Since ∝ < β you can throw out answers C and D. Using the relationship of sine and cosine being complementary angles you can plug in the two smallest values. Out of those two for 13° you get sin18°=cos72° and 13°+72°=90°, meaning these two angles are complementary.
Answer:
B. Decreasing
Step-by-step explanation:
From the table, we can see that as variable x increases, variable y decreases relatively.
If the data points are plotted on a scatter plot, the trend line would be sloping downwards from our left to our right. This shows that the trend line is decreasing because the sloping downwards from the left to the right shows implies a decrease.
For the first one you have to divide 280 divided by 8 which is 35 the for the 3rd question you have to multiply 35 times 18 which is 630
Sea level is 0. Anything above sea level is positive. Anything below sea level is negative.
And since this one is 400 ft above sea level, then it is 400 (positive)
