Drake jumps from the highest diving board at the American Exhibition wave pool. His height over the pool is modeled by the equation below. h(t) = −4.9t² + 5t + 21 "h" refers to Drake's height above the water in metres. "t" refers to the time elapsed in seconds since Drake makes his jump. How long is Drake in the air before he lands in the water? Paragraph BI UV A 0⁰ + v ... 11.
