Answer:

m∠A ≈ 39.865°

Step-by-step explanation:

C² = 16² + 15² - 2 × 16 × 15 × cos (97°)

=> C = 23.22708085

sin (97°)/23.22708085 = sin A/15

=> sin A = sin (97°) × 15/23.22708085

=> A = sin^{-1}(sin (97°) × 15/23.22708085)

=> A ≈ 39.865

Which point should be removed for the graph to represent a table of equivalent ratios?
vodomira [7]
<h3>Answer:  D.   (5,15)</h3>

===========================================================

Explanation:

As the graph shows, three of the four points are on the same line. That line being y = 5x. This line has slope 5 and y intercept 0.

The point not fitting this pattern is the point (5,15), so that is the final answer.

For the other three points, note that the jump from x to y coordinate is "times 5". For example, y = 5x = 5*2 = 10 for point A. In contrast, point D has a jump of "times 3" when going from x to y.

--------------

Alternatively, you can divide each y coordinate by its corresponding x coordinate.

  • For choice A, we have y/x = 10/2 = 5
  • Choice B has y/x = 15/3 = 5
  • Choice C has y/x = 20/4 = 5

All results are 5 so far. Choice D doesn't follow the trend and instead has y/x = 15/5 = 3. This is another way to show that choice D is the answer.
