What is arithmetic progression?A sequence in which the next term in the sequence is obtained by adding a constant to each term is known as an arithmetic progression. The common difference is the added constant. It is a succession to such an extent that the contrast between any two sequential terms in the grouping is dependably a consistent.
Consider the terms of an arithmetic progression sequence as n1, n2, n3, n.
Given a series 29, 38, 47, ….
for an AP aₙ = a₁ + (n - 1)d
where a₁ = first term of AP
n = number of terms, and d = difference between the terms
here d = 9, n = 11 and a₁ = 29
a₁₁ = 29 + (11 - 1)x9
a₁₁ = 29 + 10 x 9
a₁₁ = 119
Hence the term is 119.

Step-by-step explanation:
Given is the piecewise function.
It has three different pieces.
The first piecef(x) = 2, with x ≤ -2Plot the point (-2,2) and draw a horizontal line to the left from this point
The second piecef(x) = 1/2x + 3, at the interval -2<x≤1Plot two border points at x = -2 and x = 1:
f(-2) = 1/2*(-2) + 3 = 2, point (-2, 2)and
f(1) = 1/2*1 + 3 = 3.5, point (1, 3.5)Connect these two points with a line segment
The third piecef(x) = -7/8x + 35/8, at x > 1Plot two points at x = 1 and x = 5 (5 is an example, it could be anything > 1)
f(1) = -7/8*1 + 35/8 = 28/8 = 3.5and
f(5) = -7/8*5 + 35/8 = 0Connect the two points (1, 3.5) and (5, 0) and extend the line to the right
Remember the point (-2,2) belongs to the first piece and the point (1, 3.5) belongs to the second piece.

Malik solved this system of equations.
2 x + 4 y = 24. 5 x + y = 15.
As the first step, he decided to solve for x in the first equation because it has a small, even number for the coefficient. Jill told him there was a more efficient way. What reason can Jill give for her statement?
The variable y in the second equation has a coefficient of one so there will be fewer steps to the solution.
The variable x in the second equation has a coefficient of 5 so it will be easy to divide 15 by 5.
The variable y in the first equation is divisible by 2 so it will be the most efficient way to start.
The variable y in the first equation has a larger even number. When dividing by 4, the solution will be a smaller number.
The reason Jill give for her statement is that the variable y in the second equation has a coefficient of one so there will be fewer steps to the solution. Hence, option A is the correct statement.
What is a system of equations?A system of equations is two or more equations that can be solved to get a unique solution. the power of the equation must be in one degree.
System of equations
Given the simultaneous equation;
2x+4y=24
5x+y=15
The best way to solve this kind of system of equation is by the substitution method.
Then To do that in an easy way, we can locate which of the variables in the equations has a coefficient of 1.
From the second equation, we can see that the variable "y' has a coefficient of 1.
Therefore, the reason that Jill can give for her statement is that the variable y in the second equation has a coefficient of one so there will be fewer steps to the solution.
Hence, option A is the correct statement.

Hi can anyone please help me with this problem, I’d really appreciate it
We can start this equation off by noticing the fact that this is a linear equation, which we can write in the form of: [tex]mx+b[/tex]. We can plug in our x values and y values given. I am going to start on the second line:
We plug in the given point: [tex](0,-3.2)[/tex].
[tex]-3.2=m(0)+b\\-3.2=b[/tex]
We can also plug in the point [tex](4,0)[/tex] to get:
[tex]0 = m(4) -3.2[/tex]
We get [tex]m = 0.8[/tex]
Therefore, our equation for the SECOND line is:
[tex]y = 0.8m - 3.2[/tex]
Hope that this helps you do the first line.

The slope of the line below is 5. Which of the following is the point-slope form
of the line?
(-1,3)
5
A. y + 3 = -5(x - 1)
B. y + 3 = 5(x - 1)
C. y - 3 = 5(x+1)
D. Y-3 = -5(x + 1)
The point-slope form of the line in the graph is y-3 = 5(x+1). The correct option is C.
What is the point-slope form of the line?The point-slope form of the line is y-y₁ = m( x-x₁)
Here, m is the slope of the line.
The graph given in the question has a slope of 5
It passes through the point ( -1,3)
The point slope form of the line is
y - 3 = 5 ( x - (-1))
y-3 = 5(x+1)
This is represented by option C.

Ms. Mwanted to estimate the height of the Republic Plaza building in downtown Denver. She has an app on
her phone that will measure an angle of elevation. She determined she was 100 feet from the base of the
building. She held her phone (with the app) at eye level (about 5 feet off the ground) and measured the angle
of elevation to the top of the building to be 82°. What is the height of the building to the nearest foot?
Answer:
The height of the bullding is 717 ft
Step-by-step explanation:
Right Triangles
The trigonometric ratios (sine, cosine, tangent, etc.) are defined as relations between the triangle's side lengths.
The tangent ratio for an internal angle A is:
[tex]\displaystyle \tan A=\frac{\text{opposite leg}}{\text{adjacent leg}}[/tex]
The image below shows the situation where Ms. M wanted to estimate the height of the Republic Plaza building in downtown Denver.
The angle A is given by his phone's app as A= 82° and the distance from her location and the building is 100 ft. The angle formed by the building and the ground is 90°, thus the tangent ratio must be satisfied. The distance h is the opposite leg to angle A and 100 ft is the adjacent leg, thus:
[tex]\displaystyle \tan 82^\circ=\frac{h}{100}[/tex]
Solving for h:
[tex]h = 100\tan 82^\circ[/tex]
Computing:
h = 711.5 ft
We must add the height of Ms, M's eyes. The height of the building is
711.5 ft + 5 ft = 716.5 ft
The height of the building is 717 ft
