Our matrix C is the encoder.  Let X be our secret message and let B be our encoded message.  Therefore the relationship between the 3 can be represented as:

CX = B

So we want to solve for X (our secret message). So using matrix algebra:

X = C^-1*B

where C^-1 is the inverse of C.

C^-1 = | 3 -2 |

          |4 -3 |

So we take C^-1 and multiply it by matrix B to get X.  Matrix B is already given to us.  So just multiply those two.  I used a calculator to get:

X = | 20 8 5 3 15 12 15 |

What is meant by inequality?

In mathematics, inequalities specify the connection between two non-equal numbers. Equal does not imply inequality. Inequality is a mathematical statement that uses the inequality symbol to illustrate the relationship between two expressions. An inequality symbol has non-equal expressions on both sides. It indicates that the phrase on the left should be bigger or smaller than the expression on the right, or vice versa. Literal inequalities are relationships between two algebraic expressions that are expressed using the inequality symbols. Typically, we use the "not equal" sign to indicate that two values are not equal. However several inequalities are utilised to compare the numbers, whether it is less than or higher than.

Given the inequality,

8m + 95 < -87m +5

We are asked to solve the inequality.

this means we have to find the value of m.

8m + 95 < -87m +5

8m + 87m < 5 - 95

95m < -90

Path z is the longest path that leads to the lake.

An algebraic expression is a combination of numbers, variables, and mathematical operations such as addition, subtraction, multiplication, and division. It is a mathematical phrase that can contain one or more terms separated by mathematical operators.

For example, 3x + 4y - 2z is an algebraic expression that contains three terms: 3x, 4y, and -2z. Each term is made up of a coefficient and a variable, where the coefficient is the numerical value that multiplies the variable.

In algebraic expressions, variables are used to represent unknown values, and the expression can be evaluated by substituting known values for the variables. For instance, if x = 2, y = 3, and z = 1, then the expression 3x + 4y - 2z can be evaluated as 3(2) + 4(3) - 2(1) = 12.

Algebraic expressions can also include exponentiation, roots, and other advanced mathematical operations. They are widely used in mathematics and other fields, such as physics and engineering, to represent relationships between variables and to model real-world situations.

Let's start by assigning variables to each path:

Let x be the length of path x (in meters).

Then path y is 116 meters longer than path x, so its length is x + 116.

Path w is 51 meters shorter than path y, so its length is x + 116 - 51 = x + 65.

Path z is 85 meters longer than path w, so its length is x + 65 + 85 = x + 150.

To find the longest path, we need to compare the lengths of all four paths. We can do this by looking at the expressions we just derived:

Path x has length x.

Path y has length x + 116.

Path w has length x + 65.

Path z has length x + 150.

Since all four paths have a common component of x, the lengths of the paths can be compared by comparing the values of the expressions that add to x. We can see that x + 150 is the largest expression, which means that path z is the longest.

Therefore, path z is the longest path that leads to the lake.

Answer:

the wholesale discount is 28%.

Step-by-step explanation:

To find the wholesale discount, we need to calculate the difference between the retail price and the wholesale price as a percentage of the retail price. We can use the following formula:

Wholesale discount = ((Retail price - Wholesale price) / Retail price) x 100%

Substituting the given values into the formula, we get:

Wholesale discount = ((1320 - 950.40) / 1320) x 100%

Wholesale discount = (369.60 / 1320) x 100%

Wholesale discount = 0.28 x 100%

Therefore, the wholesale discount is 28%.

To write the answer as a whole number or an exact decimal, we can multiply 0.28 by 100 to get:

Wholesale discount = 28%

So the wholesale discount is 28%.

line a is 5ft

The length of q is approximately is 0.4 cm.

Trigonometry is a branch of mathematics that studies relationships between side lengths and angles of triangles.

To solve for the length of q in triangle AOPQ, we can use the law of sines, which states:

a/sin A = b/sin B = c/sin C

where a, b, and c are the lengths of the sides opposite the angles A, B, and C, respectively.

In triangle AOPQ, we know that:

Side p = 6.3 cm (opposite angle P)

Angle O = 149° (opposite side q)

Angle P = 29° (opposite side p)

Let use angle sum property of triangles to find the measure of angle Q:

Angle Q = 180° - Angle O - Angle P

Angle Q = 180° - 149° - 29°

Angle Q = 2°

Now we can use the law of sines to solve for the length of q:

q/sin Q = p/sin P

q/sin(2°) = 6.3/sin(29°)

q = sin(2°) × (6.3/sin(29°))

q=0.034 × (6.3/0.484)

q = 0.442 cm

Therefore, the length of q is approximately is 0.4 cm.

What is trigonometry ?

Trigonometry is a branch of mathematics that deals with the relationships and properties of angles and the trigonometric functions such as sine, cosine, and tangent. It is based on the study of the geometric properties of triangles and is used extensively in fields such as physics, engineering, architecture, and astronomy.

In trigonometry, the relationships between the sides and angles of a triangle are expressed using the six trigonometric functions: sine (sin), cosine (cos), tangent (tan), cosecant (csc), secant (sec), and cotangent (cot). These functions describe the ratios between the sides of a right triangle, where one angle is 90 degrees. Trigonometric functions can also be defined for any angle, not just those in a right triangle, using the unit circle or other methods.

Trigonometry has many practical applications, such as in navigation, surveying, and the design of structures such as bridges and buildings. It is also used extensively in science and engineering, particularly in fields such as physics, mechanics, and electromagnetics.

If tan x = 0, then tan(-x) = 0.

The tangent function is an odd function, which means that tan(-x) = -tan(x). However, since tan x = 0, this means that -tan(x) = 0 as well. Therefore, tan(-x) = 0.

If sin x = 0.3, then sin(-x) = -0.3.

The sine function is an odd function, which means that sin(-x) = -sin(x). Since sin x = 0.3, this means that -sin(x) = -0.3. Therefore, sin(-x) = -0.3.

If cos x = 0.3, then cos(-x) = 0.3.

The cosine function is an even function, which means that cos(-x) = cos(x). Since cos x = 0.3, this means that cos(-x) = 0.3 as well.

If tan x = -2, then tan(pi+x) = tan(pi + atan(-2)) = tan(2.0344 + pi) = -2.

To find tan(pi + x), we need to use the identity tan(a + pi) = -tan(a). In this case, a = atan(-2), which is the inverse tangent of -2. Using a calculator or a table, we can find that a is approximately 2.0344 radians. Therefore, tan(pi + x) = -tan(2.0344) = -(-2) = 2.

Answer:

Step-by-step explanation:

To obtain a polynomial of lowest degree with the given zeros and leading coefficient, we can use the fact that if a polynomial has a root of multiplicity m, then the factor (x - r)^m appears in the polynomial. Therefore, we can write:

f(x) = A(x + 1/4)^2(x - 2/3)

where A is a constant that we need to determine to satisfy the condition f(0) = 2.

To find A, we substitute x = 0 into f(x) and set the result equal to 2:

f(0) = A(0 + 1/4)^2(0 - 2/3) = -A/27 = 2

Solving for A, we find that A = -54.

Therefore, the polynomial f(x) is:

f(x) = -54(x + 1/4)^2(x - 2/3)

The equation of the ellipse in standard form is 16x² + 25y² = 400.

The standard form of the equation of an ellipse centered at the origin is:

x²/a² + y²/b² = 1

where a is the distance from the center to a vertex along the x-axis, and b is the distance from the center to a co-vertex along the y-axis.

In this case, we know that the center of the ellipse is at (0,0), a vertex is at (-5,0), and a co-vertex is at (0,4).

The distance from the center to a vertex along the x-axis is the absolute value of the x-coordinate of the vertex, which is 5. So, a = 5.

The distance from the center to a co-vertex along the y-axis is the absolute value of the y-coordinate of the co-vertex, which is also 4.

So, b = 4.

Substituting these values into the standard form equation, we get:

(x²/5²) + (y²/4²) = 1

Simplifying and multiplying by 5² and 4², we get the standard form equation of the ellipse:

16x² + 25y² = 400

Therefore, the equation of the ellipse in standard form is 16x² + 25y² = 400.

Answer:

Step-by-step explanation:

Pour trouver la forme standard de l'équation d'une ellipse à partir des extrémités des grands axes et des petits axes, nous pouvons utiliser les formules suivantes:

Le centre de l'ellipse est le point (h, k), où h est la moyenne des coordonnées x des extrémités des grands axes et k est la moyenne des coordonnées y des extrémités des petits axes. Donc,

h = (2 + 8) / 2 = 5

k = (3 + 1) / 2 = 2

Donc, le centre de l'ellipse est (5, 2).

La distance a est la moitié de la longueur du grand axe, donc

a = (8 - 2) / 2 = 3

La distance b est la moitié de la longueur du petit axe, donc

b = (3 - 1) / 2 = 1

Maintenant, nous pouvons utiliser ces valeurs pour écrire l'équation de l'ellipse en forme standard:

(x - h)^2 / a^2 + (y - k)^2 / b^2 = 1

En substituant les valeurs trouvées précédemment, nous avons:

(x - 5)^2 / 3^2 + (y - 2)^2 / 1^2 = 1

Step-by-step explanation:

To get 3 liters of milk, Toby has two options:

Option 1: Buy 6 half-liter containers

The cost of one half-liter container is $2.43, so the cost of six such containers is 6 x $2.43 = $14.58.

Option 2: Buy 12 250-milliliter containers

The cost of one 250-milliliter container is $1.42, which is equivalent to $5.68 per liter (since 1 liter is equal to 4 250-milliliter containers). Therefore, the cost of 3 liters (which is equivalent to 12 250-milliliter containers) is 12 x $1.42 = $17.04.

Therefore, Toby should buy 6 half-liter containers as it is the cheaper option.

Answer:

the probability of being dealt 5 cards from the same suit is approximately 0.00198, or about 0.198%.

Step-by-step explanation:

The total number of ways to choose 5 cards from a deck of 52 cards is given by the combination formula:

C(52, 5) = 52! / (5! (52 - 5)!) = 2,598,960

Now, we need to count the number of ways of choosing 5 cards from the same suit. There are 4 suits in a deck of cards (hearts, diamonds, clubs, and spades), so we need to count the number of ways to choose 5 cards from each of these suits and add them up.

For each suit, the number of ways of choosing 5 cards from that suit is given by the combination formula:

C(13, 5) = 13! / (5! (13 - 5)!) = 1,287

So the total number of ways of choosing 5 cards from the same suit is:

4 * 1,287 = 5,148

Therefore, the probability of getting 5 cards from the same suit is:

5,148 / 2,598,960 ≈ 0.00198

So the probability of being dealt 5 cards from the same suit is approximately 0.00198, or about 0.198%.

The domain are the possible input while the range are the possible output of a function.

(a) The domain = [-√2, √2], the range = [0, 2]

(b) The domain = [-1, 1], the range = [0, 1]

(d) The domain = [0, 2], the range = [0, 1]

(e) The domain = [-(2 + √2), (√2 - 2)], the range = [0, 2]

Reasons:

The given functions can be expressed by the equation; (-x + 1)·(x + 1) = -x² + 1

Therefore, we have;

(a) y = f(x) + 1 = -x² + 1 + 1 = -x² + 2

The x-intercept of the above function are, x = √2, and x = -√2

Which gives;

The domain = [-√2, √2]

The range = [0, 2]

(b) y = 3·f(x) = 3 × (-x² + 1) = -3·x² + 3

At the x–intercepts, we have;

-3·x² + 3 = 0

x = ±1

The domain = [-1, 1]

The maximum value of y is given at x = 0, therefore;

= -3 × 0² + 3 = 3

The range = [0, 1]

(c) y = -f(x) = -(-x² + 1) = x² - 1

At the x–intercepts, x² - 1 = 0

x = ± 1

The domain = [-1, 1]

The minimum value of y is given at x = 0, which is y = -1

The range = [0, -1]

(d) y = f(x - 1) = -(x - 1)² + 1 = -x² + 2·x

At the x–intercepts, we have;  -x² + 2·x = 0, which gives;

(-x + 2)·x = 0

Which gives, x = 0, or x = 2

The domain = [0, 2]

The maximum value of y is given when x = -b/(2·a) = -2/(2×(-1)) = 1

y = f(1) =  -1² + 2×1 = 1

Therefore;

The range = [0, 1]

(e) y = f(x + 2) + 1 = (-(x + 2)² + 1) + 1 = -x² - 4·x - 2

At the x–intercepts, we have;  -x² - 4·x - 2 = 0, which gives;

x = -(2 + √2) or x = x = √2 - 2

The domain = [-(2 + √2), (√2 - 2)]

The maximum value of y is given when x = -4/(2)) = -2

Which gives;

-(-2)² - 4·(-2) - 2 = 2

The range = [0, 2]

The solution has been obtained by using arithmetic operations.

What are arithmetic operations?

According to mathematicians, any real number may be expressed using the four basic operations, also referred to as "arithmetic operations." The four mathematical operations that produce quotient, product, sum, and difference, respectively, are divide, multiply, add, and subtract.

(a) We are given that Ann had a total of 285 red and blue beads, and she used 45 red beads and 40% of the blue bead.

Let the red beads be x and blue beads be y

So, we get

x + y = 285

x = 285 - y

After using the beads, we get another equation as

⇒(x - 45) / (y - 0.4y) = 1/3

⇒(285 - y - 45) / (y - 0.4y) = 1/3

⇒(240 - y) / (0.6y) = 1/3

⇒720 - 3y = 0.6y

⇒720 = 3.6y

⇒y = 200

So, x = 85

Blue beads used = 40% of 200 = 80

(b) Since, Ann has used 80 blue beads and 45 red beads, so

Beads in the end = 285 - 45 - 80 = 160

Hence, Ann had 160 beads in the end.
