It is answer C because 59/18 is equal to 3 5/18
Answer: A or C (i think A because its not including)
Step-by-step explanation:
<h2>Hello!</h2>
The answer is:
C. Cosine is negative in Quadrant III
<h2>
Why?</h2>
Let's discard each given option in order to find the correct:
A. Tangent is negative in Quadrant I: It's false, all functions are positive in Quadrant I (0° to 90°).
B. Sine is negative in Quadrant II: It's false, sine is negative in positive in Quadrant II. Sine function is always positive coming from 90° to 180°.
C. Cosine is negative in Quadrant III. It's true, cosine and sine functions are negative in Quadrant III (180° to 270°), meaning that only tangent and cotangent functions will be positive in Quadrant III.
D. Sine is positive in Quadrant IV: It's false, sine is negative in Quadrant IV. Only cosine and secant functions are positive in Quadrant IV (270° to 360°)
Have a nice day!
-1/9+-5/9=
When you are adding a negative number, the operation turns into subtraction:
-1/9-5/9=
Really, it's just subtraction. The simplest form is -2/3, which is equal to -0.66667.
I hope this helps :)
