In triangle ABC, a = 4, b = 6, and cos C = -1/4. What is the length of side c?

Explain why the function is discontinuous at the given number a. (select all that apply.) f(x) = 1 x + 1 a = −1 f(−1) is undefined. lim x→−1+ f(x) and lim x→−1− f(x) exist, but are not equal. lim x→−1 f(x) does not exist. f(−1) and lim x→−1 f(x) exist, but are not equal. none of the above

Which graph represents the linear function below? y-4= (4/3)(x-2)

Vertical angles must check all that apply
