Answer:

option D

Step-by-step explanation:

C (1, 2) is rotated 90° clockwise

When (x,y) is rotated 90 degree clockwise then

(x,y) becomes (y,-x)

Interchange the value of x and y and multiply the x value by negative sign

C (1, 2) becomes (2,-1) that is C'

So ,  C (1, 2) is rotated 90° clockwise is C' (2,-1)

Answer:

D

Step-by-step explanation:

Under a clockwise rotation about the origin of 90°

a point (x, y ) → (y, - x ), thus

C(1, 2 ) → C'(2, - 1 ) → D

adelina 88 [10]

Step-by-step explanation:

Only Q4 has clear details

therefore, solving Question 4,

1 euro = $1.17

then,  €20.46 =20.46×1.17 = $23.93.

1 pound =1.28 dollars.

then,  £12.60 = 12.60×1.28 =$16.128

therefore, MP3 in pound is cheaper in dollar by $7.81.

A biased die has a probability of 1/4 of showing a 5, while the probability of any of 1, 2, 3, 4, or 6 turning up is the same .
just olya [345]
Possibilities of outcomes:
5, 5, 5
5, 5, 4

P(sum at least 14) = P(5,5,4) + P(5,5,5)
= 1/4 x 1/4 x 3/20 + 1/4 x 1/4 x 1/4

Literal Equations: d + 3n = 1, for n
slega [8]
D + 3n = 1        Subtract d from both sides
      3n = 1 - d   Divide both sides by 3
        n = \frac{1 - d}{3}

On a coordinate plane, a parabola opens up. It starts in quadrant 1, crosses the x axis where the vertex is in quadrant 4, and c
andrew-mc [135]
F(x) = (x - 8)2-6

if you simplify the equation you’re left with f(x) = (x - 8) - 4. there are two transformations that can be derived from this equation: translate horizontally right 8 and translate vertically down 4. because the parabola starts in quadrant 1, the parabola needs to be translated right opposed to left to match this. since the parabola’s vertex is in the negative quadrant 4, the function needs to be moved down which matches the second vertical translation the equation gives us.
