Continued fraction:

[3; 1, 99]

Possible closed forms:

399/100 = 3.99

log(54)≈3.988984

8/(3 π) + π≈3.9904190

1/2 (e! + 1 + e)≈3.989551

-(sqrt(3) - 3) π≈3.983379

(14 π)/11≈3.9983906

25/(2 π)≈3.978873

(81 π)/64≈3.976078

(2 e^2)/(1 + e)≈3.974446

(π π! + 2 + π + π^2)/(3 π)≈3.988765

2 π - log(4) - 3 log(π) + 2 tan^(-1)(π)≈3.987955

2 - 1/(3 π) + (2 π)/3≈3.988291

An individual needs a daily supplement of at least 464 units of vitamin C and 252 of vitamin E and agrees to obtain this supplem
hichkok12 [17]

Answer:

z (min)  = 705

x₁  = 10

x₂  = 9

Step-by-step explanation:

Let´s call  x₁  quantity of food I ( in ou )  and x₂ quantity of food II ( in ou)

          units of vit. C   units of vit.E   Cholesterol by ou

x₁                 32                      9                         48

x₂                16                      18                          25

Objective function z

z  =   48*x₁   +  25*x₂        To minimize

Subject to:

1.-Total units of vit. C at least  464

32*x₁   +  16*x₂     ≥   464

2.- Total units of vit. E at least  252

9*x₁  + 18*x₂   ≥  252

3.- Quantity of ou per day

x₁   +   x₂   ≤  35

General constraints    x₁  ≥ 0    x₂   ≥ 0

Using the on-line simplex method solver (AtoZmaths) and after three iterations the solution is:

z (min)  = 705

x₁  = 10

x₂  = 9

Solve for C when 9=c(c-8)<br><br> Can you show your work too? This question confuses me!
Marrrta [24]
9 = c(c - 8)
9 = c² - 8c
c² - 8c - 9 = 0
c² + c - 9c - 9 = 0
c(c + 1) -9 (c + 1) = 0
(c+1)(c-9) = 0
c = -1 or 9

In short, Your Answers would be -1 and 9

Hope this helps!

The graph below shows a company's profit f(x), in dollars, depending on the price of pens x, in dollars, sold by the company:
Volgvan

The answers to the various part as well as its reasons are given below

<h3 /><h3>Part A:</h3>
  • The x-intercepts shows a zero profit.
  • The maximum value of the graph tells  or depict the maximum profit.
  • The function is one that goes up or increases upward until it reach the vertex and then it falls or decreases after it.
  • This implies that the profit goes up as it reaches the peak at the vertex and it goes down after the vertex up until it gets to zero.
  • The  profits are negative as seen on the left of the first zero and on the right of the second zero.

<h3>Part B:</h3>

An approximate average rate of change of the graph from x = 3 to x = 5, shows the reduction in profit from  3 to 5.

<h3>Part C:</h3>

Based on the above,  the domain is one that is held back or constrained by x = 0 .

We are compelled at x = 6 due to the fact that we have to maneuver a negative profit.
