the depth underwater,d, in meters, of the dolphin during a dive can be modeled by d=0.1t^2-3.5t+6 where, t is time in seconds after the dolphin begins its its dive underwater how long was the dolphin underwater how deep did it get
+37093 There are multiple ways to solve this....here is a graphical one
@ t=0 the dolphin jumps and grabs air at 6ft above the water ....then dives to a maximum depth 24.6 M at t= 17.5 s
and resurfaces at t= 33.2 seconds
