1. The dimensions of A are 6 x 4.

2. The function is S could be onto, but it cannot be one-to-one.  (C)

1. This is because T: R4 → R6 is a matrix transformation that maps from a 4-dimensional space to a 6-dimensional space. Therefore, the matrix A must have 6 rows and 4 columns in order to be able to multiply with a 4-dimensional vector x and produce a 6-dimensional vector T(x).

2. This is because S: R3 → R2 is a matrix transformation that maps from a 3-dimensional space to a 2-dimensional space.

This means that there are more input vectors than there are output vectors, so it is not possible for S to be one-to-one. However, S could be onto if every vector in R2 can be obtained from some vector in R3 through the transformation S(x) = Bx.

104 consumers bought at least one of the three labels, 12 consumers bought labels A and B but not C 44 consumers bought label A and 91 consumers bought none of these labels because of the equations.

To find the number of consumers who buy the product sold under at least one of the three labels, we need to add up the number of consumers who buy the product under each label individually and those who buy the product under multiple labels.

However, we need to be careful not to double count those who buy the product under all three labels. Therefore, the formula for this calculation is:

At least one of the three labels = (A only) + (B only) + (C only) + (A and B only) + (A and C only) + (B and C only) + (A, B, and C)

Plugging in the given values, we get:

At least one of the three labels = 15 + 20 + 28 + 12 + 9 + 12 + 8 = 104 consumers

To find the number of consumers who buy the product sold under labels A and B but not C, we simply use the value given for those who buy only those sold under labels A and B:

Labels A and B but not C = 12 consumers

To find the number of consumers who buy the product sold under label A, we need to add up the number of consumers who buy the product under label A individually and those who buy the product under label A and one or both of the other labels. Therefore, the formula for this calculation is:

Label A = (A only) + (A and B only) + (A and C only) + (A, B, and C)

Plugging in the given values, we get:

Label A = 15 + 12 + 9 + 8 = 44 consumers

Finally, to find the number of consumers who buy the product sold under none of these labels, we subtract the number of consumers who buy the product under at least one of the three labels from the total number of consumers surveyed:

None of these labels = Total consumers - At least one of the three labels = 195 - 104 = 91 consumers

Step-by-step explanation:

Check the picture below.

Answer:

Let's start by using the information given in the problem to write an equation for the perimeter of the rectangle:

Perimeter = 2(length + width)

We know that the length of the rectangle is twice its width, so we can write:

length = 2*width

Substituting this expression into the equation for the perimeter, we get:

Perimeter = 2(2*width + width)

Simplifying this expression, we get:

Perimeter = 6*width

We are given that the perimeter is 7 1/3 cm, which we can convert to a mixed number:

Perimeter = 7 + 1/3 = 22/3

Substituting this value into the equation above, we get:

22/3 = 6*width

Solving for the width, we get:

width = 22/3 ÷ 6 = 11/9

Now that we have the width, we can use the expression for the length to find its value:

length = 2*width = 2(11/9) = 22/9

Finally, we can use the formula for the area of a rectangle, A = length * width, to find the area:

A = (22/9) * (11/9) = 242/81 square cm

Therefore, the area of the rectangle is 242/81 square cm.

The simplified expression is -4x + 44/3.

An exponent is a numerical value that indicates how many times a number, variable, or expression is to be multiplied by itself. It is usually written as a superscript to the right of the base, such as in the expression 3², where 3 is the base and 2 is the exponent.

The exponent indicates that 3 is to be multiplied by itself 2 times, resulting in a value of 9. Exponents are used in many areas of mathematics, including algebra, calculus, and geometry, and are an important concept for understanding mathematical operations and functions.

To simplify the expression, we need to follow the order of operations and combine like terms where possible:

2/3(3x - 1) + 4x + 3² - 10x + 5

First, simplify the expression inside the parentheses:

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

Next, simplify the squared term:

3² = 9

Now, combine the like terms:

2x - 2/3 + 4x - 10x + 9 + 5 = -4x + 14 + 2/3

Finally, we can rewrite the expression with the fractional coefficient as a mixed number:

-4x + 14 + 2/3 = -4x + 44/3

Dividing the fraction (x - 2) / (3x - 21) by (5x - 10) / (9x - 63) will result to 3/5.

To divide two fractions, we need to multiply the first fraction by the reciprocal of the second fraction. The reciprocal of a fraction is simply the fraction flipped upside down. So, the reciprocal of the second equation (5x - 10) / (9x - 63) is (9x - 63) / (5x - 10). Now we can multiply the two fractions together to get the answer.

(x - 2) / (3x - 21) × (9x - 63) / (5x - 10)

= [(x - 2)(9x - 63)] / [(3x - 21)(5x - 10)]

Now we can simplify the numerator and denominator by factoring out the common factors:

Matrix A is diagonalizable

Yes, it is possible to test a matrix \( A \in M_{n \times n}(R) \) for diagonalizability. If \( A \) is diagonalizable, then there exists an invertible matrix \( Q \) and a diagonal matrix \( D \) such that \( A = Q D Q^{-1}\). To find these matrices, we can use the following steps:

1. Find the characteristic polynomial \( p(\lambda) \) of \( A \).
2. Find the eigenvalues of \( A \) by solving \( p(\lambda) = 0 \).
3. Find the corresponding eigenvectors for each eigenvalue of \( A \).
4. Construct the matrix \( Q \) as a matrix whose columns are composed of the eigenvectors of \( A \).
5. Construct the diagonal matrix \( D \) by placing the eigenvalues of \( A \) along the diagonal entries.

Step-by-step explanation:

In triangle ABC, measure of side BC or a is 8.8 unit

In trigonometry, the cosine rule states that the square of the length of any side of a given triangle is the sum of the squares of the lengths of the other sides minus twice the product of the other two sides multiplied by the cosine of angle included between them.

cosA = (b² + c² - a²)/2bc

Given,

In triangle ABC

A = 49° , b = 10, c = 11

By cosine rule

cosA = (b² + c² - a²)/2bc

cos49° = (10² + 11² - a²)/2(10×11)

0.656 = (100 + 121 - a²)/220
144.32 = 100 + 121 - a²

a² = 221 - 144.32

a² = 76.68

a = √76.68

a = 8.7567 ≈ 8.8

Answer:

-14 gallon jugs

- 10 half-gallon jugs

Step-by-step explanation:

I'm not an expert at solving these algebraically, so I'm going to do this the old-fashioned way: Guess and Check.

Lets sum up our information:

- He bought 19 gallons

- He bought those 19 gallons with 24 jugs

- There are half-gallon and full gallon jugs

We know that if he bought 24 full gallon jugs, he would have 24 gallons of milk, but he only has 19, so this is not the answer

We know that if he bought 23 full gallons jugs and one half-gallon jug, he would have 23.5 gallons of milk, but he only has 19 gallons of milk, so this is also not the answer.

We keep reducing the number of full gallon jugs and increasing the number of half-gallon jugs until we reach 19 gallons total.

After trying different combinations, we can figure out that he bought

-14 gallon jugs

- 10 half-gallon jugs

The principal is 50 and the rate of interest is 0.4.

The principal (P) and the rate of interest (R) can be calculated using the following equations:
P = (400*2)/(440 - 400)
R = (440 - 400)/(P*2)
Substituting the given values in the equations we get:
P = 2000/40 = 50
R = 40/100 = 0.4

To calculate the rate and principal of the sum of money, we can use the formula for simple interest: I = Prt, where I is the interest, P is the principal, r is the rate, and t is the time in years.
Given that the yearly interest for the first year is 400 and for the second year is 440, we can set up two equations:
400 = Prt
440 = Pr( t + 1)
Since the interest is for two consecutive years, the time in the first equation is t and the time in the second equation is t + 1.

We can rearrange the first equation to solve for P:
P = 400 / rt
Substituting this value of P into the second equation gives us:
440 = (400 / rt)( t + 1)
Simplifying and rearranging gives us:
440rt = 400t + 400
40rt = 400
rt = 10

Since we are looking for the rate and principal, we can substitute the value of rt back into the first equation:
400 = P(10)
P = 40
So the principal is 40 and the rate is 10 / t. To find the rate, we can substitute the value of P back into the first equation and solve for t:
400 = 40(10 / t)
t = 10
So the rate is 10 / 10 = 1.

t + 3b = 10.5 → (2)

multiplying (2) by - 2 and adding to (1) will eliminate t

- 2t - 6b = - 21 → (3)

add (1) and (3) term by term to eliminate t

- 4b = - 12 ( divide both sides by - 4 )

b = 3

substitute b = 3 into either of the 2 equations and solve for t

If Ella is 15 meters away from Mary and 9 meters away from Dante, then distance between Dante and Mary are 12 meters away from each other.

It is given that Ella is 9 meter away from Dante and in the Dante is in south of Ella. This means that if we consider a plane ground and mark the directions as north, south, east and west, Ella and Dante will be in north and south direction respectively. Since Mary is in the east direction of Dante, this means She will be in the South East direction of Ella and about 15 meters away from her. This creates a triangular connection between them.

Hence by applying the Pythagoras theorem, we get following equation:

The equation of the tangent line to the curve at the point (1, 3) is y = (3/2)x + 1/2.

To find the equation of the tangent line to the curve at a given point, we first need to find the slope of the tangent line at that point. We can do this by finding the derivative of the curve, which is given by y'(x) = 3x² / 2(2+x³)^(1/2).

Next, we need to find the coordinates of the point at which we want to find the equation of the tangent line. Let's say we want to find the equation of the tangent line at the point (1, 3).

Now, we can use the point-slope form of a line to find the equation of the tangent line. The point-slope form of a line is given by y - y1 = m(x - x1), where m is the slope of the line, and (x1, y1) is a point on the line.

Plugging in the values for the slope and the point, we get:

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

Simplifying the equation, we get:

y - 3 = (3/2)(x - 1)

y = (3/2)x + 1/2
