What is the step by step process of solving for the gcf from a list of terms.
ex. (see picture)

Given the equation f(x)=a(b)x where the initial value is 40 and the growth rate is 20% what is f(4)

Acircle has a circumference of 28.36 units what is the diameter of the circle

(b) suppose that consolidated power decides to use a level of significance of α = .05, and suppose a random sample of 100 temperature readings is obtained. if the sample mean of the 100 temperature readings is x⎯⎯ = 60.990, test h0 versus ha and determine whether the power plant should be shut down and the cooling system repaired. perform the hypothesis test by using a critical value and a p-value. assume σ = 5. (round your z to 2 decimal places and p-value to 4 decimal places.)
