Sale tax of 3 binders is closest to the david total purchase.
As per the given question
Binders=3Pen=5
Reams=2
Binder cost $3.50 each
Pen cost $1.15 each
Paper cost $4.00 each
Tax =7.75%
Let's solve it
3 binder =3×$3.50=10.5
5 pen = 5×$1.15=5.75
2 reams =2×4.00=8
Total cost before tax = 10.5+5.75+8=24.25
Total sale tax =24.25×7.75%=1.879375
Total purchase after sale tax =24.25+1.879375=26.129375
As we calculate 3 binder=10.5
This is the closest to it.

If you see marginal cost increasing in a graph, this implies that
a. marginal product must be increasing, too.
b. the additional cost incurred in producing one more unit of output is decreasing.
c. the company is experiencing some inefficiency in production.
d. the productivity of the company is increasing.
If you see marginal cost increasing in a graph, this implies that; b. the additional cost incurred in producing one more unit of output is decreasing.
What is the interpretation of the marginal cost?
The marginal cost is the change in total production cost that comes from making or producing one additional unit.
When marginal product is rising, the marginal cost of producing another unit of output is declining and when marginal product is falling marginal cost is rising. Thus, Option A and D are not correct.
Option C is wrong because Marginal cost helps to increase efficiency in production.
Thus, option B is the correct answer.

ab=4x+17 ad=96+2x find bc
By subtraction of functions, the length of the line segment BC is equal to 79 - 2 · x units.
How to use the subtraction of functions
In this question we find to two line segments that are collinear to each other. Each line is represented by a linear functions, whose length equations are:
AB = 4 · x + 17 (1)
AC = 96 + 2 · x (2)
AB + BC = AC
BC = AC - AB (3)
Then, by (1) and (2) on (3):
BC = (96 + 2 · x) - (4 · x + 17)
BC = 79 - 2 · x
By subtraction of functions, the length of the line segment BC is equal to 79 - 2 · x units.
Remark
After a quick investigation, we conclude that the statement has typing mistakes, correct form is shown below:
If AB = 4 · x + 17 and AC = 96 + 2 · x, then find the expression of BC.

select Function 4 and use the Range and Domain sliders to identify the range and domain. Complete parts 1 and 2 below. Use the interactive figure to find your answer. Use the left and right arrow keys to move along a slider as needed. Click here to launch the interactive figure.
Answer:
Domain: (-∞, 2] U (3, 6]
Range: (-∞ , 1] U (-1, 4]
Step-by-step explanation:
This is a piecewise function. It has a discontinuity at x=2 and x = 3
The domain of a piecewise function is the union of the domains of each piece of the function. Similarly the range for a piecewise function is the union of the ranges for each piece of the function
Looking at the graph, we can see two subdomains. When x ≤ 2 , we have one subdomain and when x > 3 there is another subdomain. We state this as
D = - ∞ < x ≤ 2 or 3 < x ≤ 6
In interval notation we represent this as
D = (-∞, 2] U (3, 6]
The nature of the brackets is important a [ or ] bracket means that the value to which it is attached is included whereas an open bracket, ( or ) means that value is not included
For example, (-∞, 2] means that everything below x = 2 to -∞ is part of the domain but it does not include -∞; since at -∞, a function is not defined. However it does include 2 in the domain as can be seen by the closed bracket on the right
The other subdomain is for x > 3 (note: a filled circle means the value is included, an empty circle denotes the value is excluded)
The second subdomain is
3 < x ≤ 6
In interval notation, it is (3, 6]
So the total domain is the union of the two intervals
The range is also discontinuous and there are two distinct ranges. The range is nothing but all the set of values generated by the function. So we look at all possible values for y that the function produces
The Range of this function is -∞ < f(x) ≤ 1 or -1 < f(x) ≤ -4
In interval notation this is
R = (-∞ , 1] U (-1, 4]

Use this graph of function f.
For how many values of x is f not differentiable over the interval (–4, 4)?
Answer:
4
Step-by-step explanation:
In the graph of the function, between the interval (-4, 4), there are 4 values of x for which the given function is not differentiable.
The method of determining the derivative of an implicit function by differentiating each term separately, expressing the derivative of the dependent variable as a symbol, and solving the resulting expression for the symbol.
here,
The function from observation seems to be a discontinuous function,
And the function is not differentiable at x = -1, 0, 1, and 3.
So there are 4 points in the interval (-4, 4) where the function is not differentiable.
Thus, In the graph of the function, between the interval (-4, 4), there are 4 values of x for which the given function is not differentiable.

Paula pays $19.92 for 2.4 pounds of walnuts. What is the price per pound of walnuts?
The price per pound of walnuts is $8.3
Cost of 2.4 pounds of walnuts = $19.92
Cost of 1 pound of walnuts = 19.92/2.4 = $8.3
In mathematics, a pound is a unit of measurement that represents an object's mass or the volume of substance it occupies. Pounds essentially tell us how heavy something is. For instance, a soccer ball weighs roughly one pound. Lb or lbs are used to denote pounds, where "lb" stands for libra.
A pound is a unit of weight that is equivalent to 16 ounces, 7,000 grains, or 0.45359237 kg in avoirdupois, and to 12 ounces, 5,760 grains, or 0.37324171216 kg in troy and apothecaries' weight. The abbreviation lb comes from the Latin word libra, which was the origin of the contemporary pound.

Margret is inviting 3 friends to a party. If each friend will get 8 cookies and each box has 6 cookies, how many boxes does Margret need to get?
Answer:
Margret need to get 4 boxes of cookies.
Step-by-step explanation:
Total friends = 3
Cookies each friend will get = 8
Each box has cookies = 6 cookies
How many boxes does Margret need to get?
Total cookies will be= Total friends x Cookies each friend will get
Total cookies will be= 3 x 8 = 24
If one box has 6 cookies and we need total 24 cookies so, divide 24 by 6 to get number of boxes
Number of boxes = Total cookies/ number of cookies in one box
Number of boxes = 24/6
Number of boxes = 4
So, Margret need to get 4 boxes of cookies.

A statistical quality control process for cereal production measures the weight of a cereal box. The population standard deviation is known to be 0.09 ounces. If we wish to estimate the population average cereal box weight to within 0.011 ounces and be 94% confident, how large a sample should be used
Answer:
the sample should be 237
Step-by-step explanation:
The computation of the large the sample be used is shown below:
Given that
Standard deviation = 0.09 ounces
margin of error = 0.011
For 94% confidence interval, the z value be 1.88
As we know that
Margin of error = ((z score × standard deviation) ÷ (Sample size))^2
0.011 = (1.88 × 0.09) ÷ (Sample size))^2
0.011 = 0.1692 ÷ (Sample size))^2
So, the sample size be
= 15.38^2
= 236.60
Hence, the sample should be 237

What is meant by square root?The square root of a number is a value that, when multiplied by itself, yields the original number. The square root is the opposite of squaring a number.
"√" is the standard symbol for the square root. It's known as a radical symbol. The said symbol can be used to represent the square root of a number 'x'.where x is a positive integer.The number beneath the radical symbol is known as the radicand. For instance, the square root of 6 is also known as the radical of 6. Both have the same value.Now, the given expression in the question is;
V= 1/3(3.14)r²
This can be written in the term of V as;
r² = (V×3)/3.14
Taking square root on the both sides;
r = √[(V×3)/3.14]
r = 0.99√V
Thus, the value of the r is obtained as 0.99√V.
