The 13th term of the given Arithmetic sequence is 38.
Arithmetic sequence:A list of integers with a distinct pattern is known as an arithmetic sequence. It is an arithmetic sequence if you can subtract any number in the sequence from the one before it and get a value that is either constant or always the same. Here the constant value is called a common difference.
The formula for the nth term of the Arithmetic sequence is given by
a[tex]_{n}[/tex] = a+(n-1)dHere we have
Arithmetic sequence: 2, 5, 8, 11,....
Where first term a = 2
And common difference d = term2 - term 1 = 5 - 2 = 3
As we know nth term of AP = a + (n-1)d
=> 13th term of AP = a + (13-1)d = a + 12d
From the give data, a = 2 and d = 3
=> 13th term = a + 12d
= 2 + 12(3)
= 2 + 36
= 38
Therefore,

Find the vertex of each of the following parabolas by averaging the x-intercepts. Then write each equation in graphing form. y=(x-3)(x-11)
The vertex of the parabola is at the point (7, 0) and since the vertex of this parabola is (7, 0), the equation of the parabola in graphing form is
y = a(x - 7)^2.The vertex of a parabola is the point on the graph where the parabola reaches its highest or lowest point. To find the vertex of the parabola y = (x - 3)(x - 11), you can average the x-intercepts of the parabola, which are the points where the parabola crosses the x-axis. The x-intercepts of this parabola are at x = 3 and x = 11, so the average of these two points is (3 + 11) / 2 = 7.
To write the equation of the parabola in graphing form, you can use the vertex form of a parabola, which is written as
y = a(x - h)^2 + kwhere (h, k) is the vertex of the parabola and a is a coefficient that determines the direction of the parabola (whether it opens upwards or downwards). Plugging in the values for the vertex and the y-coordinate of the vertex (which is 0), we get

2x^2+3x-6
(3x^2+6x-9)-(2x^2+3x-6)
x^2+3x-3
hopes this helps
Answer:
[tex]x^2 + 3x - 3[/tex]
Step-by-step explanation:
The perimeter of a triangle, can be calculated as, the sum of the sides.
So let's first assume the third side is a polynomial, and more specifically, a quadratic in the form: [tex]ax^2+bx+c[/tex]. This assumption is denoted from the fact that the perimeter only has terms up to the degree of 2, also known as x squared. The answer is also a quadratic, so it isn't an unreasonable assumption that if we add two quadratics (the ones given), and add one more quadratic, we should still have quadratic.
So, the sum of the three sides can be expressed as: [tex](x^2 + 2x - 1) + (x^2 + x - 5) + (ax^2 + bx + c)[/tex]
We can combine like terms to get:
[tex](x^2+x^2+ax^2)+(2x+x+bx)+(-1-5+c)[/tex]
Now from here, we can combine like terms (add coefficients):
[tex](2+a)x^2 + (3+b)x + (-6+c)[/tex]
From here, we simply set this equal to the given perimeter of: [tex]3x^2 + 6x-9[/tex], which gives us the equation:
[tex](2+a)x^2 + (3+b)x+(-6+c) = 3x^2 + 6x - 9[/tex]
Now from here, the coefficients need to correspond for both quadratics to be equal to each other, so that means that the following must be true:
[tex](2+a)=3\implies a = 1\\(3 + b) = 6\implies b = 3\\(-6 +c) = -9 \implies c = -3[/tex]
We now plug this into the quadratic standard form to get:
[tex]x^2 + 3x - 3[/tex]

The path of the airplane the astronauts are flying
in can be modeled using the function h(x) =
10000cos(0.0001x) + 20000 in which h indicates
the height in feet. What is the approximate period
of the wave?
Answer:
The approximate period of the wave representing the airplane's path is 0.9 hours.
Step-by-step explanation:
The period of a wave is the time it takes for one complete cycle of the wave to occur. In the case of the airplane's path, this would be the time it takes for the airplane to complete one full oscillation, or "up and down" motion.
To find the period of the wave, we need to determine the value of x that corresponds to one complete cycle of the wave. In this case, the wave is defined by the function h(x) = 10000cos(0.0001x) + 20000.
To find the period, we can use the formula T = 2π/ω, where T is the period, π is the mathematical constant pi, and ω is the angular frequency of the wave. The angular frequency is related to the frequency of the wave, which is the number of cycles per second.
In this case, the angular frequency is given by the coefficient of the x term in the function, which is 0.0001. Plugging this value into the formula above, we get T = 2π/0.0001 = 200000π seconds.
Since one cycle of the wave corresponds to one complete oscillation of the airplane, the period of the wave is approximately 200000π seconds. This is a very large number, so it is usually more useful to express the period in minutes or hours. To convert to minutes, we can divide the period by 60, which gives us a value of about 3334 minutes. To convert to hours, we can divide the period by 3600, which gives us a value of about 0.9 hours.
In summary, the approximate period of the wave representing the airplane's path is 0.9 hours.
Ask me any questions you may have!
The amount of time it takes for a wave to complete one full cycle is known as the wave's period. This would be the amount of time needed for the plane to perform one full oscillation, or “up and down” motion, in the case of the flight path.
What path airplane the astronaut's period of the wave?Finding the value of x that represents the wave's full cycle is necessary to calculate the wave's period. The equation h(x) = 10000cos(0.0001x) + 20000 in this instance defines the wave.
The formula T = 2/, where T is the period, is the mathematical constant pi, and is the wave's angular frequency, can be used to determine the period. The wave's frequency, or the number of cycles per second, and the angular frequency are connected.
We may convert the period to hours by dividing it by 3600, which gives us a number of approximately 0.9 hours.
Therefore, The wave that represents the course of the airplane has an approximate period of 0.9 hours.

a response variable y has correlation coefficient 0.3 with each of the predictors x1 and x2. however, these predictors are heavily correlated r x1x2
If the response variable y has a correlation coefficient of 0.3 with each of the predictors x1 and x2, it means that there is a weak linear relationship between y and both x1 and x2.
This means that as x1 and x2 increase or decrease, y is likely to change by a small amount. If x1 and x2 are heavily correlated, it means that there is a strong linear relationship between the two variables. This means that as x1 increases or decreases, x2 is likely to change by a large amount in the same direction. When two predictors are highly correlated, it can be difficult to determine the individual contribution of each predictor to the response variable y.
In this situation, it may be useful to use techniques such as multi-collinearity analysis or principal component analysis to understand the relationship between the predictors and the response variable better.

Answer:
The slope is same for both points.
Step-by-step explanation:
1st set of points: (1, 4) and (7, 2)
m = 2-4/7-1
m = -2/6
m = -1/3
2nd set of points: (7, 2) and (10, 1)
m = 1-2/10-7
m = -1/3
The slope is same for both points.
11 A fisherman wants to know how many fish there are in a lake. One day, he catches 50, marks them and puts them back. The next day he catches 80 fish. 20 of these fish have marks on them. Estimate the total number of fish in the lake.
The total number of fish in the lake would be = 60 fishes
What is total of a data set?The total of a data set is the addition of the various components that makes up a data set which gives a particular value.
On the first day the number of fish that was marked by the fisher man = 50 fishes.
On the second day the total amount of fishes that was caught = 80 fishes
The number of fishes that where among the 80 fishes that are marked= 20
Therefore the total amount of fishes in the lake = 80 - 20
= 60 fishes.

The positive integers greater than 3 are arranged in rows and columns as illustrated.
In which column is the number 5018?
A) 2
B) 4
C) 6
D) 5
E) 3
The rows and columns of the positive integers greater than three are as shown. And the number 5018 is found in the third column.
When performing a permutation test, you repeatedly rearrange one of the variables without affecting the other variable (s). From the given table, we can start with column 4. Here, each row has about 6 numbers. That is singular row has numbers from columns 1 to 6 and an even row from columns 7 to 2.
Then subtract 5018 by 3. We get 5018-3=5015.
Divide this by 6,
5015/6 = 836.
So 5018 is located in an even row from 7 to 2.
Therefore, 5018 is located in the 836th row and 3rd column.
So the required answer is E) 3.

A roller coaster ride holds a total of 48 passengers. The ratio of males to females on the ride is 5 : 7. Let x represent the number of males on the ride. Let y represent the number of females on the ride. Which two linear equations form a system that you can use to find the number of males and the number of females on the ride?
Answer:
5x + 7y = 48 (total number of passengers on the ride)
x + y = 48 (total number of males and females on the ride)
Step-by-step explanation:
To find the number of males and the number of females on the roller coaster ride, you can use the following two linear equations to form a system:
5x + 7y = 48 (total number of passengers on the ride)
x + y = 48 (total number of males and females on the ride)
The first equation states that the total number of passengers on the ride is equal to the sum of the number of males (5x) and the number of females (7y). The second equation states that the total number of males and females on the ride is equal to the sum of the number of males (x) and the number of females (y).
To solve this system, you can use algebraic techniques to eliminate one of the variables and solve for the other. For example, you could multiply the first equation by 5 and the second equation by 7, then subtract the two equations to eliminate the y variable:
5 * 5x + 7 * 7y = 5 * 48
7 * x + 7 * y = 7 * 48
25x + 49y = 240
49x + 49y = 336
24x = 336 - 240
24x = 96
x = 4
Substituting this value for x in the first equation, we can solve for y:
5 * 4 + 7 * y = 48
20 + 7 * y = 48
7 * y = 28
y = 4
Therefore, there are 4 males and 4 females on the roller coaster ride.
