Answer:
-27
5
10
-13
Step-by-step explanation:
-9*3=-27 -*+=-
-25/-5=5 -/-=+
7-(-3)=7+3=10 -(-)=+
-2+-11=-13 -+-=-
The basic angle for 1/2 is 60°, and cosines are negative in the first and third quadrant.
So, you take 180° - 60° = 120° to get the angle in the first quadrant, and 180° + 60° = 240° to get the angle in the third quadrant.
Since only 120° is an option, the answer is
B.
Answer:
the quadratic formula is ax^2 + bx + c", if the first one is expanded out I will be 6x^2+8x+27 so that's the answer
