Answer:
C. log 10m is the correct answer.
Step-by-step explanation:
The laws of logarithm states that if you have:
![log(a) + log(b ) = log(a \times b) = log(ab)](https://tex.z-dn.net/?f=%20log%28a%29%20%20%2B%20%20log%28b%20%29%20%20%3D%20%20log%28a%20%5Ctimes%20b%29%20%20%3D%20%20log%28ab%29%20)
So, comparing that to your question,
![log(m) + log(10) = log(10m) .](https://tex.z-dn.net/?f=%20log%28m%29%20%20%2B%20%20log%2810%29%20%20%3D%20%20log%2810m%29%20.)
The temperature rose so you add the amount it rose to the starting temperature
68.7 + 9 = 77.7 degrees
It then dropped so mow you subtract t the amount it dropped:
77.7 - 12.3 = 65.4 degrees
The answer is 65.4 degrees
Answer:
m = 18/4 = 9/2 = 4.5
Step-by-step explanation:
Notice that the line passes through (0, 0) and (4, 18). Thus, its 'rise' is 18 - 0, or 18, and its 'run' is 4 - 0, or 4, and the slope (which is the desired constant of proportionality) is m = 18/4 = 9/2 = 4.5 This is Answer B
