Find Derivative of V(t): We need to find the derivative of V(t) to get the rate of change.V(t)=3000(1−0.05t)2Let's find V′(t), the derivative of V with respect to t.
Apply Chain Rule: Using the chain rule, V′(t)=2×3000(1−0.05t)×−0.05V′(t)=−300×(1−0.05t)
Substitute t=10: Now we substitute t=10 into V′(t) to find the instantaneous rate of change at t=10 minutes.V′(10)=−300×(1−0.05×10)
Simplify Expression: Simplify the expression.V′(10)=−300×(1−0.5)V′(10)=−300×0.5
Calculate Final Value: Calculate the final value. V′(10)=−150
