- (5x + 7) >= 17

you must have heard that the direction of inequality gets inverted when the signs of equations on both sides is inverted.

so,

5x + 7 <= - 17

5x + 7 - 7 <= -17 - 7

5x <= - 24

x <= -24/ 5

so, the value of x can be less than or equal to -24/ 5

upon solving -24/5 we get -4.8

and the question is asking for largest integral value, then it will be - 5

check the number line for this

-6 -5 -4.8 -4 -3 -2 ....

suppose this is a number line.

the value of x lies on the left side of -4.8 and -4.8 is not an integer so we'll skip onto -5 which is the following integer on the required side.

so the answer is -5

Let f(x) = mx+b. Also, let g(x) be the inverse of f(x)

To find the inverse, we start with y = mx+b and swap x and y. From there, we solve for y like so

y = mx+b

x = my + b

x-b = my

my = x-b

y = (x-b)/m ... note m is in the denominator, so m cannot be 0

y = (x/m) - (b/m)

y = (1/m)x - (b/m)

g(x) = (1/m)x - (b/m)

This new equation is linear because it is in the form (slope)x+(y intercept)

The new slope is 1/m and the new y intercept is -b/m

So this proves that the inverse g(x) is linear when f(x) is linear.

The inverse function is:

\(y = \frac{x}{m} - \frac{b}{m}\)

Since \(m \neq 0\) and \(x \neq b\), it is a linear function with slope \(\frac{1}{m}\) and intercept \(-\frac{b}{m}\).

---------------------------------

\(y = mx + b\)

In which:

\(x = my + b\)

\(my = x - b\)

\(y = \frac{x}{m} - \frac{b}{m}\)

Since \(m \neq 0\) and \(x \neq b\), it is a linear function with slope \(\frac{1}{m}\) and intercept \(-\frac{b}{m}\).

(a) No, the function g is not injective.

(b) No, the function g is not surjective.

Given, g(x) = x², where R denotes the set of all real numbers and R+ denotes the set of all non-negative real numbers.

(a) To prove that g is injective or not injective, let's check for x₁, x₂ ε R such that g(x₁) = g(x₂) ⇒ x₁² = x₂².

Then, x₁ = x₂ or x₁ = - x₂. So, the function g is not injective because there exist two values, x₁ and x₂, that have the same image, that is,

g(x₁) = g(x₂), but x₁ ≠ x₂. Let's understand this with an example; if g(2) = 4 and g(-2) = 4, then x₁ = 2 and x₂ = - 2, that is, both values have the same image. Hence, the given function g is not injective.

(b) Now, let's check for surjective.

Let y ε R⁺, then g(x) = y has a solution x ε R⁺ or x = -x, that is x = √y or x = -√y. Thus, the given function g is not surjective because it does not have solutions for y ε R. The domain is R, and the range is R⁺, which implies that the function is not surjective because it does not cover all of the range values. Therefore, g is not surjective.

Step-by-step explanation:

Distance = 13 units

Point A: (8, -7)

Point B: (-4, -2)

\(\sqrt{(8 + 4)^{2} + (-7 + 2)^{2} }\)

\(\sqrt{(12)^{2} + (-5)^{2} }\)

\(\sqrt{144 + 25 }\)

\(\sqrt{169}\)

\(13\)

Answer:

\(\boxed {d = 13}\)

Step-by-step explanation:

Use the Distance Formula to help you find the distance between the two following points:

\(d = \sqrt{(x_{2} - x_{1})^{2} + (y_{2} - y_{1})^{2}}\)

(where \((x_{1}, y_{1})\) represents the first point and \((x_{2}, y_{2})\) represents the second point)

-Apply the two following onto the formula:

\((x_{1}, y_{1}) = (8, -7)\)

\((x_{2}, y_{2}) = (-4, -2)\)

\(d = \sqrt{(-4 - 8)^{2} + (-2 + 7)^{2}}\)

-Solve for the distance:

\(d = \sqrt{(-4 - 8)^{2} + (-2 + 7)^{2}}\)

\(d = \sqrt{(-12)^{2} + 5^{2}}\)

\(d = \sqrt{144 + 25}\)

\(d = \sqrt{169}\)

\(\boxed {d = 13}\)

Therefore, the distance is \(13\).

The sailor must sail approximately 102.4 km and 58.9° west of due north to reach the original destination. we have used the Pythagorean theorem

To determine the distance and direction the sailor must sail to reach the original destination, we can use the concept of vector addition.

The initial displacement of the sailor is a combination of a northward displacement of 95.0 km and an eastward displacement of 35.0 km. To find the resultant displacement, we can use the Pythagorean theorem:

Resultant displacement = √((northward displacement)^2 + (eastward displacement)^2)

                   = √((95.0 km)^2 + (35.0 km)^2)

                   ≈ 102.4 km

The direction of the resultant displacement can be found using trigonometric functions. We can use the inverse tangent function to find the angle:

θ = tan^(-1)((eastward displacement) / (northward displacement))

  = tan^(-1)(35.0 km / 95.0 km)

  ≈ 20.9°

However, since we are asked to find the direction west of due north, we need to subtract this angle from 90°:

Direction = 90° - 20.9°

           ≈ 69.1°

Therefore, the sailor must sail approximately 102.4 km and 58.9° west of due north to reach the original destination.

While looking at the critical points of a function f(x) is a useful first step in finding its maxima and minima, it is not enough by itself to determine all of them.

The statement is partially correct. If a function f(x) is continuous on a closed interval, it is possible to find its absolute maxima and minima by looking at the points where f'(x) = 0, but this is not enough to guarantee that you have found all of them.

The reason why this is the case is because the condition f'(x) = 0 only identifies critical points, which are points where the function may have an extremum (either a maximum or a minimum). To determine whether a critical point is indeed a maximum or a minimum, you need to analyze the behavior of the function near the critical point.

One way to do this is by using the second derivative test, which states that if f(x) is twice differentiable and f''(x) > 0 at a critical point x, then f(x) has a local minimum at x. Similarly, if f''(x) < 0 at a critical point x, then f(x) has a local maximum at x.

You also need to use additional tools, such as the second derivative test, to verify whether the critical points are indeed extrema.

To find an orthogonal diagonalization for the matrix A = [-4, 0, 0; -3, 1, 0; -3, 0, 1], we need to find an orthogonal matrix U and a diagonal matrix D such that A = UDUᵀ.

First, find the eigenvalues of A by solving the characteristic equation |A - λI| = 0: λ₁ = -4, λ₂ = 1, λ₃ = 1.
Next, find the corresponding eigenvectors for each eigenvalue:
- For λ₁ = -4, v₁ = [1, -1, -1].
- For λ₂ = 1, v₂ = [0, 1, 0].
- For λ₃ = 1, v₃ = [0, 0, 1].
Now, normalize the eigenvectors:
- v₁_norm = [1/√3, -1/√3, -1/√3].
- v₂_norm = [0, 1, 0].
- v₃_norm = [0, 0, 1].
Form the orthogonal matrix U using the normalized eigenvectors as columns:
U = [1/√3, 0, 0; -1/√3, 1, 0; -1/√3, 0, 1].
Form the diagonal matrix D with the eigenvalues on the diagonal:
D = [-4, 0, 0; 0, 1, 0; 0, 0, 1].
So, the orthogonal diagonalization of A is given by A = UDUᵀ with U and D as above.

Answer:

1.  x = 47°

2.  c = 47°

Step-by-step explanation:

Triangle DEF is an isosceles triangle since it has two sides of equal length.

The two equal sides are called the legs and the angle between them is called the vertex angle.  Therefore, the vertex angle of ΔDEF is ∠D.

The side opposite the vertex angle is called the base (EF) and base angles are equal:

⇒ m∠F = m∠E

⇒ x = 47°

Triangle STU is an isosceles triangle since it has two sides of equal length.

The two equal sides are called the legs and the angle between them is called the vertex angle.  Therefore, the vertex angle of STU is ∠T.

The side opposite the vertex angle is called the base (SU) and base angles are equal.

As the interior angles of a triangle sum to 180° and the base angles are equal:

⇒ m∠S + m∠T + m∠U = 180°

⇒ c + 86° + c = 180°

⇒ 2c = 94°

⇒ c = 47°

For each of the given models, we will calculate the long-run effect of a one-time, one unit jump in xt​ on y.

a) The long-run effect of xt​ on y in Model 3a is 1.2.

b) The long-run effect of xt​ on y in Model 3b is 0.6.

c) The long-run effect of xt​ on y in Model 3c is not directly identifiable.

In Model 3a, the coefficient of xt​ is 1.2. This means that a one unit increase in xt​ leads to a 1.2 unit increase in y in the long run. The coefficient represents the long-run effect because it captures the average change in y when xt​ changes by one unit, holding other variables constant.

In Model 3b, the coefficient of xt​ is 0.6. This means that a one unit increase in xt​ leads to a 0.6 unit increase in y in the long run. The presence of the lagged variable xt−1​ suggests that there might be some dynamics at play, but in the long run, the effect of the current value of xt​ on y is 0.6.

In Model 3c, there is a feedback loop as yt−1​ appears on the right-hand side. This makes it difficult to isolate the direct long-run effect of xt​ on y. The coefficient of xt​, which is 0.6, represents the contemporaneous effect, but it does not capture the long-run effect alone. To quantify the long-run effect, additional techniques such as dynamic simulations or instrumental variable approaches may be required.

The equation correctly relates the total cost y to rent the washer for x days is option (B) Y = 40 + 20x

The rental fee of $40 is charged regardless of the number of days the power washer is rented. In addition to this fee, there is a daily charge of $20 per day.

Therefore, the total cost of renting the power washer for x days can be calculated by multiplying the daily charge by the number of days rented and adding the rental fee:

Total cost = (daily charge) x (number of days rented) + rental fee

Total cost = $20x + $40
