Read YOUR TURN 4 on the top of page 320 a) Translate all of the information given into symbols and write it here:
(let M = McDonalds, T = Taco Bell, and W = Wendy’s) Do not forget to list n(U).

b) Which region should you fill in first if you wanted to create the Venn Diagram to answer this problem?

c) Draw a Venn Diagram representing the information.

d) How many students ate only at Taco Bell?

-22

times both sides by 2, times () by 8, add alile terms, move terms, add alike and caculate divide both sides by 3

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

step-by-step explanation:

two pairs of adjacent sides are of equal length. this implies that one diagonal divides the kite into congruent triangles, and so the angles between the two pairs of equal sides are equal in measure. it also implies that the diagonals are perpendicular.
