Answer:
quadrant 4
Step-by-step explanation:
I find it helpful to remember that the cosine is positive in the right half-plane, and the sine is positive in the top half-plane. Knowing the relationship between sine and cosine and all the other trig functions, you can figure their signs in the various quadrants.
The bottom half-plane (sin < 0) and the right half-plane (cos > 0) overlap in the 4th quadrant.
You cut out the question-
Both equations given in the question are the same. So there is no system to solve. It will just be a single line on the graph
There would be a hole when x = -4.
If you factor both the top and the bottom, you will see that the factor (x + 4) is in both the numerator and denominator. Therefore, the would be a hole when x = -4 because that would also make the denominator 0.
235-(-12)=247; his elevation changed by 247 m.
