The image of an arbitrary vector [xy] under the linear transformation T is given by the vector [-11x - 9x + 56y].

To find the image of an arbitrary vector [xy] under the linear transformation T, we can use the linearity property of T.

Since T is a linear transformation, we have:

\(T([xy]) = T(xv_1 + yv_2)\)

Using the linearity property, we can expand this expression:

\(T([xy]) = xT(v_1) + yT(v_2)\)

Substituting the given values of \(T(v_1)\) and \(T(v_2)\), we get:

T([xy]) = x[-11-9] + y[56]

T([xy]) = [-11x - 9x + 56y]

Therefore, the image of an arbitrary vector [xy] under the linear transformation T is given by the vector [-11x - 9x + 56y].

The annual income of a certain household that has a z-score of 1.5, is 80,000.

The relationship between a value and a group of values' mean is described statistically by the Z-score. Standard deviations from the mean serve as the unit of measurement for Z-score. The score for a data point is equal to the mean score if the Z-score is 0. A value that deviates by one standard deviation from the mean is indicated by a Z-score of 1.0.

Z-scores can either be positive or negative, with a positive value indicating that the score is above the mean and a negative value indicating that the score is below the mean. Z-scores are measurements of an instrument's variability used in investing and trading that traders can use to estimate volatility.

Let the annual income be x.

x has μ = 50000, σ = 20000

We know that for given x, z = (x−μ)/σ

Given that z - score = 1.5

Substituting the values we get

⇒ 1.5 = (x−50000)/20000

​⇒ 1.5 × 20000 = x−50000

​⇒ 30000 = x − 50000

⇒ x = 30000 + 50000

⇒ x = 80,000

Thus, The annual income of a certain household that has a z-score of 1.5, is 80,000.

The expression z(x-3+y) simplifies to zx - 3z + zy. None of the provided options are equivalent, except for option c.

To simplify the expression z(x - 3 + y), we can distribute the z to each term inside the parentheses.

First, we distribute z to x: z * x = zx.

Next, we distribute z to -3: z * -3 = -3z.

Lastly, we distribute z to y: z * y = zy.

Putting it all together, we have zx - 3z + zy.

Comparing this expression to the options given, we see that the correct choice is c. zx - 3z + zy.

Option a. -3 + y is not equal to zx - 3z + zy because it lacks the term zx.

Option b. -3zx + y is not equal to zx - 3z + zy because it incorrectly multiplies -3 with zx instead of distributing z to x.

Option d. zx + 3z + zy is not equal to zx - 3z + zy because it adds an additional term 3z, which is not present in the original expression.

Therefore, the correct expression equal to z(x - 3 + y) is c. zx - 3z + zy.

Answer:

£42.04 is the correct answer.

Step-by-step explanation:

Cost of pack of 15 bread rolls = £1.91

Cost of pack of 20 cheese slices = £2.23

She has to buy exactly twice as many cheese slices as bread rolls.

She has to make more than 100 cheese sandwiches.

Number of bread rolls required for 100 bread rolls.

Minimum 15\(\times\)7 = 105 bread rolls are to be bought.

105 bread rolls mean 210 cheese slices but it is a pack of 20 cheese slices.

So, at least 220 cheese slices can be bought.

But, 220/2 = 110 bread rolls are not possible to be bought.

So, at least 120 (15 \(\times\) 8 i.e. 8 packs) bread rolls have to be bought and 120 \(\times\) 2 = 240 (20 \(\times\) 12 i.e. 12 packs) of sandwiches have to be bought.

So, minimum amount to be spent for at least 100 cheese sandwiches

= 1.91 \(\times\) 8 + 2.23 \(\times\) 12 = £42.04

Step-by-step explanation:

The sum of the interior angles of any quadrilateral is 360 degrees. Adding up the known measures gives you 95 + 123 + 62 = 280. Then you can subtract that from 360. 360 - 280 = 80. So x has to be 80 degrees.

Answer:

x=8

Step-by-step explanation:

2x+13 = -3x +53

Add 3x to each side

2x+13+3x = -3x+53+3x

5x+13 = 53

Subtract 13 from each side

5x+13-13 = 53-13

5x = 40

Divide by 5

5x/5 = 40/5

The value of the integral is 2pi.

To interpret the given integral in terms of areas, we need to recognize that the integrand, \(\sqrt(4-x^2),\) represents the upper half of a circle with radius 2 centered at the origin.

First, we can sketch the graph of\(y = \sqrt(4-x^2)\)over the interval [-2, 2]:

      |         /\            |

   2 |       /    \          |

      |      /        \       |

     |     /            \     |

     |_/_____  __\_|

         -2         2

The integral can be evaluated as follows:

\(int_(-2)^2 \sqrt(4-x^2) dx\) = area of upper half of circle with radius 2 and center at (0, 0)

                         = (1/2) * pi *\(r^2\), where r = 2

                         = (1/2) * pi * 4

                         = 2pi

Therefore, the value of the integral is 2pi.

The proportional relationship is the third table and table A.

For a proportional relationship, a straight line can be drawn through all points and the line passes through origin.

Proportions are defined as the concept where two or more ratios are set to be equal to each other.

If the ratios p : q and r : s are proportional, then we can write it as p : q = r : s or p/q = r/s.

A proportional relationship is there if we can write the relationship as y = k x, where k is a constant.

In the first question, the third table shows the proportional relationship.

When x = -2, y = 2 × -2 = -4

When x = -1, y = 2 × -1 = -2

When x = 1, y = 2 × 1 = 2

When x = 2, y = 2 × 2 = 4

This is a proportional relationship with k = 2.

In the second question, for table A, again the function is of the form y = 2x.

x = 1, then y = 2

x = 2, then y = 4

x = 3, then y = 6

x = 4, then y = 8

x = 5, then y = 10

When the relation is proportional, then the graph will be a straight line passing through all the points satisfying the equation.

Since y = kx, when x = 0, y = 0.

So the line passes through origin.

Hence the straight line can be drawn through all points and the line passes through origin.

The measure of the arc PR, m\(\widehat{PR}\), found using the properties of the interior angle of a right triangle is; m\(\widehat{PR}\) = 120°

A right triangle is a triangle that has an interior angle of 90°.

The two tangents to the circle, QP and QR indicates that the angle formed by the radius of the circle and the point of tangency are both 90°, therefore, the two triangles formed by the radii of the circle to the points of tangency are right angle triangles, with the vertex angles at the center of the circle of 90° - 60°/2 = 60° each.

The angle formed at the center of the circle by the two right triangles, which is the same as the measure of the arc PR, m\(\widehat{PR}\) is therefore;

m\(\widehat{PR}\) = 60° + 60° = 120°

Angles and segments are written in order so that they correspond to the congruent angles and segments of the corresponding shape. Example: in question #2, triangle PQR is congruent to triangle STU. This means that P in triangle one corresponds to S in triangle 2. Q corresponds to T and R corresponds to U. This is true for any shape that is congruent.

Explicit formulas are mathematical expressions that represent a function or relationship between variables in a direct and clear way, without the need for further calculations or interpretation.

To find the explicit formulas for the compositions of the given functions, we need to substitute the function inside the other function and simplify:

(a) fog(x) = f(g(x)) = f(5x + 7) = 2(5x + 7) + 3 = 10x + 17

So the explicit formula for fog(x) is 10x + 17.

(b) gof(x) = g(f(x)) = g(2x + 3) = 5(2x + 3) + 7 = 10x + 22

So the explicit formula for gof(x) is 10x + 22.

(c) foh(x) = f(h(x)) = f(x^2 + 1) = 2(x^2 + 1) + 3 = 2x^2 + 5

So the explicit formula for foh(x) is 2x^2 + 5.

(d) hof(x) = h(f(x)) = h(2x + 3) = (2x + 3)^2 + 1 = 4x^2 + 12x + 10

So the explicit formula for hof(x) is 4x^2 + 12x + 10.

The correct statement is B. The center of the circle is the midpoint of the given endpoints of the diameter.

In a circle, the center is located at the midpoint of any diameter. A diameter is a line segment that passes through the center of the circle and has its endpoints on the circle. Therefore, if we are given the endpoints of a diameter, we can determine the center of the circle by finding the midpoint of these endpoints. This means that the x-coordinate of the center will be the average of the x-coordinates of the endpoints, and the y-coordinate of the center will be the average of the y-coordinates of the endpoints.

Option A is not necessarily true because the x-coordinate of the center may or may not be the same as the x-coordinates of the given endpoints.

Option C is incorrect because the center of the circle can be found by determining the midpoint of the diameter.

Option D is not necessarily true because the y-coordinate of the center may or may not be the same as the y-coordinates of the given endpoints.

Therefore, the correct statement is B. The center of the circle is the midpoint of the given endpoints of the diameter.
