What is the coefficient of the second term in this expression?
a2c3+a3c+1+ac2

1

Step-by-step explanation:

I assume the term is , and since there is no visible coefficient the coefficient is implied to be 1

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.
