Answer:
y=40
Step-by-step explanation:
The formula for Direct Variation is y=kx or k=y/x. In this case I would use k=y/x. If you're y is 8 and x is 3, this means that K=8/3. Using this, we know that X=15. We have to find a Y value so that the fraction with an x of 15 simplified is 8/3. To do this you would write 8/3 and y/15. Now cross multiply to get 3y=120. Divide by 3 to get y=40.

The logarithm of 10 to base 10 is 1
<h3>How to determine the logarithm?</h3>The given parameters are:
Base = 10
Number = 10
So, the expression is:
As a general rule;
The above means that;
When the base and the number are the same, the logarithm is 1
So, we have:
Hence, the logarithmic value is 1
