so simply solve the presumed answer choices
The one that equals 2.22530928173 is equivalent to log168
next time please include the attachment

Answer:
23,999
Step-by-step explanation:
Un refrigerador de $8,500.50
Un televisor de $3,500.50
Una computadora de $6,900.00
Una lavadora de $4,999.00
8,500.50 + 3,500.50 + 6,999.00 + 4,999.00 = 23,999.00
