Which equation is equivalent to log 100 = 2? a) 2^10 = 100 b) 10^2 = 100 c) 50×2 = 100 d) 100^2 = 10

Hello!

The inverse of logarithmic function are exponential functions. Remember that if a base of a log is not listed, the base is always 10. Here is how you change log functions to exponential function, or the opposite, exponential functions to log functions:

→ .

The inverse of is .

Therefore, the answer is B, 10^2 = 100.

2^y = ln 5, or   y(ln 2) = ln 5.   solving for y,   y = (ln 5) / (ln 2).   y=5

step-by-step explanation:

whole numbers.

step-by-step explanation:

we are given the average monthly rainfall (in millimeters) model r(m) for the years 1900-2009 as a function of the month number m.

as we can see m is taken for the number of months for years 1900-2009.

we know that number of months can't be a negative number or decimal number or a fraction.

so, the number of months could be only positive whole numbers.

therefore, whole numbers is more appropriate for the domain of r.
