I’m confused on this one
eduard

The question is asking you to find the measure of YZ's arc.

The arc of a circle is found by finding the central angle. In this case, that's angle YCZ. Remember that a circle's total degrees is 360. Since the angle that you are trying to find is 16% of the circle, you need to find 16% of 360.

360*0.16 = 57.6

The measure of arc YZ is 57.6 degrees.

In how many ways can you select two people from a group of 15 if the order of selection is not important?
Anna35 [415]

Answer:

105 ways

Step-by-step explanation:

Because the order of selection does not matter, we know that we will be using a combination instead of a permutation.

₁₅C₂ = 15! / (2! * 13!)

= 15 * 14 * ... * 2 * 1 / 2 * 1 * 13 * 12 * ... * 2 * 1

= 15 * 14 / 2 * 1 (The 13! cancels out)

= 105

What are the answers and why?
STALIN [3.7K]

Answer:

The selected answers are correct.

Step-by-step explanation:

The first step of the 3-step test for continuity is

  • check to see if the function is defined at the point. Here, the function h(-3) is defined as 5.

The second step of the 3-step test for continuity is

  • check to see if the limit exists at the point. Here, the limit is 2, coming at it either from the left or the right. (log6(36)=2; 16·2^-3=2)

The third step is

  • show the function value is the same as the limit at the point of interest. Here 5 ≠ 2, so there is a discontinuity at x=-3.
