The universal set is the set of all integers. If its subsets A, B and C are given by:
A = {x : x ≤ -1}
B = {. . . , -3, -1, 1, 3, 5, . . .}
C = {x : -5 ≤ x < 4}
Find:
a) A ∪ B
b) A ∩ B
c) C', where C' is the complement of C with respect to ε.
d) A ∩ B ∩ C

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

these are pretty self explanatory if you know what supp right and com angles are

hi i’m going tomorrow morning and i can come over and you out with this stuff for me haha ya day is going crazy and i’ll tell you what i’m talking about you don’t wanna go do you think i’m going to be a good friend i just don’t know how much you mean about the stuff you want to do and stuff you know i just want you and you know that i’m going crazy i don’t think i’m going crazy about going tomorrow and i’ll tell ya hey i don’t think i’m going crazy about going tomorrow and i’ll tell you what i’m done

-1/3(x+1)^5

i’m pretty sure this is correct
