The equation is unchanged when you replace x with --x AND y with -y.

Hence, according to the above hypothesis, our equation is origin symmetry.

Equation graphs may be symmetric with regard to the origin or with respect to one of the coordinate axes.

If the Cartesian plane were folded along the -axis, the area of the graph above the x-axis and the area below the x-axis would coincide. This is known as symmetry with regard to the -axis.

Similar concepts apply to symmetry with regard to the y-axis or the origin.

For the given coordinates, the equation of line is y = 1, The coordinates of foot of perpendicular will be (0, 5)

Assume that ax + by + c = 0. is a continuous line. If a perpendicular line is drawn from any point on the plane to the provided straight line, the intersection of the two lines is referred to as the foot of the matching perpendicular.

Because a perpendicular line is created from point P to the y-axis, the distance between its intersection with the x-z plane remains constant.

Given,

the points of line are - (1, 1) and (5, 5).

equation of line = (y - yo) = m (x - xo)

⇒ y - 1 = [tex]\frac{5 - 1}{5 - 1}[/tex] (x - 1)

An equation is a  mathematical statement that is made up of two expressions connected by an equal sign.  In its simplest form in algebra, the definition of an equation is a mathematical statement that shows that two mathematical expressions are equal. For instance, 3x + 5 = 14 is an equation, in which 3x + 5 and 14 are two expressions separated by an 'equal' sign.

here, we have,

The perimeter of a rectangle is 40 cm. The length is 14 cm.

Let x = width of the rectangle.

Ravi says he can find the width using the equation 2(x + 14) = 40.

Fran says she can find the width using the equation 2x + 28 = 40.

now, we get,

1. Divide both sides by 2

 2(x+14) = 40

 x+14 = 20

2. Isolate the x term by subtracting 14 from both sides

3. x = 6. The width of the triangle is 6 cm.

4. Isolate the x term by subtracting 28 from both sides

 2x + 28 = 40

 2x = 12

5. Divide both sides by 2

6. x = 6

7. The two equations have the same solution, because by the distributive rule, 2(x+14) = 2x+28.

Let x = amount of mL of the 62% acid solution

Let y = amount in mL of the 19% acid solution

We know the total mL of the mixture of the two solutions is 600 mL,

The mean/standard error of the sampling distribution of the proportion is 0.0111.

Its root-mean The square root of the mean of the squares of all the values in a series calculated from the arithmetic mean is the square deviation, also referred to as the standard deviation and denoted by the symbol.

The standard deviation reveals the degree of data dispersion. It expresses how far away from the mean each observed value is.

Almost 95% of the values in any distribution will be within two standard deviations of the mean. The degree of data dispersion from the mean is described by the term "standard deviation" (or " σ").

The data tend to cluster around the mean when the standard deviation is low; when it is high, the data are more dispersed.

The formula to calculate the standard error of sampling distribution of sample proportion is:

It is given that the bank believes that 8% of people who receive loans will not make payments on time. That is,

Step-by-step explanation:

A solution to the system is where the two equations intersect.

looking at the graph, we see that the intersection point is between x= 3 and 4, and Y = 2 and 3.

Answer:

(3.5, 2.25)

Step-by-step explanation:

To find the coordinate of the solution to the system of linear equations −3x + 2y = −6 and y = -1/2x + 4, we need to solve the system. One method to do this is substitution. We can solve one of the equations for y, then substitute the expression for y into the other equation. This will give us an equation in terms of x, which we can then solve for x. Then, we can substitute the value of x back into one of the equations to find the corresponding value of y.

Using substitution, we can solve the system as follows:

y = -1/2x + 4

-3x + 2y = -6

Substitute y = -1/2x + 4 into -3x + 2y = -6:

-3x + 2(-1/2x + 4) = -6

-3x + (-x + 8) = -6

-4x + 8 = -6

-4x = -14

x = 3.5

Substitute x = 3.5 into y = -1/2x + 4:

y = -1/2(3.5) + 4

y = 2.25

Therefore, the solution to the system is approximately (3.5, 2.25).

"The function is increasing in the interval (-2.5,∞)".

To determine whether the function is increasing or decreasing we are going to use the derivative test.

f(x) = x² + 5x + 6

f'(x) = 0

2x + 5 = 0

x = -5/2

Intervals associated with this point are  (-∞,-2.5) and (-2.5,∞)

Now by checking in the interval  (-∞,-2.5)  at a point, let's say -3

Then,

f'(-3) = -1 so function is decreasing over this interval.

Now by checking in the interval  (-2.5,∞)  at a point, let's say 2

Then,

f'(2) = 1 so function is increasing over this interval.

The function f(x,y) is defined for all (x,y) pairs that lie within the region d, which is bounded by the parabolas y= 2x2 and y= 1 x2. It returns the product of x and 2 to the power of y.

The function f(x,y) is a two-variable function defined on the region d, which is bounded by the parabolas y= 2x2 and y= 1 x2. In order to calculate the output of this function, we must first identify the values of x and y that lie within the region d. We can do this by graphing both parabolas and finding the intersection point, which is when x=1 and y=2. This tells us that any (x,y) pairs with x<1 and y<2 will be within the region d. Now that we have identified the region, we can calculate the output of the function by multiplying x and 2 to the power of y. For example, if x=0.5 and y=1, then f(x,y)= 0.52 = 0.25.

The minimum degree of a Taylor polynomial required to calculate to 3 decimal places depends on the complexity of the function being approximated.

A Taylor polynomial is a way of approximating a function with a polynomial. The polynomial is built based on the function's value and its derivatives at a specific point.

To calculate a Taylor polynomial to 3 decimal places, the degree of the polynomial required depends on the complexity of the function and the desired accuracy.

If the function is smooth, with no sudden changes, a lower degree polynomial may be sufficient to approximate the function to 3 decimal places.

A general rule is to use a polynomial of degree at least two times the number of decimal places desired. So, for 3 decimal places, a polynomial of degree 6 or higher is required.

However, it is important to note that the minimum degree required can be determined by experimenting with different degrees of polynomials and checking the accuracy of the approximation.

Her rent is now = 640 per month

Since, After a year her rent will increase by 15 %
