 Some non-decreasing sequences 2015-04-13 Sky pose la question :Hi I'm a Student and i'll try my best to state the problem perfectly. The number of non-decreasing sequences of size at least 1 and at most N, such that each element of the sequence lies between L and R, both inclusive. Eg:- N=1 L=4 R=5 ans= 2. [{4},{5}] N=3 L=4 R=6 ans= 19. [{4},{5},{6},{4,4},{4,5},{4,6},{5,5},{5,6},{6,6} {4,4,4},{4,4,5},{4,4,6},{4,5,5},{4,5,6},{4,6,6},{5,5,5},{5,5,6},{5,6,6} ,{6,6,6}]Claude Tardif lui répond. A sequence or a series? 2013-09-05 Rahul pose la question :Whether the following sequence is increasing or decreasing? I even do not kow whether to call it a sequence or not. an = (1/(1+n))+(1/(2+n))+....+(1/(n+n)). I am confused. It looks like a series to me. Please help. Regards, RahulRobert Dawson lui répond. Decreasing numbers 2011-04-13 Hadi pose la question :A number is called a "decreasing number" if each digit in the number is less than the digit to its left. For example, 87420 is a deceasing number. How many five-digit decreasing numbers are there?Claude Tardif lui répond. A curve sketch 2007-11-22 Ahson pose la question :Find critical points, determine the monotonicity and concavity and sketch a graph of f(x) with any local maximum, local minimum and inflection points labeled: 1. f(x) = x^4 - x^3 - 3x^2 + 1Harley Weston lui répond. Increasing and decreasing for functions 2007-11-09 David pose la question :Direction: Identify the open intervals on which the function is increasing or decreasing. f(x)=1/(x^2) f'(x)= -2/(x^3) i understand how to get up until there, and the undf. is x=0, but now i'm having problem setting up the number table chart. i cant remember how, and where to place the increase and decrease + - the chart, for example <---------0----------> where would the increase and the decrease be place?Harley Weston lui répond. f(x) = (x^4) - 4x^3 2007-07-22 Michael pose la question :I'm a student who needs your help. I hope you'll be able to answer my question. Here it is: Given the function f(x)=(x^4)-4x^3, determine the intervals over which the function is increasing, decreasing or constant. Find all zeros of f(x) and indicate any relative minimum and maximum values of the function. Any help would be appreciated. Thank you for your time.Harley Weston lui répond. 8-digits numbers with their digits in decreasing order 2006-05-09 Headmaster pose la question :How many 8-digits number are there with their digits in decreasing orderPenny Nom lui répond.
