Step-by-step explanation:

For two lines to be parallel to each other, it means they have to have the same slope. So, the question is really asking for the line through $(8, 5)$ that has the same slope as the line shown.

We can start by finding the slope of the line shown. Recall that given two points $(x_{1}, y_{1})$ and $(x_{2}, y_{2})$, the slope of the line between them is $\frac{y_{2}-y_{1}}{x_{2}-x{1}}$, or more commonly remembered as rise over run. Plugging in the points $(-3, 1)$ and $(6, -1)$ into the equation for the slope, we see that the slope of the line shown is $\frac{-1-1}{6-(-3)}=\frac{-2}{9}$.

We recall that the point-slope form of a line is such that given a point $(x_{1}, y_{1})$ and the slope $m$, the equation for a line with that slope through the given point is $y-y_{1}=m(x-x_{1})$(Note: divide by $x-x_{1}$. What does that remind you of?). Plugging in our point and slope, we have that the equation for the line we want is $y-5=\frac{-2}{9}(x-8)$. Expanding the right-hand side gives $y-5=\frac{-2}{9}x+\frac{16}{9}$.

Adding $5$ to both sides gives the desired $\boxed{y=\frac{-2}{9}x+\frac{61}}$

A set of simultaneous equations, often known as a system of equations or an equation system, is a finite collection of equations for which common solutions are sought.

Inconsistent System

For a system of equations to have no real solution, the lines of the equations must be parallel to each other.

Consistent System

1. Dependent Consistent System

For a system of the equation to be a Dependent Consistent System, the system must have multiple solutions for which the lines of the equation must be coinciding.

2. Independent Consistent System

For a system of the equation to be an Independent Consistent System, the system must have one unique solution for which the lines of the equation must intersect at a particular.

The solution of the two of the given function will be when the graph of the two the function will intersect with each other.

Using the graph the solutions are (1.791,11.374) and (-2.791, -2.374).

The probability of more than one tornado during a day is approximately 0.1219 or 12.19%.

To compute the probability of more than one tornado during a day, we need to use a Poisson distribution. The Poisson distribution is used to model the number of events that occur in a fixed interval of time, given the average rate of occurrence. In this case, the average rate of occurrence is 18 tornadoes per 30 days, or 0.6 tornadoes per day.

Let X be the random variable representing the number of tornadoes in a day. Then, X follows a Poisson distribution with parameter λ = 0.6. The probability of more than one tornado in a day can be computed as follows:

P(X > 1) = 1 - P(X ≤ 1)

= 1 - [P(X = 0) + P(X = 1)]

= 1 - [e^(-λ) * (λ^0 / 0!) + e^(-λ) * (λ^1 / 1!)]

= 1 - [e^(-0.6) * (0.6^0 / 0!) + e^(-0.6) * (0.6^1 / 1!)]

= 1 - [0.5488 + 0.3293]

= 0.1219

Therefore, the probability of more than one tornado during a day is approximately 0.1219 or 12.19%.

Standard form: \(3t^8\)

Degree: 8

Leading coefficient: 3

Classification: This is a monomial, as it has only one term.

What is leading coefficient?

In a polynomial expression, the leading coefficient is the coefficient of the term with the highest degree, i.e., the term with the greatest exponent.

To write a polynomial in standard form means to arrange its terms in descending order of degree and write the coefficients in front of each term.

The given polynomial, \(3t^8\), is already in standard form since it has only one term, which is in descending order of degree.

The leading coefficient is the coefficient of the term with the highest degree, which is 3 in this case.

Since the polynomial has only one term, it is classified as a monomial.

Therefore, we can say that the polynomial is a monomial of degree 8 with a leading coefficient of 3.

If a differentiable function f: ℝ³ ⟶ ℝ has an absolute maximum value K ≠ 0 and an absolute minimum m, then the function f must have a critical point where the derivative of the function is zero (or undefined).

Given that, suppose f : ℝ³ ⟶ ℝ is a differentiable function which has an absolute maximum value K ≠ 0 and an absolute minimum m.

Since f is continuous on a compact set, it follows that f has a global maximum and a global minimum. We are given that f has an absolute maximum value K ≠ 0 and an absolute minimum m. Then there exists a point a ∈ ℝ³ such that f(a) = K and a point b ∈ ℝ³ such that f(b) = m.Then f(x) ≤ K and f(x) ≥ m for all x ∈ ℝ³.

Since f(x) ≤ K, it follows that there exists a sequence {x_n} ⊆ ℝ³ such that f(x_n) → K as n → ∞. Similarly, since f(x) ≥ m, it follows that there exists a sequence {y_n} ⊆ ℝ³ such that f(y_n) → m as n → ∞.Since ℝ³ is a compact set, there exists a subsequence {x_nk} and a subsequence {y_nk} that converge to points a' and b' respectively. Since f is continuous, it follows that f(a') = K and f(b') = m.

Since a' is a limit point of {x_nk}, it follows that a' is a critical point of f, i.e., ∇f(a') = 0 (or undefined). Similarly, b' is a critical point of f. Therefore, f has at least two critical points where the derivative of the function is zero (or undefined). Hence, the statement is true.

Therefore, the above explanation is verified that if a differentiable function f: ℝ³ ⟶ ℝ has an absolute maximum value K ≠ 0 and an absolute minimum m, then the function f must have a critical point where the derivative of the function is zero (or undefined).

The parametric equation of a tangent line is x(t) = 1+t, y(t) = t, z(t) = 1.

What is the parametric equation?

A parametric equation is a sort of equation that uses an independent variable known as a parameter (commonly indicated by t) and in which dependent variables are expressed as continuous functions of the parameter and are not reliant on another variable.

Here, we have

Given: x = \(e^{t}\) ,y = t\(e^{t}\) ,z = t\(e^{t^2}\) ; (1,0,0)

We have to find the parametric equations for the tangent line to the curve.

r(t) = <  \(e^{t}\) , t\(e^{t}\) , t\(e^{t^2}\)>

For, t = 0

r(0) = <1, 0, 0>

Now, we differentiate r(t) with respect to t and we get

r'(t) = < \(e^{t}\), \(e^{t} +te^{t}\), \(e^{t^2}+2t^2 e^{t^2}\)>

At (1,0,0) , t = 0

r'(t) = < 1, 1, 1>

The equation of tangent line is given by:

<x(t),y(t),z(t)> =<1,0,0> + <1,1,1>t

= <1,0,0> + <t,t,t>

= <1+t,t,t>

Hence, the parametric equation of a tangent line is x(t) = 1+t, y(t) = t, z(t) = 1.

Step-by-step explanation:

The rectangular form of a complex number is represented by the following formula:

\(z = a+i\,b\) (1)

Where each coefficient can be determined as function of the polar components:

\(a = r\cdot \cos \theta\) (2)

\(b = r\cdot \sin \theta\) (3)

Where:

\(r\) - Magnitude of the complex number, dimensionless.

\(\theta\) - Direction of the complex number, measured in radians.

If we know that \(r = 40\) and \(\theta = \frac{7\pi}{6}\), then the rectangular form of the number is:

\(a = 40\cdot \cos \frac{7\pi}{6}\)

\(a = -20\sqrt{3}\)

\(b = 40\cdot \sin \frac{7\pi}{6}\)

\(b = -20\)

The rectangular form of \(z=40\cdot\left(\cos \frac{7\pi}{6}+i\,\sin \frac{7\pi}{6}\right)\) is \(z = -20\sqrt{3}-i\,20\). The correct answer is C.

Step-by-step explanation:

Given that :

Net income = 53246

Deduction (tax purposes) % = 21%

Gross income = net income + deduction

Let gross income = x

x = 53246 + 21% of x

x = 53246 + 0.21x

x - 0.21x = 53246

0.79x = 53246

x = 53246 / 0.79

x = 67400

C(x + 4)^3(x - 2). The value of M is 18.  

To find the value of M in the integral ∫ M (12x + 30) / (x^2 + 2x - 8) dx, we need to evaluate the integral and determine the value of M.

First, let's simplify the integrand:

∫ (12x + 30) / (x^2 + 2x - 8) dx

To simplify the denominator, we factorize it:

x^2 + 2x - 8 = (x + 4)(x - 2)

Now, we can rewrite the integral as:

∫ (12x + 30) / [(x + 4)(x - 2)] dx

To evaluate this integral, we can use partial fraction decomposition. Assuming that the integral can be expressed as:

∫ [(A / (x + 4)) + (B / (x - 2))] dx

By equating the numerators, we have:

12x + 30 = A(x - 2) + B(x + 4)

Expanding and collecting like terms, we get:

12x + 30 = (A + B) x + (-2A + 4B)

By comparing coefficients, we obtain the following system of equations:

A + B = 12 (equation 1)

-2A + 4B = 30 (equation 2)

Solving this system of equations, we find A = -6 and B = 18.

Now, we can rewrite the integral as:

∫ [(-6 / (x + 4)) + (18 / (x - 2))] dx

Integrating each term separately, we get:

-6 ∫ (1 / (x + 4)) dx + 18 ∫ (1 / (x - 2)) dx

Applying the natural logarithm integration rule, we have:

-6 ln| x + 4 | + 18 ln| x - 2 | + C
