1/3= .3333333
.3333333 x 5= 1.6666666
1.66666+ 7(5)= 1.66666 +35
36.666666
Answer:
j = - 20
Step-by-step explanation:
-2 + j = -22
-2 + 2 + j = -22 + 2
j = - 20
Answer:
C
Step-by-step explanation:
The parabola faces downwards, so "a" will be negative. Using this information, we cancel out answer choice D and A. However in answer choice B, it uses y^2 instead of x^2 which is incorrect. Then, the only option you have left is C which is correct.
Answer:
a. 1620-x^2
b. x=810
c. Maximum value revenue=$656,100
Step-by-step explanation:
(a) Total revenue from sale of x thousand candy bars
P(x)=162 - x/10
Price of a candy bar=p(x)/100 in dollars
1000 candy bars will be sold for
=1000×p(x)/100
=10*p(x)
x thousand candy bars will be
Revenue=price × quantity
=10p(x)*x
=10(162-x/10) * x
=10( 1620-x/10) * x
=1620-x * x
=1620x-x^2
R(x)=1620x-x^2
(b) Value of x that leads to maximum revenue
R(x)=1620x-x^2
R'(x)=1620-2x
If R'(x)=0
Then,
1620-2x=0
1620=2x
Divide both sides by 2
810=x
x=810
(C) find the maximum revenue
R(x)=1620x-x^2
R(810)=1620x-x^2
=1620(810)-810^2
=1,312,200-656,100
=$656,100
