The only value of c that satisfies the conclusion of the Mean Value Theorem on the closed interval [0,3] is c = 2.

The Mean Value Theorem states that if a function f is continuous on a closed interval [a, b], then there exists some c in the interval such that

f'(c) = (f(b) - f(a)) / (b - a).

In the case of f(x) = x(x-3) , on the closed interval [0,3], we can solve for c using the equation above.

We begin by calculating f'(c), which is equal to 2c - 3. Then, we set the equation equal to (f(3) - f(0)) / (3 - 0), which is equal to -3 / 3.

Substituting this into our equation for f'(c), we get 2c - 3 = -1, which simplifies to c = 2.

Therefore, the only value of c that satisfies the conclusion of the Mean Value Theorem on the closed interval [0,3] is c = 2.

Answer:

(x – 3)2 = 49 can be written as (x – 3) = ± √49.

To solve for x, we can square root both sides:

x -3 = ±7

Now we can add 3 to both sides:

x = 3 ±7

So the values of x are:

x = 3 + 7 = 10

x = 3 - 7 = -4

Hence the values of x are -4 and 10.

Step-by-step explanation:

Answer: Did you mean (x - 3)² = 49? If so, the answers are -4 and 10

Step-by-step explanation: This equation is a simple quadratic. We can square root both sides to get:

x - 3 = -7

OR

x - 3 = 7

(Remember 49 has a positive square root and a negative square root)

Now simple rearranging will yield our two answers: 10 and -4.

The area of the composite figure which consist 3 semicircles and a square with 4 centimeters is (6π+16) cm².

The area of the semicircle is the space occupied by it. It can be given as,

[tex]A_{s} = \frac{d^{2} }{8} \pi[/tex]

Here, (d) is the diameter of the semicircle.

Each side of the square measures 4 centimeters. The area of the square is square of its side. Thus,

Area of the square, [tex]A_{s}[/tex] = 4² = 16cm²

3 semicircles are connected to 3 sides of a square. Thus, the diameter of the semicircle is equal to 4 cm. The area of 3 semicircles is,

[tex]A_{sc} = 3 *\frac{4^{2} }{8} \pi\\A_{sc} = 6\pi[/tex]

The area of the composite figure is,

[tex]A = A_{s} + A_{sc} \\A = (6\pi + 16) cm^{2}[/tex]

Thus, the area of the composite figure which consist 3 semicircles and a square with 4 centimeters is (6π+16) cm².

Answer:

We know that the distance between Paris and Nice is about 920,000 meters. To convert this distance to kilometers we divide by 1000: 920,000/1000= 920 kilometers

We also know that the train travels at a speed of 230 kilometers per hour. To find out how long it will take Lola to travel from Paris to Nice, we divide the distance by the speed:

920/230 = 4 hours

So it will take Lola 4 hours to travel from Paris to Nice by train.

Answer: 4 hours actually kinda ez not gonna lie

Step-by-step explanation: 230 kilometers = 230000 meters. 230 * 1000 = 230000. Distance / speed = time. 920000/230000 = T(as in time). T = 4

Answer:

formula:

c^2 = a^2 + b^2 - 2abcos(C)

where c is the length of the diagonal, a and b are the lengths of the legs of the triangle (the non-parallel sides of the trapezoid), and C is the angle between them.

In this case, a = b = 7 feet and C = (180 - 140)/2 = 20 degrees. We can plug these values into the formula to find:

c^2 = 7^2 + 7^2 - 2(7)(7)cos(20)

c = sqrt(98 + 49cos(20))

To use the Law of Sines to find the length of the shorter base, we can use the following formula:

a/sin(A) = b/sin(B) = c/sin(C)

where a, b, and c are the sides of the triangle and A, B, and C are the angles opposite those sides.

Since we know a and b, we can use the formula to find:

x/sin(140) = 7/sin(20)

x = 7sin(140) / sin(20)

Note that the value of c will be in squared units, so you need to take the square root to get the actual length of the diagonal.

The solution for the compound inequality is -2>x≥-4. Therefore, option C is the correct answer.

Inequalities are the mathematical expressions in which both sides are not equal. In inequality, unlike in equations, we compare two values. The equal sign in between is replaced by less than (or less than or equal to), greater than (or greater than or equal to), or not equal to sign.

The given inequality is 3<-2x-1≤7.

Here, 3<-2x-1

Add 1 on both the sides of an inequality, we get

4<-2x

Divide -2 on both the sides of an inequality, we get

-2>x

Here, -2x-1≤7

Add 1 on both the sides of an inequality, we get

-2x≤8

Divide -2 on both the sides of an inequality, we get

x≥-4

The solution is -2>x≥-4

On solving the provide question, we can say that by plotting data they can own 8 to 10 video games.

The most typical approach to display data using a chart is a graph that shows the relationship between two additional variables. Diagrams created by hand or on a computer are also acceptable. Move 2 units to the right after starting at the origin before going 3 units up. The coordinates for the points 2, 3, should be shown on the coordinate plane. Clearly state your points. The pink dot with the letter P thus stands for 2.3. Before creating a line chart, you need first generate a number line for each value in your data collection. Put an X (or dot) over each value of the data on the number line after that. For each instance when a value appears in a record, place an X over the corresponding number.

A visual representation of data where numbers on the left side of a chart show one part of each value and numbers on the right side of the chart show the other is called a bar chart. A bar chart is a chart that uses rectangular bars to represent different values or categories. Each bar has a length that represents a value or a category. The left side of the chart is called the y-axis, or the vertical axis, and the right side of the chart is called the x-axis, or the horizontal axis. The x-axis typically shows the categories, and the y-axis shows the values of those categories. The height of each bar represents the value of the data point, with the height on the y-axis and the categories on the x-axis. This type of graph is useful for comparing the relative sizes of different groups or categories, as well as spotting trends and patterns.

Given system of inequalities:

Plot the inequality and the given points to determine which of them fall into solution area.

See attached.

As we see only two points fall in the solution area, brown zone on the bottom: (6, −2), (6, 0.5).

(Answer:

(6, 5)

Step-by-step explanation:

For this question, there are not two correct choices.

Given systems:

y ≤ 2/3x + 1

y > -1/4x + 2

For the first equation, the y-intercept is 1, and the rate of change is 2/3 (rise over run). The inequality symbol is less than or equal to (≤), meaning this will be a solid line and the area shaded will be below the line.

For the second equation, the y-intercept is 2, and the rate of change is -1/4 (this means it is decreasing in number, therefore the line is going down). The inequality symbol is greater than (>), meaning this will be a dashed line and the area shaded will be above the line.

the area overlapped is where the solution will be. The answer is (6, 5) because it lies on the solid line of the first inequality, indicating it does satisfy the first inequality. Any point on the solid line satisfies the inequality. The point also lies above the second inequality, meaning it is a solution to the system.

Also, if you plug it into the system of inequalities, all the outcomes will make sense.

The percentage by mass of water contained in the original sample is 24.8%.

Percentage:

In mathematics, a percentage (from Latin: per centum, "by a hundred") is a number or ratio expressed as a fraction of 100. It is often denoted using the percent sign, "%",[1] although the abbreviations "pct.", "pct" and sometimes "pc" is also used.[2] A percentage is a dimensionless number (pure number); it has no unit of measurement.

To find the percent by mass of water in the original sample, we need to find the mass of the water that was lost upon heating. We can do this by subtracting the constant mass (6.20 g) from the initial mass (8.24 g).

mass of water = 8.24 g - 6.20 g = 2.04 g

To find the percentage, we divide the mass of water by the initial mass and multiply by 100:

percent by mass of water = (2.04 g / 8.24 g) x 100 = 24.8%

So the percentage by mass of water contained in the original sample is 24.8%.

The first inequality, x ≥ 14, is a vertical line with x-intercept at (14, 0).

The second inequality, x + y ≥ 15, is a line with a slope of 1, passing through the point (0, 15) and with y-intercept at (0, 15).

The third inequality, 0.5x + 0.1y ≤ 1, is a line with a slope of -5, passing through the point (2, 0.2) and with y-intercept at (0, 0.2).

The values of variables in the kite is - x = 35°, y = 12.5°. The angles measures of the kite are ∠a = 110°, ∠b = 12.5°, ∠c = 5° and ∠d = 110°.

What is a kite?

A kite is a quadrilateral having reflection symmetry across a diagonal in Euclidean geometry. A kite has two equal angles and two pairs of adjacent equal-length sides as a result of its symmetry. Another name for kites is deltoids.

The given angles of the kite are -

∠a = (3x+5)°

∠b = y°

∠c = (2y-20)°

∠d = (4x-30)°

According to the properties of kite -

The two angles are equal where the unequal sides meet.

So, ∠a = ∠d

(3x+5)° = (4x-30)°

3x - 4x = -30 - 5

-x = -35

x = 35°

Substituting to find the value of ∠a -

∠a = (3x+5)°

∠a = [3(35)+5]°

∠a = (105+5)°

∠a = 110°

Substituting to find the value of ∠d -

∠d = (4x-30)°

∠d = [4(35)-30]°

∠d = (140-30)°

∠d = 110°

According to the properties of the kite ∠ADC = 90°.

So, ∠c = 90°/2 as line BD is a bisector.

(2y-20)° = 90°/2

2(2y-20)° = 90°

(4y - 40)° = 90°

4y = 90° - 40°

4y = 50°

y = 12.5°

Substituting to find the value of ∠b -

∠b = y°

∠b = 12.5°

Substituting to find the value of ∠c -

∠c = (2y-20)°

∠c = [2(12.5)-20]°

∠c = (25-20)°

∠c = 5°

Therefore, the value of angles are ∠a = 110°, ∠b = 12.5°, ∠c = 5° and ∠d = 110°.
