G Prove the Leibniz rule for f ( n ) ( x ) , f(n)(x), where f ( n ) f(n) is the n nth derivative of f ; f; that is, show that ( f g ) ( n ) ( x ) = n ∑ k = 0 ( n k ) f ( k ) ( x ) g ( n − k ) ( x ) .

answer: 204

step-by-step explanation:

we are told that the revenue is

x⋅(4080−10x)=−10x^2+4080x

this is a quadratic function, so to maximize it we should find the x-value of its vertex. recall that the x-value of the vertex of the parabola ax^2+bx+c is given by the formula −b/2a.

so in this case, we have a=−10 and b=4080, so the x-value of the vertex is

−b/2a= −(4080)/2(−10)=204

x= 3^y

step-by-step explanation:

55 degrees because 55+55=110 degrees
