Afunction is defined by g(a)= -2a+7, and its domain is the set of integers from 1 through 30, inclusive. for how many values of a is g(a) negative

We have

So, for every number greater than 3.5, the function is negative.

In particular, if your domain is the set of integers from 1 to 30, all the integers from 4 to 30, inclusive, will produce a negative result.

circle area = pi * radius^2

if diameter = 10 then radius = 5

circle area = pi * 5^2

circle area = pi * 25

circle area = 78.5398163397 square units
