The predicted depth of the dive is 68.16 feet
Since the equation given is y=5.1+10.51t, then, in order to get the predicted depth of the dive, we've to put the value of t = 6 seconds into the equation and this will be:
y = 5.1+10.51t
y = 5.1 + 10.51(6)
y = 5.1 + 63.06
y = 68.16 feet
Therefore, the predicted depth of the dive is 68.16 feet.
