For the function given, state the period: f(t)=-100sin (50t-20). a. pi/25 b. 5/2 c.-50pi^2/3 d.50

A

Step-by-step explanation:

period of a sin function is 2π

50 t=2π

t=π/25

period is A

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)
