Please someone explain this to me i’m so lost

Problem #2 on the worksheet.

Step-by-step explanation:

So to start this off, draw the line y = -1 on the graph.

That line is going to be the "mirror" of this reflection.

Now each and every point is going to be opposite when it reflects along that line.

Point A = (-2, 5) will reflect and become (-2, -7)

What we did here is just move the point down (because y = -1 is reflecting downwards aka across x-axis). It is located 6 units above the line, so move it 6 units down.

Same with points B and C.

After these transformations, your new triangle will have these points.

Point A-prime: (-2, -7)

Point B-prime: (-2, -3)

Point C-prime: (1, -3)

Hope this helps! :)

  q

step-by-step explanation:

each line from a vertex to the midpoint of the opposite side is called a median. the point where the medians intersect, point q, is the centroid.

the centroid of δabc is point q.

80π/3 or about 83.775

step-by-step explanation:

since a cone is 1/3 of a cylinder, we need to find the base's area. since area = πr^2, we get 16π. then, multiplying this by 5, we get 80π. dividing by 3, since the cone's volume is 1/3 of that of a cylinder's, we get 80π/3.

hope this !
