Let's simplify step-by-step.

$Log (5) + (3 log (2)) - \frac{log(4)}{log(10)}$

$= 0.69897 + 3(log (2)) - \frac{log (4)}{log (10)}$

$= 0.69897 + (3) (0.30103) - \frac{log (4)}{log(10)}$

$= 0.69897 + 0.90309 - \frac{log (4)}{log(10)}$

$= 1.60206 - \frac{log(4)}{log(10)}$

$= 1.60206 - \frac{1.60206}{log (10)}$

$= 1.60206 - \frac{1.60206}{1}$

$= 1.60206 - 0.60206$

$= 1$

Llana [10]

18* is 18 above 0. -12* is 12 below 0.
So add: 18+12=X. The difference in temperature is X :)

sattari [20]

Answer:

The scale factor is 2/3.

Step-by-step explanation:

On point M, the point is (-3, 3). The x value, -3 times 2/3 = -2, and the y-value, 3 times 2/3 = 2. Same goes for the rest of the points.
