find the value of x ​

Answer:

1330.5 cm³

Step-by-step explanation:

To find the volume you want to find the area of the circle and then times this  by 14 which is the length of the shape

Area of circle = πr²

11 = the diameter so 5.5 = radius

5.5² x π = 121/4 π

times this by 14 to get  1330.464489 cm³

to 1dp = 1330.5 cm³

Answer:

1330cm³ (rounded to 3 s.f.)

Step-by-step explanation:

The formula of finding the volume of a cylinder is: \(\pi\) × r² × h

r is the radius of the cylinder, which is also half of the diameter.

You know the diameter is 11cm and the height (h) is 14cm.

Volume of cylinder = \(\pi\) × (11÷2)² × 14

                                = \(\pi\) × 5.5² × 14

                                = \(\pi\) × 30.25 × 14

                                = 423.5\(\pi\)

                                = 1330cm³ (rounded to 3 s.f.)

Given:

The function \(g(x)\) doubles the square of the input and then subtracts 13.

To find:

The value of \(g(3)\).

Solution:

Let \(x\) be the input value.

The square of the input is \(x^2\).

Doubles the square of the input \(2x^2\).

Doubles the square of the input and then subtracts 13, i.e., \(2x^2-13\).

So, the function is:

\(g(x)=2x^2-13\)

Putting \(x=3\) in the above function, we get

\(g(3)=2(3)^2-13\)

\(g(3)=2(9)-13\)

\(g(3)=18-13\)

\(g(3)=5\)

Therefore, the value of \(g(3)\) is 5.

Answer:

The relation represented by diagram 4 is NOT a function.

Step-by-step explanation:

To tell if a relation is not a function, pay attention to the x-intercepts. If there is more than one y-intercept with the same x-intercept, then it is not a function, because a function can only have one output (y-value) for each input (x-value).

According to the fourth diagram, the domains include 1, 2, and 3 while the range includes A, B, and C. Also, the ordered pairs would go as follows according to the arrows:

(1, A), (2, A), (2, B), (3, C)

While the y-values, A and B, are different, they share the same input, 2. Therefore, the relation represented by the 4th diagram is NOT a function.

Hope this helps!

According to the equation model V=P(1-r)^t, the approximate value of Doug's car after 4¹/₂ years is $9,200.

The equation is a mathematical statement or model that shows that two mathematical expressions are equal.

In this situation, the mathematical expressions equal to each other are V, the car's depreciated value, and P(1-r)^t, which combines variables.

Cost of the new car = $25,000

Depreciation rate per annum = 20%

Value of the car = V

The price paid initially = P = $25,000

The annual rate of depreciation = r

Depreciation period = 4¹/₂ years

Equation model: V=P(1-r)^t

Depreciated value after 4 1/2 years, V = $25,000 (1 - 0.2)^4¹/₂

= $9,158.93

= $9,200

Thus, using the equation model, after 4¹/₂ years, the value of Doug's car has depreciated to $9,200.

The probability that a randomly selected student in the course has received an A or B is 0.65 or 65%

To find the probability that a randomly selected student in the course has received an A or B, we can use conditional probability based on the given information.

Let's denote the event of doing homework regularly as A, and the event of getting a grade of A or B as B.

We know that P(A) = 0.8, which represents the probability of a student doing homework regularly.

We also know that P(B|A) = 0.75, which represents the probability of getting a grade of A or B given that the student does homework regularly.

Similarly, P(B|A') = 0.25, which represents the probability of getting a grade of A or B given that the student does not do homework regularly.

We can now calculate the probability of getting an A or B using the law of total probability:

P(B) = P(A) * P(B|A) + P(A') * P(B|A')

= 0.8 * 0.75 + 0.2 * 0.25

= 0.6 + 0.05

= 0.65

The probability that a randomly selected student in the course has received an A or B is 0.65 or 65%.

A quadrilateral with congruent diagonals is a rectangle. In a rectangle, the opposite sides are parallel and equal in length, and all interior angles are 90 degrees. The diagonals in a rectangle are congruent, which means they have the same length.

This property distinguishes rectangles from other quadrilaterals such as squares, rhombuses, parallelograms, kites, isosceles trapezoids, and trapezoids. Although squares and rhombuses also have congruent diagonals, they possess additional properties that rectangles do not have, such as all sides being equal in length for both squares and rhombuses, and all angles being 90 degrees for squares.

On the other hand, parallelograms, kites, isosceles trapezoids, and trapezoids do not have congruent diagonals. Therefore, a quadrilateral with congruent diagonals is a rectangle.

Relationship-oriented groups put a lot of effort into encouraging, developing, and supporting their teams' members and their internal connections. By building positive connections and effective communication, this leadership style promotes effective cooperation and collaboration. Relationship-oriented leaders put the needs of the group as a whole first and spend time and energy attending to each person's needs. This may entail providing rewards like bonuses, offering mediation services to resolve conflicts in the workplace or in the classroom, engaging in more relaxed interactions with team members to learn about their strengths and weaknesses, fostering a non-competitive and open work environment, or simply exercising personable or supportive leadership.

Team members gain from relationship-oriented leadership because they work in an environment where the leader is concerned about their welfare. Relationship-focused executives are aware that creating a productive atmosphere necessitates making people feel motivated. These kinds of leaders prioritize people in order to guarantee that issues like personal disputes, work discontent, resentment, and even boredom don't significantly lower productivity. Additionally, because they are certain that the team leader would offer assistance if necessary, team members may be more inclined to take risks.

The percent change is computed by comparing the net worth of this year to the net worth of the previous year and expressing it as a percentage.

Total assets = $650 (computer) + $18,500 (car) + $2,700 (savings account) + $10,000 (retirement savings) + $5,000 (furniture) = $37,850

Total liabilities = $24,000 (student loan balance) + $500 (credit card debt) + $9,000 (car loan balance) = $33,500

Net worth = Total assets - Total liabilities = $37,850 - $33,500 = $4,350

To calculate the percent change from last year to this year, we use the formula: Percent change = [(New value - Old value) / Old value] * 100

Percent change = [(Net worth this year - Net worth last year) / Net worth last year] * 100 = [($4,350 - $2,000) / $2,000] * 100 = 117.5%

Find the lengths of the three sides of the triangle using the distance formula.

Once you have the lengths of the sides, check if any of the three sides satisfy the Pythagorean theorem, which states that in a right triangle, the square of the length of the hypotenuse (the longest side) is equal to the sum of the squares of the other two sides. In other words, if a² + b² = c², where c is the longest side, then the triangle is a right triangle.

If one of the sides satisfies the Pythagorean theorem, then the triangle is a right triangle.
