Easy points pls help Terri is playing a math card game and has dealt each player four math cards.
Lisa: 2, √2, -5, 1/2
Ben: 0.435435. . ., 0.5, √25, 0
Kari: π, 2, 6, -2
Terri: √200, π, √50, 1.43256744376665. . .

Which person’s hand contains all rational numbers?

Ben

Step-by-step explanation:

We know that pi is not rational  and sqrt(2) is not rational

Ben: 0.435435. . ., 0.5, √25, 0

A repeating decimal can be written as a fraction and sqrt(25) = 5  so Ben has all rational numbers

whats the

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
