Square ABCD has sides of length 3. Segments CM and CN divide the square's area into three equal parts. How long is segment CM?
A √10
B √12
C √13
D√ 14
E √ 15
The length of segment CM is equal to the square root of 10. This is determined by dividing the area of the square ABCD, which has sides of length 3, into three equal parts, resulting in a segment of length √10.
The area of square ABCD can be calculated by squaring the length of one side, which is 3, to get 9. To divide this area into three equal parts, each part must have an area of 3. To find the length of segment CM, the square root of this area, 3, must be taken, resulting in a length of √10.
To find the length of segment CM in square ABCD, the area of the square must first be determined. This can be done by squaring the length of one side, which is 3, resulting in an area of 9. To divide this area into three equal parts, each part must have an area of 3. This means the length of segment CM must be the square root of 3, which is equal to √10.

The expression that represents the length of the rectangle is x + 5
What is meant by Area of a rectangle?Dimensions of a rectangle. A = l × b. Once a rectangle's length and breadth are known, its area may be computed. The rectangle's area can be measured in square units by multiplying the length and width. The region that a rectangle occupies in a two-dimensional space is known as a rectangle's area. Another way to describe a rectangle's area is the quantity of square units needed to fill it entirely. The whole distance around the outside of a rectangle is referred to as the rectangle's perimeter.The area of a rectangle is described as follows:
area = lw
where
l = length
w = width
Therefore,
area = x² + 8x + 15
w = x + 3
Therefore,
x² + 8x + 15 = (x + 3)l
divide both sides by x + 3
l = x² + 8x + 15 / x + 3
l = (x+3)(x+5) / (x + 3)

−4≤−2(y−1)<2
Step 2 of 2 : Graph the solution set.
The solution set for the inequality -4≤-2(y-1)<2 is the set of all y-values that make the inequality true.
To graph the solution set, we can begin by plotting the inequality as an inequality on the y-axis, and then identifying the solutions that make the inequality true:
First, we can simplify the left side of the inequality: -4≤-2(y-1)
Next, we can solve for y by isolating y: -4/2≤y-1
Then we can add 1 to both sides of the inequality: -2≤y
Now, we can graph the inequality y ≥ -2, which is a line that is equal to or greater than -2.
On the right side, we have -2(y-1)<2
2(y-1)>-2
y-1>-1
y>-1
So we can graph the inequality y>-1, which is a line that is greater than -1.
So the solution set is the region above the line y=-2 and below the line y=-1. The region is a strip between two lines.
It is important to note that the solution set doesn't include the values of the lines, as the inequality is strict, not inclusive.

¿A qué altura está la cometa de Ana si su cuerda mide 8 metros y tendría que moverse 6 metros para situarse debajo de ella?
The kite is 10 meters high
Solving for the height:To calculate how high Ana's kite is, you can use the Pythagorean theorem. The theorem states that in a right triangle, the square of the length of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the other two sides.
In this case, the length of the string is one side of the triangle and the distance Ana needs to move to get under the kite is the other side. The height of the kite is the hypotenuse.
Therefore, the height of the kite can be calculated by:
height = [tex]\sqrt({string^{2} +distance^{2}) }[/tex]
height = [tex]\sqrt{(8^{2} + 6^{2} )[/tex]
height = √(64 + 36)

a. f"(2)
f"(x) = df'(x)/dx = d(sin(πx) + x² +3)/dx = cos(πx) + 2x
f"(2)=cos(π × 2) + 2 × 2
f"(2)=cos(2π) + 4
f"(2)=1 + 4
f"(2)=5
b. Equation for the line tangent to the graph of y = 1/f(x) at x = 0
We first find f(x) by integrating f'(x)
f(x) = ∫f'(x)dx = ∫(sin(πx) + x² +3)dx = -cos(πx)/π + x³/3 +3x + C
f(0) = 2 so,
2 = -cos(π × 0)/π + 0³/3 +3 × 0 + C
2 = -cos(0)/π + 0 + 0 + C
2 = -1/π + C
C = 2 + 1/π
f(x) = -cos(πx)/π + x³/3 +3x + 2 + 1/π
f(x) = [1-cos(πx)]/π + x³/3 +3x + 2
y = 1/f(x) = 1/([1-cos(πx)]/π + x³/3 +3x + 2)
The tangent to y is thus dy/dx
dy/dx = d1/([1-cos(πx)]/π + x³/3 +3x + 2)/dx
dy/dx = -([1-cos(πx)]/π + x³/3 +3x + 2)⁻²(sin(πx) + x² +3)
at x = 0,
dy/dx = -([1-cos(π × 0)]/π + 0³/3 +3 × 0 + 2)⁻²(sin(π × 0) + 0² +3)
dy/dx = -([1-cos(0)]/π + 0 + 0 + 2)⁻²(sin(0) + 0 +3)
dy/dx = -([1 - 1]/π + 0 + 0 + 2)⁻²(0 + 0 +3)
dy/dx = -(0/π + 2)⁻²(3)
dy/dx = -(0 + 2)⁻²(3)
dy/dx = -(2)⁻²(3)
dy/dx = -3/4
At x= 0,
y = 1/([1-cos(π × 0)]/π + 0³/3 +3 × 0 + 2)
y = 1/([1-cos(0)]/π + 0 + 0 + 2)
y = 1/([1 - 1]/π + 2)
y = 1/(0/π + 2)
y = 1/(0 + 2)
y = 1/2
So, the equation of the tangent at (0, 1/2) is

g'(2) = [3(2)sinπ√(3(2)² + 4) + 18(2)(3(2)² + 4) + 9(2)]/√(3(2)² + 4)
g'(2) = [6sinπ√(12 + 4) + 36(12 + 4) + 18]/√12 + 4)
g'(2) = [6sinπ√(16) + 36(16) + 18]/√16)
g'(2) = [6sin4π + 576 + 18]/4)

Congruency is said to be defined on two triangles when they have exact same length of sides and equal angles between them. The shape and size are supposed to be the same even after rotation or flipping of triangles for them to remain congruent.
There are 4 criteria to test the congruency of the triangle and they are as follows:
SAS - This proves congruency when two sides and the angle between them are the same w.r.t both trianglesSSS - Two triangles are congruent if all three sides of both of them are equal w.r.t to each otherAAS- When Two pairs of corresponding angles and one pair of corresponding sides (not between the angles) are equal then this is trueASA- When Two pairs of corresponding angles and one pair of corresponding sides between the angles are equal then this is trueIn this set of triangles, (ABC, def) AB=DE, AC=DF, and ∠ABC= ∠DEF i.e., two sides and one angle are equal but it is not congruent because according to SAS criteria, the angle should be between AB and AC (or DE and DF)

Consider the following two algorithms which both are meant to print all multiples of 11 from 1 up to a user input positive integer value - upper. Which statement correctly compares the efficiency of these two algorithms?
Algorithm 1:
for (int i = 1; i <= upper; i++)

}
Algorithm 2:
for (int i = 1; i <= upper / 11; i++)
{
System.out.println(i * 11 + " ");
}
Algorithm 2 is more efficient than Algorithm 1 because it only needs to loop through the numbers up to upper/11 instead of upper. This means that it will take fewer iterations to reach the result, making it more efficient than Algorithm 1.
Algorithm 1 will make upper/11 more checks than Algorithm 2, resulting in a slower runtime. Additionally, Algorithm 2 avoids the need to check the modulus of each number, further reducing the computation time. Algorithm 2 only needs to loop through the multiples of 11, which are always 11 apart from each other, so it can skip over the other numbers between them.
This makes Algorithm 2 much faster than Algorithm 1 because it is only looping through a fraction of the numbers.

table of values for another, determine which has a
smaller minimum.
The Minimum for quadratic function f(x) is smaller than g(x)
and it is -5.
What is a quadratic function?
Quadratic function is also a second-degree polynomial function. The graph of a quadratic function is a parabola. The parabola opens upwards if a graph is made for the quadratic formula.
The point at which the function attains maximum or minimum value is the vertex of the quadratic function. When we say second degree, then the variable is raised to the second power like x^2.
A quadratic function is of the form f(x) = ax^2 + bx + c, where a, b, and c are the numbers with a not equal to zero.
Now,
As the we find minimum value by calculating the value for f(x) or g(x)
and from given values f(x) have minimum value of -5 and g(x) have minimum value of 3.
hence,
Minimum for quadratic function f(x) is smaller than g(x)

As the price of tickets rises from $200 to $250, the price elasticity of demand for business travelers is , and the price elasticity of demand for vacationers is , using the midpoint method. Therefore, the demand for airline tickets in this price range is elastic for vacationers because business travelers are sensitive to changes in price.
Answer:
The price elasticity of demand measures how responsive the quantity demanded is to a change in price. It can be calculated using the midpoint method, which is (change in quantity demanded / average quantity demanded) / (change in price / average price).
Using the midpoint method to calculate the price elasticity of demand for business travelers and vacationers, you would need more information such as the change in quantity demanded and the average quantity demanded for each group at different prices.
It is not possible to say if the demand is elastic or not for either group based on the information provided.

Find X
I’m not really sure how to do this
Answer:
x = 121°
Step-by-step explanation:
the shape is a heptagon (7 sides). the interior angles in a heptagon will always add up to 900°, so all you need to do is add all the known angles and subtract from 900.
140 + 133 + 145 + 117 + 119 + 125 = 779
900 - 779 = 121
this means that x = 121°

Which describes 4x and −7x
in this expression?
4x−5−7x
A. constant term
B. like terms
C. multiplication
D. simplify
======================================
Reason:
The 4x and -7x are like terms because they involve the same variable x. This allows us to combine the like terms to end up with -3x
4x-7x = -3x
-------
Another example of like terms is 2x and 5x.
Adding them gets us 2x+5x = 7x
We can think of it like saying "2 boxes + 5 boxes = 7 boxes". Replace each word "boxes" with the single letter "x" and we arrive at 2x+5x = 7x.
