Answer:
The original temperature was -18°F
Step-by-step explanation:
x°F + 24°F = 6°F
or, x°F = 6°F - 24°F
so, x°F = -18°F
The population of bacteria doubles every 18 hours ( i don’t know if this can help)
The midpoint is calculated by averaging the coordinates of its endpoints:
![M = \left(\dfrac{-2+8}{2},\dfrac{0+2}{2}\right)=(3,1)](https://tex.z-dn.net/?f=M%20%3D%20%5Cleft%28%5Cdfrac%7B-2%2B8%7D%7B2%7D%2C%5Cdfrac%7B0%2B2%7D%7B2%7D%5Cright%29%3D%283%2C1%29)
Now we can use the usual distance formula to get the length of SM:
![SM=\sqrt{(2-3)^2+(8-1)^2}=\sqrt{1+49}=\sqrt{50}](https://tex.z-dn.net/?f=SM%3D%5Csqrt%7B%282-3%29%5E2%2B%288-1%29%5E2%7D%3D%5Csqrt%7B1%2B49%7D%3D%5Csqrt%7B50%7D)
