The function f(x)=0.04(8x-x^2) where x and f(x) are measured in miles. find the rate of change of elevation at x=2.

so first you will have to substitute 2 in for x. now the equation looks like

f(2)=.04(8(2)-2^2) now u want to do what is in the parenthesis first now the equation looks like:

f(2)=.04(16-4) now do the subtraction and your equation now looks like

f(2)=.04(12) when you do the multiplication you get

f(2)=.48 and that's your answer please rate me brainliest

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

a) 0

step-by-step explanation:

i^413 x i^0 = 0 as any number multiplied by a zero is
