1. The graphs of two trigonometric functions, f(t) = 4 cos(0 - 90°) and g(z) = 2 cos(0 - 90°) +1, are shown below. The function g() is subtracted from the function f(x) to get a new function A(). What is the minimum value of A(z)?

step-by-step explanation:

15

step-by-step explanation:

we are given the following expression and we are to solve it and find the product:

-13 × (-5)

solving the given expression in the standard order of solving a mathematical expression, beginning with the opening of brackets and then multiplying the terms and changing their signs.

-3 × -5 = 15 (answer is positive because when negative is multiplied with negative, it gives a positive answer)
