Answer: 9 numbers

Step-by-step explanation:

Number C₃ = 5 is written in the center.

Matrices are the arrangement of numbers, variables, symbols, or expressions in the rectangular format, in the form of rows and columns.

Square matrix is a matrix with the same number of rows and columns.

Given,

Sum of neighbors of 6 and 8  is 10.

By the figure,

If C₁ = 6

then, 1 + C₃ + 2 = 10 ⇒ C₃ = 7

But if C₃ = 7, then sum for neighbors of any unknown column cannot be 10.

Now, C₂ = 5

then, 1 + C₃ + 4 = 10 ⇒ C₃ = 5

Considering

C₃ + 2 + 3 = 10 that are neighbors to C₄

5 + 2 + 3 = 10

Thus, C₄ = 8

Hence, C₃ = 5 is the number written in center.

The average value of a function over the interval to be -π/4 + C/3π.

In this case, we need to calculate the average value of y=xsin(x) over the interval [0,3π/2]. To calculate this, we must first calculate the integral of the function over the interval. This is done by finding the antiderivative of the function and then evaluating the antiderivative at the upper and lower limits of the interval. The antiderivative of the function is -cos(x) + sin(x)x + C. Evaluating this at the lower and upper limits of the interval, we get 0-0 + 0 + C = C. To calculate the average value of the function, we divide the integral by the length of the interval. The length of the interval is 3π/2, so the average value of the function over the interval is the integral divided by 3π/2. Evaluating the integral, we get -cos(3π/2) + sin(3π/2)(3π/2) + C. Substituting in the values, we get -(-1) + 1(3π/2) + C = -π/2 + C. Finally, dividing this by 3π/2, we get the average value of the function over the interval to be -π/4 + C/3π.

Answer:

150.72

Step-by-step explanation:

area of a cylinder = top circle + bottom circle + lateral

lateral = perimeter of the circle * height = 2π*2 * 10 =40π

area of a circle = πr² = 4π

top & bottom =8π

total = 40π+8π =48π = 150.72

The surface area of a solid cylinder of radius 2.0 cm and height 10.0 cm is [tex]$$150.8 \mathrm{~cm}^2$$[/tex].

The sum of the areas of all the faces or surfaces that surround a solid results in its total surface area. The tops and bottoms (bases) as well as the remaining surfaces make up the faces. The surface area of a solid without its bases is known as its lateral surface area.

The area of the cylinder is determined by adding the areas of the curving surface and its two circular bases.

A cylinder's volume is π r² h, and its surface area is 2π r h + 2π r².

Total surface area [tex]$S=2 \pi r h+2 \pi r^2$[/tex]

Substitute the values in the above equation, we get

[tex]$$\Rightarrow \mathrm{S}=2 \pi \mathrm{r}(\mathrm{r}+\mathrm{h})=2 \times 3.1416 \times 2 \times 12$$[/tex]

simplifying the equation, we get

[tex]$$\Rightarrow \mathrm{S}=150.8 \mathrm{~cm}^2$$[/tex]

[tex]$\Rightarrow \mathrm{S} \approx 1.51 \times 10^4 \mathrm{~mm}^2$$[/tex]

Your roommate shook 10 hands at the party you and your roommate hosted.

If each person at the party shakes hands with a different number of people, and each person did not shake hands with their own roommate, then the number of hands each person shakes will form a set of integers from 0 to 19, with no duplicates. Since there are 20 people at the party, the sum of the numbers from 0 to 19 is 20 * 19 / 2 = 190.

If we subtract the number of hands that each person shakes from this sum, we find that the number of hands that my roommate shook is equal to 190 - (0 + 1 + 2 + ... + 19) = 190 - (0 + 19) * 20 / 2 = 190 - 20 * (19 / 2) = 190 - 20 * 9.5 = 190 - 190 = 0. This is not possible, since each person must shake at least one hand. The only possible answer is 10, which satisfies the conditions.

In this question we find the case of geometric sequence, that is, a set of values generated by a exponential function, whose definition is shown below:

y = a · rⁿ⁻¹, n ≥ 1

Where:

If we know that y₄ = - 25 and y₉ = 25 / 32, then the expression that generates the geometric sequence is:

- 25 = a · r³

25 / 32 = a · r⁸

- 1 / 32 = r⁵

r = - 1 / 2

a = - 25 / r³

a = - 25 / (- 1 / 2)³

a = - 25 / (- 1 / 8)

a = 200

y = 200 · (- 1 / 2)ⁿ⁻¹

The cost of eight ruler and three pens is le79.125.

Let's call the cost of a pen x and the cost of a ruler y. From the first statement, we can create the equation:

x + 3y = 29

And from the second statement:

6x + 2y = 48

That is dividing by 2, 3x + y = 24

Now we have two equations with two variables and can use substitution or elimination method to find the values of x and y.

Let's use substitution:

x = 29 - 3y

Substituting this into the second equation:

3(29 - 3y) + y = 24

87 - 9y + y = 24

8y = 63

y = 63/ 8

y = 7.875

Now that we have the value of y, we can use the first equation to find the value of x:

x = 29 - 3y = 29 - 3 * 63/8

= 5.375

So, a pen costs le5.375 and a ruler costs le7.875. To find the cost of 8 rulers and 3 pens, we multiply:

8 * 7.875 + 3 * 5.375 = le79.125

The cost of 8 rulers and 3 pens is le79.125.

We can't solve this problem if there is no context given. Since nothing is mentioned, it is safe to assume that PR and QR are line segments. Based on the nomenclature, it may be a collinear system of 3 points: P, Q and R. The equation should be:

PR = PQ + QR

Assume x is referred to line PQ

13 x = 15x - 8

solving by calculating the value of x to satisfy the equation: Subtracting 13x from both sides

13x - 13x = 15x - 8 - 13x

0 = 15x - 13x - 8

2x - 8 = 0

Adding 8 to both sides:
