What is the degree of the polynomial 2x² 5x³ 7 *?
The degree of a polynomial is the highest power of the variable in the equation. In this case, the equation 2x² 5x³ 7 has the highest power of x being 3, so the degree of the polynomial is 5.
Step 1: Identify the highest power of the variable (x).
Step 2: Count the number of terms in the equation.
Step 3: The degree of the polynomial is the highest power of the variable plus the number of terms minus one.
Step 4: In this case, the highest power of x is 3 and the number of terms is 3, so the degree of the polynomial is 3 + 3 - 1 = 5.
The degree of the polynomial 2x² 5x³ 7 is 5. This can be calculated by taking the highest power of the variable (x) and adding it to the number of terms in the equation (3), and then subtracting 1.

Is the triangle with sides 25 cm 5 cm and 24 cm a right angle triangle?
The triangle formed by sides 24, 25 and 5 cm is not a right angled triangle.
What is Pythagoras Theorem ?In a right-angled triangle, the square of the hypotenuse side is equal to the sum of the squares of the other two sides, according to Pythagoras's Theorem. These triangle's three sides are known as the Perpendicular, Base, and Hypotenuse. Due to its position opposite the 90° angle, the hypotenuse in this case is the longest side. When the positive integer sides of a right triangle (let's say sides a, b, and c) are squared, the result is an equation known as a Pythagorean triple.
A right triangle's three sides are related in Euclidean geometry by the Pythagorean theorem, also known as Pythagoras' theorem. According to this statement, the areas of the squares on the other two sides add up to the size of the square whose side is the hypotenuse.
Let us consider the triangle is a right angle triangle
so,
24 and 5 will be the base and heights
[tex]\sqrt{24\x^{2} + 5\x^{2} } = 24.51\\[/tex]
so 25 is not equal 24.51 cm
so the triangle formed by sides 24, 25 and 5 cm is not a right angled triangle.

A figure is scaled using the parallel method with center O and scale factor 13 . How do the lengths in the scale drawing compare to the corresponding lengths in the original figure?
The lengths in the scale drawing are the corresponding lengths in the original figure.
The lengths in the scale drawing are smaller than the corresponding lengths in the original figure.
What happens when a scale factor is less than 1 ?When the scale factor is less than 1, the image of a shape will be reduced in size compared to the original shape. This means that all dimensions of the shape will be scaled down by the same factor. For example, if a shape is scaled down by a factor of 0.5, its length, width, and height will all be half the size of the original shape. Additionally, the area and volume of the image shape will be scaled down by the square and cube of the scale factor respectively.
In other words, when the scale factor is between 0 and 1 it will be a reduction and if it's greater than 1 it will be an enlargement.
As can be seen from the question, the scale factor is less than one as it is 1 / 3. This means that the lengths on the scale drawing would be smaller than the lengths on the original drawing.

Find m∠ABC and m∠CBD if m∠ABD =120°
The measures of angles m∠ABC = 36° and m∠CBD = 84°.
What is geometryGeometry is a branch of mathematics that deals with shapes, sizes, angles, and dimensions of objects.
The angle m∠ABD = 120° is the result for the sum of the two angles m∠ABC and m∠CBD so;
m∠ABC + m∠CBD = m∠ABD
2x + 5x - 6 = 120°
7x - 6 = 120° {add 6 to both sides}
7x = 120° + 6°
7x = 126° {divide through by 7}
x = 126°/7
x = 18
2x = 2(18) = 36°

Colin will have a total amount of $ 675.90 with Colin.
Compound interest:
The interest charged on a loan or deposit is known as compound interest. It is the idea that we used the most frequently on a daily basis. Compound interest is calculated for an amount based on both the principal and cumulative interest.
The formula for compound interest is given by
A = P (1 + r/n)^ntHere we have
Colin invests $600 at a rate of 1.5% per year compound interest for 8 years
Here principal amount, p = $ 600
Rate of interest, r = 1.5% =
Number of compounds per year = 1
Time period, t = 8
By the Compound interest formula A = P (1 + r/n)^nt
A = 600( 1 + 0.015/1)⁽¹⁾⁽⁸⁾
A = 600(1.015)⁸

What is the relationship between heart rate and oxygen consumption during exercise?
During exercise, there was a substantial link between heart rate, coronary flow, and cardiac oxygen consumption. As heart rate increases, so does oxygen consumption, which seems to reach a maximum at very fast heart rates.
Your pulse and heart rate both serve as indicators of how your heart is working. Your heart rate is the number of times it beats in a minute. Your arteries widen as a result of the number of times your heart beats every minute.
In healthy people, heart rate, workload, and oxygen consumption are all linearly connected up to a certain point. The heart's reaction to physical exercise or stress is considered to be controlled by the sympathetic nervous system.

Mrs. Byers is making 5 costumes that each require 1 yards of blue
fabric and a certain amount of red fabric. She will use 8 yards in all.
Write and solve an equation to determine the number of yards of red
fabric r she will need for each costume.
We can start by using the following equation to determine the number of yards of red fabric r she will need for each costume:
1 + r = y (y represents the total number of yards of fabric for each costume)
We know that the total number of yards for all the costumes is 8 and there are 5 costumes, so we can use this information to set up another equation:
5y = 8 (y represents the total number of yards of fabric for each costume)
Now we can substitute the first equation into the second equation to get:
5(1 + r) = 8
Expanding the left side of the equation:
5 + 5r = 8
Subtracting 5 from both sides:
5r = 3
Dividing both sides by 5:
r = 3/5
So, Mrs. Byers will need 3/5 yards of red fabric for each costume.

Is it possible to form a triangle whose sides are 3.5 cm 4.5 cm 7.5 cm long?
Yes, it is possible to form a triangle with sides of 3.5cm, 4.5cm, and 7.5cm. This is because these triangle's sides adhere to the triangle inequality theorem.
The triangle inequality theorem which states that the sum of the lengths of any two sides of a triangle must be greater than the length of the third side. This is because in order to form a triangle, the sum of the lengths of any two sides must be greater than the length of the third side, otherwise it would be impossible to connect the three sides and form a closed shape.
In this case,
3.5 cm + 4.5 cm = 8 cm > 7.5 cm
3.5 cm + 7.5 cm = 11 cm > 4.5 cm
4.5 cm + 7.5 cm = 12 cm > 3.5 cm
So it is possible to form a triangle with these side lengths.

What are longitude for Class 5?
Longitudes: The vertical lines running north-south, join the two poles. They are called the meridians of longitude. They are spaced farthest apart at the equator and converge at a point at each pole.
Horizontal lines called latitudes are used to measure distances north or south of the equator. Vertical lines known as longitudes are used to determine the west or east of the meridian in Greenwich, England. Latitude and longitude work together to help cartographers, geographers, and others find specific locations on the globe.
What is the uses of latitude?
Any location's distance from the equator may be determined using its latitude, which is based on its degree. We can locate any point on Earth using longitude and latitude. The GPS or Global Positioning System uses these coordinates.
The grid system that enables us to locate absolute or precise places on the surface of the Earth is made up of latitude and longitude. Latitude and longitude can be used to pinpoint certain locations. Landmark identification also benefits from knowledge of latitude and longitude.

Which points lie on the graph of f(x) = log9x?-1/81, 20,11/9, -13, 2439,181,2
The points on the graph of f(x) = log9x are (20, 4.5), (11/9, 0.087183), (2439, 3.168910), (181, 2.55231), and (2, 1).
The points on the graph of f(x) = log9x can be calculated by substituting the given values of x in the equation. For example,
f(-1/81) = log9(-1/81) = log9(-1) - log9(81) = undefined
f(20) = log9(20) = log9(2*2*2*5) = log9(2) + log9(2) + log9(2) + log9(5) = 1 + 1 + 1 + 1.5 = 4.5
f(11/9) = log9(11/9) = log9(11) - log9(9) = 1.041393 - 0.954210 = 0.087183
f(-13) = log9(-13) = log9(-1) - log9(13) = undefined
f(2439) = log9(2439) = log9(3*13*37) = log9(3) + log9(13) + log9(37) = 0.477121 + 1.11394 + 1.579789 = 3.168910
f(181) = log9(181) = log9(3*3*7*7) = log9(3) + log9(3) + log9(7) + log9(7) = 0.477121 + 0.477121 + 0.84509 + 0.84509 = 2.55231
f(2) = log9(2) = log9(2) = 1
Hence, the points on the graph of f(x) = log9x are (20, 4.5), (11/9, 0.087183), (2439, 3.168910), (181, 2.55231), and (2, 1).
