Step-by-step explanation:

We have various of ways in which we can simplify an equation

for example

simplify: 2x – 4 = 10

soln

2x – 4 = 10

since we are looking for x we need to collect like terms

2x = 10 + 4

2x = 14

Then we will divide both sides by 2 to get x

x = 14/2

x = 7

N.B:- after solving an equation if you want to check the answer just substitute for the value

2x – 4 = 10

2(7) – 4 = 10

14 – 4 = 10

10 = 10

Answer:

the length of a room is 2 m longer than its breadth .if the area of its floor is 63 sq.m.calculate the length and the breadth of the room

Length and breadth

Let the length and breadth be l + 2 and l

Now,

\( \large \sf \: Area = l + 2 \times l \)

\( \large \sf \: 63 = l + 2 \times \: l\)

\( \large \sf \: 63 = 2l + {l}^{2} \)

\( \large \sf \: {l}^{2} + 2l - 63 = 0\)

\( \large \sf \: {l}^{2} (9l - 7l) - 63 = 0\)

Step-by-step explanation:

\(\frac{-5^2}{(-5)^2}\)

=> \(\frac{-25}{25}\)

=> -1

Answer:

-1

Step-by-step explanation:

-5^2 is -25 because you have to do exponents first, so 5^2 is 25. Add a negative symbol there, it becomes -25.

For the denominator, we do the exact same process, except a little different. Since there are parentheses around the negative five, we have to apply the negative symbol on the 5 before we do the exponents. After, we do -5^2 which is 25 because when you are multiplying negative, you always get a positive.

When we are all done with that, we put the numerator over the denominator to get -25/25, which is equivalent to -1.

Answer:

\(85\:\mathrm{units^2}\)

Step-by-step explanation:

All side lengths of a square are equal. The three squares create a right triangle, and the hypotenuse of this triangle represents the side length of the square.

All right triangles must follow the Pythagorean Theorem \(a^2+b^2=c^2\) where \(c\) is the hypotenuse of the triangle.

Therefore, let \(h\) be the side length of this largest square. Since the area of a square with side length \(s\) is given by \(s^2\), \(h^2\) will represent the area of the square:

\(\sqrt{35}^2+\sqrt{50}^2=h^2=\boxed{85\:\mathrm{units^2}}\)

Answer:

85

Step-by-step explanation:

We can use the Pythagorean theorem (a^2+b^2=c^2) to find the area of square adjacent to the third side.

Area of a square=side^2

So, we can substitute the areas of the squares that share side lengths with the triangle for a^2, b^2, and c^2 in the Pythagorean theorem.

For example, in the diagram above, the area of the square that shares a side with side length a is 35 square units. So, a^2=35.

Let's fill in the remaining values:

a^2 + b^2 = x^2

35+50-x^2
85=x^2
The area of the square adjacent to the third side of the triangle is 85 units^2.

It is not an entity that can take on different values, the consistency in measurement, the strength of the relationship between variables, or the truth of a measurement.

Validity is concerned with the degree to which a measure or conclusion accurately represents the concept or phenomenon it is intended to assess or describe. It focuses on the appropriateness and accuracy of inferences or interpretations based on the measurement or observation. Validity addresses the question of whether a measure or conclusion captures the intended construct or relationship and provides meaningful and reliable information.

Validity is distinct from other concepts mentioned. While an entity can take on different values, it is not synonymous with validity. Consistency in measurement refers to reliability, which is a separate concept related to the consistency and stability of measurements. The strength of the relationship between two variables is typically referred to as the correlation or association, but it is not directly related to validity. Lastly, the truth of a measurement is a broader philosophical concept, but validity specifically relates to the accuracy and appropriateness of a measure within a specific context or purpose.

To find the equation of a line when you have two points, you can use the point-slope formula. Here's how to do it:

1. Find the slope of the line using the two points:

slope = (y2 - y1) / (x2 - x1)

where (x1, y1) = (0, 3) and (x2, y2) = (5, 3)

slope = (3 - 3) / (5 - 0) = 0/5 = 0

2. Use the point-slope formula to find the equation of the line:

y - y1 = m(x - x1)

where m is the slope, and (x1, y1) is one of the points on the line. Using (0, 3) as the point, we get:

y - 3 = 0(x - 0) or y = 3

So the equation of the line is y = 3, a horizontal line passing through y = 3.

The domain of this equation is all real numbers, since x can take on any value and y will always be 3.

The range of this equation is a single value, y = 3, since the line is horizontal and every point on the line has the same y value of 3.

A) The new box with dimensions 10cm by 10cm by 3cm holds more cereal.

B) The new box with dimensions 10cm by 10cm by 3cm requires more material to make.

To determine which box holds more cereal, we need to calculate the volume of each box.

The volume of a rectangular box is given by the formula:

Volume = Length × Width × Height

Let's calculate the volumes for both boxes:

Original Box:

Length = 8 cm

Width = 3 cm

Height = 11 cm

Volume = 8 cm × 3 cm × 11 cm = 264 cm³

New Box:

Length = 10 cm

Width = 10 cm

Height = 3 cm

Volume = 10 cm × 10 cm × 3 cm = 300 cm³

A) The new box with dimensions 10cm by 10cm by 3cm holds more cereal because it has a larger volume of 300 cm³ compared to the original box with a volume of 264 cm³.

To determine which box requires more material to make, we need to calculate the surface area of each box.

The surface area of a rectangular box is given by the formula:

Surface Area = 2 × (Length × Width + Length × Height + Width × Height)

Let's calculate the surface areas for both boxes:

Original Box:

Length = 8 cm

Width = 3 cm

Height = 11 cm

Surface Area = 2 × (8 cm × 3 cm + 8 cm × 11 cm + 3 cm × 11 cm) = 374 cm²

New Box:

Length = 10 cm

Width = 10 cm

Height = 3 cm

Surface Area = 2 × (10 cm × 10 cm + 10 cm × 3 cm + 10 cm × 3 cm) = 380 cm²

B) The new box with dimensions 10cm by 10cm by 3cm requires more material to make because it has a larger surface area of 380 cm² compared to the original box with a surface area of 374 cm².

To determine whether the series ∞ 9 + 4n, where n starts from 1, converges or not, we can analyze the behavior of its terms as n increases.

The series can be rewritten as:

9 + 4(1) + 4(2) + 4(3) + ...

Simplifying, we have:

9 + 4 + 8 + 12 + ...

We can observe that each term is increasing by 4. As n approaches infinity, the terms in the series become larger and larger without bound. Therefore, the series diverges, meaning it does not converge to a specific value.

Hence, the series diverges, and there is no value associated with its convergence.

There is no solution for the given function \(\rm f(x) = -0.5|2x+2|+1\) when f(x) = 6 option fourth is correct.

It is given that the function  \(\rm f(x) = -0.5|2x+2|+1\)

It is required to find the values of x when f(x) = 6

It is defined as a special type of relationship and they have a predefined domain and range according to the function.

We have a function:

\(\rm f(x) = -0.5|2x+2|+1\)

And f(x) = 6

Putting the value of f(x) in the above equation, we get:

\(\rm 6 = -0.5|2x+2|+1\)   or

\(\rm -0.5|2x+2|+1= 6\\\\\rm -0.5|2x+2|= 6-1\\\\\rm -0.5|2x+2|+5\\\\\rm |2x+2|= \frac{5}{-0.5} \\\\\rm |2x+2|= -10\)

Here we can see the mod function values is negative which is not possible, hence there is no solution for the above equation for any 'x'

Thus, there is no solution for the given function \(\rm f(x) = -0.5|2x+2|+1\) when f(x) = 6.

The integral of 1x does not exist as it is a function without a definite integral. This is because the function has no area associated with it. The area under the function is zero and therefore it is not integrable.

In calculus, the integral of a function f(x) is defined as the area under its curve, and is often represented using the symbol ∫f(x)dx. For a function to have an integral, it must satisfy certain conditions, including being continuous over a certain interval and having a finite area under its curve.

However, the function 1/x is not continuous over all intervals, and in particular, it has a vertical asymptote at x=0. This means that as x approaches 0 from either side, the value of 1/x becomes arbitrarily large, resulting in an infinitely large area under the curve for any interval containing x=0.

Error rate refers to the frequency or proportion of errors made in a particular context or process. It is commonly used in various fields such as statistics, computer science, and quality control.

To find the error rate for the training subset, we can use the fact that the average error rate is 0.06.

Let's denote the error rate for the training subset as E_train. We can express the average error rate as:

average error rate = (error rate for training subset + error rate for test subset) / 2

0.06 = (E_train + error rate for test subset) / 2

Multiplying both sides of the equation by 2, we get:

0.12 = E_train + error rate for test subset

Since K=1, the error rate for the test subset would be 0.12 - E_train.

Therefore, we can expect the error rate for the training subset to be 0.12 - E_train.
