Select all of the following that have the same value as 30,452. A. (3 x 1,000) + (4 x 100) + (5 x 10) + (2 x 1)
O B. (3 x 104) + (4 x 10°) + (5 x 10?) + (2 x 10')
OC. 30.000 + 400 + 50 + 2
D. thirty thousand, four hundred fifty-two
E. (3 x 10') + (4 x 10-) + (5 x 10") + (2 10')
F. thirty-four thousand, fifty-two

d

Step-by-step explanation:

You could just do process of elimination. So for the first one if you add them all up you would get 3,452 which is not correct, for the second one would not be correct since after you do 3 times 104 you can see it is wrong, for c it is also wrong since there is a 30 not a 30,000, for d it is correct since if you write it out is is 30,452, for E it is not correct just by looking at the problem, and for F it cannot be correct since it does not be the right answer

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
