Question

Tolong jawab nomor 24 aja pake cara. Terima kasih kak.​

Answer 1

Penjelasan dengan langkah-langkah:

A (-3, -2)

B (6, -2)

C (6, 12)

a] Rotasi [0, 90°]

P(x, y) → P'(-y, x)

A (-3, -2) → A'(- (-2), -3)

A (-3, -2) → A' (2, -3)

B (6, -2) → B'(- (-2), 6))

B (6, -2) → B' (2, 6)

C (6, 12) →C'(-12, 6)

b] Dilatasi [0, 3]

P (x, y) → P' (k . x, k . y)

A (-3, -2) → A' (3 . -3, 3 . -2)

A (-3, -2) → A' (-9, -6)

B (6, -2) → B' (3 . 6, 3 . -2)

B (6, -2) → B' (18, -6)

C (6, 12) → C' (3 . 6, 3 . 12)

C (6, 12) → C' (18, 36)

C] Refleksi terhadap sumbu x

P (x, y) → P'(x, -y)

A (-3, -2) → A' (-3, - (-2))

A (-3, -2) → A' (-3, 2)

B (6, -2) → B' (6, - (-2))

B (6, -2) → B' (6, 2)

C (6, 12) → C' (6, -12)
