Answer:
The pro is Political Control, the cons, however, are many.
Step-by-step explanation:
However, A Socialist Economy cons outweigh its pros. The only thing that is a PRO is you dictating it, preventing people from success. Wanna know the cons? The Cons are more Regulations, to which chokes more businesses of their money, they function, & motive. To which it has a chain reaction of: The Businesses not employing people, more people are out of work, which means more people ain't buying stuff to support the businesses, which means the businesses are out of business, they shut down.
The Economy ain't something that you can stop, or go, & it ain't statistics. An Economy is just.. people, that's it. It's just people, they are the ones that work, run businesses & factories, they are the ones that buy N' sell. They create, craft, invent, innovate, etc.

[tex]\left|\begin{array}{c|c}x&y\\--&--\\1&9\\2&6\\3&4\\4&\dfrac83\\\\5&\dfrac{16}{9}\end{array}\right|[/tex]
Answer:
(B) [tex]\dfrac{2}{3}[/tex]
Step-by-step explanation:
An exponential function is a function of the form
[tex]y= a (b)^{x}[/tex]
where a is the initial value and b is the multiplicative rate of change
When x=2, y=6, we have:
[tex]6= a (b)^{2}[/tex]
When x=3, y=4, we have:
[tex]4= a (b)^{3}[/tex]
Dividing the two equations:
[tex]\dfrac{a (b)^{3}}{a (b)^{2}} =\dfrac{6}{9} \\b=\dfrac{6}{9}\\b=\dfrac{2}{3}[/tex]
The multiplicative rate of change, b is [tex]\dfrac{2}{3}[/tex].
The correct option is B.

c. How many ways can a total inventory of 30 batteries be distributed among the eight different types if the inventory includes at most three A7b batteries?
Answers
Answer:
a. 10295472 ways
b. 4272048 ways
c. 6023424 ways
Step-by-step explanation:
Given that:
Camera shop stocks ----- 8 different types of batteries
one of which is ---- A76
Assume that there are ------ at least 30 batteries of each type.
a.
How many ways can a total inventory of 30 batteries be distributed among the eight different types.
The number of ways a total inventory of 30 batteries be distributed is :
[tex]= \left \{ {{30+8-1} \atop {30}} \right. \}[/tex]
[tex]= \left \{ {{37} \atop {30}} \right. \}[/tex]
[tex]=\dfrac{37!}{30! *7!}[/tex]
[tex]= \dfrac{37*36*35*34*33*32*31*30!}{30!*7*6*5*4*3*2*1}[/tex]
[tex]= \dfrac{37*36*35*34*33*32*31}{7*6*5*4*3*2*1}[/tex]
= 10295472 ways
b.
How many ways can a total inventory of 30 batteries be distributed among the eight different types if the inventory must include at least four A76 batteries?
If we must include 4 A76 batteries; then the number of ways a total inventory of 30 batteries can be distributed among eight different types of batteries will be:
30 - 4 = 26 batteries
Now;
[tex]= \left \{ {{26+8-1} \atop {26}} \right. \}[/tex]
[tex]= \left \{ {{33} \atop {26}} \right. \}[/tex]
[tex]=\dfrac{33!}{26! \ \ 7!}[/tex]
[tex]=\dfrac{33*32*31*30*29*28*27*26!}{26! \ * \ 7*6*5*4*3*2*1}[/tex]
[tex]=\dfrac{33*32*31*30*29*28*27}{ \ 7*6*5*4*3*2*1}[/tex]
= 4272048 ways
c. If we must include at most three A7b batteries. the number of ways that a total inventory of 30 batteries can be distributed among eight different types of inventory is:
[tex]= \sum \limits ^3 _{x=0} \left \{ {{(30-x)+7-1} \atop {30-x}} \right. \} \\ \\ \\ = \sum \limits ^3 _{x=0} \left \{ {{(30-0)+7-1} \atop {30-0}} \right. \} = (^{36}_{30})+(^{35}_{29})+ (^{34}_{28})+ (^{33}_{27})[/tex]
[tex]= \dfrac{36!}{30! * 6!} + \dfrac{35!}{29! * 6!} + \dfrac{34!}{28! * 6!} + \dfrac{33!}{27! * 6!}[/tex]
= 1947792 + 1623160 + 1344904 + 1107568
= 6023424 ways

Answers
Answer:
this lesson, we will investigate the relationship between the distance traveled, the rate or speed or travel, and the time that it takes to travel that distance at that rate. We will also look at a few other related products.
Distance = (Rate)(Time)
The equation that relates distance, rate, and time is
d = rt
Where d is the distance traveled, r is the rate, and t is the time. On the CAHSEE exam, you will be given two of these and will be asked to use the above equation to find
took Markus half an hour to drive home from work. He averaged 34 miles per hour. How far does Markus live from his work?SolutionWe are given that it takes 1/2 an hour for the trip. This is a time: t = 1/2We are given that he averages 34 miles per hour. This is a rate: r = 34We are asked how few he has traveled. This is a distance. We use the d=rt equation: d = rt = (34)(1/2) = 17Answer:
2.5 hours
Step-by-step explanation:
First, try rewriting Jenny's speed in it's fraction form: 6 mi/hr
Next, use the units to set up an equation that relates Jenny's speed to the distance they want to travel. Let's call the unknown time t:
6mi/hr=15mi/t
1/t=6/15 (mi/hr•1/mi)
t=15/6 (hrs/mi•mi)= 15/6 (hrs•mi/mi)= 15/6 hrs
t=2.5hrs
So it'd take Jenny 2.5hrs at 6mph to go 15 miles. The key here is to keep track of the units. You can treat them like fractions and reduce them away as if they were numbers or variables.
Write the equation of each line in slope-intercept form.
(If possible please show work)
Answers
Answer:
[tex]\displaystyle y = -\frac{2}{3}\, x - 9[/tex].
Step-by-step explanation:
The slope-intercept form of a line on a cartesian plane should be in the form:
[tex]y = m\, x + b[/tex],
where:
[tex]m[/tex] is the slope of the line, while [tex]b[/tex] is the [tex]y[/tex]-coordinate of the point where the line intersects the [tex]y[/tex]-axis.The question states that the slope of this line is [tex]\displaystyle -\frac{2}{3}[/tex]. In other words, [tex]\displaystyle m = -\frac{2}{3}[/tex]. The next step is to find the value of [tex]b[/tex]. That could be done using the information that the point [tex](-6,\, -5)[/tex] is on this line.
Note that the slope-intercept form of a line [tex]y = m\, x + b[/tex] is essentially an equation about [tex]x[/tex] and [tex]y[/tex]. For a point [tex](x_0,\, y_0)[/tex] to be on that line, [tex]x = x_0[/tex] and [tex]y = y_0[/tex] should satisfy its equation. In other words, it must be true that [tex]y_0 = m\, x_0 + b[/tex].
For the point [tex](-6,\, -5)[/tex], [tex]x_0 = -6[/tex] and [tex]y_0 = -5[/tex]. The equation would be:
[tex]\underbrace{-5}_{y_0} = m \times \underbrace{(-6)}_{x_0}+ b[/tex].
Besides, the slope of this line is already known to be [tex]\displaystyle m = -\frac{2}{3}[/tex]. Therefore, this equation would become:
[tex]\displaystyle \underbrace{-5}_{y_0} = \underbrace{\left(-\frac{2}{3}\right)}_{m} \times \underbrace{(-6)}_{x_0}+ b[/tex].
Solve this equation for [tex]b[/tex]:
[tex]b = -9[/tex].
Hence, the slope-intercept form ([tex]y = m\, x + b[/tex]) of this line would be:
[tex]\displaystyle y = -\frac{2}{3}\, x - 9[/tex].

A fish population grew according to the following quadratic model, the number of fish a day is given by
P(t)=800t-t^2
What is the initial growth rate a t=0
Answers
Answer:
800 fish per day is the initial growth rate of the fish population
Step-by-step explanation:
The growth rate is the derivative of the population function with respect to time (t). Therefore, we need to calculate the derivative of P(t) and evaluate it at t=0:
[tex]\frac{d\,P(t)}{dt} =800-2\,t\\[/tex]

I have k quarters, five less quarters than nickels and one more than twice as many dimes as quarters. Find the value of the coins in cents in terms of k.
Answers
Answer:
(35k + 20) cents
Step-by-step explanation:
First of all, let us have the value of each unit:
1 quarter = 25 cents
1 nickel = 5 cents
1 dime = 10 cents
Given that number of quarter = k
Quarters are 5 lesser than Nickels, so number of nickels = k+5
One more than twice as many dimes as quarters:
k = 2 [tex]\times[/tex] Number of Dimes + 1
So, number of dimes = [tex]\frac{1}{2}(k-1)[/tex]
Value of quarters = [tex]25 \times k[/tex] cents
Value of nickels = [tex]5 \times (k+5) = (5k+25)\ cents[/tex]
Value of dimes = [tex]\frac{1}{2}(k-1) \times 10 = (5k-5)\ cents[/tex]
So, total value of coins =
[tex]25k + 5k +25 +5k-5\\\Rightarrow (35k+20)\ cents[/tex]
The marketing research department of a computer company used a large city to test market the firm's new laptop. The department found the relationship between price p (dollars per unit) and the demand x (units per week) was given approximately by the following equation.
p= 1275 = 0.17x^2 0 < x < 80
So, weekly revenue can be approximated by the following equation.
R(x)= rp = 1275x- 0.17x^3 0 < x <80
Required:
a. Find the local extrema for the revenue function. What is/are the local maximum/a?
b. On which intervals is the graph of the revenue function concave upward?
c. On which intervals is the graph of the revenue function concave downward?
Answers
Answer:
a. Local maximum = 50 units per week.
b. The graph is never concave upward.
c. (0, 80)
Step-by-step explanation:
a. The revenue function is:
[tex]R(x) = 1275x-0.17x^3[/tex]
The derivate of the revenue function for which R'(x) = 0 gives us the local extrema:
[tex]R'(x) =0= 1275-0.51x^2\\x=\sqrt{2,500}\\x=50[/tex]
The second derivate of the revenue function determines if x =50 is local maximum or minimum:
[tex]R''(x) = -1.02x\\R''(50) = -1.02*50=-51\\[/tex]
Since the second derivate yields a negative value, x = 50 units per week is a local maximum.
b. Since there are no local minimums in the range of 0 < x < 80, the graph is never concave upward.
c. Since there is only one local maximum in the range of 0 < x < 80, the graph is concave downward from x>0 to x<80 or (0, 80)

Y = y0e-0.693(t½)
Amount remaining after 4 days
5.9413 grams
Step-by-step explanation:
The formula will he given by
Y = y0e-k(t½)
The half life t½ for this radioactive substance is a day.
Initial mass y0 = 95 grams
Mass after one day = 95/2
Mass after one day = 47.5
.
Value of the decay constant k is not given, let's look for k.
Y = y0e-k(t½)
47.5= 95e-k(1)
47.5/95= e-k(1)
0.5= e-k(1)
In 0.5 = -k
-0.693= -k
0.693 = k
Y = y0e-0.693(t½)
Amount remaining after 4 days
Y = y0e-0.693(t½)
Y = 95e-0.693(4)
Y= 95e-2.772
Y= 95(0.06254)
Y= 5.9413 grams
A publishing company sells 100,000 copies of certain books each year. It costs the company $1 to store each book for a year. Each time it must print additional copies, it costs the company $500 to set up the presses. How many books should the company produce during each printing in order to minimize its total storage and setup costs?
Answers
Answer:
10,000 books
Step-by-step explanation:
Let x be the number of print runs per year and let y the number of books per print run.
Thus, xy = 100,000.
Now from the question, we only start a new print run when we have sold all books in the storage. Thus;
Per print run we now have a cost of;
(x * 1)/(y * 2)
This is because right after the print run, we have y books that last 1/n years (until the next print run). Now, if we plot number of books in storage vs time, we will see a sawtooth pattern where the spikes begin at each print run and will linearly decrease to 0 until the next sprint run which implies constant demand. The area of each triangle will be how many book⋅years we have to pay the storage for. This area is;
(y * (1/x))/2
We'll have to multiply this number by 1 so we can then we get the storage cost per printrun:
(y * (1/x))/2 * 1 = y/2x
Since we do x print runs, the total storage costs is; y/2x * x = y/2
The total print run cost is (500 * x). Therefore, the total cost is;
C_total = (500x) + (y/2)
From initially, we saw that;
xy = 100000
So,x = 100,000/y
C_total = (500*100,000/y) + (y/2)
C_total = 50000000/y + y/2
To minimize its total storage and setup costs, we will find the derivative of the total cost and equate to zero.
So;
dC/dx = -50000000/y² + 1/2
At dC/dx = 0,we have;
0 = -50000000/y² + 1/2
50000000/y² = 1/2
2 × 50000000 = y²
y = √2 × 50000000
y = 10,000 books

A pallet of floor tiles contains 40 cases of tiles and the yard has 10 complete pallets of tile. If you remove 180 cases for one customer how many cases of tiles will be remaining in the yard? *
Answers
Answer:
220 cases
Step-by-step explanation:
Each pallet contains 40 cases of tiles.
The yard has 10 complete pallets.
The total number of cases of tiles is therefore:
40 * 10 = 400 cases

Answers
Answer: c) rotation of 180° & shift right 1 unit and down 2 units
Step-by-step explanation:
Rotation of 180° changes the signs of x and y
(x, y) → (-x, -y)
Shift right one unit adds 1 to x, Shift two down subtracts 2 from y
(-x, -y) → (-x + 1, -y - 2)
(x, y) (-x + 1, -y - 2)
(-1, -2) → (2, 0)
(-4, -1) → (5, -1)
(-4, -3) → (5, 1)
