A community swimming pool is in the shape of a rhombus. Which statements must also describe the pool? 1a) It is a parallelogram
3b) It is a quadrilateral.

this is not the answer this is just a question. is this middle school math?

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

if the probability is 1/12, 75 people will receive a $25 gift card

step-by-step explanation:

the answer is d
