Find startfraction partial derivative f over partial derivative x endfraction and startfraction partial derivative f over partial derivative y endfraction for the following function. f(x, y)equalsleft parenthesis 7 x minus 4 y right parenthesis superscript 9 s

ummm seems that u didnt post the attachement !

for this case we have that by definition, the surface area of a cylinder is given by:

where:

r: it is the radius of the cylinder

h: it is the height of the cylinder

we can also rewrite it as:

where:

la: it's the lateral area

ba: area of the base

option a

this is a tricky question, lol,   but i think the answer is 100,000.
