The answer is a because the graph is slightly curved on the ends and passes the vertical line test
. x² + 20 = 12x ⇔ x² - 12x + 20 = 0<span>
D = b </span> ² <span> - 4 a c = 64</span>,
. x₁, ₂ = (- b <span>±</span> √D <span>) / ( 2a)</span> = ( <span>12 ±</span>√<span> 64) / 2</span> = ( <span>12 ± 8) / 2</span><span> ,
. x</span>₁<span> </span><span> = 10 , x </span> ₂ = 2
(40 seconds) / (2000 rotations) =
(40/2000) (seconds) / (rotation) = 0.02 second per rotation
(3,7) I believe because that coordinate completes the rectangle
