- Find area of a rectangle if the length is
represented by 8x³y² and the width is
represented by 3x²yº.
Answer:
The area of the rectangle is 24x^5 y^2.
Step-by-step explanation:
To find the area of a rectangle when the length is represented by 8x³y² and the width is represented by 3x²yº, you need to multiply the length by the width.
8x³y² represents the length and 3x²yº represents the width.
Therefore, the area (A) of the rectangle can be calculated as:
A = length x width
A = 8x³y² x 3x²yº
To simplify this expression, you can use the laws of exponents:
A = 8x³y² x 3x²y°
A = 8 x 3 x x³ x x² x y² x yº
A = 24x^(3+2) y^(2+0)
Simplifying further:
A = 24x^5 y^2
Therefore, the area of the rectangle is 24x^5 y^2.
Answer:
I'm going to make it more simple for you so you don't have to read his book (no offence to that guy)
the area of the rectangle is 24x^5 y^2.
Find x
a(x+2) = b(x-1)
For expression a(x+2) = b(x-1), x will be (-b - 2a)/(a - b).
What exactly are expressions?
In mathematics, an expression is a combination of numbers, variables, operators, and/or functions that can be evaluated to produce a numerical value. Expressions can range from simple calculations involving only arithmetic operations such as addition, subtraction, multiplication, and division, to more complex combinations of algebraic expressions and functions.
Now,
To solve for x in the equation a(x+2) = b(x-1), we can use algebraic manipulation:
a(x+2) = b(x-1)
ax + 2a = bx - b [distribute the terms]
ax - bx = -b - 2a [subtract bx and 2a from both sides]
x(a - b) = -b - 2a [factor out x]
x = (-b - 2a)/(a - b)
Therefore,
x = (-b - 2a)/(a - b).

Therefore, the length of LM is 85.5.
What is length?Length is a measure of the size or extent of an object or a distance between two points. It refers to the longest dimension of an object or the distance between two points in space, typically measured in units such as inches, centimeters, meters, or miles. In mathematics, length is also used to describe the size of a line segment or a curve, which can be measured using various techniques such as Euclidean distance, arc length, or fractal dimension. Length is an important concept in many fields, including physics, engineering, geometry, and statistics.
Since LM is the midsegment of ABCD, it is parallel to both AB and DC, and its length is equal to the average of the lengths of AB and DC.
The length of LM can be found using the formula:
[tex]LM = (AB + DC) / 2[/tex]
Substituting the given values, we get:
[tex]LM = (46 + 125) / 2[/tex]
[tex]LM = 171 / 2[/tex]

S is not a basis for R3 because: c. S is linearly dependent and does not span R3.
What's basis for a vector spaceA basis for a vector space is a set of vectors that are linearly independent and span the space.
Let's check if S = {(1, 1, 1), (0,1,1), (1,0,1), (0, 0, 0)} satisfies this definition of the basis or not.
Here, we have to find if the set is linearly dependent or not. If the set is linearly dependent, then it can't be a basis. To check the linearity of the set, we will set the equation for the linear combination of vectors of set S.
Then α1(1, 1, 1) + α2(0,1,1) + α3(1,0,1) + α4(0, 0, 0) = 0
For the above equation to hold true, α1 + α3 = 0α1 + α2 = 0α1 + α3 = 0
By solving the above equations, we get
α1 = -α3α2 = -α1α4 = 0
The above equation shows that α4 = 0 means there is always a trivial solution which makes it linearly dependent.
Therefore, it is not a basis.

Give a brief account on circle.A circle is a shape consisting of all points in the plane that are at a specified distance from a specified point (center). Correspondingly, it is a curve drawn by points moving in the plane at a constant distance from a point. The distance from any point of the circle to the center is called the radius. Normally the radius should be a positive number.
Specifically, a circle is a simple closed curve that divides a plane into two regions inside and outside. In everyday use, the term "circle" can be used interchangeably to refer to the entire shape, including the boundary or interior of the shape. In strict technical usage the circle is just the boundary and the whole figure is called the disk.
In ΔOCA;
OC = OA [Radius of circle]
So, m∠OCA = m∠OAC
y = m∠OCA
y = m∠OAC
Similarly in ΔAOB;
m∠OAB = 2x

A box contains 7 plain pencils and 1 pen. A second box contains 3 color pencils and 3 crayons. One item from
each box is chosen at random. What is the probability that a pen from the first box and a crayon from the
second box are selected?
Write your answer as a fraction in simplest form.
The probability of selecting a pen from the first box is 1/8 (since there is only 1 pen out of 8 items in the box). The probability of selecting a crayon from the second box is 3/6 (since there are 3 crayons out of 6 items in the box).
To find the probability of both events happening together, we multiply the probabilities:
P(pen and crayon) = P(pen) x P(crayon)
P(pen and crayon) = (1/8) x (3/6)
Simplifying the fraction 3/6 to 1/2:
P(pen and crayon) = (1/8) x (1/2)
Multiplying the numerators and denominators:
P(pen and crayon) = 1/16
Therefore, the probability of selecting a pen from the first box and a crayon from the second box is 1/16.

Given: -6x < 36. Choose the solution set. {x | x < 6} {x | x > 6} {x | x < -6} {x | x > -6}
To solve the inequality -6x < 36, we need to isolate x on one side of the inequality sign. We can do this by dividing both sides of the inequality by -6, remembering to reverse the inequality sign because we are dividing by a negative number:
-6x < 36
x > -6
Therefore, the solution set for the inequality is {x | x > -6}.

5. Using complete sentences, describe how the variable h and the variable k of the general formula for a cube root function effects the graph. The general formula is
y=a³√√x-h+k
Answer: The variables h and k in the general formula for a cube root function affect the graph by causing a horizontal and vertical shift, respectively. The value of h determines the horizontal position of the graph by shifting it to the right or left along the x-axis. If h is positive, the graph will shift to the right, and if h is negative, the graph will shift to the left. On the other hand, the value of k determines the vertical position of the graph by shifting it up or down along the y-axis. If k is positive, the graph will shift upward, and if k is negative, the graph will shift downward. It is important to note that these shifts do not affect the shape of the graph, only its position on the coordinate plane. Therefore, changing the values of h and k in the general formula for a cube root function will cause the graph to shift, but the overall shape of the graph will remain the same.

Based on the data, what is the probability that the next roll of this die is a 4?
Based on the data given, the probability of the next roll of the die being a 4 is 30%.
what is probability?
Probability is a measure of the likelihood of an event occurring. It is a number between 0 and 1, where 0 means the event is impossible and 1 means the event is certain to happen. The probability of an event can be calculated by dividing the number of favorable outcomes by the total number of possible outcomes.
To find the probability of rolling a 4 on the next roll, we need to divide the number of times 4 was rolled by the total number of rolls. In this case, 4 was rolled 9 times out of a total of 30 rolls.
So the probability of rolling a 4 on the next roll is:
9/30 = 3/10 = 0.3 = 30%
Therefore, based on the data given, the probability of the next roll of the die being a 4 is 30%.

To solve the equation:
x - 4 = 16 + 3x
Collect like terms:
x - 3x = 16 + 4
Then solve:
-2x = 20
x = -10
Answer: x is -10
Step-by-step explanation:
x - 4 = 16+3x
Transposing the x, and arranging in one side of equation
x - 3x = 16 + 4
now we changed the positions of x and we can simplify it.
so,
x - 3x = -2x -----------------(1)
16 + 4 = 20 ----------------(2)
Therefore the x - 3x = 16 + 4 will change into -2x = 20
Then x = 20 ÷ -2 = -10

an article marked at rs.8,000 is sold at rs6689.60 allowing some discount and adding vat.8f the rate of discount was double then the rate of vat, find the selling price of the article without vat
the rate of discount is double the rate of VAT. The selling price of the article without VAT is Rs. [tex]7,680.[/tex]
What is the selling price?Let's assume that the original selling price of the article is Rs. [tex]8,000.[/tex]
Let the rate of discount be x and the rate of VAT be y.
We know that the selling price of the article with discount and VAT is Rs. [tex]6,689.60.[/tex]
So, we can write the following equation:
Selling price = (Original price - Discount) + VAT
[tex]Rs. 6,689.60 = (Rs. 8,000 - Rs. 8,000 x (x/100)) + (Rs. 8,000 - Rs. 8,000 x (x/100)) x (y/100)[/tex]
Simplifying the equation, we get:
[tex]Rs. 6,689.60 = Rs. 8,000 (1 - x/100 + y/100 - xy/10000)[/tex]
Now, we are given that the rate of discount is double the rate of VAT. So, we can write:
[tex]x = 2y[/tex]
Substituting this value in the equation above, we get:
[tex]Rs. 6,689.60 = Rs. 8,000 (1 - 3y/100 + 2y^2/10000)[/tex]
Simplifying this equation further, we get a quadratic equation in y:
[tex]2y^2 - 3y + 0.41505 = 0[/tex]
Solving this quadratic equation using the quadratic formula, we get:
[tex]y = 10.5 or y = 0.01988[/tex]
Since the rate of VAT cannot be 10.5%, we will take y = 0.01988 (approx. 2%).
Now, we can calculate the rate of discount using x = 2y:
x = 4%
So, the selling price of the article without VAT can be calculated as follows:
Selling price without VAT = Original price - Discount
[tex]= Rs. 8,000 - Rs. 8,000 x\times (4/100)[/tex]
[tex]= Rs. 7,680[/tex]
Therefore, the selling price of the article without VAT is Rs. [tex]7,680.[/tex]
