Vinny worked on her science project for 2 hours and 16 minutes she started at 1:00 how at what time did she finish

For f(x)=2x+3 and g(x)=x^2- 8 find (f+g) (x)

When solving this problem: 3025/5.5 = a/90.75 you get 49912.5 which would be the length of one of the sides of a square when the area is only 90.75 inches. is that answer correct, why, and how is it possible?

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.
