0=2x-1 x=1/2, y=1/4-1/2-23=-23.75 That is with Calculus. Now in Algebra, do this y=x^2-x + xxxx -23-xxxxx we are going to make a difference of prefect squares. y=x^2-x+1/4 -23-1/4 y= (x-1/2)^2 - (sqrt22.75)^2 so clearly, this is a minumum at x=1/2

Got it! Initial population is 23^2, which = 529. 23^2 + 48 = 577 = 576 + 1, so 23^2 + 48 = 24^2 + 1, and 23^2 + 96 = 625, so 23^2 = 25^2 Did it by exhaustion with Excel. Check back later if I can do it algebraicly!

A. x = 5 f ( 5 ) = 2 * 5 + 3.50 = 10 + 3.50 = 13.50 $ B. x = 3 / 4 f ( 3 / 4 ) = 2 * 3 / 4 + 3.50 = 6 / 4 + 3.50 = 6 / 4 + 7 / 2 = 6 / 4 + 14 / 4 = 20 / 4 = 5 $ C. f ( x ) = 50 50 = 2 x + 3.5 50 - 3. 5 = 2 x 46 . 5 = 2 x Divide both sides by 2 46.5 / 2 = x 23.25 = x x = 23.25 ...

so sub l= (23/w) into l+w = 32 23/w + w = 32 23 + w^2 = 32w w^2 - 32w + 23 = 0 solve for w, then plug into l=23/w I got w = .7357 l = 31.2643 check: .7357x31.2643 = 23.001 .7357 + 31.2643 = 32
