Answer:
a = 13
Step-by-step explanation:
Isolate the variables by dividing each side factors that do not contain the variable.
The coefficient of the first term.
If it's talking about the left end, then it'll be the first degree. So since it's to the third power, you'll have something that looks like x^3, which starts at the bottom left. The negative sign indicates a swapped axis. So it'll be the coefficient (which is -3). That states it'll start from the top left and go downward. The +3 is just a vertical shift.
Answer: C) 0
You can use a calculator to get this answer, a reference table, or the unit circle. The angle pi radians is equivalent to 180 degrees. Note how the point on the unit circle corresponding to 180 degrees is (1,0). This point has a y coordinate of zero. More broadly, y = sin(theta) where theta is the angle.
