Step-by-step explanation: Its simple math its just either x2 or what's it divided off

a)T(u) + T(v) T is a linear transformation

b)[3 -2 ; 2 0]

c)T is one-to-one.

a) To prove that T is a linear transformation, we need to show that it satisfies two conditions.

1. Additivity: T(u + v) = T(u) + T(v)
Let u = [u1, u2] and v = [v1, v2], then
T(u + v) = T([u1 + v1, u2 + v2]) = [3(u1 + v1) - 2(u2 + v2), 2(u2 + v2)]
= [3u1 - 2u2 + 3v1 - 2v2, 2u2 + 2v2]
= [3u1 - 2u2, 2u2] + [3v1 - 2v2, 2v2]
= T(u) + T(v)

2. Homogeneity: T(cu) = cT(u)
Let u = [u1, u2] and c be any scalar, then
T(cu) = T([cu1, cu2]) = [3cu1 - 2cu2, 2cu2] = c[3u1 - 2u2, 2u2]
= cT(u)

Therefore, T satisfies both conditions, and is a linear transformation.

b) The standard matrix of T is the matrix A = [3 -2 ; 2 0]

c) To determine whether T is one-to-one, we look at the matrix A. Since the matrix A has a non-zero determinant, which is equal to -4, then T is one-to-one.

The two linear functions that have a minimum value but no maximum value are:

f(x) = 10 - 3x over the domain x ≤ 9

f(x) = 5x - 1 over the domain x ≥ -7

From the question, we are to determine the linear function that have minimum value but no maximum value

The decreasing function f(x) = 10 - 3x over the domain x ≤ 9 has a minimum value but no maximum value.

Domain: x ≤ 9

This function is decreasing since the slope is negative.

The minimum value occurs at x = 9, where f(9) = 10 - 3(9) = -17.

Since the slope is negative, the function continues to decrease without bound as x approaches negative infinity.

The decreasing function f(x) = 5x - 1 over the domain x ≥ -7 has a minimum value but no maximum value.

Domain: x ≥ -7

This function is increasing since the slope is positive.

The minimum value occurs at x = -7, where f(-7) = 5(-7) - 1 = -36.

Since the slope is positive, the function continues to increase without bound as x approaches positive infinity.

Hence, the functions are:

f(x) = 10 - 3x over the domain x ≤ 9

f(x) = 5x - 1 over the domain x ≥ -7

The probability that a hotel room costs $227 or more per night in New York City is 0.3406.

It is a branch of mathematics that deals with the occurrence of a random event.

Lets standardize the value of $227 per night using the formula:

z = (x - μ) / σ

where x is the value we are interested in, μ is the mean of the distribution, and σ is the standard deviation of the distribution. Substituting the given values, we get:

z = (227 - 205) / 54

z = 0.4074

We need to find the probability that a hotel room costs $227 or more per night, which is equivalent to finding the probability that a standardized value is greater than or equal to 0.4074.

Using a standard normal table, we find:

P(Z ≥ 0.4074) = 1 - P(Z < 0.4074)

P(Z ≥ 0.4074) = 1 - 0.6594

P(Z ≥ 0.4074) = 0.3406

Therefore, the probability that a hotel room costs $227 or more per night in New York City is approximately 0.3406.

The probability that a hotel room costs $227 or more per night is 0.3446

Probability distribution yields the possible outcomes for any random event. It is also defined based on the underlying sample space as a set of possible outcomes of any random experiment. These settings could be a set of real numbers or a set of vectors or a set of any entities. It is a part of probability and statistics.

Random experiments are defined as the result of an experiment, whose outcome cannot be predicted. Suppose, if we toss a coin, we cannot predict, what outcome it will appear either it will come as Head or as Tail. The possible result of a random experiment is called an outcome. And the set of outcomes is called a sample point. With the help of these experiments or events, we can always create a probability pattern table in terms of variables and probabilities.

The population will reach 7 million people approximately 21.67 years after 2002. Rounding to the nearest whole number, this corresponds to the year 2024.

The year when the population reaches 7 million can be determined using the population model given, f(x) = 6.7(1.0032)x, where x is the number of years following 2002.

When we solve for x while setting f(x) equal to 7, we obtain:

[tex]7 = 6.7(1.0032)^x[/tex]

By multiplying both sides by 6.7, we obtain:

[tex]1.04478 = 1.0032^x[/tex]

When we take the natural logarithm of both sides, we obtain:

ln(1.04478) = x * ln (1.0032)

After finding x, we obtain:

x = ln(1.04478) / ln (1.0032)

x ≈ 21.67

Hence, approximately 21.67 years after 2002, the population will reach 7 million. This corresponds to the year 2024 when rounded to the next whole number.

To find the value of k for which the matrix A has one eigenvalue of multiplicity 2, we can use the characteristic equation of the matrix. The characteristic equation is det(A-λI)=0. For a given matrix, this equation will yield a polynomial equation of degree equal to the dimension of the matrix.

In this case, the equation is (λ+4)(λ-2) = 0. Solving this equation gives us two distinct eigenvalues of λ= -4 and λ=2. This means that for any value of k, the matrix A will have two distinct eigenvalues, and thus cannot have one eigenvalue of multiplicity 2.

In an equilateral triangle,

Each angle = 60°

∴ a + a + 100° = 180°

⇒ 2a + 100° = 180°

⇒ 2a = 180° – 100° = 80°

∴ a = 80°/2 = 40° ∴ x = 60° + 40° = 100°

And y = 60° + 40° = 100°

An equilateral triangle in geometry is a triangle with equally long sides. The three angles opposite the three equal sides are equal in size because the three sides are equal. As a result, with each angle measuring 60 degrees, it is sometimes referred to as an equiangular triangle. Equilateral triangles have the same area, perimeter, and height formula as other kinds of triangles.

An equilateral triangle has a predictable shape. By combining the words "Equi" (which means equal) and "Lateral," which refers to sides, the word "Equilateral" is created. Due to the equality of its sides, an equilateral triangle is also known as a regular polygon or regular triangle.

If the values of A and B make the equation 35x – 29/x²-3x+2 = A/x-1 +b/x-2 true for all values of x for which it is defined, A+B is 35.

The given equation is 35x - 29/(x² - 3x + 2) = A/(x - 1) + B/(x - 2).

We can simplify the denominator of the second term on the left hand side by factoring it:

35x - 29/[(x - 1)(x - 2)] = A/(x - 1) + B/(x - 2)

Now, we can multiply both sides of the equation by (x - 1)(x - 2) to get rid of the fractions:

35x(x - 1)(x - 2) - 29 = A(x - 2) + B(x - 1)

Expanding the left hand side gives us:

35x³ - 70x² + 35x - 29 = A(x - 2) + B(x - 1)

Now, we can compare the coefficients of x on both sides of the equation to find the values of A and B. The coefficient of x on the left hand side is 35, and on the right hand side it is A + B. Therefore, A + B = 35.


Therefore, the values of A and B make the equation 35x – 29/x^2-3x+2 = A/x-1 +b/x-2 true for all values of x for which it is defined is 35.
