Answer:

3) H' = (-5,-4)    I' = (-2,2)    J' = (-2,-4)

4) K' = (-8,-3)    L' = (-8,-8)    M' = (-6,-8)

5) N' = (2,1)    O' = (1,6)    P' = (-2,3)

6) Q' = (0,3)    R' = (-1,-2)    S' = (3,1)

Step-by-step explanation:

All you have to do is exactly what the directions tell you to do. First, plot the original image of the triangle (The letters without the apostrophe (') behind it), and then recreate it on the opposite side of whatever axis it tells you to. The x-axis is the horizontal line, and the y-axis is the vertical line.

When you're doing this, think of it as a mirror. The mirror is whatever line it tells you to reflect the image across. The final product will be the exact same image, but reversed to the opposite of the axis chosen.

Let me know below in a comment if something confused you in my explanation, I'll try my best to re-word it better so you can understand :)

yuradex [85]
Define i  as a unit vector in the eastern direction.
Define j as a unit vector in the northern direction.

Part I
Because the wind is blowing west, its velocity vector is
 -23i mph or as (-23, 0) mph
Because the plane is traveling north, its velocity vector is
  200j mph or as (0, 200) mph 

Part II
The actual velocity of the plane is the vector sum of the plane and wind velocities.
That is,
200j - 23i or (-23, 200) mph

Part III
The ground speed of the plane is the magnitude of its vector.
The ground speed is
√[200² + (-23)²] = 201.32 mph

The ground speed of the plane is 201.3 mph (nearest tenth)

Not:
The direction of the plane is
 tan⁻¹ 23/200 = 6.56° west of north.

Can someone help me with this. Will mark brainliest. Thank you.
Murljashka [212]

Answers:

  1. circle
  2. center
  3. radius
  4. chord
  5. diameter
  6. secant

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

Explanations:

  1. Consider a campfire and people surrounding it to warm up. The fire itself is the center of the circle, and the people around it are points on the circle's edge. Assume that each person is the same distance away from the fire. Refer to the diagram below.
  2. We always refer to the circle name by the center point. Think of it being like at the center of the universe, or you could think how the sun is at the center of the solar system. While technically the planets orbit in ellipses and not perfect circles, this idea still could be useful to help remember the naming convention.
  3. If we go back to the example in part 1, the radius is the distance from the campfire to any given person. The radius is half the diameter.
  4. This is not to be confused with the spelling "cord" which refers to wiring used in electronics, or in fabric fibers. If we connected any two campers with a segment, then we formed a chord. Refer back to part 1 above. Any diameter is a chord, but not the other way around.
  5. The diameter is a special type of chord that goes through the center. Note the endpoints of the diameter are on the circle's edge.
  6. A secant line is basically a chord but we've extended both endpoints off infinitely in both directions. A secant cuts the circle at 2 different points. In contrast, a tangent line touches the circle at exactly one point only.
