Answer:

(A) The basis for the kernel of T is option (c) {(2, 0, 4), (-1, 1, 0), (0, 1, 1)}.

(B) The basis for the image of T is option (e) {(2, 0, 4), (1, -1, 0)}.

Step-by-step explanation:

(A) To find a basis for the kernel of T, we need to find vectors (x1, x2, x3) that satisfy T(x1, x2, x3) = (0, 0, 0). These vectors will represent the solutions to the homogeneous equation T(x1, x2, x3) = (0, 0, 0).

By setting each component of T(x1, x2, x3) equal to zero and solving the resulting system of equations, we can find the vectors that satisfy T(x1, x2, x3) = (0, 0, 0).

The system of equations is:

-2x1 - 2x2 + x3 = 0

2x1 + 2x2 - x3 = 0

8x1 + 8x2 - 4x3 = 0

Solving this system, we find that x1, x2, and x3 are not independent variables, and we obtain the following relationship:

x1 + x2 - 2x3 = 0

Therefore, a basis for the kernel of T is the set of vectors that satisfy the equation x1 + x2 - 2x3 = 0. Option (c) {(2, 0, 4), (-1, 1, 0), (0, 1, 1)} satisfies this condition and is a basis for the kernel of T.

(B) To find a basis for the image of T, we need to determine the vectors that result from applying T to all possible vectors (x1, x2, x3).

By computing T(x1, x2, x3) and examining the resulting vectors, we can identify a set of vectors that span the image of T. Since the vectors in the image of T should be linearly independent, we can then choose a basis from these vectors.

Computing T(x1, x2, x3), we get:

T(x1, x2, x3) = (-2x1 - 2x2 + x3, 2x1 + 2x2 - x3, 8x1 + 8x2 - 4x3)

From the given options, option (e) {(2, 0, 4), (1, -1, 0)} satisfies this condition and spans the image of T. Therefore, option (e) is a basis for the image of T.

The problem involves determining the basis for the kernel and image of a linear transformation T on ℝ³. Therefore, the correct answer for the basis of the image of T is option (e).

(A) To find the basis for the kernel of T, we need to determine the vectors that are mapped to the zero vector by T. These vectors satisfy the equation T(x₁, x₂, x₃) = (0, 0, 0).

By analyzing the options, we find that option (d) {(-1, 0, -2), (-1, 1, 0)} represents a basis for the kernel of T. This is because if we substitute these vectors into T, we obtain the zero vector (0, 0, 0).

Therefore, the correct answer for the basis of the kernel of T is option (d).

(B) To find the basis for the image of T, we need to determine the vectors that can be obtained by applying T to different vectors in ℝ³.

By analyzing the options, we find that option (e) {(2, 0, 4), (1, -1, 0)} represents a basis for the image of T. This is because any vector in the image of T can be expressed as a linear combination of these two vectors.

The ratio of the probability of flipping a tail to the probability of flipping a head when the probability of getting three heads is the same as the probability of getting exactly two tails in three flips is 1/3.

Let p be the probability of flipping a head and q be the probability of flipping a tail.

The probability of getting three heads in three flips is \((p)^3.\)

The probability of getting exactly two tails in three flips is 3pq².

Given that these probabilities are equal, we have:

\((p)^3\)= 3pq²

Simplifying this equation gives:

p = 3q

Dividing both sides by q gives:

p/q = 3

Therefore, the ratio of the probability of flipping a tail to the probability of flipping a head is 1/3.

A firm experiences increasing returns to scale if inputs are doubled and output more than doubles.

When the firm's output grows at a faster rate than the growth in inputs, increasing returns to scale result. In this case, the company experiences economies of scale, which makes it more effective as it grows its production.

The firm is able to boost productivity and efficiency as it expands its scale of operations if inputs are doubled and output more than doubles.

This can be ascribed to a number of things, including specialisation, labour division, the use of capital-intensive technology, discounts for bulk purchases, and spreading fixed costs over a higher output. Lower average costs per unit of output result in higher profitability and competitiveness for the company.

The firm gains a number of benefits from growing returns to scale. First off, it lets the company to benefit from cost savings brought about by economies of scale, allowing it to manufacture goods or services for less money per unit.

Answer:

Step-by-step explanation:

Let us suppose that length of Triangle is equal to x.

that is

Length = x

Than

width = x - 10

perimeter of Rectangle is

2(length) + 2(width) = 36

2x + 2(x-10) = 36

2x +2x - 20 = 36

4x -20 = 36

4x = 36 +20

4x = 56

x = 56/4

x = 14

so Length of Rectangle is 14 inches

and

width = x - 10

width = 14 - 10

width = 4

The element of this group is {0, 1, 2, 3, ...., 25}, this group is a cyclic group, and 16 is not a generator for this group but 5 is a generator for this group.

\(Z_{26}\) ≡ Group of integers under addition modulo 26

addition modulo is all addition of integer in ordinary way than remove integral multiple. For example, addition modulo a+mb is a+b than remove all integral multiple m and the result is lower than m (residue).

a) The elements of this group is all the integers remainder after mod 26. So,

x = k (mod 26) where 0 ≤ k < 26

or we can write each of them as {0, 1, 2, ..., 23, 24, 25}

b) Cyclic group is a group that is generated by 1 element. Since, the group is integers under addition modulo with all integers can be generated by adding 1 repeatedly, so the group \(Z_{26}\) is cyclic group.

c) As 1 ∈ \(Z_{26}\) but there is no m ∈ N such that \(16^m\) = 1, but for \(5^m\) is

or in simply way, we can say there is m ∈ N for \(5^m\) = 1. So, 16 is not generator of this group, but 5 is generator of this group.

Thus, the number of {0, 1, 2, 3, ...., 25} is the element for this group, cyclic group is a type of this group, and 5 is a generator for this group but 16 is not a generator for this group.

The equation of the triangle's line of symmetry is Y= X+10.

Equation: The definition of an equation is a mathematical statement that shows that two mathematical expressions are equal. For instance, 3x + 5 = 14 is an equation, in which 3x + 5 and 14 are two expressions separated by an 'equal' sign.

Symmetry: Symmetry means that one shape is identical to the other shape when it is moved, rotated, or flipped. If an object does not have symmetry, we say that the object is asymmetrical. The concept of symmetry is commonly found in geometry.

Isosceles triangle is a triangle that has at least two sides of equal length. Sometimes it is specified as having exactly two sides of equal length, and sometimes as having at least two sides of equal length, the latter version thus including the equilateral triangle as a special case.

It is given that an isosceles triangle with sides A(-10,1) ; B (-6,3) ; C(-4,7) is drawn and we notice that, the mid point of AB is the perpendicular bisector of the line AB.

Mid point of AB = (-8,2)

Slope of AB = [(-10) - (-6)] / (1 - 3)

=> -4 / -2

=> 2

Slope of perpendicular bisector of AB = 1

Equation of the line of symmetry = (Y - 2) = 1 [X - (-8)]

=> Y - 2 = X + 8

=> Y= X+10

Therefore, the equation of the triangle's line of symmetry is Y= X+10.
