Answers:
a) ![t=\sqrt{\frac{d}{4.9}}](https://tex.z-dn.net/?f=t%3D%5Csqrt%7B%5Cfrac%7Bd%7D%7B4.9%7D%7D)
b) 0.299 s
Step-by-step explanation:
a) We are given the following equation:
![t=\sqrt{\frac{2d}{9.8}}](https://tex.z-dn.net/?f=t%3D%5Csqrt%7B%5Cfrac%7B2d%7D%7B9.8%7D%7D)
If we divide by 2 both the numerator and the denominator, we will have:
![t=\sqrt{\frac{2d/2}{(9.8)/2}}](https://tex.z-dn.net/?f=t%3D%5Csqrt%7B%5Cfrac%7B2d%2F2%7D%7B%289.8%29%2F2%7D%7D)
![t=\sqrt{\frac{d}{4.9}}](https://tex.z-dn.net/?f=t%3D%5Csqrt%7B%5Cfrac%7Bd%7D%7B4.9%7D%7D)
b) From this equation:
![t=\sqrt{\frac{2d}{9.8}}](https://tex.z-dn.net/?f=t%3D%5Csqrt%7B%5Cfrac%7B2d%7D%7B9.8%7D%7D)
is the reaction time in seconds
is the distance
is the acceleration due gravity
Solving:
![t=\sqrt{\frac{2(0.44 m)}{9.8 m/s^{2}}}](https://tex.z-dn.net/?f=t%3D%5Csqrt%7B%5Cfrac%7B2%280.44%20m%29%7D%7B9.8%20m%2Fs%5E%7B2%7D%7D%7D)
This is the reaction time

You have to divide your total by 4 to figure out what 1/4 of the price would be. That makes 1/4 of the price $19,631.15 So really you could just do $78,524.60 x2 to figure out the 2x which is $157,049.20 and then do $19,631.15 x3 to figure out the 3/4 amount which is $58,893.45. Then add the two numbers to get $215, 942.65
X=3 x 4 = 57 is the answer
If you would like to know what was the temperature after the increase, you can calculate this using the following step:
the beginning temperature: -9
increased: 37
the temperature after the increase: -9 + 37 = 28oF
The temperature after the increase was 28oF.
