The sanctuary currently has 125 exotic fish. The average amount of the tank allotted for each fish is represented by the binomial (22−1). Are the dimensions of the new habitat adequate for these 125 fish? Explain.

it is contrapositive

i could not see the question too well so check yourself again too . this is because i want you to get it correct.

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
