Answer:
[tex]f(1)=70[/tex]
[tex]f(n)=f(n-1)+6[/tex]
Step-by-step explanation:
One is given the following function:
[tex]f(n)=64+6n[/tex]
One is asked to evaluate the function for [tex](f(1))[/tex], substitute [tex](1)[/tex] in place of [tex](n)[/tex], and simplify to evaluate:
[tex]f(1)=64+6(1)[/tex]
[tex]f(1)=64+6[/tex]
[tex]f(1)=70[/tex]
A recursive formula is another method used to represent the formula of a sequence such that each term is expressed as a function of the last term in the sequence. In this case, one is asked to find the recursive formula of an arithmetic sequence: that is, a sequence of numbers where the difference between any two consecutive terms is constant. The following general formula is used to represent the recursive formula of an arithmetic sequence:
[tex]a_n=a_(_n_-_1_)+d[/tex]
Where ([tex]a_n[/tex]) is the evaluator term ([tex]a_(_n_-_1_)[/tex]) represents the term before the evaluator term, and (d) represents the common difference (the result attained from subtracting two consecutive terms). In this case (and in the case for most arithmetic sequences), the common difference can be found in the standard formula of the function. It is the coefficient of the variable (n) or the input variable. Substitute this into the recursive formula, then rewrite the recursive formula such that it suits the needs of the given problem,
[tex]a_n=a_(_n_-_1_)+d[/tex]
[tex]a_n=a_(_n_-_1_)+6[/tex]
[tex]f(n)=f(n-1)+6[/tex]
Find the linear function f if f^-1(2)=-1 and f^-1 (-9)=3
Answer:
[tex]\displaystyle f(x) = -\frac{11}{4}(x + 1) + 2[/tex]
Step-by-step explanation:
We want to find the linear function given that:
[tex]f^{-1}(2) = -1\text{ and } f^{-1} (-9) = 3[/tex]
Recall that by the definition of inverse functions:
[tex]\displaystyle \text{If } f(a) = b\text{ then } f^{-1}(b) = a[/tex]
In other words, f(-1) = 2 and f(3) = -9.
This yields two points: (-1, 2) and (3, -9).
Find the slope of the linear function:
[tex]\displaystyle m = \frac{\Delta y}{\Delta x} = \frac{(-9) - (2)}{(3) -(-1)} = -\frac{11}{4}[/tex]
From point-slope form:
[tex]\displaystyle y - (2) = -\frac{11}{4}( x- (-1))[/tex]
Hence:
[tex]\displaystyle f(x) = -\frac{11}{4}(x + 1) + 2[/tex]
We can simplify if desired:
[tex]\displaystyle f(x) = -\frac{11}{4}x -\frac{3}{4}[/tex]

Answer:
The statement in the question is wrong. The series actually diverges.
Step-by-step explanation:
We compute
[tex]\lim_{n\to\infty}\frac{n^2}{(n+1)^2}=\lim_{n\to\infty}\left(\frac{n^2}{n^2+2n+1}\cdot\frac{1/n^2}{1/n^2}\right)=\lim_{n\to\infty}\frac1{1+2/n+1/n^2}=\frac1{1+0+0}=1\ne0[/tex]
Therefore, by the series divergence test, the series [tex]\sum_{n=1}^\infty\frac{n^2}{(n+1)^2}[/tex] diverges.
EDIT: To VectorFundament120, if [tex](x_n)_{n\in\mathbb N}[/tex] is a sequence, both [tex]\lim x_n[/tex] and [tex]\lim_{n\to\infty}x_n[/tex] are common notation for its limit. The former is not wrong but I have switched to the latter if that helps.

А
Add 3 to both sides
B
Subtract 3 from both sides
с
Multiply -3 to both sides
D
Divide -3 from both sides
(b)
What is the solution to the give equation?
Given: -3 + x = 4
x = "write the answer (number only) in the answer box"
Answer:
(a) A
(b) x = 7
Step-by-step explanation:
(a) Given : -3 + 2x = 4
Step 1: Isolate the x to one side. To do so, we get rid of -3 by adding 3 to both sides. (-3 + 3 =0)
2x = 4 + 3
(b) -3 + x = 4
x = 4 + 3
= 7

Answer:
b = -3
Step-by-step explanation:
-4b + 3(6 - 7b) = 93
-4b + 18 - 21b = 93
-4b - 21b = 93 - 18
-25b = 75
[tex]\sf{b = \frac{75}{ - 25} }[/tex]
b = -3
b = - 3
Step-by-step explanation:
-4b + 3(6-7b) = 93
-4b + 18 - 21b = 93
-25b + 18 = 93
-25b = 93 - 18
-25b = 75
b = 75 : - 25
b = - 3

We are asked to find multiple probabilities.
We got to find the number of combinations posible,
Use the combinations formula
[tex]c {}^{n} _r{?} = \frac{(r + n - 1) \: fractorial).}{r \: fractorial(n - 1)fractorial} [/tex]
For math this is read as,
if n choose r,( r+n-1)!/r!(n-1)!.
Where r is how many things we need from and n is the number of things we choose from.
We need 2 things and we have 24 objects to pick from.
So r=2 N equal=24
Which equal
25!/2!(23)!
Which equals
[tex]300[/tex]
So there are 300 possible combinations.
Using
For the 1st question, Since we are given two independent events, we can just multiply the number of good articles by major.
[tex]14 \times 4 = 56[/tex]
So this means the probability is
[tex] \frac{56}{300} = \frac{14}{75} [/tex]
Which is 19%
For the 2nd question, the can multiply the number of minor articles by major articles.
[tex]6 \times 4 = 24[/tex]
So the probability
is
[tex] \frac{24}{300} = \frac{8}{100} = \frac{2}{25} [/tex]
Which is equal to 8%

Point O is the centroid of triangle ABC. If OD=3x -2 and OC= 5x, find x.
At centroid medians bisect each other in the ratio 2:1
[tex]\\ \sf\longmapsto OC=2(OD)[/tex]
[tex]\\ \sf\longmapsto 2(3x-2)=5x[/tex]
[tex]\\ \sf\longmapsto 6x-4=5x[/tex]
[tex]\\ \sf\longmapsto 6x-5x=4[/tex]
[tex]\\ \sf\longmapsto x=4[/tex]
The value of x is 4, when we are given O is the centroid of the triangle ABC, OD = 3x - 2, and OC = 5x.
What is the centroid of a triangle?The center of the thing is represented by its centroid. The centroid of a triangle is the location where the triangle's three medians connect. The junction of all three medians is another definition for it. The median is a line that connects the middle of a side to the triangle's opposite vertex. The median is divided by the centroid of the triangle in a ratio of 2:1.
How to solve the question?In the question, we are given that O is the centroid of triangle ABC, and are asked to find the value of x, for which OD = 3x - 2, and OC = 5x.
We know that the median is divided by the centroid of the triangle in a ratio of 2:1.
Thus, the median CD is divided by the ratio of 2:1 as,
2/1 = OC/OD,
or, 2/1 = (5x)/(3x - 2),
or, 2(3x - 2) = 1(5x) {Cross-multiplying},
or, 6x - 4 = 5x,
or, 6x - 5x = 4,
or, x = 4.
Thus, the value of x is 4, when we are given O is the centroid of the triangle ABC, OD = 3x - 2, and OC = 5x.

Write the equation of a line that passes through ( 4, 6), and has a slope of 1/3
Answer:
y = 1/3x + 14/3
Step-by-step explanation:
y = mx + b
we know the slope, so the equation would be --> y = 1/3x + b
Now we plug in the coordinates of the given point (4, 6) the line goes through, and solve for b:
y = 1/3x + b
6 = 1/3(4) + b
6 = 4/3 + b
-4/3 -4/3

14/3 = b

I am still stuck on this basic math question. Rosa has 3 3/4 pounds of dough. She uses 1/8 of a pound for one roll. How many rolls could be made from Rosa's dough? I was told 30. But how did they get this answer?
Step-by-step explanation:
First convert the amount of dough into an improper fraction:
[tex]3\frac{3}{4}\:\text{lbs} = \dfrac{15}{4}\:\text{lbs}[/tex]
Each roll is 1/8 lb so divide the amount of dough by this amount:
[tex]\dfrac{\left(\dfrac{15}{4}\:\text{lbs}\right)}{\left(\frac{1}{8}\:\text{lb/roll}\right)} = \left(\dfrac{15}{4}\:\text{lbs}\right)\cdot \left(8\:\dfrac{\text{roll}}{\text{lb}}\right) = 30\:\text{rolls}[/tex]
