The perimeter of square ABCD is 8 [tex]\sqrt{13}[/tex] units.
Coordinates of the vertices are A(-2, 1), B(2, 7), C(8, 3) and D(4, -3)
A square's perimeter is equal to the sum of its four sides or the product of four and one of its sides.
Therefore, the square's perimeter is equal to a + b + c + d.
4 × any of the sides because the sides of a square are equal to one another.
Since ABCD is a square:
Perimeter of a square = 4 × (length of a side)
=4 × AB
Formula to calculate the distance between two points [tex]$\left(x_1, y_1\right)$[/tex] and [tex]$\left(x_2, y_2\right)$[/tex] is, [tex]$\mathrm{d}=\sqrt{\left(x_2-x_1\right)^2+\left(y_2-y_1\right)^2}$[/tex]
Therefore, distance between two points A(-2, 1) and B(2, 7) will be,
AB = [tex]\sqrt{(2+2)^2+(7-1)^2} \\[/tex]
AB = [tex]\sqrt{4^2+6^2} \\[/tex]
AB = [tex]\sqrt{52} \\[/tex]
AB = 2[tex]\sqrt{13}[/tex]
Hence the perimeter of square ABCD can be calculated as 4 × AB
Now Perimeter of a square ABCD = 4 × 2[tex]\sqrt{13}[/tex]
= 8 [tex]\sqrt{13}[/tex] units
Therefore the answer is 8 [tex]\sqrt{13}[/tex] units

a piece of paper is to display 128 128 space, 128, space square inches of text. if there are to be one-inch margins on both sides and two-inch margins at the bottom and top, what are the dimensions of the smallest piece of paper (by area) that can be used?
The dimensions of the smallest piece that can be used are: 10 by 20 and the area is 200 square inches.
The area of a square with sides of one inch is equal to one square inch (plural: square inches).
We have that:
Let the dimension of the paper be x and y.
Such that:
Length = [tex]x[/tex]
Width = [tex]y[/tex]
So:
Area = [tex]x*y[/tex]
Substitute 128 for Area
[tex]128=x*y[/tex]
Make x the subject.
[tex]x=\frac{128}{y}[/tex]
When 1 inch margin is at top and bottom
The Length becomes:
[tex]Length =x+1+1[/tex]
[tex]Length = x+2[/tex]
When 2-inch margin is at both sides
The width becomes:
[tex]Width = y+2+2[/tex]
[tex]Width = y+4[/tex]
The New Area (A) is then calculated as:
[tex]A = (x+2)*(y+4)[/tex]
Substitute [tex]\frac{128}{y}[/tex] for x
[tex]A = (\frac{128}{y}+2 )*(y+4)[/tex]
Open Brackets
[tex]A = 128 + \frac{512}{y} + 2y + 8[/tex]

[tex]A = \frac{512}{y} + 2y + 8+128[/tex]
[tex]A = \frac{512}{y} +2y+136[/tex]
[tex]A = 512y^{-1} +2y + 136[/tex]
To calculate the smallest possible value of y, we have to apply calculus.
Differentiate A with respect to y
[tex]A' = -512y^{-2}+2[/tex]
Set
[tex]A' = 0[/tex]
This gives:
[tex]0=-512y^{-2}+2[/tex]

[tex]512y^{-2} = 2[/tex]
Multiply through by [tex]y^{2}[/tex]
[tex]y^{2} *512y^{-2} = 2*y^{2}[/tex]
[tex]512 = 2y^{2}[/tex]
Divide through by 2.
[tex]256 = y^{2}[/tex]
Take square roots of both sides.
[tex]\sqrt{256= y^{2} }[/tex]
[tex]16 =y\\\\y=16[/tex]
Recall that:
[tex]x = \frac{128}{y}[/tex]
[tex]x = \frac{128}{16}[/tex]
[tex]x=8[/tex]
Recall that the new dimensions are:

The above value is:
[tex]A'' = \frac{1024}{y^{3} } > 0[/tex]

Using the Pythagorean theorem, you can easily calculate the length of BC.
So:
BC = sqrt(12^2 - 6^2) = sqrt(144 - 36) = sqrt(108) = 10.39230485
Now consider triangle BCD. You know all three angles and one side. Using the law of sines you know that ratio of the sine of each angle over the opposite side is constant. So:
BC/sin(55) = CD/sin(90)
BC/sin(55) = CD/sin(90)
sin(90)BC/sin(55) = CD
1*BC/sin(55) = CD
BC/sin(55) = CD

The process takes approximately 14 iterations to reach the desired accuracy.
The Bisection Method will take approximately 14 iterations to find the approximate root of the equation within an error tolerance of 0.001. The mathematics calculations involve finding the midpoint of a given interval [a, b] and then determining whether the midpoint is a root of the equation. If it is not a root, then the interval is divided into two halves, and the process is repeated on the subinterval where the sign of the function changes. This process is repeated until the midpoint is within the desired error tolerance.
To calculate the number of iterations required, we begin by noting that the initial interval used is [1, 0]. The midpoint of this interval is 0.5. This value is then plugged into the function to determine if it is a root. Since it is not, the interval is then divided into two halves and the process is repeated. This process is repeated until the midpoint is within the desired error tolerance of 0.001. In this case, it takes approximately 14 iterations to reach the desired accuracy.

find the intervals on which the given function is increasing and the intervals on which it is decreasing. (enter your answers using interval notation.)h(x) = (x 4)2 3x − 7
The intervals can be written as (-∞, 4) and (4, ∞) for increasing, and [4, 4] for decreasing.
The function h(x) = (x - 4)² - 3x + 7 is a parabolic function that opens upwards.
The function has a critical point at x = 4, where it changes direction from decreasing to increasing.
To determine the intervals on which the function is increasing or decreasing, we need to look at the sign of the first derivative of the function, which will tell us if the function is increasing or decreasing at any given x value.
In this case, the derivative of
=> h(x) = 2(x - 4) - 3.
Setting this equal to zero and solving for x, we find that x = 4 is the only critical point.
The second derivative of h(x) is 2, which is positive.
This tells us that the first derivative is increasing, which means the original function is increasing.
Therefore, the intervals on which the function is increasing are all x values greater than 4 or all x values less than 4. The intervals on which the function is decreasing are all x values between 4 and 4.

how many numbers are there in all from 4000 to 4999 (both 4000 and 4999 included) having at least one of their digits repeated?
2084 is the total number of integers between 4000 and 4999 with at least one repeated digit.
An integer is a whole number, which can be positive, negative, or zero. A repeated digit refers to a digit that appears more than once in the number.
First, let's count the number of integers between 4000 and 4999 that have no repeated digits. We have 4 choices for the thousands place, as it must be 4. For each of the remaining three places, we have 9 choices for digits (0 to 9, except for 4 in the thousands place). So, the total number of integers between 4000 and 4999 with no repeated digits is 4 * 9 * 9 * 9 = 2916.
Next, we need to count the number of integers with one repeated digit. For this, we need to consider two cases:
When the repeated digit is in the thousands place. In this case, there are only 9 choices for the other three digits, as they cannot be 4. The total number of integers in this case is 9 * 9 * 9 = 729.
When the repeated digit is not in the thousands place. In this case, there are 9 choices for the repeated digit and 8 choices for the other two digits. So, the total number of integers in this case is 9 * 9 * 8 = 648.
Adding the total number of integers in both cases, we get 729 + 648 = 1377 integers between 4000 and 4999 with at least one repeated digit.
Finally, subtracting the number of integers with no repeated digits from the total number of integers between 4000 and 4999, we get 5000 - 2916 = 2084. This is the total number of integers between 4000 and 4999 with at least one repeated digit.

For a recent eion, there were 14 more Democrat than Republican in the tate enate. Thi reulted in a ratio of 6 Democrat to 5 Republican. How many enator were Democrat and how many were Republican?
There were 70 Republicans and 84 Democrats in the state senate.
Let x be the number of Republicans in the state senate.
Then the number of Democrats is x + 14.
We know the ratio of Democrats to Republicans is 6 to 5.
According to the given conditions, we can write the equation as follows -
x / (x + 14) = 5 / 6
Cross multiplying, we get,
6x = 5x + 70
Subtracting 5x from both sides of the equation, we get,
x = 70
Therefore, we get that there were 70 Republicans and 84 Democrats in the state senate.

a bathroom tile pattern has blue, red and white tiles in the ratio 3 : 4 : 8 there are 300 tiles . how many tiles are there of each colour
There are 60 blue tiles, 80 red tiles, and 160 white tiles in the bathroom pattern
How to determine the tiles in each colourLet's call the number of individual tiles "x".
Using the given ratio, we have
Then there are 3x blue tiles, 4x red tiles and 8x white tiles.
The total number of tiles is:
3x + 4x + 8x = 300
Evaluate the like terms
15x = 300
Dividing both sides by 15
x = 300 / 15 = 20
So, we have
Blue = 3 * 20 = 60
Red - 4 * 20 = 80
White = 8 * 20 = 160
So there are 60 blue tiles, 80 red tiles, and 160 white tiles.
