Z is a vector space over F with the operations(v1, w1)+(v2, w2)=(v1 + v2, w1 + w2) and c(v1, w1)=(cv1, cw1) is proved.
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).
To do this, we need to verify that Z satisfies the properties of a vector space, such as closure under addition and scalar multiplication, associativity and commutativity of addition, the existence of an additive identity and inverse, and distributivity of scalar multiplication over vector addition.

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]

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

When considering stand-alone risk, the return distribution of a less risky investment is more placed ("tighter") than that of a riskier investment. What shape would the return distribution have for an investment witha) completely certain returns andb) completely uncertain returns?
For an investment with completely certain returns, the return distribution would be a very tight, vertical line at the predetermined return. This is because the risk associated with the investment is zero, meaning the return will not vary regardless of market conditions.
For an investment with completely uncertain returns, the return distribution would be a flat line with no particular shape. This is because the risk associated with the investment is very high, meaning the return could be anything, as it is impossible to predict the returns with any degree of accuracy.

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.
What is volume?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.

What are all values of x for which the function f defined by f(x) = (x2 - 3)e-x is increasing?.
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.
