charle [14.2K]2 years ago
4 0

Answer:

  • A'(4, -4)
  • B'(0, -3)
  • C'(2, -1)
  • D'(3, -2)

Step-by-step explanation:

The coordinate transformation for a 270° clockwise rotation is the same as for a 90° counterclockwise rotation:

  (x, y) ⇒ (-y, x)

The rotated points are ...

  A(-4, -4) ⇒ A'(4, -4)

  B(-3, 0) ⇒ B'(0, -3)

  C(-1, -2) ⇒ C'(2, -1)

  D(-2, -3) ⇒ D'(3, -2)

_____

<em>Additional comment</em>

To derive and/or remember these transformations, it might be useful to consider where a point came from when it ends up on the x- or y-axis.

A point must have come from the -y axis if rotating it 270° CW makes it end up on the +x-axis. A point must have come from the x-axis if rotating it 270° makes it end up on the +y axis. That is why we write ...

  (x, y) ⇒ (-y, x) . . . . . . the new x came from -y; the new y came from x

PLSSSS PSL PLS PLS HELP Theresa Morgan, a chemist, has a 30% hydrochloric acid solution and a 55% hydrochloric acid solution. Ho
igomit [66]

Answer:

165 liters of 15% solution

Step-by-step explanation:

15F + 65S = 60(1650)

F + S = 1650

F = 1650-S

15(1650-S) +65S = 99000

50S = 99000-24750= 74250

S = 74250/50 = 7425/5 = 1485 liters of 65% solution

F = 1650-1485 = 165 liters of 15% solution

65 is much closer to 60 than 15 is,  so you know there will be mostly 65% solution with relatively little 15%

Hope this helps, have a nice day/night! :D
