Write
as an algebraic expression of x that does not involve trigonometric functions.​

i used to know how to do this in 7th but i forget easily

step-by-step explanation:

-4

step-by-step explanation:

do 6-10=

if u need it to be negative.

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

what level of math? also i don't need to be paid if i can you.
