(a) True

(b) True

(c) False

(d) True

(e) False

(a) True. For any n × n invertible matrix A, the equation Ax = 0 admits only the trivial solution. This is because if A is invertible, then there exists an inverse matrix A^-1 such that A^-1A = I, where I is the identity matrix. Therefore, if Ax = 0, then A^-1Ax = A^-10, or x = 0. This means that the only solution to the equation is the trivial solution x = 0.

(b) True. For any two matrices A and B of size n × n, (AB)^T = (B^T) (A^T). This is a property of matrix multiplication and transposition, and can be easily verified by performing the operations on the matrices.

(c) False. Let A be a matrix of size n × n. If for two vectors y and z of R^n we have Ay = Az, it does not necessarily mean that y = z. It is possible for two different vectors to produce the same result when multiplied by the same matrix. For example, consider the matrix A = [[1, 0], [0, 1]] and the vectors y = [1, 0] and z = [0, 1]. Both Ay and Az will result in the same vector [1, 1], but y and z are clearly not equal.

(d) True. If A is a matrix of size n × n such that A^3 = I(n), then A is invertible. This is because A^3 = I(n) implies that A^2 = A^-1, meaning that the inverse of A exists and A is invertible.

(e) False. For any two matrices A and B of size n×n such that AB = 0, it is not necessarily true that A = 0 or B = 0. It is possible for two non-zero matrices to multiply to produce the zero matrix. For example, consider the matrices A = [[1, -1], [1, -1]] and B = [[1, 1], [1, 1]]. Both A and B are non-zero matrices, but AB = 0.

The given system of equations is:

3x + 2y + 4z - w = 13

-2x + y + 5z = 5

We can write this system in the form of an augmented matrix as:

| 3 2 4 -1 | 13 |

| -2 1 5 0 | 5 |

To transform this matrix to echelon form, we perform the following elementary row operations:

Add 2 times the first row to the second row:

| 3 2 4 -1 | 13 |

| 0 5 13 -2 | 31 |

Divide the second row by 5 to obtain a leading 1:

| 3 2 4 -1 | 13 |

| 0 1 13/5 -2/5 | 31/5 |

Subtract 4 times the second row from the first row:

| 3 0 -6/5 3/5 | 9/5 |

| 0 1 13/5 -2/5 | 31/5 |

Multiply the second row by 6/5 and add it to the first row:

| 3 0 0 16/5 | 57/5 |

| 0 1 13/5 -2/5 | 31/5 |

The matrix is now in echelon form. Using back substitution, we can solve for the variables:

From the second row, we have:

y + (13/5)z - (2/5)w = 31/5

y = (2/5)w - (13/5)z + 31/5

Substituting y in the first row, we have:

3x + 2[(2/5)w - (13/5)z + 31/5] + 4z - w = 57/5

3x + (4/5)w - (26/5)z = 2/5

Solving for x, we have:

x = (2/15)w + (26/15)z - 2/15

So the solution is:

x = (2/15)w + (26/15)z - 2/15

y = (2/5)w - (13/5)z + 31/5

z = z

w = w

This is a parametric solution, as we have one free variable (z) and can express the other variables in terms of it. Therefore, the system has infinitely many solutions.

Answer:

1 mile is equal to 1,760 yards. Therefore, 3 miles is equal to 3 x 1,760 = 5,280 yards.

Comparing 5,280 yards to 1,000 yards, we can see that 5,280 yards is greater than 1,000 yards.

To determine how much greater, we can subtract 1,000 from 5,280:

5,280 - 1,000 = 4,280

Therefore, 3 miles is 4,280 yards greater than 1,000 yards.

The sin of the angle is 0.6 and the cos of the angle is 0.8.

In a right triangle, the sine (sin) of an angle is the ratio of the length of the side opposite to the angle to the length of the hypotenuse. The cosine (cos) of an angle is the ratio of the length of the side adjacent to the angle to the length of the hypotenuse.

In this case, the side opposite to the angle is 6 and the side adjacent to the angle is 8. To find the hypotenuse, we can use the Pythagorean theorem:

a^2 + b^2 = c^2

Where a and b are the lengths of the two legs of the right triangle, and c is the length of the hypotenuse.

Plugging in the given values:

6^2 + 8^2 = c^2

36 + 64 = c^2

100 = c^2

c = 10

So the hypotenuse of the right triangle is 10.

Now we can find the sin and cos of the angle:

sin = opposite/hypotenuse = 6/10 = 0.6

cos = adjacent/hypotenuse = 8/10 = 0.8

Therefore, the sin of the angle is 0.6 and the cos of the angle is 0.8.

Using Algebraic expression we concluded, In practice, the angle of the pendulum may not be exactly equal to the calculated values due to factors such as air resistance, friction, and variations in the length of the pendulum.

What is Algebraic expression ?

A combination of variables and constants is an algebraic expression.

We can see that the pendulum's height drops with each swing if we make the assumption that each swing is measured from the same starting point.

Using a sequence is one technique to mathematically express this data. Assuming that n = 1, 2, 3, 4, let's define the sequence "a n" as the pendulum's height on the nth swing. Then, we could type:

a_1 = 80

a_2 = 76

a_3 = 72.2

a_4 = 68.59

Another way to represent this information is by using a formula that describes the height of the pendulum on each swing. One common formula for the height of a simple pendulum is:

[tex]h = L - L\times cos(\theta)[/tex]

where h is the height of the pendulum, L is the length of the pendulum, and θ is the angle that the pendulum swings from its resting position. Assuming that the length of the pendulum remains constant, we can use this formula to find the angle θ for each swing:

For the first swing, h = 80 cm, L = constant, so we can solve for θ:

[tex]80 = L - L\times cos(\theta)\\cos(\theta) = 1 - 80/L\\\theta = arccos(1 - 80/L)[/tex]

For the second swing, we have h = 76 cm, so we can use the same formula with h = 76 and solve for θ:

[tex]76 = L - L\times cos(\theta)\\cos(\theta) = 1 - 76/L\\\theta = arccos(1 - 76/L)[/tex]

Similarly, we can use the formula to find θ for the third and fourth swings:

For the third swing, h = 72.2 cm:

θ = arccos(1 - 72.2/L)

For the fourth swing, h = 68.59 cm:

θ = arccos(1 - 68.59/L)

Therefore, in practice, the angle of the pendulum may not be exactly equal to the calculated values due to factors such as air resistance, friction, and variations in the length of the pendulum.

The quadratic equation (c+5)²=36 will give c = 1,-11.

A quadratic equation is a type of equation in algebra that involves a variable (usually denoted as "x") raised to the power of 2, or squared. The standard form of a quadratic equation is:

ax² + bx + c = 0

where a, b, and c are constants, with a≠0. The goal is to solve for the variable x, which may have one or two possible solutions depending on the coefficients of the equation.

Now,

To solve the equation (c + 5)² = 36:

Taking the square root of both sides of the equation

√(c + 5)² = ±√36

Simplify the left-hand side using the rule that √a² = |a|:

|c + 5| = ±6

Solve for c in each case by subtracting 5 from both sides of the equation:

c + 5 = 6 or c + 5 = -6

Solve for c in each equation:

c = 1 or c = -11

Therefore, the solutions to the equation (c + 5)² = 36 are c = 1 and c = -11.

Answer:

Step-by-step explanation:

The empirical rule states that for a normal distribution, approximately 68% of the data falls within one standard deviation of the mean. Therefore, to find the interval of hours that represents the lifespan of the middle 68% of light bulbs, we need to find the interval that is one standard deviation away from the mean in either direction.

Since the mean is 1400 hours and the standard deviation is 50 hours, we can use the following formula to find the interval:

(mean - standard deviation, mean + standard deviation)

Plugging in the values, we get:

(1400 - 50, 1400 + 50)

Simplifying, we get:

(1350, 1450)

Therefore, the interval of hours that represents the lifespan of the middle 68% of light bulbs is from 1350 hours to 1450 hours.

Answer:

(1350,1450)

Step-by-step explanation:

The Empirical Rule states that 68% of data points fall within one standard deviation of the mean. So, subtract 50 from the mean and add 50 to the mean to find the lifespan of the middle 68% of bulbs.

The given relation that is a function is the fourth graph which shows a U- shaped curve.

The graph of a quadratic function is a U-shaped curve called a parabola, which can either face upwards or downwards depending on the value of "a". If "a" is positive, the parabola faces upwards, and if "a" is negative, the parabola faces downwards.

The coefficient "a" determines the width and direction of the parabola, while the constants "b" and "c" determine its position on the coordinate plane. This therefore shows that the fourth graph is a function.

The cost Analysis for the two proposed plans for building a low ultra-light bicycle concluded on the recommendation that d that Bici Bicycle Company follow the first plan.

The first plan involves a cost of $125,000 to design and build a prototype bicycle. The combined materials and labor costs for each bike made under the first plan will be $225. This means that for every bike Bici Bicycle Company produces under the first plan, it will incur a total cost of $350 ($125,000 + $225).

On the other hand, the second plan involves a cost of $100,000 to design and build the prototype. The combined materials and labor costs for each bike made under the second plan will be $275. This means that for every bike Bici Bicycle Company produces under the second plan, it will incur a total cost of $375 ($100,000 + $275).

Therefore, while the second plan has a lower initial cost of prototype development, it will ultimately result in a higher cost per unit produced. The first plan, although it has a higher initial prototype development cost, will ultimately result in a lower cost per unit produced.

To determine the break-even point, we can set the total cost of producing a bike under each plan equal to each other and solve for the number of bikes produced.

For the first plan:

Total cost = $125,000 + ($225 x n)

For the second plan:

Total cost = $100,000 + ($275 x n)

Setting these equal to each other, we get:

$125,000 + ($225 x n) = $100,000 + ($275 x n)

$25,000 = $50 x n

n = 500

Therefore, Bici Bicycle Company would need to produce at least 500 bicycles for the cost per unit of the first plan to be less than that of the second plan.

In conclusion, based on my analysis, I would recommend that Bici Bicycle Company follow the first plan, as it will ultimately result in a lower cost per unit produced. However, if the company anticipates producing fewer than 500 bicycles, the second plan may be more cost-effective.

The vertices of the image of the triangle BCD are B'(x, y) = (- 3, 13), C'(x, y) = (0, 19) and D'(x, y) = (18, 10). The representation of the resulting figure is in the image attached below.

Herein we find the representation of a triangle on Cartesian plane, whose image, that is, the result of a dilation, must be found. The formula to be used is introduced below:

P'(x, y) = P(x, y) + k · [P(x, y) - O(x, y)]

Where:

If we know that B(x, y) = (- 3, 7), C(x, y) = (- 2, 9), D(x, y) = (4, 6), O(x, y) = (- 3, 4) and k = 2, then the coordinates of the vertices of the image are listed below:

B'(x, y) = (- 3, 7) + 2 · [(- 3, 7) - (- 3, 4)]

B'(x, y) = (- 3, 7) + 2 · (0, 3)

B'(x, y) = (- 3, 7) + (0, 6)

B'(x, y) = (- 3, 13)

C'(x, y) = (- 2, 9) + 2 · [(- 2, 9) - (- 3, 4)]

C'(x, y) = (- 2, 9) + 2 · (1, 5)

C'(x, y) = (- 2, 9) + (2, 10)

C'(x, y) = (0, 19)

D'(x, y) = (4, 6) + 2 · [(4, 6) - (- 3, 4)]

D'(x, y) = (4, 6) + 2 · (7, 2)

D'(x, y) = (4, 6) + (14, 4)

D'(x, y) = (18, 10)

Best describes the translation of the figure moves Left and down.

A translation is a transformation that moves every point of a figure or object by the same distance and in the same direction without changing its shape, size, or orientation. It is a type of rigid transformation that preserves the distance between points and angles between lines.

A translation can be described using the horizontal and vertical shift or displacement of the object. If a point (x, y) is translated by a distance of 'a' units to the right and 'b' units upwards, the new location of the point would be (x + a, y + b).

Question says that a figure is translated using the mapping (x, y) → (x + a, y + b).

If the value of 'a' is negative and the value of 'b' is negative in the mapping (x, y) → (x + a, y + b), it means that the figure is being translated to the left and downwards.

The x-coordinates are being decreased by the absolute value of 'a', which means that the figure is moving left. Similarly, the y-coordinates are being decreased by the absolute value of 'b', which means that the figure is moving downwards.

Therefore, the best description of the translation is "the figure moves left and down"

The vertex of a parabola (1.75, -0.25). The vertical intercept of a parabola is (0, 11). The two intercepts of the parabola ((7 + √5)/4, 0) and ((7 - √5)/4, 0).

A) The vertex of a parabola is given by the formula (h, k), where h = -b/2a and k = f(h). In this case, a = 4, b = -14, and c = 11. So, h = -(-14)/2(4) = 14/8 = 1.75. Plugging this value back into the equation, we get k = f(1.75) = 4(1.75)^2 - 14(1.75) + 11 = -0.25. Therefore, the vertex of the parabola is (1.75, -0.25).

B) The vertical intercept is the point where the parabola crosses the y-axis, which occurs when x = 0. Plugging this value into the equation, we get f(0) = 4(0)^2 - 14(0) + 11 = 11. Therefore, the vertical intercept is the point (0, 11).

C) The two intercepts of the parabola are the points where it crosses the x-axis, which occur when f(x) = 0. We can use the quadratic formula to find these values:

x = (-b ± √(b^2 - 4ac))/2a

x = (-(-14) ± √((-14)^2 - 4(4)(11)))/2(4)

x = (14 ± √(196 - 176))/8

x = (14 ± √20)/8

x = (14 ± 2√5)/8

x = (7 ± √5)/4

Therefore, the two intercepts are the points ((7 + √5)/4, 0) and ((7 - √5)/4, 0).

There could be many other combinations of scores that would result in the same mean, median, and mode.

What is mean ?

Mean can be defined as ratio sum of given observations, total number of observations.

Since the median is 7 and the mode is 8, we can assume that the majority of her scores were in the range of 7-8 points. We can also assume that there were a few games in which she scored lower than 7 points and a few games in which she scored higher than 8 points.

Here's one possible set of scores that would result in a mean of 6, a median of 7, and a mode of 8:

Game 1: 3 points

Game 2: 5 points

Game 3: 6 points

Game 4: 7 points

Game 5: 7 points

Game 6: 8 points

Game 7: 8 points

Game 8: 8 points

Game 9: 9 points

Game 10: 10 points

Game 11: 11 points

Note that this is just one possible set of scores that would fit the given statistics.

Therefore, There could be many other combinations of scores that would result in the same mean, median, and mode.
