The value of x such that the vertices 3x + 10 and x + 60 are equal is 25
What are vertices?Vertices are the endpoints or corners of a shape (such as triangle, square, rectangle and related shapes)
How to determine the value of x?The two vertices are given as:
3x + 10 and x + 60
The condition on the two vertices are not given.
So, we assume that the vertices are equal (as in the base angles of an isosceles triangle)
So, we have the following equation
3x + 10 = x + 60
Subtract x from both sides of the equation
2x + 10 = 60
Subtract 10 from both sides of the equation
2x = 50
Divide both sides of the equation by 2
x = 50/2
Evaluate the quotient
x = 25
Hence, the value of x such that the vertices 3x + 10 and x + 60 are equal is 25

2*3^20-5*3^19/(-9)^9
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.
The expression is a very large negative number divided by a very large negative number, which results in a very small positive number.

Answer: To calculate the percentage decrease in the number of available seats, we can use the following formula:
(original value - new value) / original value * 100
In this case, the original value is 125 (the number of available seats before the reduction) and the new value is 93 (the number of available seats after the reduction). Plugging these values into the formula:
(125 - 93) / 125 * 100 = 32 / 125 * 100 = 0.256 * 100 = 25.6
So, there is a 25.6% decrease in the number of available seats.

A polynomial of the fourth degree has both non-real roots and real roots with multiplicities.
If two of the roots are -3 and 7 - 2i, identify this polynomial.
The polynomial is x^4 - 8x^3 - 30x^2 + 144x + 405 = 0. The solution is obtained using the concept of bi-quadratic equation.
What is 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

drawn to scale. State your answer in simplest radical form, if necessary.
Therefore , the solution to the given problem of triangle comes out to be the length MP is measured at 6 units.
Explain the triangle.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 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.

Find a spot at a whiteboard and complete the following:
There are two malls that open at the same time.
The number of people in Mall A is modeled by -t² +9t + 36,
and the number of people in Mall B is modeled by - t² + 11t + 12,
where t represents the number of hours since the mall opened.
A) Write an expression that models how many more people are in Mall A than Mall B at time t.
B) How many people are in Mall A when t = 3 hours?
On solving the provided question, we can say that we have two quadratic equations; t² +9t + 36 > t² + 11t + 12 => t>12
What is quadratic equation?A quadratic equation is x ax2+bx+c=0, which is a quadratic polynomial in a single variable. a 0. The Fundamental Theorem of Algebra ensures that it has at least one solution since this polynomial is of second order. Solutions may be simple or complicated. An equation that is quadratic is a quadratic equation. This indicates that it has at least one word that has to be squared. The formula "ax2 + bx + c = 0" is one of the often used solutions for quadratic equations. where are numerical coefficients or constants a, b, and c. where the variable "X" is unidentified.
