Answer:

{ x | -3 <= x < +1 }

Step-by-step explanation:

We note that the graph occupies from x=-3 to x=+1, while -3 is a value included (endpoint is solid), and +1 is excluded (endpoint hollow).

Thus the domain is { x | -3 <= x < +1 }

Answer:  [tex]X+Y=\begin{pmatrix}9&2\\ -8&-1\end{pmatrix}[/tex]

Step-by-step explanation:

Given:  [tex]X=\begin{pmatrix}3&-5\\ -4&2\end{pmatrix},\ \ Y=\begin{pmatrix}6&7\\ -4&-3\end{pmatrix}[/tex]

To calculate: [tex]X+Y[/tex]

Consider [tex]X+Y= \begin{pmatrix}3&-5\\ -4&2\end{pmatrix}+\begin{pmatrix}6&7\\ -4&-3\end{pmatrix}[/tex]

[tex]=\begin{pmatrix}3+6&\left(-5\right)+7\\ \left(-4\right)+\left(-4\right)&2+\left(-3\right)\end{pmatrix}\\\\=\begin{pmatrix}9&2\\ -8&-1\end{pmatrix}[/tex][[tex]\mathrm{Add\:the\:corresponding\: elements\: and\: simplify}[/tex]]

Hence, [tex]X+Y=\begin{pmatrix}9&2\\ -8&-1\end{pmatrix}[/tex]

Answer:

The hypotenuse is 10 cm long.

Step-by-step explanation:

We can find the hypotenuse by using the following formula where "c" is the length of the hypotenuse and "a" and "b" are the lengths of the legs.

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

Now we just substitute the values and get...

[tex]c = \sqrt{a^{2} + b^{2} }\\c = \sqrt{6^{2} + 8^{2} } \\c = \sqrt{36 + 64} \\c = \sqrt{100} \\c = 10[/tex]

Therefore the hypotenuse is 10 cm long.

Answer:

a) 33289

b) £131.88

Step-by-step explanation:

→ To find the meter reading add the July reading to the units used

32347 + 942 = 33289

→ Multiply the unit price by the units used

0.14 × 942 = 131.88

Answer:

Just as the square root is a number that, when squared, gives the radicand, the cube root is a number that, when cubed, gives the radicand. Cubing a number is the same as taking it to the third power: 23 is 2 cubed, so the cube root of 23 is 2.

Step-by-step explanation:

there i hope you understood

The graphs of Square root function only continues in one direction forever whereas the cube root function continues in two directions forever.

"The principal square root function [tex]f(x) = \sqrt{x}[/tex] (usually just referred to as the "square root function") is a function that maps the set of non negative real numbers onto itself."

"The cube root function [tex]f(x) = \sqrt[3]{x}[/tex]  is a continuous function, with no start or end point. Its domain is all real numbers."

The similarities  in the graphs of square root function and cube root function are positive function (0,∞), x-intercept: intersects x-axis at (0, 0)

y-intercept: intersects y-axis at (0, 0).

The square root function only utilizes the positive square root. If both positive and negative square root values were used, it would not be a function. The cube root function can process  both positive and negative values.

Hence, the graphs of Square root function only continues in one direction forever whereas the cube root function continues in two directions forever.

Step-by-step explanation:

d = 6 cm

r = d : 2

= 6 : 2

= 3 cm

h = 10 cm

= 3.14 × 3 × 3 × 10

= 282.6 cm³

Answer:

669.9 ft³

Step-by-step explanation:

The formula for volume of a cone:

[tex]v=\pi r^2*\frac{h}{3} (3.14*radius*radius*\frac{height}{3} )[/tex]

[tex]r = radius,\pi =pi,h=height.[/tex]

The radius is 8; the height is 10.

From here, we can just plug the numbers into the formula.

[tex]\pi 8^2*\frac{10}{3} (3.14*8*8*\frac{10}{3} ) = 669.866666667.[/tex]

[tex]669.866666667[/tex] ≈ [tex]669.9.[/tex]

Answer:

y = 2x - 8

Step-by-step explanation:

y = 2x + b

-2 = 2(3) + b

-2 = 6 + b

-8 = b

Answer:

Let's analyze the example first:

We have:

3, 4, 6      target 42    answer: (3 + 4)*6

If we solve the equation, we get:

(3 + 4)*6 = 7*6 = 42

So, we need to reorder the first 3 numbers in an expression, such that the solution of the expression is the target number.

a) 2, 5, 6     Target 40

We know that 5*8 = 40

and that 2 + 6 = 8

Then the answer is:

(2 + 6)*5

b) 3, 4, 6  target 12

Here we know that 4*3 = 12

and 6 - 3 = 3

Then the answer is:

(6 - 3)*4

c) 4, 6, 10   target 1.

We know that the quotient of two equal numbers is 1.

And 4 + 6 = 10

Then the answer here is:

(4 + 6)/10

d) 3, 5, 6 target 21

We know that 3*5 = 15

And 15 + 6 = 21

Then the answer here is:

3*5 + 6

e) 2, 7, 10  target 6.

Here is a harder one.

We know that 2*3 = 6

And that 10 - 7 = 3

Then the answer ere is:

2*(10 - 7)

f) 3, 6, 15   target  3

Here we can use:

(15 - 6) = 9

And 9/3 = 3

Then the answer is:

(15 - 6)/3
