Answer:
-x+8y-27
Step-by-step explanation:
-(x-8y+27)
so the sub symbol is kinda just 1 sense there isnt anything else for there
-1(x-8y+27)
now just like group them or smt
-1(x)+(-1)(-8y)+(-1x27)
so yea then tou multiply all of them and then
-x+8y-27
also
- x - = +
+ x + = +

Find 8th term for 10,-20,40
Answer:
-1280
Step-by-step explanation:
So, as we can see just by loooing at this geometric sequence, the factor is -2. Let's double check this.
10 * -2 = -20 * -2 = 40
We can just keep multiplying to find the 8th term!
40 * -2 = -80 * -2 = 160 *-2 = -320 * -2 = 640 * -2 = -1280
Sometimes with a short sequence, it is better to just multiply it out. You could also do it like this, though:
[tex]a_{n}=a_{1} *r^{n-1}[/tex]
Here, r = -2. We are looking for the 8th term, which would be 8
Plug in our values:
[tex]a_{8}=10*-2^{7}[/tex]
[tex]-2^{7}=-128\\[/tex]
[tex]10*-128=-1280[/tex]
That is the same answer we got before. I would suggest doing it mathematically if you have a long sequence (15, 100, 300 terms)

(x-3) is not a factor of [tex]2x^3-4x^2-6[/tex]
and the Remainder is 32 .
Using the remainder theorem, which asserts that if x is a factor in a polynomial p(x), then p(a) = 0, we may say that.
Therefore, p(x) = 2x3 - 4x2 - 6 p(3) = 0 if x - 3 is a factor.
So, p(x) = 2x³ - 4x² - 6 If x - 3 is a factor, then
p(3) = 0
So, substituting x = 3 into the equation, we have
p(3) = 2x³ - 4x² - 6
= 2(3)³ - 4(2)² - 6
= 2(27) - 4(4) - 6
= 54 - 16 - 6
= 54 - 22
= 32
Since p(3) ≠ 0.
x - 3 is not a factor

The law of uninhibited growth is express as:
[tex]N(t)=N_0e^{kt}[/tex]where N(t) is the population at time t, N0 is the initial population, k is the growth rate and t is the time. In this case we know that after one day, t=1, the population is 800 and that the initial population was 500; plugging these values and solving for k we have:

Answer:
Explanation:
The median is the value corresponding to the line inside the box. Looking at the box plot, the line is between 8 and 9. Thus,
Median = 8.5
To find the measure of variability, we would find the interquartile range, IQR
IQR = third quartile(Q3) - first quartile(Q1)
The first quartile is the value corresponding to the left end of the box. From the box plot, it is between 5 and 6. Thus,
Q1 = 5.5
The third quartile is the value corresponding to the right end of the box. From the box plot,
Q3 = 11
Thus,
IQR = 11 - 5.5
IQR = 5.5
The range is the difference between the minimum and maximum values. On the box plot,
maximum value = 13
minimum value = 1
Range = 13 - 1
Range = 12

For a certain company, the cost function for producing x items is C(x)=50x+250 and the revenuefunction for selling x items is R(x)=-0.5(x-90)2+4,050. The maximum capacity of the company is 110items.The profit function P(x) is the revenue function R(x) (how much it takes in) minus the cost functionC(x) (how much it spends). In economic models, one typically assumes that a company wants tomaximize its profit, or at least make a profit!Assuming that the company sells all that it produces, what is the profit function?====P(x)=Hint: Profit = Revenue - CostWhat is the domain of P(x)?Hint: Does calculating P(x) make sense when x-10 or x-1,000?The company can choose to produce either 40 or 50 items. What is their profit for each case, andwhich level of production should they choose?Profit when producing 40 items=Profit when producing 50 items=Can you explain, from our model, why the company makes less profit when producing 10 more units?
First, let's calculate the Profit functions which is P(x)=R(x)-C(x)
Let's continue simplifying the function
The profit function is a polynomial function, so the domain is all the real numbers which means x can be any real number
Domain=(-∞,∞)
Calculating x=-10 doesn't make sense because x in all the functions is the number of items, and doesn't make sense to have -10 items, so x shouldn't be negative numbers.
And Calculating x=1000 doesn't make sense either because the problem says "The maximum capacity of the company is 110 items" so if we have x=1000 we are exceeding the limit of items that the company can handle.
Now let's calculate the profit when producing 40 and 50 items (we just need to evaluate those values in the function):
The profit when the company produces 50 items is 500 and the profit when the company produces 40 items is 550.
The company should choose to produce 40 items because is a higher profit in contrast to making 50 items.
According to the function, when we replace the values in X we can see that the term (X^2) grows more than the term X and as you can see the term X^2 is negative which decreases the final result of the profit. Another way to see this is by drawing the function
As you can see the function is a parable and when the number of items "X" is very high the function tends to decrease. The function starts to grow in profit until 40 items (when you find the maximum value of profit) and then the profit function decreases.

shadow at the same time of day? (convert
5 ft 8 inches to feet)
x = 113.2941 is the approximate length of the tree's shadow at the same time of a day.
What is a length?A unit of length is any arbitrarily chosen and widely accepted reference standard for measuring length. The most common units in modern use are metric units, which are used in every country on the planet. In the United States, customary units are also used. British Imperial units are still used in the United Kingdom and other countries for a variety of purposes. SI and non-SI units are subsets of the metric system.
5 feet + 8 inches is equal to 5 feet.
5 feet 8 inches is equal to 5 feet plus (8 inches) * (1 foot 12 inches).
5 feet 8 inches plus (8/12) feet equals 6 feet.
5 feet 8 inches equals 5 feet plus 2/3 feet.
5 feet 8 inches = (5 + (2/3)) feet
5 feet 8 inches = ((15/3) + (2/3)) feet
5 feet 8 inches = ((15+2)/3) feet
5 feet 8 inches = (17/3) feet
5 feet 8 inches = 5.667 feet
A/B = C/D
where
A = height of person
B = length of shadow of person
C = height of tree
D = length of shadow of tree
So we have
A = 17/3
B = 2
C = 321
D = x
A/B = C/D
(17/3)/2 = 321/x
(17/3)*x = 2*321
(17/3)*x = 642
(3/17)*(17/3)*x = (3/17)*642
x = 1926/17 the precise length of the tree's shadow

A health club charges 35% a month for membership fees. Determine whether the cost of membership is proportional to the number of months. Explain your reasoning.
Yes, Because the amount charged grows by $35, a fixed amount, every time the number of months increases by 1.
What exactly does direct proportionality mean?Direct proportion, also known as direct variation, is a relationship between two quantities when their ratio equals a fixed number. The proportional symbol is used to denote it. The fact that the other quantity is inverted here means that the same symbol is really employed to denote inverse proportional.
Direct proportionality applies. This is so that the cost of the membership remains constant no matter how many months you choose to pay for. For instance, the cost is 1 x $35 if you pay for one month. The price increases to 2 x $35 if you pay for two months, which is twice as expensive.

Under plan B, the inn charges $1300 plus $20 for each person in excess of the first 25 who attend. For what size parties will plan B cost less? I do not understand how for Plan b: 1300+20(p-25). I do not understand the part p-25
ANSWER
81 people
EXPLANATION
Let p be the number of people that attend the party.
Under plan A, the inn charges $30 for each person, so the value y of a party for p people is,
[tex]y_A=30x[/tex]Then, under plan B, the cost is $1300 for a maximum of 25 people - this means that if 1 to 25 people attend the party, the cost is the same, $1300. For each person in excess of the first 25 - this means for 26, 27, 28, etc, the inn charges $20 each. The cost for plan B is,
[tex]y_B=1300+20(p-25)[/tex]The last part, (p - 25), is the part of the equation that separates the first 25 attendees. This equation works for 25 people or more, but it is okay to solve this problem. Note that for p = 25, the cost for plan A is,
[tex]y_A=30\cdot25=750[/tex]Which is less than the cost of plan B ($1300).
We have to find for what number of people attending the party, the cost of plan B is less than the cost of plan A,
[tex]y_BThis is,[tex]1300+20(p-25)<30p[/tex]We have to solve this for p. First, apply the distributive property of multiplication over addition/subtract4ion to the 20,
[tex]\begin{gathered} 1300+20p-20\cdot25<30p \\ 1300+20p-500<30p \end{gathered}[/tex]Add like terms,
[tex]\begin{gathered} (1300-500)+20p<30p \\ 800+20p<30p \end{gathered}[/tex]Now, subtract 20p from both sides,
[tex]\begin{gathered} 800+20p-20p<30p-20p \\ 800<10p \end{gathered}[/tex]And divide both sides by 10,
[tex]\begin{gathered} \frac{800}{10}<\frac{10p}{10} \\ 80For 80 people, the costs of the plans are,
[tex]\begin{gathered} y_A=30\cdot80=2400 \\ y_B=1300+20(80-25)=1300+20\cdot55=1300+1100=2400 \end{gathered}[/tex]Both have the same cost. The solution to the inequation was the number of people, p, is more than 80. This means that for 81 people the cost of plan B should be less than the cost of plan A,
[tex]\begin{gathered} y_A=30\cdot81=2430 \\ y_B=1300+20(81-25)=2420 \end{gathered}[/tex]For 81 people, plan B costs $10 less than plan A.

Here we have f(x) defined as:
f(x) = -x - 7
Now, we define a general linear function as:
g(x) = m*x + b
Where m is the slope and b is the y-intercept.
Now, we can rewrite f(x) as:
