The value of the quadratic equation is A = ( 9x + 10 ) ( x - 2 )

A quadratic equation is a second-order polynomial equation in a single variable x , ax² + bx + c=0. with a ≠ 0. Because it is a second-order polynomial equation, the fundamental theorem of algebra guarantees that it has at least one solution. The solution may be real or complex.

The roots of the quadratic equations are

x = [ -b ± √ ( b² - 4ac ) ] / ( 2a )

where ( b² - 4ac ) is the discriminant

when ( b² - 4ac ) is positive, we get two real solutions

when discriminant is zero we get just one real solution (both answers are the same)

when discriminant is negative we get a pair of complex solutions

Given data ,

Let the quadratic equation be represented as A

Now , the value of A is

A = 9x² - 8x - 20   be equation (1)

On simplifying the equation , we get

A = 9x² - 18x + 10x - 20

On factorizing the equation , we get

A = 9x ( x - 2 ) + 10 ( x - 2 )

Taking the common factors in the equation , we get

A = ( 9x + 10 ) ( x - 2 )

So , when A = 0

( 9x + 10 ) = 0

x = -10/9

And , when ( x - 2 ) = 0

x = 2

Hence , the quadratic equation is A = ( 9x + 10 ) ( x - 2 )

The diagonals of a parallelogram are equal in length if and only if the parallelogram is a rectangle. The sum of squares of diagonals is equal to the sum of squares of sides.

We should consider a parallelogram shape that has sides named as and .

a. The corner to corner lines of the parallelogram can be marked as and . These two inclining lines cross each other at the focal point of the parallelogram, isolating each other into halves. This implies that the two inclining lines and have a similar length.

b. Assuming the inclining lines of the parallelogram have similar length, this implies that the parallelogram is really a square shape. This is on the grounds that in a square shape, every one of the sides are equivalent long. Then again, on the off chance that the parallelogram is a square shape, its inclining lines should have a similar length.

c. We can utilize the Pythagorean hypothesis to show that the amount of the squares of the lengths of the slanting lines is equivalent to the amount of the squares of the lengths of the sides. The Pythagorean hypothesis expresses that in a right triangle, the amount of the squares of the two more limited sides is equivalent to the square of the length of the longest side (the hypotenuse). On the off chance that we view at the parallelogram as two nearby right triangles, we can apply the Pythagorean hypothesis to every triangle. This gives us two conditions, and when we add these two conditions, we observe that the amount of the squares of the lengths of the inclining lines is equivalent to the amount of the squares of the lengths of the sides.

b) The zeros are given as follows: x = 30 and x = 50.

c) The function is defined as follows: y = 0.03x² - 2.4x + 45.

The quadratic function with roots x* and x** is given by the equation presented as follows:

y = a(x - x*)(x - x**)

The roots = zeros are the values of x for which the graph of the function crosses the x-axis, hence:

x* = 30, x* = 50.

Then the function is:

y = a(x - 30)(x - 50)

y = a(x² - 80x + 1500).

When x = 0, y = 45, hence the leading coefficient a is obtained as follows:

1500a = 45

a = 45/1500

a = 0.03.

Hence the definition of the function is given as follows:

The assumed line's and direction's parametric equation is x = 5 + t; y = -1; z = 3 -2t

How can the parametric equation be found?

The absence of points and lines renders the question insufficient.

I will therefore utilize the following presumptive parameters:

As the line traverses: (5, -1, 3)

The direction is  ~v = <1, 0, -2>

The parametric equation of the line is represented as:

r<x,y,z> = Line + t<direction>

This gives

r<x,y,z> = (5, -1, 3) + t<1, 0, -2>

Express the equation in terms of x, y and z

x = 5 + t * 1

y = -1 + 0 * t

z = 3 -2 * t

Solve the equations

x = 5 + t

y = -1

z = 3 -2t

Consequently, the assumed line's and direction's parametric equation is x = 5 + t; y = -1; z = 3 -2t

Step-by-step explanation:

Step-by-step explanation: The range of the function is the set of all its output values. To find the range of f(a) = 5 + 1/2a when the domain is (0, 4, 6), we can substitute these values into the function and see what the output is:

f(0) = 5 + 1/2 * 0 = 5

f(4) = 5 + 1/2 * 4 = 7

f(6) = 5 + 1/2 * 6 = 8

So the range of f(a) is the set of values {5, 7, 8}.

The number of peaks, symmetry, tendency to skew, and homogeneity of a distribution are all indicators of its shape.

Explain about the shape of the distribution?

There are two types of data item distributions: symmetric and asymmetric. The "normal distribution" and the "skewed distribution" are two prevalent illustrations of both symmetry and asymmetry. The distribution's two halves are mirror images of one another in a symmetrical distribution.

The number of peaks, the presence of symmetry, the propensity to skew, and the homogeneity of a distribution all help to explain its shape. (Graphs with skewed distributions show a greater number of points on one side than the other.) PEAKS: Graphs frequently show maximums or peaks in a certain area.

Either a normal distribution or a normal curve. When dealing with such a distribution, the mean should be reported.

A histogram is a graph that represents the frequency distribution of a set of continuous data. It is similar to a bar graph, but the bars are adjacent to each other and there are no spaces between the bars.

Shape of the distribution:

The shape of the distribution is right-skewed, which means that the majority of the data is concentrated on the left side of the distribution and there is a long tail of data points on the right side.
