Evaluate the expression for a = 3 b = 4 c = 6

a³ - ( b + c ) =

✅

Substituting the values of a, b and c in the expression, we have

17 ( See image below:)

Step-by-step explanation:

you substitute what a is which is 3

then b=4

then c=6

so

3^3-(4+6)

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

good luck on ur quiz test or homework. have a good day : )
