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

ALGEBRA!....
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!

Posted by lauren on Thursday, April 17, 2008 at 8:45pm in response to ALGEBRA. the problem is 92 is greater than or equal to negative 4p. why is the answer p is greater than or equal to negative 23? I am confused! why is it not p is less than or equal to negative 23?

1985 , --- t = 0 1996 , --- t = 11 etc. b) you will have to do the graph, hard to show graphs on here c) set T = 23 23 = (3/5)n + 5 18 = (3/5)n 90 = 3n n= 30 years from 1985 or in 2075

The ground speed is the vector sum of 212 km/h west and 23.6 km/h south. Ground speed = sqrt[(212)^2 + 23.6)^2] = 213.3 km/h Direction = tan^-1(23.6/212) S of W That is 6.35 degrees S of W, or a bearing 263.65 degrees

First evaluate expressions inside parentheses: 5 + 5^2 * 23 + 27 exponents next: 5 + 25 * 23 + 27 Then multiply: 5 + 575 + 27 Now the addition: 607

So since the vapor pressure of water is 23.8 torr p = 0.99 * 23.8 p = 23.6 is this right?

(x-2)5^x - 5^(x+2) = 0 I see a common factor of 5^x 5^x( x-2 + 5^2) = 0 5^x(x + 23) = 0 5^x = 0 or x = -23 but 5^x = 0 has no solution, so x = -23

If I am understanding this picture, a right triangle is formed with angle A = 50 degrees and side b = 23 (15 + 8). You need the length of a, which is the streetlamp. tan A = opp/adj = a/b = a/23 tan 50 = a/23 1.19 = a/23 Solve for a, for your answer

Things are a bit murky, but 2*5^x - x = 23 (2*5)^x - x = 23 are both tough to solve Now, 5^2 - 2 = 23, but that doesn't fit the alleged formula. I suspect a typo

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
