Answer: sorry downbad for points god bless

Step-by-step explanation:

The equation x = √-x + 6 cannot have any real solutions, because taking the square root of a negative number is not a real number. So the answer is none of the options listed.

In its most basic form, an equation is a mathematical statement that indicates that two mathematical expressions are equal. 3x + 5 = 14, for example, is an equation in which 3x + 5 and 14 are two expressions separated by a 'equal' sign. A mathematical phrase with two equal sides separated by an equal sign is called an equation. Linear equations are classified into three types: point-slope, standard, and slope-intercept. Identity equations and conditional equations are the two types of equations. An identity holds true for all possible values of the variables. A conditional equation is valid only for certain values of the variables. An equation consists of two expressions joined by an equals sign ("=").

(a) To be eligible for Mensa, an individual's IQ must be in the top 2% of the population. This means that the IQ score must be greater than or equal to the 97th percentile of the normal distribution. We can use the standard normal distribution table to find the 97th percentile.

Since the mean IQ score is 100 and the standard deviation is 15, we can standardize the IQ score to find the z-score:

z = (IQ - mean) / standard deviation

z = (IQ - 100) / 15

The 97th percentile corresponds to a z-score of 2.33. To find the IQ score, we can reverse the standardization formula:

IQ = z x standard deviation + mean

IQ = 2.33 x 15 + 100

IQ = 146.95

So, the lowest Stanford-Binet IQ you could have and still be eligible to join Mensa is 147.

(b) To be eligible for Mensa on the basis of the quantitative reasoning part of the GRE exam, an individual's score must be in the top 2% of the population. This means that the score must be greater than or equal to the 97th percentile of the normal distribution. We can use the standard normal distribution table to find the 97th percentile.

Since the mean score on the quantitative reasoning part of the GRE is 151.3 and the standard deviation is 8.7, we can standardize the score to find the z-score:

z = (score - mean) / standard deviation

z = (score - 151.3) / 8.7

The 97th percentile corresponds to a z-score of 2.33. To find the score, we can reverse the standardization formula:

score = z x standard deviation + mean

score = 2.33 x 8.7 + 151.3

score = 162.291

So, the score required to be eligible for Mensa on the basis of the quantitative reasoning part of the GRE exam is approximately 162. Round to the nearest whole number, the score would be 162.

True, that {~v1, ~v2, ~v3, ~v4}is also a linearly dependent set.

What is a linearly independent set?

A collection of vectors is said to be linearly independent in vector space theory if no nontrivial linear combination of the vectors equals the zero vector. The vectors are considered to be linearly dependent if such a linear combination occurs.

(i.e., all coefficients = 0). A single element set {v} is linearly independent if and only if v ≠ 0.

Now,

As given that

x1v1 + x2v2 + x3v3 = 0 with x1, x2, x3 not all zero, then x1v1 + x2v2 + x3v3 + 0 v4 = 0 and still the coefficients are not ALL zero.

The end behavior of f(x) = -x^4 + x^2 - x + 1 is that it approaches negative infinity as x approaches both positive and negative infinity.

The end behavior of a function refers to the limiting behavior of the function as x approaches positive infinity and negative infinity.

For the function f(x) = -x^4 + x^2 - x + 1, as x approaches positive infinity, the x^4 term dominates, and the value of the function approaches negative infinity.

As x approaches negative infinity, the x^4 term again dominates and the value of the function approaches negative infinity.

Therefore, the end behavior of f(x) = -x^4 + x^2 - x + 1 is that it approaches negative infinity as x approaches both positive and negative infinity.

a) For two distinct real roots: x > 0 or x > m

b) For two distinct real roots: x > 0 or x > 2m

c) For two distinct real roots: x > 0 or x > 4

This is based on the quadratic equation.

Only non-negative integer powers of x are present in the quadratic equation, making it a polynomial equation. In actuality, the Latin word quadratus, which means square, is the root of the term quadratic. The quadratic equation has the generic form ax² + bx + c = 0. where x is an unknowable variable and a, b, and c are mathematical coefficients.

a) Quadratic equation: x² - 4x + m = 0

The discriminant: Δ = b² - 4ac

Δ = (2x)² - 4.x.(m)

Δ = 4x² - 4mx

Δ = 4x (x - m)

For two distinct real roots: Δ > 0

4x (x - m) > 0

x > 0 or x > m

For two real roots: Δ ≥ 0

4x (x - m) ≥ 0

x ≥ 0 or x ≥ m

For a repeated root: Δ = 0

4x (x - m) = 0

x = 0 or x = m

(b) Quadratic equation: mx² + 3x + 2 = 0

The discriminant: Δ = b² - 4ac

Δ = (3x)² - 4.mx.(2)

Δ = 4x² - 8mx

Δ = 4x (x - 2m)

For two distinct real roots: Δ > 0

4x (x - 2m) > 0

x > 0 or x > 2m

For two real roots: Δ ≥ 0

4x (x - 2m) ≥ 0

x ≥ 0 or x ≥ 2m

For a repeated root: Δ = 0

4x (x - 2m) = 0

x = 0 or x = 2m

(c) Quadratic equation: x² - mx + 1 = 0

The discriminant: Δ = b² - 4ac

Δ = (x)² - 4.x.(1)

Δ = x² - 4x

Δ = x (x - 4)

For two distinct real roots: Δ > 0

x (x - 4) > 0

x > 0 or x > 4

For two real roots: Δ ≥ 0

x (x - 4) ≥ 0

x ≥ 0 or x ≥ 4

For a repeated root: Δ = 0

Answer:

177°

Step-by-step explanation:

A sector is the area between two radi.

We are given the perimeter of the sector as 21.4cm and the radius 4.2cm. Subtracting two radi from the perimeter will give us the arc of the sector as 13.

As we know, the formula for the length of an arc is: length of arc = ∅/360 × πd. Diameter is double the radius so in this case it's 8.4; so filling in the blanks our new formula is: 13 = ∅/360 × 8.4π.

We are trying to find ∅ which is the degree of the sector. So from this formula we can rearrange it by dividing 8.4π on both sides of the equation giving ¹³/8.4π = ∅/360; from here we multiply 360 on both sides and therefore getting ∅ on its own therefore allowing us to equate it.

Plug that all into a calculator and you get 177.3440794 so you can round it down to 177°

Rewritten the Expression Using Logical AND Parentheses as "(X > 0) AND (X < 10)"

A logical operator is a symbol or keyword used in a programming language to perform a logical operation on one or more values.

The expression "0 < X < 10" is often misinterpreted as a range for a single variable X.

However, in most programming languages, this expression is considered an error because it does not explicitly state the logical relationship between the two inequalities.

To correct the expression, we use the logical operator AND to connect the two inequalities. The resulting expression, "(X > 0) AND (X < 10)", states that a variable X is within the desired range if it is greater than 0 and less than 10. The parentheses are used to make the expression clearer and to ensure that the logical operation is applied to the correct values.

Hence, "(X > 0) AND (X < 10)"

The pair of transformations that could map ABC to A’B’C’, such that the triangles are similar but not congruent are dilation and rotation

Resizing an item uses a transition called Dilation. Dilation is used to enlarge or contract the items. The result of this transformation is an image with the same shape as the original. However, there is a variation in the shape's size. Dilation transformations ensure that the shape will stay the same and that corresponding angles will be congruent

Given data ,

Let the triangle be represented as ΔABC

Let the dilated triangle be represented as ΔA'B'C'

Let the dilation scale factor be represented as k

Now , when a triangle is dilated by a scale factor of k , there is a change in the shape of the triangle

After a dilation , the triangle will enlarge or compress by a factor k , but it will be similar to the parent triangle

Now , when the triangle is rotated , it only changes the initial coordinates of A , B and C

Let S₁ and S₂ be subsets of a vector space V. So, proves are shown as well.

A vector space, also known as a linear space, is a collection of vectors that have been put together and multiplied ("scaled") by integers known as scalars. Real numbers are frequently seen as being scalars. Scalar multiplication by rational numbers, complex numbers, etc., on the other hand, seldom occurs. The term "subspace" refers to a vector space that is enclosed within another vector space. Each subspace is a vector space in and of itself, but it also has a definition in relation to another (bigger) vector space. We'll soon find out that there are a lot of different subspaces from earlier parts that we already know about.

Let, S₁ and S₂ be subsets of vector space V

Now, S₁ ⊆  V, S₂ ⊆  V

(S₁ ∩ S₂) ⊆ V

Let, x ⊆ span (S₁ ∩ S₂)

x ∈ span (S₁) and x ∈ span (S₂)

x ∈ span (S₁ ∩ S₂)

∴ span (S₁ ∩ S₂) ⊆ span (S₁) ∩ span (S₂)

span (S₁ ∩ S₂) =  span (S₁) ∩ span (S₂)

where either S₁ ⊆ S₂ or, S₂ ⊆ S₁

span (S₁ ∩ S₂) ≠  span (S₁) ∩ span (S₂)

where, (S₁ ⊆ S₂) = ∅ but span (S₁) ∩ span (S₂)

(S₁ ∩ S₂) = ∅ i.e. span (S₁ ∩ S₂)

but span (S₁) = R₁²

span (S₂) = R₁²

Thus, span (S₁) ∩ span (S₂) = R₁²
