I need some help with Writing Equations of Lines. It's optional if you want to do it step by step but I recommend you do the step by step because I have no idea how to do this.

In the triangles, tr = ge and sr = fe. if = 3.2 ft, which is a possible measure of ? 1.6 ft 3.0 ft 3.2 ft 4.0 ft

The input to the function is x and the output is y. write the function such that x can be a vector (use element-by-element operations). a) use the function to calculate y(-1.5) and y(5). b) use the function to make a plot of the function y(x) for -2 ≤ x ≤ 6.

In the equation sqrt(n+5)-sqrt(11-10)=1. what is the value of n
