Temperature is a physical quantity that expresses the hotness of matter or radiation. The heat increases an objects temperature.

Temperature is a physical quantity that expresses the hotness of matter or radiation.

The temperature of the object increases due to the absorbed part of the heat. An object decreases its temperature by releasing energy in the form of heat to its surroundings. And an object increases its temperature by gaining energy in the form of heat from its surroundings.

So the temperature changes according to the heat of the surrounding.

Therefore the heat increases an objects temperature.

[tex]\sqrt{4}[/tex], [tex]\sqrt{9}[/tex], [tex]\sqrt{16}[/tex]

Step-by-step explanation:

I think that you are asking for 3 examples of square roots that are rational.  All perfect squares are rational.  If the square root is not a perfect square then the number is irrational.

[tex]\sqrt{4[/tex] = 2 and -2.  The number multiplied by itself is an integer.  Integers are the whole numbers and their opposites: ...-3, -2, -1,  0, 1, 2, 3...  

1/2 is not an integers.  0.75 is not an integer.

[tex]\sqrt{9}[/tex]  is 3 and -3

The Domain is   [-4, -2] U  [-1, 1)  and range is [4, 0)

The domain of a function is the set of values that we are allowed to plug into our function.

The range of a function is the set of values that the function assumes.

Given:

The left piece has its other endpoint at x = -2.

So, the interval for the domain is [-4, -2] and the other part is [-1, 1)

So, the domain is [-4, -2] U  [-1, 1)

and the range is the vertical range of the right part.

So, range is [4, 0)

Answer: the answer is MO=5

Step-by-step explanation:

Answer:

This formula has no values, it is a false inequality. X can not be greater than 5, and less than 3.

Step-by-step explanation:

x < 3 or x > 5

This means, x is less than 3, but greater than 5.

Technically, you would write this as 5 < x < 3, however, this is a false inequality, and does not work.

Each of the pairs of opposite angles made by two intersecting lines are called a pair of vertical angles. The value of x is 13.

Each of the pairs of opposite angles made by two intersecting lines are called a pair of vertical angles.

Given that ∠A and ∠B are vertical angles. Therefore, the measure of the two of the given angle will be equal to each other. Thus, we can write the measure of the two angles as,

∠A = ∠B

(5x + 5)° = (6x - 8)°

5x + 5 = 6x - 8

Bring the like terms on the same side of the equation,

5 + 8 = 6x - 5x

13 = x

x = 13

The composition of the functions, f(g(-1)) = 2.

To find the composition of the functions, f(g(-1)), first, find the function, g(-1) by tracing the value of y that will give an x-value of -1 on the function graph.

The next step is to use the value you get in the first step to trace which value of y will give an x-value equivalent to what you got in the first step on the second function graph.

Thus, from the graph of g(x), g(-1) = 0. Using the graph of f(x), the value of y when x = 0 is 2.

Therefore, the composition of the functions, f(g(-1)) = 2.

The vertex of the quadratic function f(x) = (x + 3)² - 4 is (-3,-4)

Given a quadratic function, the equation of the quadratic function in vertex form is given by f(x) = a(x - h)² + k where

Now, given the quadratic function f(x) = (x + 3)² - 4, we require the vertex of the quadratic function.

Comparing the function f(x) = (x + 3)² - 4 with f(x) a(x - h)² + k, we see that

Since the vertex of the quadratic function is (h, k), we see that the vertex of the quadratic function f(x) is (-3,-4)

So, the vertex of the quadratic function is (-3,-4)

The system of nonlinear equations have two solutions: (x, y) = (0.114, 0.354), (x, y) = (1.432, 1.103).

In this problem we find a system of two nonlinear equations involving radical expressions. We proceed to resolve the system of nonlinear equations by algebra properties:

(2 · x - 1)² + 8√(2 · x · y) = 4

8√(2 · x · y) = 4 - (2 · x - 1)²

8√(2 · x · y) = 4 - 4 · x² + 4 · x - 1

8√(2 · x · y) = 4 · x - 4 · x² + 3

64 · (2 · x · y) = [(4 · x + 3) - 4 · x²]²

128 · x · y = (4 · x + 3)² - 8 · (4 · x + 3) · x² + 64 · x⁴

128 · x · y = 16 · x² + 24 · x + 9 - 32 · x³ - 24 · x² + 64 · x⁴            (1)

4 · y - √(8 · x · y - 1) = 1

4 · y - 1 = √(8 · x · y - 1)

(4 · y - 1)² = 8 · x · y - 1

16 · y² - 8 · y + 2 = 8 · x · y                                                             (2)

Now we plot two equations on a graphing tool and find that the system has the following two solutions: (x, y) = (0.114, 0.354), (x, y) = (1.432, 1.103).

gg=3.9 gigabytes

3.9 number of gigabytes of data William can use while staying within his budget.

Two or more expressions with an Equal sign is called as Equation.

Given,

William pays a flat cost of $54.50 per month and $3 per gigabyte.

He wants to keep his bill at $66.20 per month.

We need to solve this and to find number of gigabytes of data William can use while staying within his budget.

This can be written as equation

66.2=54.5+3gg

Subtract 54.5 from both sides

66.2=54.5+3gg

3gg=66.2-54.5

3gg=11.7

Divide both sides by 3

gg=3.9 gigabytes
