End behavior of a function f defines the behavior of the function's graph at the "ends" of the x-axis. In other words, the end behavior of a function explains the graph's trend when we look to the right end of the x-axis (as x approaches +∞ ) and to the left end of the x-axis (as x approaches −∞ ).
What is function?A function is an equation with just one solution for y for every x. A function produces exactly one output for each input of a certain type. Instead of y, it is usual to call a function f(x) or g(x). f(2) indicates that we should discover our function's value when x equals 2. Example. A function is a type of rule that produces one output for one input. Alex Federspiel provided the image. y=x2 is an example of this. If you enter anything for x, you will only get one output for y. Because x represents the input value, we may say that y is a function of x.

What is the y-intercept of 5x+4y=−40 ?
A.(8,−10)
B.(0,−10)
C.(0,8)
D.(−10,0)
Answers
Answer:
B
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Given
5x + 4y = - 40 ( subtract 5x from both sides )
4y = - 5x - 40 ( divide all terms by 4 )
y = - \(\frac{5}{4}\) x - 10 ← in slope- intercept form
with y- intercept c = - 10 ⇒ (0, - 10 ) → B
Step-by-step explanation:
To find the y intercept of the line we must first write the equation in standard form which is
y = mx + c
where
m is the slope
c is the y intercept
So we have
5x + 4y = - 40
4y = -5x - 40
Divide both sides by 4
We have the equation as
\(y = - \frac{5}{4} x - 10\)
From the question the y intercept is - 10
We have the final answer as

Step-by-step explanation:
so b = 4
and the slope is rise over run = 5/2
Answer:
D) \(y=\frac{5}{2}x+4\)
Step-by-step explanation:
The line equation of a line is:
\(y=mx+b\) with m being the slope and b being the y-intercept.
We can see from the graph that the y-intercept is 4, as that's where the line intercepts the y-axis, and when x=0.
To find the slope, we first need to pick 2 points: (0,4) and (2,9).
The formula for slope is:
\(\frac{rise}{run}\)
The rise is how many units you go up/down from one point to another. The run is how many units you go left/right from one point to another.
We can see that we go up 5 units and we go right 2 units. This means our slope is 5/2.
The completed line equation is:
\(y=\frac{5}{2}x+4\), which means D is the correct option.

Answers
Answer:
7.5 yards
Step-by-step explanation:
Since the area of a triangle is found by the equation: \(\frac{bh }{2}\), in which b=base h=height, and \(bh\) is base times height, we can work backward from the value of the area to find the height of the park
Start by multiplying 7500 by 2. From this, you get 15000.
Now for the second step, you have to divide 15000 by 2000 in order to determine the height of the triangle. this value comes out to 7.5.
This means that the values of the equation are b=2000 and h=7.5 \(\frac{2000(7.5)}{2}\)
To double-check, we multiply 2000 by 7.5. and divide that value by 2. This gives us the original area of 7500
This means that the height of the park is 7.5 yards
the early income of a girl is rupees 150000 the tax free allowance is rupees 100000 if the text for the first rupees 20000 is 12% and for the remaining is 15% how much tax should she pay in a year ?
Answers
Answer:
Rs 6900
Step-by-step explanation:
To calculate the tax amount the girl should pay in a year, we need to determine the taxable income and then apply the corresponding tax rates.
The taxable income is calculated by subtracting the tax-free allowance from the girl's early income:
Taxable Income = Early Income - Tax-Free Allowance
Taxable Income = 150,000 - 100,000
Taxable Income = 50,000
Now, we can calculate the tax amount based on the given tax rates:
For the first 20,000 rupees, the tax rate is 12%:
Tax on First 20,000 = 20,000 * 0.12
Tax on First 20,000 = 2,400
For the remaining taxable income (30,000 rupees), the tax rate is 15%:
Tax on Remaining 30,000 = 30,000 * 0.15
Tax on Remaining 30,000 = 4,500
Finally, we add the two tax amounts to get the total tax she should pay in a year:
Total Tax = Tax on First 20,000 + Tax on Remaining 30,000
Total Tax = 2,400 + 4,500
Total Tax = 6,900
Therefore, the girl should pay 6,900 rupees in tax in a year.

Simplify each trigonometric expression.
cos ²θ-1
Answers
Simplification of trigonometric expression cos²θ - 1 = cos(2θ) - cos²θ.
For simplifying the trigonometric expression cos²θ - 1, we can use the Pythagorean Identity.
The Pythagorean Identity states that cos²θ + sin²θ = 1.
Now, let's rewrite the expression using the Pythagorean Identity:
cos²θ - 1 = cos²θ - sin²θ + sin²θ - 1
Next, we can group the terms together:
cos²θ - sin²θ + sin²θ - 1 = (cos²θ - sin²θ) + (sin²θ - 1)
Now, let's simplify each group:
Group 1: cos²θ - sin²θ = cos(2θ) [using the double angle formula for cosine]
Group 2: sin²θ - 1 = -cos²θ [using the Pythagorean Identity sin²θ = 1 - cos²θ]
Therefore, the simplified expression is:
cos²θ - 1 = cos(2θ) - cos²θ

A histogram is a basic statistical tool that graphically shows the frequency or number of observations of a particular value or within a specified group.
A histogram is a chart that displays data by dividing it into intervals, or "bins," and then counting how many data points fall into each bin. The x-axis of a histogram represents the range of values being analyzed, while the y-axis represents the frequency or count of values that fall within each bin.
Histograms are commonly used to illustrate the distribution of data. They provide a visual representation of the central tendency, variability, and shape of the data. In particular, histograms can reveal patterns in the data such as skewness, outliers, or gaps.
Histograms are frequently used in data analysis across many fields, including finance, biology, psychology, and engineering. They can be created using software programs such as Microsoft Excel, R, Python, or MATLAB.

what is y=6x^2 +96x +388 in vertex form?
please show work
Answers
Answer:
y = 6(x + 8)² + 4
Step-by-step explanation:
The equation of a parabola in vertex form is
y = a(x - h)² + k
where (h, k) are the coordinates of the vertex and a is a multiplier
Using the method of completing the square.
y = 6x² + 96x + 388
The coefficient of the x² term must be 1, so
factor out 6 from 6x² + 96x
y = 6(x² + 16x ) + 388
To complete the square
add/subtract (half the coefficient of the x- term)² to x² + 16x
y = 6(x² + 2(8)x + 64 - 64) + 388
= 6(x + 8)² - 384 + 388
y = 6(x + 8)² + 4 ← in vertex form

Answers
Both M and S in sexagesimal notation = 3600D.
Here converting 'D' into minutes.
We know that a degree is made up of 60 minutes.
so multiply D with 60 we get
⇒ D x 60 = M
Now convert 'M' into seconds.
Again, there are 60 seconds in a minute,
so multiply M with 60 we get,
⇒ M x 60 = S
Simplify this equation by substituting D x 60 for M,
⇒D x 60 x 60 = S
Simplifying further, we get,
⇒ 3600D = S
Hence, 3600D is equal to both M and S in sexagesimal notation.

If A is a 9x6 matrix, what is the largest possible dimension of the row space of A? If A is a 6x9 matrix, what is the largest possible dimension of the row space of A? Explain.
Answers
If A has rank 6, then it has 6 linearly independent rows and its row space has dimension 6. If the rank of A is less than 6, then the dimension of the row space will be less than 6.
The row space of a matrix is the span of its row vectors. Therefore, the dimension of the row space is equal to the number of linearly independent rows of the matrix.
For a 9x6 matrix A, the largest possible dimension of the row space is 6. This is because there can be at most 6 linearly independent rows in a 9x6 matrix. If there were more than 6 linearly independent rows, then the matrix would have rank greater than 6, which is impossible since the maximum rank of a 9x6 matrix is 6.
For a 6x9 matrix A, the largest possible dimension of the row space is also 6. This is because the number of linearly independent rows cannot exceed the number of columns in the matrix.
Therefore, if A has rank 6, then it has 6 linearly independent rows and its row space has dimension 6.
However, if the rank of A is less than 6, then the dimension of the row space will be less than 6.
