Answer:

[tex]\:c_{11}=-2,\:\:\:c_{12}=-2[/tex]

[tex]\:c_{21}=5,\:\:\:c_{22}=8[/tex]

Step-by-step explanation:

Given the matrices

[tex]A=\begin{pmatrix}1&-1\\ 2&1\end{pmatrix}[/tex]

[tex]B=\begin{pmatrix}1&2\\ \:3&4\end{pmatrix}[/tex]

Calculating AB:

[tex]\begin{pmatrix}1&-1\\ \:\:2&1\end{pmatrix}\times \:\begin{pmatrix}1&2\\ \:\:3&4\end{pmatrix}=\begin{pmatrix}c_{11}&c_{12}\\ \:\:\:c_{21}&c_{22}\end{pmatrix}[/tex]

Multiply the rows of the first matrix by the columns of the second matrix

                                   [tex]=\begin{pmatrix}1\cdot \:1+\left(-1\right)\cdot \:3&1\cdot \:2+\left(-1\right)\cdot \:4\\ 2\cdot \:1+1\cdot \:3&2\cdot \:2+1\cdot \:4\end{pmatrix}[/tex]

                                   [tex]=\begin{pmatrix}-2&-2\\ 5&8\end{pmatrix}[/tex]

Hence,

[tex]\begin{pmatrix}c_{11}&c_{12}\\ \:\:\:c_{21}&c_{22}\end{pmatrix}=\begin{pmatrix}-2&-2\\ \:5&8\end{pmatrix}[/tex]

Therefore,

[tex]\:c_{11}=-2,\:\:\:c_{12}=-2[/tex]

[tex]\:c_{21}=5,\:\:\:c_{22}=8[/tex]

No

Answer:

Table 3

Step-by-step explanation:

In a proportional relationship there must be a constant rate of change.

The first table:

6-5 / 9-7 = 1/2

5-3 / 7-4 = 2/3

These are not equal so it is not proportional.

The second table:

10-8 / 150-120 =2/30

8-5 / 120-75 = 3/45

These are not equal so it is not proportional

The third table:

10-8 / 12-10 =2/2 = 1

8-6 / 10-8 =2/2 = 1

These are equal so this table is proportional.

Step-by-step explanation:

Answer: [tex]y-4=-\frac{1}{2} (x-6)[/tex]

Step-by-step explanation:

The point-slope form is y-y₁=m(x-x₁). y₁ and x₁ are from a point, and m is slope.

To find slope, we use the formula [tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex].

[tex]m=\frac{4-9}{6-(-4)}=\frac{-5}{10}=-\frac{1}{2}[/tex]

Now that we have the slope, we can fill in our point-slope form equation.

[tex]y-4=-\frac{1}{2} (x-6)[/tex]

Answer:

  b)  dx/dt = -2dy/dt

Step-by-step explanation:

We are given that ...

  x(t) +2y(t) = k

for some functions x(t) and y(t) and some constant k.

Differentiating with respect to time gives ...

  x'(t) +2y'(t) = 0

  x'(t) = -2y'(t) . . . . . subtract the y term

In the form used in the answer choices:

  dx/dt = -2dy/dt . . . . . matches choice B

Answer:

16

Step-by-step explanation:

let x be the unknown

1/8x =16/8

1/8x =2

x=8×2

x=16

The value of 1/8 times equals 16/8 will be 16.

Expression in maths is defined as the collection of numbers variables and functions by using signs like addition, subtraction, multiplication, and division.

Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbols, which can also be used to indicate the logical syntax's order of operations and other features.

Given that 1/8 times, what equals 16/8. Let x be the unknown. Let the unknown number be x. The value of x will be calculated as below:-

1/8x =16/8

1/8x =2

x=8×2

x=16

Therefore, the value of 1/8 times equals 16/8 will be 16.

Answer:

3/5 would be the answer.

Answer:

65

Step-by-step explanation:

Just use the Pythagorean theorem.

[tex]\boxed{a^2+b^2=c^2}[/tex]

[tex]33^2 + 56^2 = c^2\\1089 + 3136 = c^2\\4225 = c^2\\c = \sqrt{4225} \\c= 65[/tex]

Answer:

Third side is 65

Step-by-step explanation:

FORMULA

a^2 + b^2 = c^2

PLUG IT IN

33^2 + 56^2 = c^2

33 and 56 are the legs of the triangle so they go into the A and B variable.

The legs make up the right angle.

C is the hypotenuse, and here it is the diagonal line in that image.

FIND THE NUMBERS SQUARED

1089 + 3136 = c^2

ADD THEM TOGETHER

4225 = c^2

SQUARE ROOT BOTH SIDES

[tex]\sqrt{4225}[/tex] = ([tex]\sqrt{C}[/tex])^2

65 = c

CHECK

33^2 + 56^2=65^2

1089 + 3136 = 4225

4225 = 4225

Answer:

3/4 bucket

Step-by-step explanation:

Elle placed a bucket under a leaky roof. The bucket was 3/10 full after 2/5 of an hour. How much water is leaking per hour

Water leaking : time taken

Let x = amount of water leaking per hour

3/10 : 2/5 = x : 1

3/10 ÷ 2/5 = x / 1

3/10 × 5/2 = x / 1

15 / 20 = x / 1

Cross product

15 * 1 = 20 * x

15 = 20x

x = 15/20

= 3/4

3/4 bucket of water is leaking per hour

Answer:

The possible zeros/roots of the polynomial are

[tex]x = 0\\x=-\sqrt{3} \\ x=\sqrt{3}[/tex]

Step-by-step explanation:

[tex]h(x)=5x^3 - 5x - 10x[/tex]

[tex]h(x)=5x^3 -15x[/tex]

[tex]h(x)=5x(x^2 -3)[/tex]

When [tex]y= 0[/tex]

[tex]0=5x(x^2 -3)[/tex]

[tex]5x = 0 \implies x = 0[/tex]

[tex]x^2 - 3 = 0 \implies x=\pm\sqrt{3}[/tex]
