Answer:

B

Step-by-step explanation:

The absolute value function always gives a positive result

However, the expression inside can be positive or negative

| 2x - 4 | = 10

2x - 4 = 10 ← positive expression

2x - 4 = - 10 ← negative expression

Solving both gives

2x - 4 = 10 ( add 4 to both sides )

2x = 14 ( divide both sides by 2 )

x = 7

and

2x - 4 = - 10 ( add 4 to both sides )

2x = - 6 ( divide both sides by 2 )

x = - 3

The correct option is option B i.e., 2x−4 = 10 and 2x−4 = −10 and the values will be x = 7 and x = -3 respectively.

It is given that an equation is | 2x - 4 | = 10 .

The objective is to maximize the expression z = 7x1 - 5x2 - 2x3, subject to two constraints.. The goal is to find the values of x1, x2, and x3 that maximize the objective function while satisfying the given constraints.

In the primal problem, the objective is to maximize the expression z, which is a linear combination of the decision variables x1, x2, and x3. The coefficients 7, -5, and -2 represent the weights assigned to each variable in the objective function. The constraints represent the relationships and limitations imposed on the variables. The first constraint is an equality constraint, which means that the left-hand side of the equation must equal the right-hand side. The second constraint is an inequality constraint, indicating that the value of the expression 2x1 + x2 must be less than or equal to a certain value.

To solve this linear programming problem, various optimization techniques such as the simplex method or interior point methods can be applied. These methods iteratively adjust the values of the decision variables to find the optimal solution that maximizes the objective function while satisfying the given constraints.

Answer:

We conclude that:

f(g(3)) = 2

Hence, option B is correct.

Step-by-step explanation:

Given the f(x) table

x         2          3            4          5

f(x)      0           1             2         3

Given the g(x) table

x         1           2           3            4

g(x)      1           2            4           8

We need to determine f(g(3)).

In order to determine f(g(3)), first, we need to determine g(3)

It is clear from the table of g(x),

at x = 3, g(3) = 4

so

f(g(3)) = f(4)

Now, we need to check the value of f(4) at x = 4 using the table f(x)

It is clear from the table of f(x),

at x = 4, f(4) = 2

Thus,

f(g(3)) = f(4) = 2

Therefore, we conclude that:

f(g(3)) = 2

Hence, option B is correct.

Multiply both sides by 5:

5(5)=5(\(\frac{2}{5}\)a)

Divide both sides by 2:

We have shown that for every A ∈ C^(n×N), we have ∥A∥^2 = max(λ∈Σ(A^H A)) λ. To show that for every A ∈ C^(n×N), we have ∥A∥^2 = max(λ∈Σ(A^H A)) λ, where Σ(A^H A) denotes the set of eigenvalues of the Hermitian matrix A^H A, we can use the following steps:

First, note that ∥A∥^2 = tr(A^H A), where tr denotes the trace of a matrix.

Next, observe that A^H A is a Hermitian positive semidefinite matrix, which means that it has only non-negative real eigenvalues. Let λ_1, λ_2, ..., λ_k be the distinct eigenvalues of A^H A, with algebraic multiplicities m_1, m_2, ..., m_k, respectively.

Then we have:

tr(A^H A) = λ_1 + λ_2 + ... + λ_k

= (m_1 λ_1) + (m_2 λ_2) + ... + (m_k λ_k)

≤ (m_1 λ_1) + 2(m_2 λ_2) + ... + k(m_k λ_k)

= tr(k Σ(A^H A))

where the inequality follows from the fact that λ_i ≥ 0 for all i and the rearrangement inequality.

Note that k Σ(A^H A) is a positive definite matrix, since it is the sum of k positive definite matrices.

Therefore, by the Courant-Fischer-Weyl min-max principle, we have:

max(λ∈Σ(A^H A)) λ ≤ max(λ∈Σ(k Σ(A^H A))) λ

= max(λ∈Σ(A^H A)) k λ

= k max(λ∈Σ(A^H A)) λ

Combining steps 3 and 5, we get:

∥A∥^2 = tr(A^H A) ≤ k max(λ∈Σ(A^H A)) λ

Finally, note that the inequality in step 6 is sharp when A has full column rank (i.e., k = N), since in this case, A^H A is positive definite and has exactly N non-zero eigenvalues.

Therefore, we have shown that for every A ∈ C^(n×N), we have ∥A∥^2 = max(λ∈Σ(A^H A)) λ.

Answer :

1. We are given with a parallelogram whose opposite sides are :-

We know that opposite sides and angles of the parallelogram are equal.

PS = RQ

\( \implies \sf \: (-1 + 4x) = (3x + 3) \\ \)

\( \implies \sf \: 4x - 3x = 3 + 1\\ \)

\( \implies \sf \: x = 4 \\ \)

Length of RQ is (3x + 3)

Substituting value of x = 4 in RQ.

\( \implies \sf \: (3x +3) \\ \)

\( \implies \sf \: 3(4) + 3 \\ \)

\( \implies \sf \: 12 + 3 \\ \)

\( \implies \sf \: 15 \\ \)

Therefore, Length of RQ will be 15

2. Find \( \sf \angle G \)

We are given with :-

Since, Opposite angles of parallelogram are also equal :

\(\angle G = \angle E \\ \)

\(\implies \sf \: 5x -9 = 3x + 11 \\ \)

\(\implies \sf \: 5x - 3x = 11 +9 \\ \)

\( \implies \sf \: 2x = 20 \\ \)

\( \implies \sf \: x = \dfrac{20}{10} \\ \)

\( \implies \sf \: x = 10 \\ \)

Since \( \sf \angle G \) is 5x - 9.

Substituting value of (x = 10) in \( \sf \angle G \)

\( \implies \sf \: 5(10) - 9 \\ \)

\( \implies \sf \: 50 -9 \\ \)

\( \implies \sf \: 41 \\ \)

Therefore, \( \sf \angle G \) is 41.

19. QR = 15 units.

20. m ∡G=41°

Step-by-step explanation:

The properties of a parallelogram are:

Question No. 19.

We know that the opposite side of parallelogram is equal, So

PS=QR

-1+4x=3x+3

First of all we will find the value of x.

-1 + 4x = 3x + 3

Subtracting 3x from both sides, we get:

x - 1 = 3

Adding 1 to both sides, we get:

x = 4

SO, QR=3*4+3=15

Side QR is 15 units.

Question No. 20.

We know that the opposite angle of parallelogram is equal, So

EF=GD

3x+11=5x-9
Subtracting 3x from both sides:

3x + 11 - 3x = 5x - 9 - 3x

11 = 2x - 9

Next, we can add 9 to both sides to isolate the variable term on one side:

11 + 9 = 2x - 9 + 9

20 = 2x

Finally, we can solve for x by dividing both sides by 2:

20/2 = 2x/2

x=10

Now

m ∡G=5x-9=5*10-9=41°

therefore m ∡G=41°

While flood recurrence and probability graphs can provide valuable information on the frequency and severity of major floods, it is important to consider the impact of urbanization and other factors that can affect the accuracy of these predictions.

Urbanization can have a significant impact on the reliability of using flood recurrence and probability graphs to calculate the frequency and severity of major floods. As cities expand and become more developed, the natural landscape is altered in various ways, including the creation of impervious surfaces such as pavement and buildings, which reduce the amount of water that can be absorbed into the ground. This can lead to increased runoff during heavy rainfall events and higher flood peaks.

Furthermore, urbanization can also change the flow patterns of rivers and streams, as well as affect the drainage systems and infrastructure of cities. As a result, the historic records used to create flood recurrence and probability graphs may no longer accurately reflect the current and future flood risks in urban areas.

In addition, climate change can further complicate the reliability of using these graphs, as it can lead to changes in precipitation patterns, sea level rise, and other factors that can affect the frequency and severity of floods.

Therefore, while flood recurrence and probability graphs can provide valuable information on the frequency and severity of major floods, it is important to consider the impact of urbanization and other factors that can affect the accuracy of these predictions.

If baskets B and C are on the same indifference curve and preferences satisfy all four of the basic assumptions in economics, it means that the individual considers both baskets equally preferable and is indifferent between them.

In economics, an indifference curve represents a set of combinations of goods or baskets that provide the same level of utility or satisfaction to an individual. If baskets B and C are on the same indifference curve, it means that the individual derives the same level of satisfaction from both baskets.

The four basic assumptions in economics regarding preferences are completeness, transitivity, more is better, and diminishing marginal rate of substitution. Completeness assumes that individuals can rank any two baskets in terms of preference. Transitivity suggests that if an individual prefers basket A to B and basket B to C, then the individual also prefers basket A to C. The assumption of "more is better" implies that individuals prefer more of a good to less. Diminishing marginal rate of substitution posits that as an individual consumes more of one good, they are willing to give up less of the other good to maintain the same level of satisfaction.

She must deposit approximately \($826,920.01\) at the end of each quarter, and the interest earned will be approximately \($673,079.99\).

Desired accumulated amount (A) = \($1,500,000\)

Annual interest rate (r) = 8% or 0.08

Number of compounding periods per year (n) = 4 (quarterly compounding)

Number of years (t) = 10

To find the deposit amount (P), we can use the formula:

\(\[ P = \frac{A}{\left(1 + \frac{r}{n}\right)^{nt}} \]\)

Let's substitute the given values and calculate P:

\(\[ P = \frac{1,500,000}{\left(1 + \frac{0.08}{4}\right)^{4 \times 10}} \]\)

Simplifying further:

\(\[ P = \frac{1,500,000}{(1.02)^{40}} \]\)

\(\[ P \approx \frac{1,500,000}{1.818446957} \approx 826,920.01 \]\)

The deposit amount (P) is approximate \($826,920.01\).

To calculate the interest earned, we can subtract the total deposit amount from the desired accumulated amount:

\(\[ \text{Interest Earned} = A - \text{Total Deposit} = 1,500,000 - 826,920.01 \approx 673,079.99 \]\)

The interest earned is approximate \($673,079.99\).

Therefore, she must deposit approximately \($826,920.01\) at the end of each quarter to accumulate \($1,500,000\) after 10 years. The interest earned will be approximately \($673,079.99\).
