The terms empty set, null set, and void set are all used to describe a set that is empty of any elements.
What is meant by empty sets?The empty set is the only set in mathematics that possesses no items; its size or cardinality is 0. While in other theories, its existence can be inferred, some axiomatic set theories guarantee the presence of the empty set by introducing an axiom of empty set.
An empty set is a set that contains no elements and can be represented by the symbol, which indicates that it is empty of elements. It has a definite number of elements since the finite set contains a countable number of items and the empty set has none. An empty set is a finite set since it has a cardinality of zero.
Therefore, the correct answer is option (c) (even prime numbers).

find two vectors in u1 and u2 in r3 so that span u1 u2 = p
Span {u1, u2} = P, and we have found two vectors in u1 = (1, 0, -a/c) and u2 = (0, 1, -b/c) in R3 that span the plane P.
Given: "Find two vectors in u1 and u2 in R3 so that span {u1, u2} = P", where P is a plane in R3.
To find the vectors u1 and u2, we need to find two linearly independent vectors that lie in the plane P.
One possible method to find these vectors is to choose a point on the plane and find a normal vector to the plane. We can then use the point and the normal vector to parameterize the plane.
For example, let's choose a point on the plane as (x0, y0, z0) and a normal vector to the plane as n = (a, b, c).
Then, the equation of the plane can be written as:
ax + by + cz = d
where d = a * x0 + b * y0 + c * z0
We can then choose two linearly independent vectors in the plane by taking partial derivatives with respect to x and y, respectively.
Let's choose u1 = (1, 0, -a/c) and u2 = (0, 1, -b/c). These two vectors lie in the plane and are linearly independent.
Therefore, span {u1, u2} = P, and we have found two vectors in u1 and u2 in R3 that span the plane P.

Is W a subspace of the vector space? If not, state why. (Select all that apply.)
W is the set of all nonnegative functions in C(−[infinity], [infinity]).
W is a subspace of C(−[infinity], [infinity]).W is not a subspace of C(−[infinity], [infinity]) because it is not closed under addition.W is not a subspace of C(−[infinity], [infinity]) because it is not closed under scalar multiplication.
W satisfies both conditions and is closed under addition and scalar multiplication.
What is vector space?In mathematics, a vector space is a fundamental concept in linear algebra.
It is a mathematical structure that consists of a set of objects called vectors, along with operations for vector addition and scalar multiplication.
These operations follow certain axioms, which define the properties of a vector space.
The statement "W is the set of all nonnegative functions in C(−∞, ∞)" does not specify the vector space C(−∞, ∞) correctly.
To determine if W is a subspace of a given vector space, we need to define the vector space correctly.
However, assuming C(−∞, ∞) refers to the set of all continuous functions defined on the interval (−∞, ∞), we can analyze whether W is a subspace of this vector space.
To be a subspace, W must satisfy two conditions:
W must be closed under addition.
W must be closed under scalar multiplication.
Let's evaluate these conditions for W, the set of all nonnegative functions in C(−∞, ∞):
W is closed under addition:
If we take two nonnegative functions from W, their sum will also be nonnegative.
Thus, the sum of any two functions from W will remain in W. Therefore, W is closed under addition.
W is closed under scalar multiplication:
If we multiply a nonnegative function from W by a positive scalar, the result will still be a nonnegative function.
Thus, scalar multiplication by a positive scalar preserves the nonnegativity of the function.
Therefore, W is closed under scalar multiplication.
Based on the above analysis, W satisfies both conditions and is closed under addition and scalar multiplication.

Given,
Volume of a Bird Cage. A company makes rectangular shaped bird cages with height b inches and square bottoms.
Height = b
Volume V = 6³-6b²+9b.
Length of each side (s) :
V = 6³-6b²+9b.
s^2 b = b (b^2 - 6b + 9 )
s^2 = b^2 - 6b + 9
(a - b ) ^2 = a^2 + b^2 -2ab
s^2 = (b-3) ^2
s = b-3
height is 18 inches and height is given as b
Hence, b = 18
s= b-3 (from i)
= 18 - 3
s = 15
Therefore volume:
volume of rectangle = l x b x h
V= 18 x15 x15= 4,050
(If height = 15
then, b = 15
b -15 = 0
Definition of remainder theorem:
we divide a polynomial P(x) by a factor ( x – a); to find a smaller polynomial along with a remainder. The factor doesn't have to be a part of the polynomial.
b^3 - 6b^2 + 9b / b-15 = 2160

This paperweight is a hemisphere with a diameter of 7cm. The glass has a density of 3g/cm squared. Calculate the the mass of the paperweight.
Give your answer to 3 significant figures
WILL MARK BRAINLIEST!
Answer:
The answer assumes that the density of glass is 3 g/cm^3, not 3 g/cm^2.
The mass of the paperweight is 270 grams.
Step-by-step explanation:
Lets calculate the volume of a sphere having a radius of 3.5cm, and then divide that by 2 to get the volume of the hemisphere (half a sphere). The sphere has a diameter of 7cm (therefore, a radius of 3.5cm).
Vol (sphere) = (4/3)πr^3
Vol = (4/3)(3.14)(3.5cm)^3
Vol = 180 cm^3
Half of this (the hemisphere) will be 90 cm^3
We know the volume, and we know the density of glass (3 g/cm^3), so multiply the two to obtain the mass of the paperweight.
(90 cm^3)*(3g/cm^3) = 270 grams
se tienen 10 parlantes idénticos que emiten sonido simultáneamente y el nivel de intensidad medido en un punto es 100 db, ¿cuál es el nivel de intensidad del sonido que emite cada parlante?
The total sound level at the point is 100 dB (10 dB x 10 speakers).
The formula for calculating the sound level emitted by each speaker is 10 * log (100 / 10) = 10 dB. This means that each speaker emits a sound level of 10 dB.
To calculate this, we first need to understand the principle of the logarithmic addition of sound levels. The logarithmic addition of sound levels states that when two sound waves with different amplitudes overlap, the resulting amplitude is the sum of the logarithms of the individual amplitudes.
For example, let's say we have two sound waves with amplitudes of 10 dB and 20 dB. The resulting amplitude will be 10 * log (10 + 20) = 10 * log (30) = 10 dB + 20 dB = 30 dB.
Therefore, in our example, the 10 speakers each emit a sound level of 10 dB. This means that when all 10 speakers play simultaneously, the total sound level at the point is 100 dB (10 dB x 10 speakers).

x is less than or equal to 8, y is more than -3. Graph the solution of the system of linear inequalities. (and fill in)
Answer:
The solution to the system of linear inequalities x <= 8 and y > -3, represented on a coordinate plane, is a region that satisfies both inequalities. It is the half-plane formed by the line x=8 and above the line y=-3 .
Step-by-step explanation:
The solution to the system of linear inequalities x <= 8 and y > -3 can be represented on a coordinate plane as a region that satisfies both inequalities.
To graph the solution, we first plot the line x = 8 on the coordinate plane. Since x <= 8, this line represents the boundary of the solution. Everything to the left of the line x = 8 is included in the solution.
Next, we plot the line y = -3. Since y > -3, everything above the line y = -3 is included in the solution.
The final graph will be a half-plane formed by the line x=8 and above the line y=-3 .

The cost to produce bottled spring water is given by C(x) = 16x – 63 where x is the number of thousands of bottles. The total income (revenue) from the sale of these bottles is given by
C(x) = 16x – 63, where x is the number of thousands of bottles, gives the cost of producing bottled spring water.
The formula R(x) = - x2 + 326x – 7463 calculates the total amount (revenue) from the sale of these bottles.
How to determine?Bottles sold will yield the highest profit.
Profit maximization
Profit after selling 245 thousand bottles
C(x) = 16x – 63
R(x) = – x² + 326x – 7463.
Revenue – Cost = Profit
P(x) = R(x) – C (x)
= – x² + 326x – 7463 – (16x – 63) (16x – 63)
= – x² + 310x – 7400
Choice c)
Profit = x2 minus 310x minus 7400
P(x) = – x² + 310x – 7400
P’(x) = -2x + 310
P’(x) = 0 => -2x + 310 = 0 => x = 155
P’’(x) = - 2 < 0
As a result, profit is greatest at x = 155.
The highest profit will be generated if 155 bottles are sold.
Alternative b)
Profit maximization at x = 155
P(x) = – x² + 310x – 7400

c. The percentage of GMAT scores between 447 and 547 is approximately 84.1%.
d. The percentage of GMAT scores between 347 and 647 (to 1 decimal) is approximately 98.0%.
a. The GMAT score of 647 is 100 points above the average score of 547. Using the standard deviation of 100, we can calculate the standard score (z-score) as 647-547/100 = 1.
Using a standard normal table, we can find that the percentage of GMAT scores that are 647 or higher is approximately 15.9%.
b. The GMAT score of 747 is 200 points above the average score of 547. Using the standard deviation of 100, we can calculate the standard score (z-score) as 747-547/100 = 2.
Using a standard normal table, we can find that the percentage of GMAT scores that are 747 or higher is approximately 2.3%.
c. The GMAT scores between 447 and 547 are 100 points below and 100 points above the average score of 547, respectively.
Using the standard deviation of 100, we can calculate the standard score (z-score) as (447-547)/100 = -1 and (547-547)/100 = 0.
Using a standard normal table, we can find that the percentage of GMAT scores that are between -1 and 0 is approximately 84.1%.
d. The GMAT scores between 347 and 647 are 200 points below and 100 points above the average score of 547, respectively.
