[ y= a cos (b(-h)) +k ]

In trapezoid abcd, ac is a diagonal and ∠abc≅∠acd. find ac if the lengths of the bases bc and ad are 12m and 27m respectively.

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.

20 ! need ! which exponential function is represented by the table? f(x) = 0.2(0.5x)f(x) = 0.5(5x)f(x) = 0.5(0.2x)f(x) = 0.2(0.2x)
