The demand equation is a linear equation and it defines the algebraic representation of quantity and price of product. The form of equation of linear function is the following, such that: `P(x) = a*x + b` The price point elasticity of demand can be evaluated using derivative of demand function Q, with respect to price P, such that: Point Price Elasticity of Demand = `(Delta Q)/(Delta P)` Given `Q(x) = 600 - 3P(x) + 0.04I - 2P(z)` and...http://www.enotes.com/homework-help/please-help-suppose-we-have-following-hypothetical-479797Thu, 21 May 2015 18:13:41 PSTGiven 12-(2x+1)=1+2xlet (2x+1) = (1+2x)=yso 12-y=y=> 12=2y=>...

Since 3 men and 3 women needs to be part of delegation, and since selection is from 5 men and 3 women....it implies that all the women would always be part of the delegation. Since either youngest woman or youngest man can be in delegation, and since all women are in delegation; the youngest man will never be a part of the delegation. That leaves the selection of 3 men from a set of 4 men and this can be done in 4 ways. So, there are only 4...http://www.enotes.com/homework-help/dear-educator-please-help-me-find-solution-this-479838Thu, 21 May 2015 15:24:44 PSTdear Educator please help me find solution for this math problem ; here...

dear Educator please help me find solution for this math problem ; here it is : a delegation consisting of 3 men and 3 women, chosen from the set of 5 men and 3 women of different ages who are different ages. The delegation may include at most only one of the youngest members of the woman or of the youngest members of the men.

please check your question again. There seems to be some error with your equation. You can check by using any set of values of A, B and C. I tried with (60,60,60) and (90,45,45). Use the fact that A+B+C = pi and hence pi-A = B+C, etc.http://www.enotes.com/homework-help/delta-abc-prove-that-sin-2-sin-b-2-sin-c-2-1-4cos-479824#5Thu, 21 May 2015 06:34:43 PSTIn `Delta` ABC Prove that : sin (A/2) + sin (B/2) + sin (C/2) = 1 +...

So I will solve some problems from each question, so that you can follow the lead and complete the assignment. 1. `(-2-2sqrt3 i)^3 = (-2)^3 (1+sqrt3 i)^3 = 8 [(1+sqrt3 i) (1+sqrt3 i)^2] ` `= 8[(1+sqrt3 i) (1+2sqrt3 i -3)] = 8[(1+sqrt3 i)(2sqrt3 i -2)] ` `= (8)(2)(sqrt3 i +1)(sqrt3i-1) = 16(-3-1) =16 xx-4 = -64` We have...http://www.enotes.com/homework-help/can-someone-please-hepl-me-with-rest-problems-pre-479788Thu, 21 May 2015 00:46:44 PSTSuppose we have the following hypothetical demand function: Qx = 600 -...

Suppose we have the following hypothetical demand function: Qx = 600 - 3px + 0.04I - 2pz Where Px = $ 70, Pz = 68, I = $ 24,000 (disposable income per capita). What is the demand equation? The price of product X, Px = 70. Calculate the price point elasticity of demand.http://www.enotes.com/homework-help/please-help-suppose-we-have-following-hypothetical-479797#7May 20, 2015, 9:55 pm PSTCan someone please hepl me with the rest of the problems in pre cal
