The explicit rule for the sequence 4, 3 2/3, 3 1/3, 3.... is f(n) = 4 - 1/3(n - 1)
Finding the explicit rule for the sequenceFrom the question, we have the following parameters that can be used in our computation:
4, 3 2/3, 3 1/3, 3....
In the above sequence, we can see that 1/2 is subtracted from the previous term to get the new term
Take for instance
2nd = 4 - 1/3 = 3 2/3
3rd = 3 2/3 - 1/3 = 3 1/3
4th = 3 1/3 - 1/3 = 3
And so on
This means that
First term, a = 4Common difference, d = -1/3So, the explicit rule is
f(n) = a + (n - 1)d
This gives
f(n) = 4 - 1/3(n - 1)
Hence, the explicit formula is f(n) = 4 - 1/3(n - 1)

What meaning of the statement this: subgroups partition groups into subsets of equal size?
Answer:
This statement means that subgroups divide a larger group into smaller groups, and each of these smaller groups has the same number of things in it. For example, if there are 12 people in a group, and they form subgroups of 3 people each in a group, there will be 4 groups total, and each individual subgroup will have 3 people in it.
If a company uses standard costs to record its inventory in the general ledger, what would the journal entry be for a purchase of direct materials with a favorable price variance?
The journal entry for the company is Debit - Raw Materials Inventory - Standard Cost, Credit - Accounts Payable - Actual Cost.
When a company uses standard costs to record its inventory in the general ledger, the journal entry for a purchase of direct materials with a favorable price variance would be as follows
Debit - Raw Materials Inventory - Standard Cost
Credit - Accounts Payable - Actual Cost
The debit entry would record the standard cost of the direct materials purchased, and the credit entry would record the actual cost of the direct materials purchased, which is lower than the standard cost due to the favorable price variance.
It's important to note that this journal entry assumes that the company is using a perpetual inventory system, where the inventory account is updated continuously as purchases and sales occur. If the company is using a periodic inventory system, the journal entry would be different and would involve adjusting the cost of goods sold account at the end of the period.

Suppose that a random variable X is a discrete variable with the following distribution law P(X=k)=c/2^k, k= 0, 1, 2, . . . , Find the value of the constant c. (Using the normalization property of the distribution law)
Answer:
The normalization property of the distribution law states that the sum of probabilities of all possible outcomes must equal 1. In this case, we have:
P(X=k) = c/2^k, for k = 0, 1, 2, ...
To find the value of the constant c, we need to use the normalization property:
∑ P(X=k) = ∑ c/2^k = c/2^0 + c/2^1 + c/2^2 + ... = 1
To simplify this expression, we can use the formula for the sum of an infinite geometric series:
∑ a*r^n = a/(1-r), where a is the first term, r is the common ratio, and n goes from 0 to infinity.
In this case, a = c, r = 1/2, and n goes from 0 to infinity. So we have:
∑ P(X=k) = ∑ c/2^k = c/2^0 + c/2^1 + c/2^2 + ... = c/(1-1/2) = 2c
Setting this expression equal to 1, we get:
2c = 1
c = 1/2
Therefore, the value of the constant c is 1/2.

11. If the revaluation of the asset is higher than the carrying value, the following entries will be made via the revaluation account; Debit Asset account and Credit Capital account of each partner. True/False?
Answer:
False. If the revaluation of the asset is higher than the carrying value, the following entries will be made: Debit Asset account and Credit Revaluation reserve account. The revaluation reserve account is a balance sheet account and does not affect the capital accounts of the partners directly. However, the revaluation reserve may indirectly affect the capital accounts of the partners if the revaluation reserve is distributed to the partners or used to offset losses in the future. It is worth noting that the specific accounting treatment may vary depending on the accounting standards being used by the company.

Answers are: 13FT, 125FT, 313FT, AND 425 FT.
Answer:125
Step-by-step explanation:
the drawing (fountains) was 10 inches apart, but real life was 400. 400/10 = 40. this means that the real life distance is 40x the distance of the drawing.
therefore, multiply 3.125 by 40 as well. you get 125.
Answer: 125 ft
Step-by-step explanation:
Let x be the real remove between the two shows.
At that point, we are able set up the extent:
10 inches / 400 feet = 3.125 inches / x
To illuminate for x, able to cross-multiply and disentangle:
10 inches * x = 400 feet * 3.125 inches
10x = 1250
x = 125 feet
I've been struggling a lot with interpreting what this problem wants me to find.
The plane departs an airport at 9:00 AM and flies 200 mph southwest. A second plane ldeparts the same airport at 9:30 AM and flies 320 mph northwest. Find the bearing of the second plane from the first one at 10:00 AM.
The reason: I've heard some people say a bearing has to be in one direction (north). I've also heard that a bearing has to be an acute angle and some insist there is an answer to this greater than 90º.
I drew out a diagram with a right triangle, legs of 200 and 160 (320 ÷ 2 for the half hour), separated my right triangle into two triangles with 45º angles, and went from there.
Where the hypotenuse and the 160 side meet, the angle is 51.34º. The 200 side makes a 38.66º angle (both came from arctan). I know for a fact there is an 83.66º angle that can be found.
Trouble is, I'm not sure if that's the actual bearing or not. Everything SEEMS correct there, but I've just heard so many other answers on this that I'm not sure who or what to believe!
Figured I'd see what everyone else thought. It's the "second from the first" that I'm struggling with semantically too. I can do the math just fine here.
Answer:
6.34°
Step-by-step explanation:
You want to know the bearing of a second plane from the first at 10 a.m. when the first leaves at 9 a.m. and flies 200 mph SW, while the second leaves at 9:30 a.m. and flies 320 mph NW.
LocationsThe first plane flies for an hour at 200 mph, so is 200 miles from the airport on a bearing of 180° + 45° west of south, or 225°.
The second plane flies for half an hour at 320 mph, so is 160 miles from the airport on a bearing of 360° -45° west of north, or 315°.
DirectionThe vector in the direction of the second plane from the first is found by subtracting the location of the first plane from the second:
vector of interest = (160∠315°) -(200∠225°)
A suitable calculator can tell you the difference is ...
vector of interest = 256∠6.34°
The second plane is on a bearing of 6.34° from the first.
__
Additional comment
You are correct that an angle of 83.66° is involved. That would be the measure of the direction vector counterclockwise from the +x axis. You want the bearing angle, measured clockwise from the +y axis (North), so the angle you're looking for is 90° -83.66° = 6.34°.
If you work enough of these problems, you will find that it doesn't matter how you measure the angles, as long as you do it consistently. The second attachment shows the arithmetic using distance∠bearing. The effect is to swap the x, and y coordinates so that they are (N, E) coordinates, rather than the usual (E, N) coordinates. This doesn't have to be confusing. A diagram usually helps.

E. m(x)=√5x
Answer:
The function f(x) = √x is the square root function.
A vertical translation of a function is a transformation that shifts the graph of the function up or down without changing its shape.
Option (A) is a vertical translation of f(x) because it shifts the graph of f(x) to the right by 5 and then applies three square root operations. However, it is not a vertical translation that shifts the graph up or down.
Option (B) is a vertical translation of f(x) because it shifts the graph of f(x) down by 7 units.
Option (C) is a vertical translation of f(x) because it shifts the graph of f(x) down by 4 units.
Option (D) is a vertical translation of f(x) because it shifts the graph of f(x) up by 3 units.
Option (E) is not a vertical translation of f(x) because it involves multiplying the input of f(x) by a constant factor of 5.
Therefore, the options that are vertical translations of f(x) are (B), (C), and (D).

then adding the resulting equation to the
first equation.
x + 4y = 12
3x - y = 10
Answer:
The answer to your problem is, 3x+6y=9 then -2x-4y=4
Step-by-step explanation:
So first we are going to multiply the first equation by 2 and second equation by 3 and add it.
If there is both x and y terms gets cancelled then we can say there were no solutions at all.
Shown;
A) -2x+4y=4
-3x+6y=6
Which then becomes;
-4x + 8y = 8
-9x + 18y = 18
For, -13x + 26y = 26
B) 3x+y=12-
3x+6y=6
Which we then multiply first equation by 2 and second equation by 3
6x + 2y = 24
-9x + 18x = 18
For, -3x + 20y = 42
C)3x+6y=9
-2x-4y=4
Again multiply first equation by 2 and second equation by 3
6x + 12y = 18
-6x - 12y = 12
Which can equal to:
30
Which both x and y terms becomes 0.
Thus the anwer to your problem is, 3x+6y=9 then -2x-4y=4
Solve using the elimination method, and also determine whether a system is consistent or inconsistent, and whether the equations are dependent or independent.
Please helppp <3
To solve using the elimination method, we need to eliminate one of the variables.
Multiplying the first equation by 3, we get:
9x = 165 - 21y
Now we can write the system as:
9x = 169 - 22y
9x = 165 - 21y
Subtracting the second equation from the first, we get:
0 = 4 - y
Solving for y, we get:
y = 4
Substituting y = 4 in the first equation, we get:
3x = 55 - 7(4)
3x = 27
x = 9
Therefore, the solution to the system is (x, y) = (9, 4).
The system is consistent and independent, since it has a unique solution.
