Hi...I am taking pre calculus and I'm reallyo lost here..can someone help me?

1. What is the logarithm form of each equation?
1.49 = 72
2.216 = 63
3.256 = 28
4.64 = 43
5.3125 = 55

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.

the arc length is found by finding the circumference of the full circle (2xpixradius) and then dividing by 4 to find just one quarter of the circle (90 degrees).
