How do u know somthing is a proportional relationship
Answer: You can tell if a table shows a proportional relationship by calculating the ratio of each pair of values. If those ratios are, all the same, the table shows a proportional relationship.
2. Let S = R - {0}, with the wacky definitions of vector addition and scalar multiplication given below.
Verify or disprove that S is a Vector Space.
For x, y in S, the definition:
Vector Addition: x + y = xy
• Scalar Multiplication: c*x = x^C.
(ie. 2+5= 2*5 = 10)
Hint: First identify the additive identity
A vector space, also known as a linear space, is a set whose elements, frequently termed vectors, can be added to and multiplied ("scaled") by figures known as scalars. Real numbers make up scalars most of the time, but they can also be complex numbers or, more broadly, components of any field.
Varied SpacesEvery vector space has a scalar field F at its foundation (to be specified shortly).
Real and complex numbers are two examples of scalar fields.
Real numbers R:
C: Complex numbers.
We only utilize these fields in this context.
Definition : A group of objects in a vector space V have a (vector)
scalar multiplication defined as closed under both addition and multiplication
also satisfying the following axioms:
I For any x V and, F, ( + )x = x + x
(ii) α(βx)=(αβ)x
(iii) For all x, y V, x + y = y + x
(iv) For any x, y, and z > V, x + (y + z)=(x + y) + z.
(v) α(x + y) = αx + αy
(vi) O V z 0 + x = x, where 0 is commonly referred to as the origin
Since V cannot be left using vector addition or scalar multiplication, the "closed" criterion described above states that for any, F and x, y V x + y V. Additionally, the "+" is in the field when we write for, F and x V ( + )x, but it is in the vector space when we write for x + y for x, y V. This symbol has a variety of uses.
Examples.(1) R2 is equal to the two-dimensional space (a1, a2) | a1, a2 R.
(2) In an n-dimensional space, Rn = (a1, a2,..., an) | a1, a2,..., an.
An "n-tuple" is (a1, a2,...,an).
(3) C, the field of complex numbers, to C2 and Cn, respectively, to R2 and Rn.
Pn = l n j = 0 ajxj | a0,
The polynomial space of all polynomials of degree n is denoted as Pn = l n j=0 ajxj | a0, a1,...,an R M. Be aware that this covers polynomials of all degrees, not only those with n degrees exactly.
(5) fp = (ai,...) | ai p, |ai| R. Vectors in the form of infinite-tuples of numbers make up this space. To properly designate the field, we would write fp(R) or fp(C).
Trigonometric polynomials TN = F N n=1 a sin nx | a1,...,an R k are included in the list.
Typical vecs in Rn e1 = (1, 0,... , 0)
e2 = (0, 1, 0,... , 0) (0, 1, 0,... , 0)

A bank account gathers compound interest at a
rate of 5% each year.
Another bank account gathers the same amount of
money in interest by the end of each year, but
gathers compound interest each month.
If Cameron puts £4200 into the account which
gathers interest each month, how much money
would be in his account after 2 years and
7 months?
Give your answer in pounds to the nearest 1p.
Based on the compound interest rate on the bank account and the number of months that Cameron invested the amount for, the money in his account will be £4,777.81
What amount will be in the account?The amount that will be in the account after 2 years and 7 months can be found by the formula:
= Amount invested x ( 1 + periodic rate) ^ number of periods
The number of months (periods) is:
= 2 years + 7 months
= 31 months
The periodic rate is:
= 5% / 12 months a year
= 5/12%
The amount that Cameron will have in his bank account after 2 years and 7 months will be:

Find the sum. 2 3/6 + 4 1/6
Answer:
6 4/6
Explanation:
To sum 2 3/6 and 4 1/6, we first need to convert the mixed numbers to fractions as follows
[tex]\begin{gathered} 2\frac{3}{6}=\frac{(2\times6)+3}{6}=\frac{12+3}{6}=\frac{15}{6} \\ 4\frac{1}{6}=\frac{(4\times6)+1}{6}=\frac{24+1}{6}=\frac{25}{6} \end{gathered}[/tex]Now, we can add the numbers as
[tex]\frac{15}{6}+\frac{25}{6}=\frac{15+25}{6}=\frac{40}{6}[/tex]Finally, when we divide 40 by 6, we get 6 as a quotient and 4 as a remainder, so 40/6 is equivalent to
[tex]6\frac{4}{6}[/tex]Therefore, the answer is 6 4/6
A system of inequalities is shown.Which system is represented in the graph? y > –x2 – x + 1y < 2x2 + 3 y ≤ x2 – x + 1y < 2x2 + 3 y ≥ x2 – x + 1y ≤ 2x2 + 3 y ≥ –x2 – x + 1y > 2x2 + 3
The system of inequatilies that is represented in the graph is:
y ≥ –x² – x + 1
y > 2x² + 3
We can confirm this statement since the first equation implies that the system doesn't include any point bellow the parabola y = -x² - x + 1, and the second equation implies that the system must include only points above the parabola y = 2x² + 3
On a piece of paper, graph y ≥ 2x – 3. Then determine which answer choice matches the graph you drew.

(a) Give an example of an angle which is coterminal with 260°.
(b) State the reference angle associated with 260°.
(b) Convert 260° to radians. Leave the answer in terms of
π .
a) 620° is an angle coterminal to 360°. The reference angle associated with 260° is 260°.
b) The measure of 260° in radian system equals to 13π / 9 radians.
How to analyze coterminal angles
Two angles are coterminal when they share the same initial and terminal sides. Two consecutive coterminal angles have a difference of 360° (2π radians). Then, we can find any angle of a family of coterminal angles by using this formula:
θ' = θ + i · 360°
Where:
θ - Reference angle, in degrees.i - Angle index.a) If we know that θ = 260° and i = 1, then the measure of an example of coterminal angle is:
θ' = 260° + 1 · 360°
θ' = 620°
620° is an angle coterminal to 360°.
The reference angle is the angle whose measure is equal to or greater than 0° and equal to or less than 360°. Thus, the reference angle associated with 260° is 260°.
b) According to radian system, 2π radians are equal to 360°. Thus, the measure of 260° is found by the following simple rule of three:
x = 260° × 2π / 360°
x = 13π / 9 rad
The measure of 260° in radian system equals to 13π / 9 radians.

What is a proportion?A proportion can be defined as an equation which is typically used to represent (indicate) the equality of two (2) ratios. This ultimately implies that, proportions can be used to establish that two (2) ratios are equivalent and solve for all unknown quantities.
Mathematically, a direct proportion can be represented by the following equation:
y = kx
Where:
y and x are the variables.k represents the constant of proportionality.Next, we would determine the numerical value of the constant of proportionality (k) as follows:
y = kx
k = y/x
k = 0.6/2
k = 0.3
When y = 1.5, the value of x is given by:
x = y/k
x = 1.5/0.3
x = 5.
When y = 2.4, the value of x is given by:
x = y/k
x = 2.4/0.3
x = 8.
In conclusion, the values of x are 5 and 8 while the value of y is 2.4.

The required probability would be 0.146 that it takes 3 shots for the marksman to hit the long-range target.
What is probability?The probability is defined as the possibility of an event being equal to the ratio of the number of favorable outcomes and the total number of outcomes.
A marksman has a probability of 0.322 for hitting a certain long-range target which is given in the question.
It takes the marksman 3 shots to hit the long-range target = P(E)
Required probability = P(E)
Here no long-range hits in the 1st two shots = (E₁)
And a long-range hit on the 3rd shot = (E₂)
P(E) = P( (E₁) and (E₂))
P(E) = (1 - 0.288) (1-0.288)(0.288)
P(E) = 0.146

252 + 210 + 120 + 45 + 10 + 1 = 638 ways.
In item b, each must have at least three toppings, hence the number of ways for each is:
120 + 210 + 252 + 210 + 120 + 45 + 10 + 1 = 968 ways.
968 ways for each, two people, hence, by the Fundamental Counting Theorem, the number of ways is:
968² = 937,024 ways.
In item c, the number of ways is the sum of all the possible toppings, except zero, from the conditions given, hence:

[tex]\begin{gathered} \frac{1}{4}AB=\frac{1}{4}\sqrt[]{(x_2-x_1)^2+(y_2}-y_1)^2 \\ \frac{1}{4}AB=\frac{1}{4}\sqrt[]{(14-2)^2+(9-5)^2} \\ \frac{1}{4}AB=\frac{1}{4}\sqrt[]{12^2+4^2}\text{ = }\frac{1}{4}\sqrt[]{144+16} \\ \frac{1}{4}AB=\frac{1}{4}\text{ }\sqrt[]{160}=\frac{1}{4}\times12.649=3.162 \end{gathered}[/tex]
