I'm so confused by these equations can you please explain them to me?

Rotations Which of the following represents a rotation of A BAT. which has vertices B (-3, -6). A(-2, 11). and T' (10, -4). about the origin by 90"? B(6, 3) A(-11. 2) T(4. -10) B(3. -6) A(2. 11) T(-10. -4) B(3, 6) A(2. -11) T(-10. 4) B(6, -3) A(-11. -2) T(4. 10) 0 / 20 Question 4: 20 pts Which of the following represents a rotation of A LMN. which has vertices L (4, 5). M (0, 2). and N (-2, -4). about the origin by 180* ? L (-5. -4) M(-2, 0) N(4. 2) L(-4. - 5) M(-4. -2) N(2. 4) L(-4, - 5) M(2. 4) N(0. -2) L (-4. - 5) M(0, -2) N(2. 4) 0 / 20 Question 5: 20 pts A water grist mill has a radius of 8ft and takes 6 seconds to make a complete rotation. A bucket starts at position (8, 0). What are the coordinates of the bucket's location after 4 seconds? Round values to the nearest tenth. * Previous
