John was visiting four cities that form a rectangle on a coordinate grid at A(0, 4), B(4, 1), C(3, -1) and D(-1, 2). If he visited all the cities in order and ended up where he started, what is the distance he traveled? Round your answer to the nearest tenth.

Provide an example of a trigonometric function and describe how it is transformed from the standard trigonometric function f(x) = sin x, f(x) = cos x, or f(x) tan x using key features.

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
