The circumference of a circle can be found using the formula C = 2r. Which is an equivalent equation solved for r? r = C r = C(2) r = r equals StartFraction C Over 2 pi EndFraction. r = r equals StartFraction 2 pi Over C EndFraction.

What is the size of the matrix resulting from

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

20 points 1. your friend, taylor, missed class today and needs some identifying solutions to systems. explain to taylor how to find the solution(s) of any system using its graph. 2. taylor graphs the system below on her graphing calculator and decides that f(x)=g(x) at x=0, x=1, and x=3. provide taylor some feedback that explains which part of her answer is incorrect and why it is incorrect. f(x)=2x+1 g(x)=2x^2+1
