Let the mechanical pencils of Jacqueline is x.

As Kimberly owns two less than three times the number of mechanical pencils Jacqueline owns.

⇒  The mechanical pencils of Kimberly are 3x - 2

As Julia owns three less mechanical pencils than Jacqueline.

⇒  The mechanical pencils of  Julia are x - 3

The three collectors own a total of 100 mechanical pencils.

⇒  x + (3x - 2) + (x - 3) = 100

                         5x - 5 = 100

                              5x = 105

                                x = 21

⇒ Mechanical pencils does Kimberly own are 3(21) - 2 = 63 - 2 = 61.

Hence, the number of mechanical pencils Kimberly own are 61.

The coordinate matrix of x relative to an orthonormal basis b in [tex]R^n[/tex] can be found by computing the inner product of x with each basis vector and representing these inner products as the entries of a column vector.

To find the coordinate matrix of x relative to an orthonormal basis b in R^n, we need to express x as a linear combination of the basis vectors in b. This can be done by computing the inner product (dot product) of x with each basis vector and representing these inner products as the entries of a column vector. The resulting vector is the coordinate matrix of x relative to the orthonormal basis b.

For example, let x be a vector in [tex]R^n\\[/tex], b = [tex]{b_1, b_2, ..., b_n}[/tex] be an orthonormal basis in R^n, and let A be the coordinate matrix of x relative to b. Then the entries of A are given by:

A = [tex]( x, b_1 , x, b_2 , ..., x, b_n )^T[/tex] where [tex]x, b_i[/tex] denotes the inner product of x and [tex]b_i[/tex].

It is important to note that the basis b must be orthonormal for the coordinate matrix to have this form, if the basis is not orthonormal, the process will be different.

Therefore , the solution to the given problem of triangle comes out to be the length MP is measured at 6 units.

Due to its three vertices and three sections, a component is a polygon. It has a simple geometric form. Triangle ABC refers to a triangle only with points A, B, and C. When components are not collinear, a singular plane and triangle are found. Triangles are regarded as polygons since they have three corners and a right side. The points where a triangle's three sides intersect are known as the triangle's corners. By compounding three triangle angles, one gets 180 degrees.

Here,

Triangle OMN is provided.

Now, OMN and OPQ are comparable. It follows that the side lengths are in proportion to one another. We can write:

=>OP = OM = PQ = MN

=>OM = PQ/MN in 12

=>(OP + PM)/12 = PQ/MN

Considering that -

=>PQ = MP + 2

=>12/(OP plus PM) = (MP plus 2)/MN

=>12MN equals (MP + 2)(OP + PM).

=>12 × 12 = (MP + 2)(MP + 12)

=>2 MP plus 12 MP plus 2 MP plus 24 = 144

=>(MP)² + 14(MP) - 120 = 0

We can write - if MP = x.

=>x² + 14x - 120 = 0

=>(x + 20)(x - 6) = 0

=>(x + 20) = 0 and (x - 6) = 0

x = - 20 and x = 6

There can be no negative lengths, hence x = 6

Consequently, the length MP is measured at 6 units.

Therefore , the solution to the given problem of triangle comes out to be the length MP is measured at 6 units.

The polynomial is x^4 - 8x^3 - 30x^2 + 144x + 405 = 0. The solution is obtained using the concept of bi-quadratic equation.

A 4-degree equation is a bi-quadratic equation.

Sometimes the phrase "bi-quadratic equation" is used as a substitute for the phrase "quartic equation." Such problems variable are straightforward to resolve because they can be reduced to quadratic equations in the variable x=z^2, which can then be solved for x using the quadratic formula and then in terms of the original variables by calculating the square roots.

Here,

We are given two roots of the bi-quadratic equation which are -3 and 7 - 2i.

Now, we will find the other two roots of the bi-quadratic equation by using the conjugates of the given roots.

In order to find the conjugate of complex numbers, we have to change the sign of the imaginary part.

So, we will get the conjugate of 7 - 2i = 7+2i

Thus, all the four roots of the bi-quadratic equation are -3, 7+2i, 7 - 2i and -3.

If two roots of an equation are given as a and b, then we can express the equation as (x-a) (x-b) = 0.

So, using this, we will form the equation with two imaginary roots 7+2i and 7−2i, which is given as:

[x-(7−2i)][x-(7+2i)]=0

⇒[x-7+2i][x-7-2i]=0

⇒[(x-7)+2i][(x-7)−2i]=0

Using the identity (a+b)(a-b)=a^2-b^2 , we get

(x-7)^2-(2i)^2=0

∵i=√-1

⇒(x-7)^2+(√-4)^2=0

⇒(x-7)^2+(-4)=0

⇒(x-7)^2 - 4=0

Now we will form the equation with roots -3 and -3, which is

[x-(-3)][x-(-3)]=0

⇒(x+3)^2=0

Finally, we will now find the product of these two quadratic equations to get the required bi-quadratic equation

⇒[(x-7)^2 - 4] [(x+3)^2]=0

⇒[x^2 + 49 - 14x -4] [x^2 + 9 + 6x]=0

⇒[x^2 + 45 - 14x] [x^2 + 9 + 6x]=0

⇒x^4 + 9x^2 + 6x^3 + 45x^2 + 405 + 270x - 14x^3 - 126x - 84x^2 = 0

⇒x^4 - 8x^3 - 30x^2 + 144x + 405 = 0

Hence, the required polynomial is x^4 - 8x^3 - 30x^2 + 144x + 405 = 0

When we compare ratios, equivalent ratios are the ones that don't change. In order to determine whether or not different ratios are equivalent, we compare them side by side. An example makes it clear that the ratios 1:2 and 2:4 are equivalent. With the aid of division and multiplication, we can determine the two equivalent ratios.

In order to create a ratio that is equal to one that is already given, we must multiply or divide the given ratio's two terms by a non-zero number.

1 cup of flour = 1/2 cup of water

4 cups of flour = 1/2 × 4

The given expression is:

(23^20-53^19)/(-9)^9

This is a mathematical expression that involves multiple operations. The first step is to understand the order of operations, or PEMDAS (Parentheses, Exponents, Multiplication and Division, and Addition and Subtraction)

Parentheses: The expression does not contain any parentheses, so we can move on to the next step.

Exponents: The first term, 23^20, contains an exponent. The exponent operator (^) has higher precedence than the multiplication operator (), so we will simplify the exponent first. 3^20 is equal to 3 raised to the power of 20, which is equal to 3 * 3 * 3 * ... * 3 (20 times) = 59,049. Therefore, the first term is now 2 * 59,049.

The second term 5*3^19 also contains an exponent, so we simplify it in the same way as the first term. 3^19 is equal to 3 * 3 * 3 * ... * 3 (19 times) = 7,29,043. Therefore, the second term is now 5 * 7,29,043.

Multiplication and Division: After simplifying the exponents, we can see that the expression contains both multiplication and division. Since division has the same precedence as multiplication, we can simplify the expression from left to right.

The first term 2 * 59,049 is the product of 2 and 59,049. Multiplying these two numbers gives us 118,098.

The second term 5 * 7,29,043 is the product of 5 and 7,29,043. Multiplying these two numbers gives us 36,45,215.

The third term is the division of two terms. We have (23^20-53^19) / (-9)^9

Subtraction : Now we have the subtraction of two terms (118,098 - 36,45,215)

Now we have the division of two terms (-35,27,117) / (-9)^9. In this step, we are dividing the subtraction with -9 raised to the power of 9

The final step is to simplify the division. -9^9 is equal to -9 * -9 * -9 * -9 * -9 * -9 * -9 * -9 * -9 = -3486784401.

So the final expression is -35,27,117/-3486784401.
