Step-by-step explanation:

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

Square ABCD has vertices at A(−2,1), B(2,7), C(8,3), and D(4,−3). How many units is the perimeter of square ABCD?

The factored form makes it easiest to see the zeros of the function, as they correspond to the roots (x-intercepts) of the equation. In this form, the zeros are x=4 and x=6.

        (x-4) = 0 or (x-6) = 0

        x = 4 or x = 6

These values correspond to the x-intercepts, or zeros, of the function.

The zeros of a function are the values of x where the function intersects the x-axis, or where the value of the function is equal to zero. In a factored form, each factor is equal to zero at specific values of x. These values correspond to the x-intercepts of the function, which are the zeros.

By setting each factor equal to zero and solving for x, we find the x-intercepts of the function, which are the zeros. This is why the factored form makes it easiest to see the zeros of a function.

Limit, (4 + b)² - 8², Algebraically Determining Limits, h approaches 0, Expansion Formula for Square, Lim [(4 + b + h)² - 8² = (4 + b)² - 64.

To algebraically determine the limit, we can use the definition of a limit.

The limit of (4 + b)²-8² as h approaches 0 is equal to the limit of (4 + b + h)² - 8² as h approaches 0 minus (4 + b)² - 8².

Using the expansion formula for a square, we can write:

(4 + b + h)² - 8² = (4 + b)² + 2(4 + b)h + h² - 64

Now, taking the limit as h approaches 0:

lim [(4 + b + h)² - 8²] = lim [ (4 + b)² + 2(4 + b)h + h² - 64 ] = (4 + b)² - 64

So,

lim (4 + b)² - 8² as h approaches 0 = lim [(4 + b + h)² - 8²] - (4 + b)² + 64 = lim [(4 + b + h)² - 8²]

Hence,

lim (4 + b)² - 8² as h approaches 0 = lim [(4 + b + h)² - 8² = (4 + b)² - 64.

The function f is increasing for x > 3/2.

To determine the values of x for which the function f is increasing, we need to find the critical points of f, which are the values of x where the function changes from increasing to decreasing or vice versa.

The first step is to find the derivative of f:

f'(x) = (2x - 3)e-x

Next, we need to find the critical points by setting f'(x) = 0 and solving for x:

(2x - 3)e-x = 0

2x - 3 = 0

x = 3/2

This is the only critical point of f. To determine the behavior of f near this critical point, we need to find the second derivative of f:

f''(x) = (2 - 3e-x)

For x < 3/2, f''(x) < 0, which means f is concave down and f'(x) is decreasing. This means that f is decreasing for x < 3/2.

For x > 3/2, f''(x) > 0, which means f is concave up and f'(x) is increasing. This means that f is increasing for x > 3/2.

Step-by-step explanation:

The volumes of the cylinder, the cone and the hemisphere are 512π cm³, 170.6π cm³ and 341.3π cm³ respectively.

Volume is defined as the space occupied within the boundaries of an object in three-dimensional space.

Given that, a hemisphere fits snugly inside a cylinder with a radius of 8 cm. A cone fits snugly inside the same hemisphere.

Since, all of them are tightly packed in one another therefore, radius of all them will be equal,

And, and the radius of the cylinder is 6 cm, the radius of the hemisphere equals the radius of the cylinder. Also, the height of the cylinder equals the radius of the hemisphere.

r = radius of cylinder = 8 cm and

h = height of cylinder = radius of hemisphere = 8 cm

We know that,

Volume of a cylinder = π × radius² × height

Volume of a cone = 1/3 × π × radius² × height

Therefore,

a) The volume of cylinder =

π × 8² × 8 = 512π cm³  

b) The volume of cone =

1/3 × π × 8² × 8 = 170.6π cm³  

c) Volume of the hemisphere = (512π + 170.6π) / 2

= 341.3π cm³  

Hence, the volumes of the cylinder, the cone and the hemisphere are 512π cm³, 170.6π cm³ and 341.3π cm³ respectively.

Given the information in the problem, we can use the Pythagorean theorem to find the length of the other leg, a:

      [tex]c^2 = a^2 + b^2\\\\7.5^2 = a^2 + 5.4^2\\\\56.25 = a^2 + 29.16\\\\56.25 - 29.16 = a^2\\\\27.09 = a^2\\\\a = \sqrt{27.09} \\\\a = 5.2\ yards[/tex]

A vector is a mathematical object that can be added and multiplied by a number, also known as a scalar.

In this case, we have two vector spaces, V and W, which are sets of vectors that can be added and scaled in a certain way, with the scalars taken from a field F.

=> (v1, w1)+(v2, w2)=(v1 + v2, w1 + w2)

We then define a new set, Z, which consists of ordered pairs of vectors, one from V and one from W. With the operations of adding two vectors element-wise and scaling a vector by a scalar, we can show that Z is also a vector space over F.

=> c(v1, w1)=(cv1, cw1).
