The total perimeter will be 4x^+17 and length be 22.76 cm

As per the data given in the questions,

We have, the shape of the sandwich be rectangular.

We know that, perimeter of the rectangle can be determined by using formula: 2(l+b),

where, l = length of the rectangle

and, b = breadth of the rectangle

The expression for the perimeter of the sandwich would be:

2 (2x^2 + 9) + 2 (2x^2 + 8)

= 4x^2 + 26

Now for finding the length of the crust,

we will put the value of x=1.2,

So, the value of the approximate length of the crust would be:

=4x^2 + 26

= 4 * 1.2^2 + 26

= 22.76 centimetres.

The square root of 9 is 78 less than 9 squared

The square root of 9 is calculated as

                     √9 = √(+ 3)² or√(- 3)²

                           = + 3 or - 3

Let's calculate the square of 9:

                      9² = 81

We need to calculate here, how much the square root of 9 is less than the square of 9 or we can say the difference between the square of 9 and the square root of 9. So, let's say that difference is denoted by d

                                 d = 9² - √9

When √9 = +3

                                 d = 81 - 3

                                 d = 78

When √9 = -3

                                 d = 81 - (-3)

                                 d = 81 + 3

                                 d = 84

Hence, the value of the difference between the square of 9 and the square root of 9 is 78 or 84.

The four-sided geometric object known as a tetrahedron (WXYZ) has four triangle faces that are joined to one another at their edges. Its vertices are all linked, and its faces are all equilateral triangles.

The three-dimensional geometric structure known as a tetrahedron (WXYZ) has four triangle-shaped faces. The edges of each of the tetrahedron's faces are joined to one another. All of the faces are triangular shapes with equal sides, or equilateral triangles. The tetrahedron is a solid shape because all of its vertices are joined together. The tetrahedron's four vertices are joined to one another, forming a pyramid-like shape. The tetrahedron's four vertices are the only points that do not form the triangle faces. The tetrahedron's four faces come together to produce a point in the middle of the shape. The apex of the tetrahedron is where this point is located. The faces of the tetrahedron are all congruent, or identical, as they are a regular polyhedron.

The solution to the given differential equation is a 3-dimensional vector function which satisfies the given initial conditions. The vector function consists of three components, one for each dimension in the equation.

The given differential equation is a 3-dimensional vector equation, of the form ()=⟨12−12,2−1,1⟩. The initial conditions are (1)=⟨0,0,12⟩ and ′(1)=⟨8,0,0⟩. The solution to this equation is a 3-dimensional vector function, ()=⟨, ,⟩. The first component of the vector function is a function of the independent variable, and must satisfy the initial condition (1)=⟨0,0,12⟩. This means that the first component of the vector function must be equal to 0 at x=1. The second component must satisfy the initial condition ′(1)=⟨8,0,0⟩. This means that the second component of the vector function must be equal to 8 at x=1. The third component of the vector function must also satisfy the initial condition (1)=⟨0,0,12⟩. This means that the third component of the vector function must be equal to 12 at x=1. Once the initial conditions have been satisfied, the  equation can be solved to find the vector function.

a) The enlargement needed to be done is 25%.

b) The succession time should be at least t=9 to get a final copy that is less than 15% of the original size.

To determine the quantity or percentage of something in terms of 100, use the percentage formula. Per cent simply means one in a hundred. Using the percentage formula, a number between 0 and 1 can be expressed. A number that is expressed as a fraction of 100 is what it is. It is mostly used to compare and determine ratios and is represented by the symbol %.

Given:

Let the size of the page be q, when it is reduced to 80%, its size becomes

= 80% x q

= 0.80(q)

= 0.80q

When you want to return it into its original size q,

x(0.80q) = q

x = q / 0.80q

x = 1.25

x= 125%

Hence, the enlargement needed to be done is 25%.

b) The size of the page after t number of copying done is given by

C(t) = [tex]C_0(0.80)^t[/tex]

So, C(t) / [tex]C_0[/tex] = [tex](0.80)^t[/tex]

0.15 ≤  [tex](0.80)^t[/tex]

Taking log on both side

log (0.15) ≤ log [tex](0.80)^t[/tex]

log (0.15) ≤ t log (0.80)

log (0.15) /log (0.80)  ≤ t

The concentration of solution A after dilution by a factor of 10 would be 0.0300 M.

The dilution factor is defined as the ratio of the final volume to the initial volume of the solution.

If a solution is diluted by a factor of 10, it means that the final volume of the solution is ten times greater than the initial volume. As a result, the concentration of the solute in the final solution will decrease by a factor of 10.

Therefore, if the initial concentration of the stock solution is 0.300 M, then the concentration after dilution by a factor of 10 of solution A would be

The given equation about an arithmetic sequence is

[tex]a_{n}[/tex] = [tex]a_{1}[/tex] + (n-1) d ; n > 1

Boole's inequality(or the union bound) states that for any at most countable collection of events, the probability that at least one of the events happens is no greater than the sum of the probabilities of the events in the collection.

The objective is to prove the statement using principle of mathematical induction.

The principle of mathematical induction statement that a statement [tex]p_{n}[/tex] about positive integer n, is true if satisfies the following two conditions:

[tex]p_{1}[/tex] is true

If [tex]p_{k}[/tex] is true, then [tex]p_{k+1}[/tex] is true

Consider the statement for n > 1

[tex]p_{n}[/tex] : [tex]a_{n}[/tex] = [tex]a_{1}[/tex] + (n-1) d

Here, it is known that [tex]a_{n}[/tex] is an arithmetic sequence with [tex]a_{1}[/tex] as first term and 'd' as common difference.

Recall that in any arithmetic sequence, each term is determined by adding 'd' to previous term.

Hence, the second term is determined by adding 'd' to first term.

[tex]a_{2}[/tex] = [tex]a_{1}[/tex] + d

For [tex]p_{2}[/tex] , substitute n = 2 in the given statement to verify it for first positive integer.

[tex]p_{n}[/tex] : [tex]a_{n}[/tex] = [tex]a_{1}[/tex] + (n-1) d

[tex]p_{2}[/tex] : [tex]a_{2}[/tex] = [tex]a_{1}[/tex] + (2-1) d

[tex]p_{2}[/tex] : [tex]a_{1} +d[/tex] =   [tex]a_{1} +d[/tex]

The equation in slope intercept form is : [tex]y = \frac{1}{8} x - 223.05[/tex]

The slope intercept form is a process used to determine the equation of a straight line in the coordinate plane. It can be used to determine the equation of a line when given the slope of the straight line and the y-intercept

The slope-intercept form of a line is:

y = mx+b

where m is the slope of the line and b is an intercept of the y-axis.

[tex]m = \frac{y_{2} - y_{1} }{x_{2} - x_{1} }[/tex]

[tex]m = \frac{26.7 - 23.2 }{1998- 1970}[/tex]

[tex]m = \frac{1}{8}[/tex]

So,

[tex]y = \frac{1}{8} x + b[/tex]

To find b we get the point (1970, 23.2) and introduce it in the previous equation.

[tex]23.2= \frac{1}{8} (1970)+ b[/tex]

⇒ 23.2 - 246.25 = b

The distance from point P = (1, -1) to the line through points A = (-2, 2) and B = (0, -4) is 2.23.

What is distance ?

Distance is a numerical or occasionally qualitative measurement of how far apart objects or points are. In physics or everyday usage, distance may refer to a physical length or an estimation based on other criteria.

The slope of the line can be found using the coordinates of points A and B:

m = (y2 - y1) / (x2 - x1) = (-4 - 2) / (0 - (-2)) = -3

Next, we can use the coordinates of point A to find the y-intercept:

b = y - mx = 2 - (-3)(-2) = 2 + 6 = 8

m_perpendicular = -1 / -3 = 1/3

Using the coordinates of point P, we can find the equation of the perpendicular line:

y = m_perpendicular x + b_perpendicular

y = 1/3 x - 1/3

Setting the y-coordinates equal, we can find the x-coordinate of the intersection point:

-3x + 8 = 1/3 x - 1/3

-9x + 24 = x - 1/3

-10x + 24.33 = x

x = 24.33 + 10x

11x = 25.66

x = 2.33

Finally, we can find the y-coordinate of the intersection point using the equation of the perpendicular line:

y = 1/3 x - 1/3

y = 1/3 (2.33) - 1/3 = 0.77

The intersection point is (2.33, 0.77), and the distance from point P to the line is the distance between the two points:

distance = sqrt((x2 - x1)^2 + (y2 - y1)^2) = sqrt((2.33 - 1)^2 + (0.77 + 1)^2) = sqrt(1.33^2 + 1.77^2) = sqrt(1.7769 + 3.1369) = sqrt(4.9138) = 2.23.

So, the distance from points P = (1, -1) to the line through points A = (-2, 2) and B = (0, -4) is 2.23.
