The value of [tex]a_{4} = 37[/tex].
Here,
The value of [tex]a_{1} = 4[/tex]
And, [tex]a_{n} = 2 a_{n-1} -1[/tex]
We have to find value of [tex]a_{4}[/tex].
What is Sequence?
A sequence is a collection of elements that are arranged according to a specific pattern.
Now,
The value of [tex]a_{1} = 4[/tex]
And, [tex]a_{n} = 2 a_{n-1} -1[/tex]
Then to find value of [tex]a_{4}[/tex], we can find [tex]a_{2} , a_{3}[/tex] as;
[tex]a_{2} = -2(a_{1} ) - 1\\a_{2} = -2(4) - 1\\a_{2} = -9[/tex]
And,
[tex]a_{3} = -2(a_{2} ) - 1\\a_{3} = -2(9) - 1\\a_{3} = -19[/tex]
Hence, the value of [tex]a_{4}[/tex] is;
[tex]a_{4} = -2(a_{3} ) - 1\\a_{4} = -2(-19) - 1\\a_{4} = 37[/tex]
Therefore, The value of [tex]a_{4} = 37[/tex].

Rori read 5 books last month. Here are the number of pages in each book that she read. (120, 106, 94, 100, 180) What is the mean absolute deviation (MAD) of the number of pages in the 5 books Rori read?
Answer:The mean absolute deviation (MAD) of the number of pages in the 5 books Rori read =24
Step-by-step explanation:
To find the the mean absolute deviation (MAD,we start firt by
Getting the mean of all values
Mean =120, 106, 94, 100, 180/5 =600/5=120
Next we subtract the mean value from each value which is called distance
120 -120 = 0
106 -120 = -14
94 -120= -26
100 -120=-20
180 -120=60
Thirldly, we find the mean of the distances ignoring the negative signs
0+14+26+20+60 / 5 = 120/5=24

last year there were 480 students in school and this year it has become 600 find the percentage increase in the number of students
Answer:
25%Steps:
600 - 480 = 120
100(120/480) = 25
Answer:
increase in percentage = 25%
Step-by-step explanation:
here's your solution
==> Total number of students last year = 480
==> Number of students this year = 600
==> Number of increased students = 600 - 480
= 120 students
==> now , in percentage = (120/480)*100
==> percentage increase = 25%

the measure of a base isosceles triangle is 43? what is the measure of the vertex angle
Answer:
The vertex angle is 94 degrees
Step-by-step explanation:
Let the vertex angle be x
Mathematically, the base angles of an isosceles triangle are the same
So if one of the base angles is 43 degrees, then the other base angle would be 43 degrees too
Mathematically, the sum of angles in a triangle is 180 degrees
Thus;
43 + 43 + x = 180
x = 180-86
x = 94 degrees

Graph the logarithmic function f(x) = log2(x - 1) + 2.
anyone know this pls help
Answer:
I graphed it for you in the image below.
Step-by-step explanation:
Graph the logarithmic function f(x) = log2(x - 1) + 2 is attached below.
What is a function?The function is referred to as a particular kind of relationship, every value in the domain is associated with exactly one value in the range. They have a set perimeter and territory.
It is given that the logarithmic function is, f(x) = log2(x - 1) + 2.
The first step in graphing a logarithmic function is to locate some points on the exponential f. (x). The graph will look better as we plot more points, and we can flip the x and y values to get points on the opposite axis. locate the asymptote. The following logarithmic functions can be graphed. Specify the domain and the range.
Thus, the graph is attached below.

the poles for a tent form vertices of a regular decagon. when the poles are properly positioned, what is the measure of the angle formed at a corner of the tent. ( n - 2 ) × 180
Answer:
Each Interior Polygon angle = 180 - [ 360 / number of sides]
Each Angle = 180 - [ 360 / 10]
Each Angle = 180 - 36
Each Angle = 144 degrees

Solve triangle PQR. Round intermediate results to 3 decimal places and final answers to 1 decimal place.
Answer:
[tex]Q = 96.4^\circ[/tex]
[tex]R = 58.4[/tex]
[tex]P =25.2[/tex]
Step-by-step explanation:
Given
See attachment for PQR
Required
Solve the triangle
From the attached triangle, all sidea of the triangle are known.
i.e.
[tex]PQ = 6\\QR=3\\PR=7[/tex]
So, we are to solve for [tex]\angle P, Q \& R[/tex]
Using cosine rule:
[tex]a^2 = b^2 + c^2 - 2bcCosA[/tex]
To solve for Q, we have:
[tex]PR^2 = PQ^2 + QR^2 - 2 * PQ * QR Cos(Q)[/tex]
[tex]7^2 = 6^2 + 3^2 - 2 * 6 * 3 * \cos(Q)[/tex]
[tex]49 = 36 + 9 - 36 * \cos(Q)[/tex]
Collect like terms
[tex]49 - 36 - 9 = - 36 * \cos(Q)[/tex]
[tex]4 = - 36 * \cos(Q)[/tex]
Divide both sides by -36
[tex]\cos(Q) = \frac{-4}{36}[/tex]
[tex]\cos(Q) = -0.1111[/tex]
Take arc cos of both sides
[tex]Q = cos^{-1}(0.1111)[/tex]
[tex]Q = 96.4^\circ[/tex]
To solve for R, we make use of sine rule;
[tex]\frac{a}{\sin A} = \frac{b}{\sin B}[/tex]
So, we have:
[tex]\frac{PQ}{\sin R} = \frac{PR}{\sin Q}[/tex]
[tex]\frac{6}{\sin R} = \frac{7}{\sin 96.4}[/tex]
Cross multiply
[tex]\sin R * 7 = 6 * \sin 96.4[/tex]
Solve for sin R
[tex]\sin R = \frac{6 * \sin 96.4}{7}[/tex]
[tex]\sin R = \frac{6 * \0.9938}{7}[/tex]
[tex]\sin R = 0.8518[/tex]
Take arc sin of both sides
[tex]R = sin^{-1}(0.8518)[/tex]
[tex]R = 58.4[/tex]
Solving P:
[tex]P+ Q + R = 180[/tex] --- angles in a triangle
Solve for P
[tex]P =180-Q-R[/tex]
[tex]P =180-96.4-58.4[/tex]
[tex]P =25.2[/tex]
