Consider the formula for the average velocity, v, of a moving particle. in the formula, d1 and d2 represent the distance traveled by the particle at times t1 and t2 respectively.

Arectangle has a width of 5 cm and a length of 10 cm. if the width is increased by 3, how does the perimeter change?

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.
