AI Thread Summary
Tom plans to sell birdhouses for $60 each and expects to sell at least 30 per week. If he produces more than 30, he incurs a loss of $2 for each additional house. The proposed revenue function is C(x) = (30 + x)(60 - 2x), where x represents the number of additional houses produced. This setup correctly reflects the total number of houses and the adjusted price per house. The next step is to optimize this revenue function for maximum profit.

Hi everyone - this is my second post on here today!

Anyway, I have a word problem, and would just like to make sure I am setting it up correctly.

Tom expects to sell at least 30 birdhouses a week, at \$60 each. If he produces more than 30, he will lose \$2 per additional house. What is the ideal number of houses to produce?

I have an idea of how to set it up, but just want to make sure it is correct.

I have the equation as: C(x) = (30 + x)(60 - 2x)

Would this be correct to use in this case? The number of total houses to produce would be 30 + x, and the price per house would be 60 - 2x. Is my reasoning correct?

Thanks in advance!

Yes, your revenue function $C(x)$ looks good to me. You have expressed the total revenue as the product of the number of units produced and the revenue per unit. (Yes)

Can you proceed to optimize the revenue function?

Seemingly by some mathematical coincidence, a hexagon of sides 2,2,7,7, 11, and 11 can be inscribed in a circle of radius 7. The other day I saw a math problem on line, which they said came from a Polish Olympiad, where you compute the length x of the 3rd side which is the same as the radius, so that the sides of length 2,x, and 11 are inscribed on the arc of a semi-circle. The law of cosines applied twice gives the answer for x of exactly 7, but the arithmetic is so complex that the...
Is it possible to arrange six pencils such that each one touches the other five? If so, how?

Thread 'Imaginary Pythagoras'
I posted this in the Lame Math thread, but it's got me thinking. Is there any validity to this? Or is it really just a mathematical trick? Naively, I see that i2 + plus 12 does equal zero2. But does this have a meaning? I know one can treat the imaginary number line as just another axis like the reals, but does that mean this does represent a triangle in the complex plane with a hypotenuse of length zero? Ibix offered a rendering of the diagram using what I assume is matrix* notation...
