-3f is the temperature at 9am because -12f is colder than -3f
Answer:
1/3 is the simplified form for given expression.
Step-by-step explanation:
Given that:
=![\sqrt[-3]{27}](https://tex.z-dn.net/?f=%5Csqrt%5B-3%5D%7B27%7D)
By simplifying:
Radical sign will be removed as follows:
= ![27^{-1/3}](https://tex.z-dn.net/?f=27%5E%7B-1%2F3%7D)
For removing the "-" sign from power, base will be inverted:
= ![(1/27) ^ {1/3}](https://tex.z-dn.net/?f=%281%2F27%29%20%5E%20%7B1%2F3%7D)
27 can also be written as 3 * 3 * 3 = 3^3
So,
= ![(1/3^3)^{1/3}](https://tex.z-dn.net/?f=%281%2F3%5E3%29%5E%7B1%2F3%7D)
= ![1^{1/3} / 3^{3* 1/3}](https://tex.z-dn.net/?f=1%5E%7B1%2F3%7D%20%2F%203%5E%7B3%2A%201%2F3%7D)
By simplifying we get:
= 1/3

f (2)=9
Answer:
![6\sqrt{3}](https://tex.z-dn.net/?f=6%5Csqrt%7B3%7D)
Step-by-step explanation:
using the sine rule,
![\frac{sin 60}{x} = \frac{sin 30}{6} \\x=\frac{sin60 * 6 }{sin30} \\x=6\sqrt{3}](https://tex.z-dn.net/?f=%5Cfrac%7Bsin%2060%7D%7Bx%7D%20%3D%20%5Cfrac%7Bsin%2030%7D%7B6%7D%20%5C%5Cx%3D%5Cfrac%7Bsin60%20%2A%206%20%7D%7Bsin30%7D%20%5C%5Cx%3D6%5Csqrt%7B3%7D)
