Who's really good in Calculus??!! reps for fckin life
A manufacture has been selling 1300 television sets a week at 420 dollars each. A market survey indicates that for each 13 dollar rebate offered to a buyer, the number of sets sold will increase by 130 per week.
a) Find the demand function p(x), where x is the number of the television sets sold per week, assuming that p(x) is linear.
b) How large of a rebate should the company offer to a buyer, in order to maximize its revenue?
c) If the weekly cost function is 91000+140x, how should it set the size of the rebate to maximize its profit?
got a lot more questions. mainly the business application ones are fcking me up the azzhole
this one too
The demand for apples is given by the equation xp=200 , where x is the number of pounds demanded and p is the price per pound. If the price is increasing at a rate of 0.25 dollars per week, when the demand is 10 pounds, at what rate is the

Determine the equation of the tangent line at the value x=3 for the function f(x)=6x+10x1.
The slopeintercept form of the equation of the tangent line at the value x=3 is
y= .

nice toes man

a) Find the demand function p(x), where x is the number of the television sets sold per week, assuming that p(x) is linear.
R=P(Q) P=420x, Q=1300+10x
(420x)(1300+10x)= 10x^2+2900x+546000
b) How large of a rebate should the company offer to a buyer, in order to maximize its revenue?
R'=20x+2900=0, x=145, check, 10(145)^2+2900(145)+546000=210250+420500+546000=756250(max rev.)
c) If the weekly cost function is 91000+140x, how should it set the size of the rebate to maximize its profit?
P=RC=(10x^2+2900x+546000)(91000+140x)=10x^2+2760x+455000
P=20x+2760=0, x=138, check, 10(138)^2+2760(138)+455000=190440+380880+455000=645440 (max profit)

a)XP=200, X=10, P=20
P=1.25P, R=XP, R'=12.5, Rev is inc. 12.5% every week
hope this helps

16x1
f'(x)=16
y=3x+16 (i think)

thanks guys. I repped you already but I'll get you again when I recharge

i know its already been answered but heres a pretty obvious tip, googling parts of the question with quotation marks can often help you find the answer you need.
