Answer:
k = log9 / log 0.66
k = 5.3
Step-by-step explanation:
Please always remember that, when an exponential equation is given with different bases, the best approach is to take log of both sides.
If you have a calculator handy, that would be pretty fast and easy.
0.66 ^ k = 9
Take log of both sides:
klog 0.66 = log 9
k = log 9 / log 0.66
k = 0.954 / - 0.18
k = -5.3

Answer:
27.8 Celsius
Step-by-step explanation:
The equation to convert Fahrenheit and Celsius is:
F = (9/5)C + 32
82 = (9/5)C + 32 -- subtract 32 from both sides
50 = (9/5)C -- multiply both sides by 5
250 = 9C -- divide by 9
27.777 = C
round up to 27.8 C
