A particular power boat travelling at V0 km/h when its power is turned off will have its speed V given by V(t) = V0 × 10^-0.18t where t is the time in seconds since the engine was turned off. The boat was traveling at 50 km/h before powering down. What are the limitations in using this exponential function to describe the speed of the boat?

OpenStudy (anonymous):

V(0)= 50x10^(-0.18x0) = 50 is it correct

OpenStudy (anonymous):

can you tell me what kind of limitations are you giving as answer

None yet

can you "draw" the equation plz

OpenStudy (anonymous):

x= time, and y= speed

OpenStudy (anonymous):

i meant the algebraic equation in the question

OpenStudy (anonymous):

V(t) = V0 × 10^-0.18t

OpenStudy (anonymous):

What do they mean by limitations?
