in a class of 44 boys 22 boys play football 20 boys play table tennis while 10 boys play neither of the two games. Draw a Venn diagram to illustrate this information. Find the number of boys who play both games ,only football, one of the two games​

use formula for the circle a=3.14

step-by-step explanation:

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
