Can anyone help with this question please I’m doing differentiation

mighty cave Mar 17, 2023, 11:03 PM

#

Differentiate the equation then equate the new equation to 0, then solve for t

supple vortex Mar 17, 2023, 11:06 PM

#

Did that

#

Then got the two answers for the quadratic

mighty cave Mar 17, 2023, 11:08 PM

#

What did u get

supple vortex Mar 17, 2023, 11:09 PM

#

T=9.64 or t= 3.61

mighty cave Mar 17, 2023, 11:10 PM

#

So it’s going to be 3.61 as the question asks for the minimum value

supple vortex Mar 17, 2023, 11:11 PM

#

When I sun that into second derivative it says it’s <0

#

So that would be a maximum

#

mighty cave Mar 17, 2023, 11:15 PM

#

Oh shit yeah because the cost is P not t

#

So yeah ur right
