A nine digit number that uses one of each of the numbers between 1 and 9. From left to right the number has to be a multiple of 1,2,3,4,5,6,7,8,and 9. For example if the first two numbers were 3 and 6 that would work because 36 is a multiple of 2. So I am trying to find the digit that uses only one of each digit and goes all the way from left to right multiple of 1 to multiple of 9. Good luck and there is only one answer so whoever solves it first is the math expert.

A group of mountain climbers begin an expedition with 265 lb of food. They plan to eat a total of 15 lb of food per day.
A. Write an equation in slope-intercept form relating the remaining food supply R, to the number of days D.
B Graph the equation ( if someone figures out the equation, i'll graph it)
C. The group plans to eat the last of their food the day their expedition ends. Use your graph ( I'll figure one out myself) to find out how many days they expect the expedition to last. How would I figure that out using the graph?? do i like count how high the graph went starting from 0,0??? PLZ HELP!

Have a homework question that I'm having touble solving even question so no correct answer in book. Not to turn in. Class grade is from quiz & exams only.

Water tank shape of inverted circular cone. radius = 5 ft, height = 20 ft, filled to 16 ft with water at a weight of 62.5 lbs/ft3. How much energy to empty tank by forcing water over top of tank.

62.5(pi/16)(20-X)^2 (deltaX)

32ft/s^2(62.5)(pi/16)((20-X)^2... (deltaX)

(125pi)(20-X)^2 (deltaX)

125pi(integral from 4 to 20) 400x-40x^2+x^3

125pi(200X^2-(40X^3/3)+(X^4/4) | 20 to 4

125pi(32768/3) = 4.289 x 10^6 ft lbs

I'm pretty sure this is wrong because example in book is much larger metric tank (r=4m, h=10m, water = 8m, 3.4 x 10^6 J) with a smaller Joule energy requirement. Mabye no one to help but any input is appreciated.
