#

for b and c you need to add the wage of the driver to your initial function too

#

the derivative would be (-1024/x^2)+1

#

,,f'(x)=0.0043165(\frac{-1024}{x^2}+1)

#

and you should solve this for y=0

#

,,\frac{-1024}{x}=-1024x^{-1}

#

to derivate this you need to subtract 1 from the power of x then multiply by the result

#

,,(-1024x^{-2})*(-2)

#

the site makes it way too complicated i suggest you look into videos explaining the power rule simpler

#

,,F(x)=(1.69)(0.0043165)(\frac{1024}{x}+x)+(\frac{510}{x})(15)

#

you should derivate this function and solve for y=0 to find b

#

,,F(x)=(1.69)(0.0043165)(\frac{1024}{x}+x)+(\frac{350}{x})(24)

this for c

wispy hornet Dec 2, 2022, 9:28 AM

#

alright again u should look into the power rule

wispy hornet Dec 3, 2022, 10:33 AM

#

no u cant solve it like that

#

x in this case is not 32

#

you have to derivate that function too and solve for y=0

#

you have to solve all a b and c on their own

distant stratus **yule**

here we calculate the money spent in gas while going x mph and the amount we pay driver while he goes x mph thru the road

#

so essentially you have to find the sweet spot where the sum of those things are minimal

#

x=32 is only minimal for the gas price
