Answer:

A=30cm^2

Step-by-step explanation:

Area of a parallelogram is base X height

in this diagram base = 10 cm

height = 3 cm

3 X 10 = 30

Answer:

30 cm^2

Step-by-step explanation:

Formula of parallelogram = base * height

height = 3

base = 10

10(3) = 30

Answer:

buses can hold 30 and vans can hold 17.

Step-by-step explanation:

Let the amount a van can hold be v and the amount a bus can hold be b.

12 vans and 12 buses totals 564: 12v + 12b = 564 (equation 1)

6 vans and 13 buses totals 492: 6v + 13b = 492 (equation 2)

Subtract 2 times equation 2 from equation1, we get 14b = 420.

Thus, b = 30.

Since 12v + 12b = 564, plugging in b=30, 12v + (12)(30) = 564, so v = 17.

The number of students filled in the van is 17, and number of students filled in the bus is 30.

It is defined as the relation between two variables if we plot the graph of the linear equation we will get a straight line.

If in the linear equation one variable is present then the equation is known as linear equation in one variable.

Let's suppose the total number of students in van is x, and the number of students in the bus is y

Now for the first scenario we can frame a linear equation in two variables such as:

12x + 12y = 564 or

x + y = 47  ....(1)  (divide by 12 on both sides)

For the second scenario the linear equation in two variables becomes:

6x + 13y = 492 ....(2)

From the equation (1) take the value of x and plug in the equation (2), we get:

6(47-y) + 13y = 492

282 - 6y +13y = 492

7y = 492-282   (subtract 282 from both sides)

7y = 210

y = 30

Put this value in the equation (1), we get:

x + 30 = 47

x = 17   (subtract by 30 from both sides)

Thus, the number of students filled in the van is 17, and number of students filled in the bus is 30.

Y- intercept; when the value of X=0 so,

Given:

The equation is:

[tex]\dfrac{x+1}{x-1}-\dfrac{x-1}{x+1}=\dfrac{7}{12}[/tex]

To find:

The value of x.

Solution:

Formulae used:

[tex](a+b)^2=a^2+2ab+b^2[/tex]

[tex](a-b)^2=a^2-2ab+b^2[/tex]

[tex](a-b)(a+b)=a^2-b^2[/tex]

We have,

[tex]\dfrac{x+1}{x-1}-\dfrac{x-1}{x+1}=\dfrac{7}{12}[/tex]

Taking LCM, we get

[tex]\dfrac{(x+1)^2-(x^2-1)^2}{(x-1)(x+1)}=\dfrac{7}{12}[/tex]

[tex]\dfrac{x^2+2x+1-(x^2-2x+1)}{x^2-1^2}=\dfrac{7}{12}[/tex]

On cross multiplication, we get

[tex]12(x^2+2x+1-x^2+2x-1)=7(x^2-1)[/tex]

[tex]12(4x)=7x^2-7[/tex]

[tex]48x=7x^2-7[/tex]

[tex]0=7x^2-48x-7[/tex]

Splitting the middle term, we get

[tex]7x^2-49x+x-7=0[/tex]

[tex]7x(x-7)+1(x-7)=0[/tex]

[tex](7x+1)(x-7)=0[/tex]

[tex]x=-\dfrac{1}{7},7[/tex]

Therefore, the values of x are [tex]-\dfrac{1}{7}[/tex] and [tex]7[/tex].

[tex]\mathfrak{\huge{\orange{\underline{\underline{AnSwEr:-}}}}}[/tex]

Actually Welcome to the concept of areas,

we know that, area of rectangle = length * width,

here, length = x-2 and width = x-1

hence, area = (x-2) (x-1)

==> area = x^2 -x -2x +2

==> Area = x^2 - 3x + 2

hence the Option D.) is correct

Answer: its cubic

Step-by-step explanation:

The graph below is an example of a cubic type of function. Option C is correct.

A function is a statement, rule, or law that specifies the connection between two variables. Functions are common in mathematics and are required for the formulation of physical connections.

1. A parabola is the graph of a quadratic function. As a result, the presented graph is not a quadratic function graph.

2. A straight line is represented by a linear function. As a result, the presented graph is not a linear function graph.

3. A cubic function's end behavior is opposite at both ends. We can see that the presented graph satisfies these requirements.

4. A square root function's graph resembles a half parabola. As a result, it can't be the graph of the square root function.

The graph below is an example of a cubic type of function.

Hence,option C is correct.

Answer:

Colton solved 9 math problems and read 18 pages.

Answer:

353

Step-by-step explanation:

95 - 10 + 2(141 - 7)

following PEMDAS we will do parenthesis first

95 - 10 + 2(134)

multiplication is next

95 - 10 + 268

addition and subtraction are interchangeable when using PEMDAS but you do whatever comes first. since it's subtraction first in this equation we will do 95 - 10.

85 + 268

now we are left with addition

85 + 268 = 353

The integral expression of the form ∫ f(x) · dg is equal to the composite expression f(x) · g(x) - ∫ g(x) df by applying integration by parts method. (Correct choice: A)

In this question we must derive a integration rule for the product of two functions that are integrable. The integration by parts method is inspired on the differentiation rule for the product of two differentiable functions, whose definition is shown below:

[tex]\frac{d}{dx} [f(x)\cdot g(x)] = f'(x) \cdot g(x) + f(x)\cdot g'(x)[/tex]    (1)

If we integrate and used integral Calculus theorem on both sides of (1), then we have the following expression:

f(x) · g(x) = ∫ g(x) · df + ∫ f(x) · dg

∫ f(x) · dg = f(x) · g(x) - ∫ g(x) df    

Therefore, the integral expression of the form ∫ f(x) · dg is equal to the composite expression f(x) · g(x) - ∫ g(x) df by applying integration by parts method. (Correct choice: A)

Answer:

-35

Step-by-step explanation:

[tex]-5 = \frac{1}{7}a\\-35 = a[/tex]

I got this by multiplying the numerator by 7. This allows the denominator to be the same as the numerator, thus equalling 1.

1 * a = a

Answer: a = -35

Step-by-step explanation:

1. -5 = 1/7(a) || GIVEN

2. -5 * (7) = (7) * 1/7(a) || Isolate "a" on one side of the equation by multiplying 7 to the other side.

3. -35 = a
