How many times can 45 go into 7,200?

Answer:

An identity matrix is a square matrix having 1s on the main diagonal, and 0s everywhere else. For example, the 2×2 and 3×3 identity matrices are shown below. These are called identity matrices because, when you multiply them with a compatible matrix , you get back the same matrix

Answer:

An identity matrix is a square matrix having 1s on the main diagonal, and 0s everywhere else. For example, the 2×2 and 3×3 identity matrices are shown below. These are called identity matrices because, when you multiply them with a compatible matrix , you get back the same matrix.

Identity Matrix is the matrix which is n × n square matrix where the diagonal consist of ones and the other elements are all zeros. It is also called as a Unit Matrix or Elementary matrix. It is represented as In or just by I, where n represents the size of the square matrix. Identity Matrix is denoted with the letter “In×n”, where n×n represents the order of the matrix.

One of the important properties of identity matrix is: A×In×n = A, where A is any square matrix of order n×n.

Answer:

x=13

Step-by-step explanation:

The two angles form a straight line so they add to 180 degrees

9x+17 + 3x+7 = 180

Combine like terms

12x +24 =180

Subtract 12 from each side

12x+24-24 =180-24

12x =156

Divide each side by 12

12x/12 =156/12

x=13

Answer:

x = 21

Step-by-step explanation:

equation:

⇒ 44 + 6x + 10 = 180

add like terms:

⇒ 44 + 6x + 10 = 180

⇒ 54 + 6x = 180

subtract 54 on both sides

⇒ 54 - 54 + 6x = 180 - 54

⇒ 6x = 126

divide 6 on both sides

⇒ [tex]\frac{6x}{6} = \frac{126}{6}[/tex]

⇒ x = 21

to check:

44 + (6x + 10) = 180

44 + (6 x 21 + 10) = 180

44 + 136 = 180

180 = 180

Answer:

[tex]\frac{2}{5}[/tex]

Step-by-step explanation:

Use the following equation:

slope (m) = [tex]\frac{y_2 - y_1}{x_2 - x_1}[/tex]

Let:

[tex](x_1 , y_1) = (4 , 4)\\(x_2 , y_2) = (9 , 6)[/tex]

Plug in the corresponding numbers to the corresponding variables:

m = [tex]\frac{6 - 4}{9 - 4} = \frac{2}{5}[/tex]

[tex]\frac{2}{5}[/tex] is your slope.

Answer:

[tex]m = \frac{2}{5} [/tex]

Step-by-step explanation:

Slope is equal to the change in y over the change in x, or rise over run.

[tex]m = \frac{change \: in \: y}{cahnge \: in \: x} [/tex]

The change in x is equal to the difference in x-coordinates  and the change in y is equal to the difference in y-coordinates.

[tex]m = \frac{y2 - y1}{x2 - x1} [/tex]

Substitute in the values of x and y into the equation to find the slope.

[tex]m = \frac{4 - (6)}{4 - (9)} [/tex]

Simplify.

[tex]m = \frac{2}{5} [/tex]

Therefor, the answer is m = 2/5.

Answer: 1386 sq.cm.

Step-by-step explanation:

2Pi r= 132

2 * 22/7 * r = 132

r = 21

Area = pi * r * r

= 22/7 * 21 * 21

= 1386 sq.cm.

Answer:

The derivative is:

[tex]f^{\prime}(x) = -\frac{5}{x^2-6x+9}[/tex]

Step-by-step explanation:

We are given the following function:

[tex]f(x) = \frac{5}{3-x}[/tex]

Derivative of a quotient:

Suppose we have a quotient:

[tex]f(x) = \frac{g(x)}{h(x)}[/tex]

The derivative is:

[tex]f^{\prime}(x) = \frac{g^{\prime}(x)h(x) - h^{\prime}(x)g(x)}{h(x)^2}[/tex]

In this question:

Numerator [tex]g(x) = 5, g^{\prime}(x) = 0[/tex]

Denominator [tex]h(x) = 3 - x, h^{\prime}(x) = -1[/tex]

So

[tex]f^{\prime}(x) = \frac{0(3-x) - 5}{(3 - x)^2} = -\frac{5}{x^2-6x+9}[/tex]

The derivative is:

[tex]f^{\prime}(x) = -\frac{5}{x^2-6x+9}[/tex]

Answer:

u(12-v)

Step-by-step explanation:

12u and -uv both have a factor of u in common, so we can pull it out to give us the factored expression u(12-v).

Note on factoring:

Remember, it's just using the distributive property in reverse! We can get our original expression back by distributing the u to the 12 and the -v.

Answer:

In exponential growth, the rate of growth is proportional to the quantity present. In other words, y′=ky. Systems that exhibit exponential growth have a constant doubling time, which is given by (ln2)/k. Systems that exhibit exponential decay have a constant half-life, which is given by (ln2)/k

Step-by-step explanation:

There is your answer good luck! - Alexsys

Answer:

In some cases with exponential functions, as the value of x increases, the value of y also increases. This is a direct relationship known as exponential growth. As the value of x increases, the value of y grows rapidly. ... This is an inverse relationship known as decay.
