A. 10
B. 4
C. 7
D. 5

Answer:

F. (-4, oo)

Step-by-step explanation:

Start from the left side.

The arrow on the left side shows that the graph continues increasing forever as x decreases. Beginning at the highest value of y you see on the left side at point (-6, 5), as x increases, moving right along the x-axis, the y-values decrease. When you get to x = -4, y is at its lowest value which is 1.

Starting just to the right of x = -4, the y-values begin to increase from the lowest y-value of 1. The arrowhead at the right side top shows that the curve continues increasing forever to infinity.

The values of x for which y increases are all values greater than -4 and all the way to positive infinity.

This function is increasing for x > -4.

Now we need to write x > -4 in interval notation.

In interval notation, use a curved parenthesis to mean a number that is not included. The interval starts at -4, so it starts as

(-4

Then you write a comma to separate from the value where the interval ends.

(-4,

The interval in x of increasing values goes to positive infinity, so now you write the infinity symbol, and you close the interval with a curved parenthesis. By convention, infinity always gets a curved parenthesis. Also, I'll use oo for infinity below.

(-4, oo)

Answer:

Amrita's number is 6

Step-by-step explanation:

x               Double the unknown number

2x             Add 9

2x + 9       Divide the answer by 3

2/3x + 3   Subtract 1

2/3x + 2   Set this equal to the original number

2/3x + 2 = x

-2/3x       -2/3x   Subtract 2/3x from both sides

2 = 1/3x   Multiply both sides by 3

6 = x

Amrita's number was 6.

An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.

Example: 2 + 3x + 4y = 7 is an expression.

We have,

Number = x

We can write an expression from the given statement.

{ (2x + 9) ÷ 3 } - 1 = x

Solve for x.

{ (2x + 9) ÷ 3 } - 1 = x

(2x + 9)/3 - 1 = x

2x + 9 - 3 = 3x

Add 3 on both sides.

2x + 9 =  3x + 3

Subtract 9 on both sides.

2x = 3x + 3 - 9

2x = 3x - 6

6 = 3x - 2x

x = 6

We can cross-check.

{(2 x 6 + 9) ÷ 3} - 1 = 6

{(12 + 9) ÷ 3} - 1 = 6

7 - 1 = 6

6 = 6

Thus,

The number was 6.

Assume that f is one-to-one, meaning that every element in x maps to a unique element in y. Since |x| > |y|, there must exist at least one element in x that does not have a unique element in y to map to. Therefore, f cannot be one-to-one.

To prove this more formally, we can use the pigeonhole principle. Since |x| > |y|, there are more elements in x than there are elements in y. If f is one-to-one, then each element in x must map to a unique element in y. However, since there are more elements in x than there are in y, there must be at least one element in x that maps to the same element in y as another element in x. This violates the definition of a one-to-one function, and thus f cannot be one-to-one.

In simpler terms, when we have more pigeons (elements in x) than pigeonholes (elements in y), at least one   must have more than one pigeon. Similarly, when we have more elements in x than in y, at least one element in x must map to the same element in y as another element in x. Therefore, f cannot be one-to-one.

Step-by-step explanation:

By unitary method, we get that the total cost of mixture per pound = 50 cents.

A single unit's value can be determined from the values of multiple units, and multiple units' values can be determined from the values of single units using the unitary method.

Given:

Cost of 1 pound sunflower seeds = 32 cents.

Cost of 1 pound cracked corn = 18 cents.

Available sunflower seeds = 10lb = 10 pounds

Available cracked corn = 16lb = 16 pounds

To find: Cost of the mixture per pound

Finding:

By unitary method, Cost of 1 pound sunflower seeds = 32 cents.

Cost of 10 pounds sunflower seeds = 32(10) = 320 cents.

Again, by unitary method,

Cost of 1 pound cracked corn = 18 cents.

Cost of 16 pound cracked corn

= 18(16) cents

= 288 cents.

Therefore, total cost of mixture per pound

= 32 + 18 = 50 cents.

Answer: 3 1/4 + 7

Step-by-step explanation:

1/2 = 2/4 + 3/4 = 5/4/ 1 1/4 + 2 = 3 1/4 + 7

Step-by-step explanation:

a)

it all starts with the right-angled triangle at the bottom, under the seat row plane. it gives us the length of the tilted line from the front wall to row A, which is the baseline (Hypotenuse) for that triangle.

we know the bottom line (5.6 m). we know the angle at the left vertex (12°), and because the angle on the ground right underneath row A is 90°, the angle at row A is

180 - 90 - 12 = 78°

Hypotenuse/sin(90) = bottom line/sin(78)

Hypotenuse = 5.6/sin(78) = 5.725107331... m

the outside angle at the bottom left vertex is the inside angle of the same vertex for the triangle above the tilted floor. and that is the complementary angle to 12° (= 90-12 = 78°).

so the length of the line of sight from row A to the bottom of the screen (= side c) is then for the triangle above the tilted floor :

c² = 2.5² + 5.725107331...² - 2×2.5×5.72...×cos(78) =

= 33.07527023...

c = 5.751110347... m

so, we see, the length of the line of sight is slightly different to the length of the tilted floor. it is not an isoceles triangle.

the angle at the vertex at the bottom of the screen we get with the same method (this time we have all sides and need the angle) :

5.725107331...² = 2.5² + 5.751110347...² - 2×2.5×5.75...×cos(C)

cos(C) = -(5.725107331...² - 2.5² - 5.751110347...²)/(2×2.5×5.75...) = 0.227727026...

C = 76.8367109...°

the angle of elevation is then based on a horizontal line from row A

180 - 90 - 76.8367109... = 13.1632891...° ≈ 13.2°

b)

now we need to do the same things for row P.

the bottom line is now 19.6 m.

the angles still the same as before for the bottom triangle :

12° at the left bottom vertex, 90° in the ground under row P, 78° at the vertex directly at row P.

the length of the tilted floor (Hypotenuse) is then

Hypotenuse/sin(90) = 19.6/sin(78) = 20.03787566... m

the outside angle at the bottom left vertex is also the same as before. the complementary angle to 12° (= 90-12 = 78°).

so the length of the line of sight from row P to the bottom of the screen (= side c) is then for the triangle above the tilted floor :

c² = 2.5² + 20.03787566...² - 2×2.5×20.03...×cos(78) =

= 386.9359179...

c = 19.67068677... m

the angle at the vertex at the bottom of the screen we get with the same method (this time we have all sides and need the angle) :

20.03787566...² = 2.5² + 19.67068677...² - 2×2.5×19.75...×cos(C)

cos(C) = -(20.03787566...² - 2.5² - 19.67068677...²)/(2×2.5×19.67...) = -0.084700073...

C = 94.85877813...°

the angle of depression is then based on a horizontal line from row P

94.85877813... - 90 = 4.858778132...° ≈ 4.9°

why does this look different to the case in a) ?

because we are looking down instead of up, we have to compare it now to the outside supplementary angle at the bottom vertex of the screen (we are building another triangle on top of the line of sight) :

180 - 94.85877813... = 85.14122187...°

and our angle of depression is

180 - 90 - 85.14122187... = 4.858778132...° (see above).

The angle of elevation from Row A to the bottom of the screen is 78⁰.

The angle of depression from Row P to the bottom of the screen is 7.5⁰.

The angle of elevation from Row A to the bottom of the screen is calculated as follows;

from row A to the bottom of the screen, is a straight line;

angle elevation of row A to bottom of screen = 90 - 12⁰ = 78⁰

The length of row A to row P is calculated as;

cos 12 = L/19.6 m

L = 19.6 m x cos (12)

L = 19.2 m

The angle of depression from Row P to the bottom of the screen is calculated as follows;

sinθ = 2.5 m / 19.2 m

sinθ = 0.1302

θ = sin⁻¹ (0.1302)

θ =  7.5⁰

What is equation?

An equation is a statement in mathematics that states the equality of two expressions. It usually consists of variables, which are represented by letters and can take on different values, as well as constants and mathematical operations like addition, subtraction, multiplication, division, and exponentiation.

To solve x² = 16, we need to find the value of x that makes the equation true.

One way to solve this equation is to take the square root of both sides. However, it's important to remember that the square root of a number can be positive or negative, so we need to include both solutions:

√x² = √16

The level of measurement for the temperature of refrigerators cannot be determined based on the given information. The temperature could potentially be measured on a nominal scale if the refrigerators were categorized into different temperature ranges. However, without further context, it is not possible to determine the specific level of measurement.

The horsepower of race car engines can be measured on a ratio scale. Ratio scales have a meaningful zero point and allow for meaningful comparisons of values, such as determining that one engine has twice the horsepower of another.

The marital status of school board members can be measured on a nominal scale. Nominal scales are used for categorical data without any inherent order or ranking. Marital status categories, such as "married," "single," "divorced," etc., can be assigned to school board members.

The ratings of television programs, such as "poor," "fair," "good," and "excellent," can be measured on an ordinal scale. Ordinal scales represent data with ordered categories or ranks, but the differences between categories may not be equal or measurable.

The ages of children enrolled in a daycare can be measured on an interval scale. Interval scales have equal intervals between values, allowing for meaningful differences and comparisons. Age, measured in years or months, can be represented on an interval scale.

The behavior of the graph of the function y = -x^3 - 5x^2 - 3x + 9 at each of its zeros is as follows:

At x ≈ -4.919 and x ≈ -0.488, there are local minima.

At x ≈ 1.752, there is a local maximum.

Let's analyze the behavior of the graph of the function y = -x^3 - 5x^2 - 3x + 9 at each of its zeros in more detail.

To find the zeros of the function, we need to solve the equation -x^3 - 5x^2 - 3x + 9 = 0.

To simplify the calculations, let's use a numerical method like the Newton-Raphson method to approximate the zeros. We'll start with initial guesses and iteratively refine them to improve the accuracy of the solutions.

Initial guess: x_0 ≈ -5

Applying the Newton-Raphson method:

x_1 = x_0 - f(x_0) / f'(x_0)

where f(x) = -x^3 - 5x^2 - 3x + 9

f'(x) = -3x^2 - 10x - 3 (derivative of f(x))

x_1 = -5 - (-5^3 - 5(-5)^2 - 3(-5) + 9) / (-3(-5)^2 - 10(-5) - 3)

≈ -4.919

Initial guess: x_0 ≈ -1

Applying the Newton-Raphson method:

x_1 = x_0 - f(x_0) / f'(x_0)

x_1 = -1 - (-1^3 - 5(-1)^2 - 3(-1) + 9) / (-3(-1)^2 - 10(-1) - 3)

≈ -0.488

Initial guess: x_0 ≈ 2

Applying the Newton-Raphson method:

x_1 = x_0 - f(x_0) / f'(x_0)

x_1 = 2 - (2^3 - 5(2)^2 - 3(2) + 9) / (-3(2)^2 - 10(2) - 3)

≈ 1.752

After iterating through the Newton-Raphson method, we approximate the zeros as follows:

x ≈ -4.919

x ≈ -0.488

x ≈ 1.752

Now, let's analyze the behavior of the graph at each zero:

x ≈ -4.919:

When x is close to -4.919, y is close to zero. Since the coefficient of the leading term (-x^3) is negative, as x approaches -4.919 from the left side, the graph of the function will be decreasing. As x approaches -4.919 from the right side, the graph will be increasing. Therefore, the behavior of the graph near x ≈ -4.919 is a local minimum.

x ≈ -0.488:

When x is close to -0.488, y is close to zero. Similarly, as x approaches -0.488 from the left side, the graph will be decreasing, and as x approaches -0.488 from the right side, the graph will be increasing. Therefore, the behavior of the graph near x ≈ -0.488 is also a local minimum.

x ≈ 1.752:

When x is close to 1.752, y is close to zero. In this case, as x approaches 1.752 from the left side, the graph will be increasing, and as x approaches 1.752 from the right side, the graph will be decreasing. Therefore, the behavior of the graph near x ≈ 1.752 is a local maximum.

Your answer would be right side of the graph

Please mark as brainiest

The peak in the data would likely be the right side of the graph.

The distribution of a data set when displayed on a dot plot is said to be skewed left (left skewed) when most of the data appear on the right side of the graph. This means, the highest scores are on the right while the lowest values of the variable are on the left side of the graph (in order words, tapers towards the left of the graph). See the image labelled A in the attachment below.

Also, for a data set distribution that is skewed right (right skewed), most of the data appear on the left side of the graph. It will have a tail tapering to the right. See the image labelled A in the attachment below.
