Number of books in non fiction section = 200
Number of books in fiction section = 800
Number of books in reference section = 850
Step-by-step explanation:
Total number of books in the library = 1850
Let us assume, number of books in non fiction section = m
Number of books in fiction section= 4 x Number of books in non fiction
= 4 x (m)
So, the number of books in reference section = 650 + m
Now, Total Number of books = Number of { Fiction + Non- Fiction + Reference} Books
or, 1850 = m + (4 m) + 650 + m
or, 6 m + 650 = 1850
⇒ 6 m = 1850 - 650 = 1200
or, m = 1200 / 6 = 200
⇒ m = 200
Hence, the number of books in non fiction section = 200
Number of books in fiction section = 4 m = 4 x 200 = 800
Number of books in reference section = 650 + m = 200 + 650 = 850
Find a positive number for which the sum of it and its reciprocal is the smallest (least) possible. Let x be the number and let S be the sum of the number and its reciprocal. Write the objective function in terms of x. S(x) nothing The interval of interest of the objective function is nothing. (Simplify your answer. Type your answer in interval notation.) The number is 0.
Answer:
[tex]S(x) = x + \frac{1}{x}[/tex] --- Objective function
Interval = [tex]\{x:x=1\}[/tex]
Step-by-step explanation:
Given
Represent the number with x
The required sum can be represented as:
[tex]x + \frac{1}{x}[/tex]
Hence, the objective function is:
[tex]S(x) = x + \frac{1}{x}[/tex]
To get the the interval, we start by differentiating w.r.t x
Using first principle, this gives:
[tex]S'(x) = 1 - \frac{1}{x^2}[/tex]
Equate S'(x) to 0 in order to solve for x
[tex]0 = 1 - \frac{1}{x^2}[/tex]
Subtract 1 from both sides
[tex]0 -1 = 1 -1 - \frac{1}{x^2}[/tex]
[tex]-1 = - \frac{1}{x^2}[/tex]
Multiply both sides by -1
[tex]1 = \frac{1}{x^2}[/tex]
Cross Multiply
[tex]x^2 * 1 = 1[/tex]
[tex]x^2 = 1[/tex]
Take positive square root of both sides because x is positive
[tex]\sqrt{x^2} = \sqrt{1[/tex]
[tex]x = 1[/tex]
Representing x using interval notation, we have
Interval = [tex]\{x:x=1\}[/tex]
To get the smallest sum, we substitute 1 for x in [tex]S(x) = x + \frac{1}{x}[/tex]
[tex]S(1) = 1 + \frac{1}{1}[/tex]
[tex]S(1) = 1 + 1[/tex]
[tex]S(1) = 2[/tex]
Hence, the smallest sum is 2

What is the greatest common factor, and how is the distributive property used to factor it out from a polynomial?
Answer:
To factor a polynomial, identify the greatest common factor of the monomial terms, and then use the Distributive Property to rewrite the expression. Once a polynomial in a • b + a • c form has been rewritten as a(b + c), where a is the GCF, we say that the polynomial is in factored form.

the ratio of males to females at camp is 5 to 4. if there are 40 males at the camp, how many females are there?
Answer:
32
Step-by-step explanation:
5:4 is the ratio. So 40/5 is 8. Therefore, you must multiply 4 by 8 to get the amount of females at the camp. Ergo, the answer is 32
Answer:
32
Step-by-step explanation:
You can solve this by setting up a proportion.
A 5 to 4 ratio is the same as [tex]\frac{5}{4}[/tex]
The proportion is [tex]\frac{5}{4}[/tex] = [tex]\frac{40}{x}[/tex]
By cross multiplying... you find that x (females) is equal to 32

(2,8),(7,8) slope of the line
Answer:
The slope of line is 0 given points (2,8)(7,8)
Step-by-step explanation:
We need to find slope of line given points (2,8),(7,8)
The formula used to find slope of line is: [tex]Slope=\frac{y_2-y_1}{x_2-x_1}[/tex]
We are given:
[tex]x_1=2, y_1=8, x_2=7 \ and \ y_2=8[/tex]
Finding slope using formula:
[tex]Slope=\frac{y_2-y_1}{x_2-x_1}\\Slope=\frac{8-8}{7-2}\\Slope=\frac{0}{5}\\Slope=0[/tex]
So, the slope of line is 0

Question:
Donatella is planning to mount a television on a wall and wants to make sure it is centered. The wall is 8834 inches in length and she wants to have at least 2412 inches on each side of the television for external speakers. Donatella has researched the lengths of five different televisions.
SELECT ALL of the televisions would fit the remaining space.
Answers Choices:
A. Television A with a length of 3612 inches.
B. Television B with a length of 3814 inches.
Television C with a length of 3934 inches.
C. Television D with a length of 4058 inches.
D. Television E with a length of 4218 inches.
Answer:
Television A, B, and C would all fit.
Step-by-step explanation:
2412 * 2 = 4824
8834 - 4824 = 4010
Therefore, all TVs 4010 inches or less would fit

What is the solution of the system of equations shown above?
Answer:
x = -3
Step-by-step explanation:
First solve it:
Subtract the x's from both sides
2y = -3x +8
2y = -5x +2
Divide by two
y= -1.5x + 4
y = -2.5x +1
set them equal to each other:
-1.5x +4 = -2.5x +1
Add 2.5 x to both sides
1x +4 = 1
x +4 = 1
subtract 4 from both sides
x = -3
