A supply company manufactures copy machines. The unit cost C (the cost in dollars to make each copy machine) depends on the number of machines made. If
x machines are made, then the unit cost is given by the function C(x)=1.2²-600x+82,738. What is the minimum unit cost?
Do not round your answer.
The minimum unit cost is 7738 when the function is C(x)=1.2x²-600x+82,738
What is meant by unit cost?A company's unit cost is the cost of producing, storing, and selling one unit of a specific product. Unit costs encompass all fixed and variable production costs. A cost unit is a quantity measuring unit for a product or service.
A unit cost is the overall cost incurred by a business to manufacture, store, and sell one unit of a specific product or service. Unit costs are the same as cost of goods sold (COGS). This accounting metric incorporates all fixed and variable expenses related with the manufacture of a good or service.
Given,
C(x)=1.2x²-600x+82,738
Minimum value [tex]C_{min}[/tex]=c-(b²/4a)
Where a=1.2, b=-600, c=82738
[tex]C(x)_{min}[/tex]=82738-((-600)²/4(1.2))
=82738-(360000/4.8)
=7738
Therefore, the minimum unit cost is 7738.
Hence, the minimum unit cost is 7738 when the function is C(x)=1.2x²-600x+82,738

The speedup of a parallel algorithm will eventually reach some limit.
What is parallel algorithm?
An algorithm is a set of instructions that takes input from the user and, after doing some calculations, generates an output. A parallel algorithm is one that can carry out multiple operations simultaneously on various processing units and then combines all of the separate outputs to get the desired outcome.
An algorithm that can execute several instructions concurrently on various processing devices and then aggregate all of the individual outputs to produce the final result is known as a parallel algorithm.
Because a parallel algorithm's speedup is never equal to the number of processors, it ultimately reaches a limit beyond which it can no longer be accelerated. At that point, the algorithm will no longer be accelerated and the speedup will stop.
Hence, the speedup of a parallel algorithm will eventually reach some limit.

What do you mean by system of linear equation?
A set of two linear equations with two variables is a system of linear equations. There are infinitely many possible solutions to a linear equation with two variables. There can be a single solution to a system of two linear equations with two variables that satisfies both solutions. It is necessary to combine two equations with two variables into one equation with one variable while solving a system of equations.
Total number of tickets = 60
Cost of 1 kid ticket = $3
Cost of 1 adult ticket = $5
Total profit = $220
Let number of kid tickets = x
number of adult tickets = y
According to question:
x + y = 60 ......(1)
3x + 5y = 220 ........(2)
Substitute the value of x from eq(1) to eq(2)
3(60 - y) + 5y = 220
180 - 3y + 5y = 220
180 + 2y = 220
2y = 220 - 180
2y = 40
y = 40/2
y = 20
Substitute this value of y in eq(1)
x + 20 = 60
x = 60 - 20
x = 40

How do I prove that the square of an odd number is always one more than a multiple of 8?
The proper way that you can prove that the square of an odd number is always one more than a multiple of eight is by using an example.
What is an example?An example is a term that refers to a tool that is intended to explain, illustrate, or prove a general statement. When we want to explain a procedure we can give an example (that we have previously chosen) to seek to clarify the understanding of a phenomenon or process.
How to make an example for this case?To prove that the square of an odd number is always a multiple of eight, the first step is to find the square of any odd number. Subsequently, we must subtract 1 from the result. Finally we must divide the previous result by 8 and it must give us an exact number (not a decimal).
3 * 3 = 9
9 - 1 = 8
8 / 8 = 1
123 * 123 = 15,129
15,129 - 1 = 15,128
15,128 / 8 = 1,891
9 * 9 = 81
81 - 1 = 80
80 / 8 = 10

a penny is thrown from the top of a 52.6-meter building and hits the ground 3.31 seconds after it was thrown. the penny reached its maximum height above the ground 0.85 seconds after it was thrown. define a quadratic function, h , that expresses the height of the penny above the ground (measured in meters) as a function of the number of seconds elapsed since the penny was thrown, t.
The quadratic function which models the motion of the penny is
h(t) = -4.9t² -0.327761 t + 52.6
and the maximum height reached is 57.43
h(t) = - 0.5gt² + vt + h
g = 9.8 m/s²
h = 52.6 m
v = ?
For v,
h(t) = -0.5gt² + vt + 52.6
h(t) = - 4.9t² + vt + 52.6
Time when penny hits the ground ; t = 3.31
h(3.31) = 0
0 = -4.9(3.31)² + v(3.31) + 52.6
0 = -53.68489 + 3.31v +52.6
3.31v = -1.08489
v = -1.08489/3.31
v = -0.327761 m/s
Therefore,
h(t) = -4.9t² -0.327761 t + 52.6
2.) Maximum height of the penny above the ground
t = 0.85 seconds
h(0.85) = -4.9(0.85^2)-0.327761 (0.85) + 52.6
Maximum height reached = 57.43 meters
Therefore, the maximum height reached is 57.43 meters.
An object changing its position with regard to time is referred to as motion.

Find the slope of the line that contains (−5, −3) and (8, −1).
Work Shown:
[tex](x_1,y_1) = (-5,-3) \text{ and } (x_2,y_2) = (8,-1)\\\\m = \text{slope} = \frac{\text{rise}}{\text{run}} = \frac{\text{change in y}}{\text{change in x}}\\\\m = \frac{\text{y}_{2} - \text{y}_{1}}{\text{x}_{2} - \text{x}_{1}}\\\\m = \frac{-1 - (-3)}{8 - (-5)}\\\\m = \frac{-1 + 3}{8 + 5}\\\\m = \boldsymbol{\frac{2}{13}}\\\\[/tex]
A slope of 2/13 means we go up 2 units and to the right 13 units. If starting at (-5,-3) and following this movement pattern of "up 2, right 13", then we arrive at (8,-1).
if the mean and mode are 15 and 10, respectively, then determine the potential range of the median for a positively skewed distribution
The median will be greater than 10 and less than 15.
Given,
The mean of the skewed distribution = 15
The mode of the skewed distribution = 10
We have to find the potential range of the median for a positively skewed distribution;
Here,
The empirical relationship between mean, median, and mode for a frequency distribution that is positively skewed is mean > median > mode. Based on this, the range of the median is 15 > median > 10 if the mean is 15 and the mode is 10.
Therefore,

Using polar coordinates, the result for integral is - 0.448[tex]\pi[/tex]
What is polar co-ordinates?
In arithmetic, the polar coordinate system may be a two-dimensional organization within which every purpose on a plane is set by a distance from a indicator and an angle from a reference direction.
Main body:
The most used relation for polar coordinates is:
[tex]x^{2} +y ^{2} =r^{2}[/tex]
An integral in Cartesian coordinates is converted to polar using:
[tex]\int\int{f(x,y)} \, dA = \int\int{ f(r, \beta )d\beta[/tex]
In this problem:
f(x,y) = sin [tex]x^{2} +y^{2}[/tex]
thus
f(r,[tex]\beta[/tex]) = sin[tex]r^{2}[/tex]
Region between the circles with center at the origin and radii 1 and 3, thus the inner limits of integration are r =1 and r =3.
First quadrant, thus, the outer limits of integration are: [tex]\beta[/tex] = 0,[tex]\beta[/tex] = [tex]\pi /2[/tex].
The polar integral is:
I = [tex]\int\limits^3_1 {sinr^{2} r} \, dr[/tex]
Using substitution:
u =[tex]r^{2}[/tex] ⇒ du = 2rdr⇒ dr = du /2
I = 1/2[tex]\int\ {sin u} \, du[/tex]
= -[tex]cos r^{2[/tex] /2 where limits are 3, 1
Applying the fundamental theorem of calculus:
I = [tex]-cos 5^{2} /2[/tex][tex]-cos1^{2}/2[/tex]
I = - 0.996
Then, the outer integral is:
O =[tex]\int\limits^\pi _0 {-0.996} \, d\beta[/tex]
O= - 0.448[tex]\pi[/tex]
Hence the result for integral is - 0.448[tex]\pi[/tex]

Use differentials to estimate the propagated error in the measurement of the side of the cube.
The propagated error in the measurement of the side of the cube is 0.001.
We know that,
the volume of a cube is dependent on the length of the edge, s, which is given by the equation,
V = [tex]s^{3}[/tex].
With this we determine that the given cube has an edge of 27 = [tex]s^{3}[/tex]
⇒ s = 3 inches.
Now we can acquire the differential of the equation for the volume of the cube with the following equations.
V = [tex]s^{3}[/tex]
dV = d([tex]s^{3}[/tex])
dV = 3[tex]s^{2}[/tex] ds
We have given that volume of the cube is 0.027.
That is dV = 0.027 and s = 3
we simply plug in the given and then solve for ds to determine the error in the measurement of the edge of the cube.
dV = 3[tex]s^{2}[/tex] ds
0.027 = 3(3)²ds
0.027 = 27ds
0.001 = ds

Angle a is vertically opposite to angle b.
Vertically opposite angles are congruent.
Therefore,
