Write a statement that indicates that the triangles in each pair are congruent.

Find the cosine function that is represented in the graph.

The area of the map is the product of the length and width. write and expression for the area as the product of the two binomials do not multiply

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.
