Question 37

The rate at which a submersible drone consumes battery power, P(t)P(t)P(t) in watts, is modeled by the function:

P(t)=20t3−65t4+92 P(t) = 20t^3 - \frac{6}{5t^4} + \frac{9}{2} P(t)=20t3−5t46​+29​

where t>0t > 0t>0 is the duration of the mission in hours. Find an expression for the total energy consumption by evaluating the indefinite integral:

∫(20t3−65t4+92)dt \int \left( 20t^3 - \frac{6}{5t^4} + \frac{9}{2} \right) dt ∫(20t3−5t46​+29​)dt

giving each term in its simplest form.
