Answer:

(0,4) \implies (-4, 0)\\(3,5) \implies (-5,3)\\(2,-1) \implies (1,2)

Step-by-step explanation:

A 90° counterclockwise rotation is defined as

(x,y) \implies (-y,x)

The given coordinates are

(0,4)\\(3,5)\\(2,-1)

Applying the 90° counterclockwise rotation, we have

(0,4) \implies (-4, 0)\\(3,5) \implies (-5,3)\\(2,-1) \implies (1,2)

The image attached show both figures.

Delicious77 [7]

Step-by-step explanation:

Sin^2 (x) * Cos^2 (x) = {[1 - cos (2x)]/2}*{[1 + cos (2x)]/2}

Sin^2 (x) * Cos^2 (x) =[ 1 - cos^2 (2x)]/4

Sin^2 (x) * Cos^2 (x) = (1/4) - (1/4) * cos^2 (2x)

Sin^2 (x) * Cos^2 (x) =  (1/4) - (1/4) * {[1 + cos (2*2x)]/2}

Sin^2 (x) * Cos^2 (x) =  (1/4) - (1/8) * [1 + cos (4x)]

Sin^2 (x) * Cos^2 (x) =  (1/4) - (1/8) - (1/8)* [cos (4x)]

Sin^2 (x) * Cos^2 (x) =  (1/8) - (1/8)* [cos (4x)]

Replace F in the equation with 113.

5/9(113-32)

5/9(81)

5 * 81 = 405
405 / 9 = 45 degrees Celcius

C=48y+0.99n solve for y
Ne4ueva [31]

Answer:

  y = (C -0.99n)/48

Step-by-step explanation:

Undo what is done to y, in the reverse order. We have y multiplied by 48 then added to 0.99n. So, we must add the opposite of 0.99n and multiply that result by the reciprocal of 48.

  C = 48y + 0.99n . . . . . . given

  C - 0.99n = 48y . . . . . . add -0.99n

  (C -0.99n)/48 = y . . . . . multiply by 1/48
