W * 10 W = 264
W^2 = 26.4
W = 5.138 L = 51.38 units
10 = 2x^2 -31x + 25 (10 is 10 000 in thousands)
2x^2 -31x +15 = 0 Quadratic formula shows x = 15 months ( 1/2 month also shows as a possible....but unlikely)
Use distance formula to find distance between the two points....this is the diagonal of the square
s^2 + s^2 = diagonal ^2 s= side length
2 s^2 = diagonal ^2
s^2 = diagonal^2 / 2 = area beause (Area = side x side = s^2)
Re-arrange to
x^2 - 7x - 44 = 0
then factor to
(x-11)(x+4) = 0 x = 11 and -4
y = x^2 - 18x - 33 Is a bowl shaped parabola...
the zeroes occur at x = 19.677 ~~ 20 units will produce zero or very minimal profit
Multiplying by a constant will not conver the imaginary number to a real number so
f(1+i) = 2 + 2i
f(2+ 2i) = 4 + 4i
f(4+4i) = 8 + 8i
f(8+8i) = 16 + 16i
Any number that makes a denominator equal to zero (not allowd) will not be in the domain,,,
64 8 and -8 4 sqrt 8 and - sqrt 8
(3 + x)/(5 + x) = (1 - x)/(2 + x) cross multiply to get
6 + 5x + x^2 = 5 -4x - x^2
2x^2 + 9x +1 = 0 Use Quadratic Formula to find x = - 9/4 +- sqrt(73)/4
First position 4 choices ( A M P S)
then 5 digits 10000 choices (00000 through 9999)
4 * 10 000 = 40 000 licenses available
