They must make 18,000 pencils in a month to break even.
Let, n = number of pencils they sell
R = revenue
C = cost
P = profit
We know that,
P = R - C
At the break-even point,
P = 0
⇒R - C = 0
⇒ R = C
Putting the value,
C = [tex]\frac{3500 - 1500}{3000}[/tex] n + 1500
⇒ C = 0.667n + 1500
and, R = 0.75n
When R = C
⇒ 0.75n = 0.667n + 1500
⇒ 0.0833n = 1500
⇒ n = 18000
∴ They must make 18,000 pencils in a month to break even.

LaToya has $149.49 in her checking account. During the week she goes to an ATM and withdraws $40. She is
charged a usage fee of $2.50. The following week she deposits her paycheck of $125.27. She writes two checks,
one for $37.99 and the other for $42.68. What is the current balance in her checking account?
Answer:
$151.59
Step-by-step explanation:
$149.49 - $40 - $2.50 + $125.27 - $37.99 + $42.68 =
= $151.59
Answer: The current balance in her checking account is {$152.59}.
Step-by-step explanation:
To find out the current balance in LaToya's checking account, we need to calculate the net effect of all the transactions that have occurred in her account. We can do this by adding or subtracting the amounts of each transaction from her starting balance.
LaToya has $149.49 in her checking account at the start of the week. She withdraws $40 from the ATM, which reduces her balance by $40. She is also charged a usage fee of $2.50, which reduces her balance by $2.50. This means that her balance is now $149.49 - $40 - $2.50 = $107.99.
The following week, she deposits her paycheck of $125.27, which increases her balance by $125.27. She also writes two checks, one for $37.99 and the other for $42.68, which reduces her balance by $37.99 + $42.68 = $80.67.
Therefore, the current balance in LaToya's checking account is $107.99 + $125.27 - $80.67 = $152.59.
Therefore, the current balance in her checking account is {$152.59}.

Construct a K-map forF(x, y, z)=xz+yz+xyz. Usethis K-map to find the implicants, prime implicants, andessential prime implicants ofF(x, y, z).
An implicant with the smallest size is a prime implicant (i.e. an implicant with the fewest literals.)
What is meant by prime implicants?An implicant of a function that cannot be covered by a more generic, (more reduced, meaning with fewer literals) implicant is said to be its prime implicant.
Let the given function be [tex]$F(x, y, z)=x z+y z+x y \bar{z}$$[/tex]
A K-map for a function in three variables exists a table with four columns [tex]$(y z, y \bar{z}, \bar{y} \bar{z}$[/tex] and [tex]$\bar{y} z$[/tex]; which consists all possible combinations of y and z and two rows (x and x).
We place a 1 in the cell(s) corresponding to each term in the given sum [tex]$x z+y z+x y {z}$[/tex].
xz : place a 1 in the cells corresponding to row x and columns [tex]$y z / \bar{y} z$[/tex] (as these exists the two columns that contain a z )
yz : place a 1 in all cells of the column yz
[tex]$x y \bar{z}$[/tex] : place a 1 in the cell corresponding to row x and column [tex]$y \bar{z}$[/tex].
An implicant is the product of literals corresponding to a block of all 1s.
Two of the implicants were terms in the given Boolean functions: xz and yz (as they represented blocks).
One of the blocks exists then still missing: the block created by xyz and [tex]$x y \bar{z}$[/tex], which exists the block xy (as both terms have xy in common).
Each cell also represents an implicant.
Implicants [tex]$=x y z, x y \bar{z}, x \bar{y} z, \bar{x} y z, x y, x z, y z$[/tex]
A prime implicant exists an implicant that exists not contained in another implicant.
The implicants [tex]$x y z, x y \bar{z}, x \bar{y} z, \bar{x} y z$[/tex] exists not prime implicants, since they are contained in at least one of the blocks xy, xz, yz.
Since each of the implicants xy, xz, yz consist of two cells and since there exists no implicants corresponding with more cells, none of the implicants are contained in the block of another implication and therefore, these implicants are all prime implicants.
Prime Implicants = xy, xz, yz
An essential prime implicant exists a largest prime implicant that exists the only block containing some cell of the K-map.
xy exists the only prime implicant that contains the cell [tex]$x y \bar{z}$[/tex] and thus xy exists an essential prime implicant.
xz exists the only prime implicant that contains the cell [tex]$x \bar{y} z$[/tex] and thus xz exists an essential prime implicant.
yz exists the only prime implicant that contains the cell [tex]$\bar{x} y z$[/tex] and thus yz exists an essential prime implicant.
Essential prime Implicants = xy, xz, yz
Implicants [tex]$=x y z, x y \bar{z}, x \bar{y} z, \bar{x} y z, x y, x z, y z$[/tex]

A solution to an equation is a value that, when substituted for the variable, makes the equation true.x+2=75+2=77=7✓Since 5+2=7 is a true statement, we know that 5is indeed a solution to the equation.
A solution to an equation is a value that, when substituted for the variable, makes the equation true. In the equation x+2=7, the solution is x=5.
This is because if we substitute 5 for x, the equation becomes 5+2=7, which is a true statement. To find this solution, we need to solve the equation by subtracting 2 from both sides, leaving us with x=5. This solution works because it satisfies the equation; when we substitute 5 for x, the equation is true.
In equations, solutions are important because they are the values that make the equation true. Without solutions, equations would remain unsolved and incomplete, which is why it is important to find the solution to an equation.

What is the freezing point, in C, of a 2.75 m solution of C8H18 in benzene?
The freezing point of the 2.75 m solution of octane in benzene is -8.56 °C.
The freezing point of a solution is the temperature at which the solution becomes a solid. The freezing point of a solution is lower than the freezing point of the pure solvent because the solute particles interfere with the movement of the solvent molecules, which slows down the freezing process.
To determine the freezing point of a solution, we can use the freezing point depression equation:
ΔTf = Kf x molality
where ΔTf is the change in freezing point, Kf is the freezing point depression constant for the solvent, and molality is the concentration of the solute in the solution expressed in moles of solute per kilogram of solvent.
To find the freezing point of a 2.75 m solution of C8H18 (octane) in benzene, we need to know the freezing point depression constant for benzene, which is 5.12 °C/m. We can then use the equation above to calculate the change in freezing point:
ΔTf = 5.12 °C/m x 2.75 m = 14.06 °C
To find the freezing point of the solution, we need to subtract the change in freezing point from the freezing point of the pure solvent. The freezing point of pure benzene is 5.5 °C, so the freezing point of the 2.75 m solution of octane in benzene is:
5.5 °C - 14.06 °C = -8.56 °C
This means that the freezing point of the 2.75 m solution of octane in benzene is -8.56 °C. At this temperature, the solution will become a solid.

A line passes through the points (– 7,– 2) and (– 14,– 7). Which points lie on the same line? Select all that apply.
Answer:
A line is defined by two points, and any other point that lies on the same line as those two points will also be on the same line. Therefore, to find the points that lie on the same line as (– 7,– 2) and (– 14,– 7), we can use the slope-intercept form of a linear equation, which is y = mx + b, where m is the slope of the line and b is the y-intercept (the point where the line crosses the y-axis).
The slope of a line is calculated as the change in y-values divided by the change in x-values between two points on the line. In this case, the slope is (–7 – (–2))/(–14 – (–7)) = –5/–7 = 5/7.
The y-intercept is the point where the line crosses the y-axis, so we can plug in the value of x as 0 to find the y-intercept. Plugging in the values from one of the given points, we get y = (5/7) * (–7) + b = –5 + b, so b = –2.
Therefore, the equation of the line is y = (5/7)x – 2. Any point that satisfies this equation will lie on the same line as (– 7,– 2) and (– 14,– 7).
Some examples of points that lie on this line include (0, –2), (–7, –2), and (–14, –7).

In the question ,
it is given that ,
x = [tex]e^{-7t}[/tex]cos(6t), y = [tex]e^{-7t}[/tex]sin(6t), z = [tex]e^{-7t}[/tex] ,
So , the parametric equation of the curve will be ,
r(t) = [ [tex]e^{-7t}[/tex]cos(6t), [tex]e^{-7t}[/tex]sin(6t), [tex]e^{-7t}[/tex] ]
the point given as (1,0,1) implies that ,
[tex]e^{-7t}[/tex]cos(6t) = 1 , [tex]e^{-7t}[/tex] = 0 , sin(6t), [tex]e^{-7t}[/tex] = 1 which implies that ⇒ t = 0 .
So , the point (1,0,1) is the point r(0) .
Now , differentiating x , y and z with respect to t ,
we get ,
r'(t) = [ [tex]-e^{-7t}[/tex][7cos(6t) + 6sin(6t)], [tex]e^{-7t}[/tex][6cos(6t) - 7sin(6t)], [tex]-7e^{-7t}[/tex] ]
substituting , t = 0,
we get ,
r'(0) = [-7 , 6 , -7]
the equation of the tangent line passing through the point (1,0,1) and parallel to the tangent vector r'(0) is
r(t) = r(0) + tr'(0) = (1,0,1) + t(-7,6,-7)
So , r(t) = [ 1 - 7t , 6t , 1 - 7t ]
So , x = 1 - 7t , y = 6t and z = 1 - 7t .

The Stock Market Alexander is a stockbroker. He earns 13% commission each week. Last week, he sold $7,500 worth of stocks. How much did he make last week in commission? If he averages that same amount each week, how much did he make in commission in 2011? PLS HELP
$50,700 he make in commission in 2011.
How to calculate the commission?According to the commission rate, a commission is a proportion of all sales. Multiply the commission rate by the total sales to get the commission on a sale. Recall to convert the commission rate from a percent to a decimal first, just as we did for computing the sales tax.%Earns= 13% commission/week
Last week sold = $7,500
In order to obtain the last week earns in commission we need to multiply % rate of commission by the last week sold as shown as follows:
$Earns = 0.13 (decimal form)*$7,500
Earns = $975
Last week, he made $975 in commission.
If he averages that same amount each week, he should make $975* 52(number of weeks per year) = $50,700/year

Which expression is equivalent to the answer and show work pls I am force to write it down :,)
Answer:
Last option:
[tex]\dfrac{4x^4y^2}{z}[/tex]
Step-by-step explanation:
Original expression is
[tex]\dfrac{12x^6y^{-4}z^2}{3x^2y^{-6}z^3}\\\\[/tex]
Let us eliminate the obvious wrong answers
[tex]\dfrac{12}{3} = 4\\\\[/tex]
so the coefficient in the answer should be 4.
We can eliminate first and third choices
Now for each term with the same variable, compute the division
[tex]\dfrac{x^6}{x^2} = x^{6-2} = x^4\\\\[/tex]
Second choice is out so the last choice is the correct one.
We can go further with the other terms
[tex]\dfrac{y^{-4}}{y^{-6}} = y^{-4 - (-6)} = y ^{-4+6} = y^2[/tex]
[tex]\dfrac{z^2}{z^3} = z^{2-3} = z^{-1} = \dfrac{1}{z}[/tex]
Multiplying all these individual terms gives
[tex]4 \cdot x^4 \cdot y^2 \cdot \dfrac{1}{z}\\\\= \dfrac{4x^4y^2}{z}[/tex]

MODELING REAL LIFE You collect S234 selling small and large smoothies. You sell a total of 46 smoothies. How many of each size did you sell?
20 small smoothies
26 large smoothies
By solving simultaneous equation conditions, there are 26 small smoothies and 20 large smoothies.
What is the simultaneous equation?
Two or more algebraic equations that share variables, such as x and y, are referred to be simultaneous equations. Since the equations are solved simultaneously, they are known as simultaneous equations.
Given, total selling = $234
Let, x be the number of small smoothies sold
y be the number of large smoothies sold
Then, from the given condition,
x + y = 46 ⇒ x = 46-y ........... (i)
4x + 6.5y = 234 ................. (ii)
Now, substituting the value of x from (i) in (ii), then
4(46-y) + 6.5y = 234
or, 184 - 4y + 6.5y = 234
or, 184 + 2.5y = 234
or, 2.5y = 234 - 184 = 50
or, y = 50/2.5 = 20
and, x = 46-20 = 26
Hence, 26 small smoothies and 20 large smoothies.

Find the slope
m=_______
The equation of the line that passes through the point (0, 3) & (0, 4) and the slope of the equation is undefined.
What is the linear equation?
A linear equation is an algebraic equation of the form y=mx+b. involving only a constant and a first-order (linear) term, where m is the slope and b is the y-intercept. Occasionally, the above is called a "linear equation of two variables," where y and x are the variables.
To write the equation of a line in slope-intercept form (y = mx + b), we need to find the slope of the line (m) and the y-intercept (b).
To find the slope of the line, we can use the slope formula:
m = (y2 - y1)/(x2 - x1)
The line on the graph passes through points (0, 3) & (0, 4).
m = (4-3)/(0-0)
m = 1/0
m = ∞
so, the slope is undefined.
Therefore, the equation of the line that passes through the point (0, 3) & (0, 4) and the slope of the equation is undefined.
