Use the trigonometric function values of the quadrantal angles to evaluate. 4 cot 270 + 2 sin 90

2

Step-by-step explanation:

4 cot 270° + 2 sin 90°

4 (cos 270°) / (sin 270°) + 2 sin 90°

4 (0) / (-1) + 2 (1)

2

first anwser choice.

step-by-step explanation:

the greater/less or equal to symbol (> or < with the line at the bottom) is a closed/filled in circle.

-5c + 2 _< _27

subtract from both sides by 2

-5c _< _ 27

divide both sides by -5

c _< _ 5.4

flip the inequality sign

c _> _5.4

the only possible answer that would match the simplified inequality is the first answer choice
