The train fares are proportional to the square root of distance traveled 2014-01-11 manish pose la question :train fares are proportional to the sq .root of distance traveled. the train fare is Rs. 24.4 for a distance of 140 kms. by how much % does the total fare increase if the same distance is covered by breaking the journey after every 35 kms.Penny Nom lui répond. If 4 cooks can bake 8 pies in 6 hours????? 2013-03-18 Kenneth pose la question :Hello: I want to determine which quantities are directly and inversely proportional in order to determine the answer for the following:. If 4 cooks can bake 8 pies in 6 hours, 2 cooks can bake how many pies in 4 hours? Answer: 2 2/3 pies Can someone fully explain what I need to know in order to determine what is directly and inversely proportional in the example above? I thank you for your reply.Robert Dawson lui répond. If x ix directly proportional to y then ... 2012-02-19 Crystal pose la question :I understand that we say x and y are proportional, then y = kx. Generally when we say x is proportional to y, we think that when x increases y increases. Now I am questioning whether that is actually true. If k is negative, then when x increases, y DECREASES. My question is does this mean this statement is incorrect: If x is proportional to y, when x increases, y increases proportionally. Is it more correct to say: If x is proportional to y, when x increases, y either increases proportionally or decreases proportionally. Along the same line of reasoning, when x is inversely proportional to y, we think that when x increases y decreases, but that is true only if k is positive. Is that correct?Harley Weston lui répond. The derivative of f(x) = (x+1)^1/2 2011-09-05 Carla pose la question :Find the derivative using the limit process of f(x) = (x+1)^1/2Harley Weston lui répond. Using the limit definition 2010-06-06 Meagan pose la question :Using the limit definition find the derivative of 3/(2x^2)Harley Weston lui répond. Direct, inverse and indirect proportionality 2009-03-04 Brian pose la question :My 14 year old is confused about indirectly proportional and inversely proportional. On searching on the internet we were directed to: http://mathcentral.uregina.ca/QQ/database/QQ.09.00/ellis1.html Here leanne starts explaining indirectly proportional and ends up describing inversely proportional. Has Leanne got it wrong ? What is indirectly proportional. Thanks BrianChris Fisher lui répond. y varies jointly as x and the square of z and... 2009-01-05 peter pose la question :I don't really get the terms in this problem. Could you explain it: If y varies jointly as x and the square of z and inversely as the cube of w, by what factor is y increased when z is doubled and w is divided by 3 and x remains the same?Harley Weston lui répond. The derivative of f(x)=1/(x-1) 2007-09-21 Michelle pose la question :im having trouble finding the derivative of f(x)=1/(x-1) using the f(x+h)-f(x)/h method.Stephen La Rocque lui répond. Direct variation 2007-05-07 Jennifer pose la question :assume that y varies directly as x. find y when x = 54 if y =1/4 when x=3/2Stephen La Rocque lui répond. Direct variation 2006-11-05 Johann pose la question :The perimeter of regular octagon varies directly with the length of one side of the octagonStephen La Rocque lui répond.
