The quadrant in which the point (-11, -22) lies is the third (3rd) quadrant.

In Mathematics, a quadrant can be defined as the area that is occupied by the values on the x-coordinate (x-axis) and y-coordinate (y-axis) of a cartesian coordinate in a graph.

This ultimately implies that, there are four (4) major quadrants in any graph and these include the following:

Generally speaking, the coordinates of the third (3rd) quadrant are all negative, which simply means that both the x-values and y-values are negative e.g (-11, -22).

The inequality's sign will indicate which half-plane to shade, unless you are graphing a vertical line. Shade above the line if either the or > symbol is present. Shade below the line if the symbol "or" is used. When a linear inequality contains the symbols "less than" or "less than or equal to," you should shade below the boundary line. In a linear inequality, you will shade above the boundary line if the symbol is > (greater than) or (greater than or equal to).

The fraction of time Vincent was able to play basketball today is 2/3 of the usual amount of time Vincent plays basketball everyday.

Fraction of time Vincent plays basketball everyday = 4/5 of an hour

1 hour = 60 minutes

Time Vincent plays basketball everyday = 4/5 of 60

= 4/5 × 60

= 48 minutes

Vincent played basketball today for 32 minutes

Fraction of time Vincent plays basketball everyday = x of 38 minutes

32 = x × 48

32 = 48x

x = 32/48

x = 4/6

x = 2/3

Therefore, Vincent was able to play basketball for 2/3 of 48 minutes today.

Answer:

y = unknown number

3 < y < 8

Step-by-step explanation:

Let x and y be the two natural numbers

x - y > 6  and  x - y < 11

6 < x - y < 11

x is still positive after y amount is taken away from it. Since y is part of x, x is the greater value.

Hence, x=14:

6 < 14 - y < 11  ==> solve for y, the missing value

-8 < -y < -3  ==> subtract 14 on all sides

8 > y > 3  ==> Since each side is being divided by -1, switch the inequality  

                signs since the numbers are being divided by a negative number

3 < y < 8  ==> rearrange the inequality

To solve the equation 2c - 3 = 2(6 - c) + 7c, option 1: Distribute and collect like terms on each side is done.

What is an equation?

A mathematical definition of an equation is a claim that two expressions are equal when they are joined by the equals sign ("=").

The given equation is 2c−3=2(6−c)+ 7c.

To solve the equation first use the distributive property to multiply 2 by 6-c.

2c - 3 = 12 - 2c + 7c

Next, combine the like terms -2c and 7c to get 5c.

2c - 3 = 12 + 5c

Now, subtract 5c from both left-hand side and right-hand side.

2c - 3 - 5c = 12 - 5c

Next, combine the like terms 2c and -5c to get -3c.

- 3 - 3c = 12

Now, add 3 to both left-hand side and right-hand side.

- 3 - 3c + 3 = 12 + 3

Next, on right-hand side add 12 and 3 to get 15.

- 3c = 15

Now, divide both left-hand side and right-hand side by -3.

(-3c)/-3 = 15/-3

The result is obtained as -

c = -5

Therefore, the solution for the equation is c = -5.

The probability of getting at least 6 heads is3/256 or 0.0117

Probability shows possibility to happen an event, it defines that an event will occur or not. The probability varies from 0 to 1.

Simply put, probability is the likelihood that something will occur. When we don't know how an event will turn out, we might discuss the likelihood or likelihood of several outcomes. Statistics is the study of occurrences that follow a probability distribution.

Probability is a measure of how likely something is to occur. Calculating probability involves dividing the total number of outcomes by the number of possible ways an event may occur.

Given that,

A fair coin is tossed = 8 time.

We have to find the probability of getting at least 6 heads.

Since, the probability of getting head, when one coin is tossed = 1/2

And the probability of getting tale = 1/2  

The probability of getting head at least  6 times when coin is tossed 8 times can be given as,

The head can come 6 times, then probability = [tex](1/2)\x^{6} (1/2)\x^{2}[/tex] =  (1/2)⁸

The head can come 7 times, then probability = (1/2)⁷(1/2) = (1/2)⁸

The head can come 8 times, then probability = (1/2)⁸

The probability of getting head at least 6 times

= (1/2)⁸ + (1/2)⁸ +  (1/2)⁸ = 3(1/2)⁸ = 3/256 = 0.0117

The correct domain for the set, D = { -2, -4, 2}.

The range of values that we are permitted to enter into our function is known as the domain of a function. The x values for a function like f make up this set (x). A function's range is the collection of values it can take as input. After we enter an x value, the function outputs this sequence of values.

Given:

We have the set = {(-2,5), (-4, 1)(2, 12)}

We know that the domain is usually the input value

Answer:just add them all together!!

Step-by-step explanation:

Answer: Solving the first one. Feel free to ask questions!

Step-by-step explanation:

Area - number of units inside a given shape (Your using this one)

Perimeter - number of units to cover the outside

Step 1: Determine the needed formulas. In this case, there are 2 rectangles, so we will use Width X Height to solve

Step 2: Break the shape into simple shapes to solve

Step 3: Solve

  Solving purple rectangle: 8 is the width, and the height is 2

       8 x 2 = 16

 Solving pink rectangle: 4 is the height, and 5 is the width

       4 x 5 = 20

Step 4: Once all areas are found, add them together

       16 + 20 = 36        36 is the total Area

_______________________________________________________

Problem 2

Again there are 2 rectangles, so we will use Width X Height to solve

Step 2: Break the shape apart

Step 3: Solve

   Solving blue rectangle: 2 is the width, 3 is the height

        2 x 3 = 6

   Solving green rectangle: 7 is the width, 3 is the height

        7 x 3 = 21

Step 4: Add

        6 + 21 = 27       27 is the total Area

* Remember, Every shape has a given formula to find the area*

Answer:

Step-by-step explanation:

To find the equation of a line passing through two points, we can use the slope-point form:

y - y1 = m(x - x1)

where (x1, y1) is one of the points on the line, m is the slope of the line and can be calculated as

m = (y2 - y1) / (x2 - x1)

where (x2, y2) is the second point on the line.

Given the points (-6, -5) and (4, -3), we can substitute the values into the slope formula to find m:

m = (-3 - (-5)) / (4 - (-6)) = 2 / 10 = 1/5

Next, we can substitute the point (-6, -5) and the slope 1/5 into the slope-point form to find the equation of the line:

y - (-5) = 1/5 (x - (-6))

y + 5 = 1/5 x + 6

5y + 25 = x + 30

5y = x + 5

y = (x + 5) / 5

Thus, the equation of the line passing through the points (-6, -5) and (4, -3) is y = (x + 5) / 5.

The change Δf is 0.462, value of the estimate is 0.4 and the approximation error is 0.062.

A function is a relation from a set A to a set B where the elements in set A only maps to one and only one image in set B. No elements in set A has more than one image in set B.

Given function is,

f(x) = 2x³ - 2x

x₀ = 1 and dx = 0.1

(a) f(x₀) = f(1) = 2 - 2 = 0

f(x₀ + dx) = f(1.1) = 2 (1.1)³ - (2 × 1.1) = 0.462

Δf = f(x₀ + dx) - f(x₀) = 0.462 - 0 = 0.462

(b) Value of the estimate is,

f'(x) = 6x² - 2

f'(x₀) = f'(1) = 6 - 2 = 4

df = f'(x₀) dx = 4 × 0.1 = 0.4

(c) Approximation error is,

| Δf - df | = | 0.462 - 0.4 | = 0.062
