Step-by-step explanation:

Assume, that the number is x

Let's write an equation according to the given information:

\(2x = {x}^{2} \)

\( {x}^{2} - 2x = 0\)

Let's solve this incomplete quadratic equation:

\(x(x - 2) = 0\)

x = 0 or x - 2 = 0

x = 2

Since O isn't a natural number, the answer is 2

Answer:

Each will receive \(\frac{1}{6}th\) of the cake.

Step-by-step explanation:

Let the amount of cake = c

Lisa, Juan and Isaac are the persons who are sharing half of a cake equally.

Number of persons = 3

Part of the cake shared = \(\frac{c}{2}\)

Fraction of the cake shared by each = \(\frac{\text{Amount of cake shared}}{\text{Number of persons who shared}}\)

                                                             = \(\frac{\frac{1}{2}c}{3}\)

                                                             = \(\frac{1}{6}c\)

Therefore, fraction of total cake shared by each member will be \(\frac{1}{6}\) of the total amount of cake.

The midpoint between the endpoints (9, -1) and (1, 15) is equal to (5, 7).

In order to determine the midpoint of a line segment with two (2) endpoints, we would add each point together and divide by two (2).

Midpoint = [(x₁ + x₂)/2, (y₁ + y₂)/2]

Substituting the given parameters into the midpoint of a line segment formula, we have the following;

Midpoint = [(x₁ + x₂)/2, (y₁ + y₂)/2]

Midpoint = [(9 + 1)/2, ((-1) + 15)/2]

Midpoint = [(10)/2, (14)/2]

Midpoint = (5, 7).

Answer:

\(\frac{7}{15}\)

Step-by-step explanation:

Given

\(\frac{16-4(5)}{2(6)+8}\) + \(\frac{2}{3}\)

= \(\frac{16-20}{12+8}\) + \(\frac{2}{3}\)

= \(\frac{-4}{20}\) + \(\frac{2}{3}\)

= - \(\frac{1}{5}\) + \(\frac{2}{3}\)

We require the fractions to have a common denominator of 15

Multiply the numerator/ denominator of - \(\frac{1}{5}\) by 3 and

Multiply the numerator/ denominator of \(\frac{2}{3}\) by 5

= - \(\frac{3}{15}\) + \(\frac{10}{15}\)

= \(\frac{7}{15}\)

The gradient vector field F generated by the function ϕ(x,y)=x2 + y2Consider the curve r(t)=⟨t2, e2t⟩ and let θ be the angle between F and T(t), the unit tangent vector for r(t), at time t=2. cos(θ) = √(2/(2 + e4)).

To compute the gradient vector field of a scalar function, use the formula \(\nabla \phi\), where \(\nabla\) is the gradient operator, which can be expressed as a vector.\[\nabla \phi

= \langle \frac{\partial \phi}{\partial x}, \frac{\partial \phi}{\partial y} \rangle\]The gradient vector field F generated by the function

ϕ(x,y)=x2 + y2 is given by,

\[\nabla \phi = \langle 2x, 2y \rangle

= 2\langle x, y \rangle\]Now, find the unit tangent vector T(t),

which is given by the derivative of the curve r(t), normalized by its magnitude.

\[T(t) = \frac{r'(t)}{\|r'(t)\|}

= \frac{\langle 2t, 2e^{2t} \rangle}{\sqrt{4t^2 + 4e^{4t}}}

= \frac{1}{\sqrt{t^2 + e^{4t}}}\langle t, e^{2t} \rangle\]Thus, \[T(2)

= \frac{1}{\sqrt{4 + e^4}}\langle 2, e^4 \rangle

= \langle \frac{2}{\sqrt{4 + e^4}}, \frac{e^4}{\sqrt{4 + e^4}} \rangle\]

Finally, find cos(θ) by taking the dot product of F and T(t).\[F(2)

= 2\langle 2, 0 \rangle

= \langle 4, 0 \rangle\]Hence,\[\cos \theta

= \frac{F(2)\cdot T(2)}{\|F(2)\|\|T(2)\|}

= \frac{8/\sqrt{4 + e^4}}{4/\sqrt{2 + e^4}}

= \sqrt{\frac{2}{2 + e^4}}\]

Answer:

The inverse function h(x) = 4x + 48

Step-by-step explanation:

Here, we want to find the inverse of a function

The function is;

f(x) = x/4 -12

now, let this value equals m

so;

m = x/4 -12

we now try and make x the subject formula and this gives us the inverse.

m = (x-48)/4

4m = x -48

x = 4m + 48

substitute m for x

which implies 4x + 48

This is the inverse of the function

Answer:

D. h(x) = 4x + 48

(a) To show that the magnitude of the gradient, ||▽f|| = √( (∂f/∂x)^2 + (∂f/∂y)^2 ), is isotropic, we need to demonstrate that it is independent of the direction.

Let's consider the squared magnitude of the gradient:

||▽f||^2 = (∂f/∂x)^2 + (∂f/∂y)^2

Now, let's consider a rotated coordinate system, where x' and y' axes are obtained by rotating the original x and y axes by an angle θ. In this new coordinate system, the partial derivatives can be expressed as:

∂f/∂x' = cos(θ) * (∂f/∂x) - sin(θ) * (∂f/∂y)

∂f/∂y' = sin(θ) * (∂f/∂x) + cos(θ) * (∂f/∂y)

Squaring these expressions and adding them:

(∂f/∂x')^2 + (∂f/∂y')^2 = (cos^2(θ) * (∂f/∂x)^2 - 2 * cos(θ) * sin(θ) * (∂f/∂x) * (∂f/∂y) + sin^2(θ) * (∂f/∂y)^2) + (sin^2(θ) * (∂f/∂x)^2 + 2 * cos(θ) * sin(θ) * (∂f/∂x) * (∂f/∂y) + cos^2(θ) * (∂f/∂y)^2)

= (∂f/∂x)^2 + (∂f/∂y)^2

As we can see, the squared magnitude of the gradient is the same in the original and rotated coordinate systems, indicating that the magnitude of the gradient is isotropic.

(b) The isotropic property is lost when the gradient magnitude is approximated by |▽f| ≈ |∂f/∂x| + |∂f/∂y|. This approximation assumes that the partial derivatives of f with respect to x and y are independent of each other, which may not be true in general.

For example, consider a function f(x, y) = x^2 + y^2. The gradient of this function is ▽f = (2x, 2y). The magnitude of the gradient, ||▽f||, is √(4x^2 + 4y^2) = 2√(x^2 + y^2). However, if we approximate the gradient magnitude using the given formula, we would get |▽f| ≈ |2x| + |2y| = 2|x| + 2|y|. This approximation does not accurately represent the true magnitude of the gradient and violates the isotropic property.

Therefore, when the gradient magnitude is approximated by the sum of the absolute values of the partial derivatives, the isotropic property is lost and the approximation may not provide an accurate measure of the gradient magnitude.

Mason's friends do not play video games are 4.

Mason asked some classmates whether they play video games.

The ratio of friends who play video games to everyone he asked is given as some fraction or decimal value.
Let's assume that the ratio is in the form of "x:y",

"x" represents the number of friends who play video games, and "y" represents the total number of friends that Mason asked.
To find out how many of his friends do not play video games,

To subtract the number of friends who play video games from the total number of friends that Mason asked.

This is because the remaining friends who were not counted in the "x" value of the ratio must be those who do not play video games.
So, the number of friends who do not play video games can be calculated as:
Total number of friends - Number of friends who play video games = y - x
The ratio of friends who play video games to everyone he asked is 3:7,

It means that out of 7 friends, 3 play video games, and 4 do not play video games.

The number of friends who do not play video games can be calculated as:
y - x = 7 - 3 = 4

Step-by-step explanation:

The area of the shaded region is about 100.48 square units, rounded to the nearest hundredth.

A two-dimensional surface or region can be measured using the mathematical notion of area. Common square units used to describe it include square metres, square feet, and square inches. A flat surface's area is typically calculated by multiplying its length and breadth.

To find the area of the shaded region, we need to subtract the area of the smaller circle from the area of the larger circle.

Let's first find the area of the larger circle with radius 6. The formula for the area of a circle is \(A = \pi r^2\), where A is the area and r is the radius. So, for the larger circle:

A_larger = \(\pi (6)^2\)

A_larger = \(36\pi\)

Now, let's find the area of the smaller circle with radius 2. Using the same formula, we have:

A_smaller =\(\pi (2)^2\)

A_smaller = \(4\pi\)

To find the shaded region, we subtract the area of the smaller circle from the area of the larger circle:

A_shaded = A_larger - A_smaller

A_shaded = \(36\pi - 4\pi\)

A_shaded =\(32\pi\)

To round to the nearest hundredth, we can use the approximation π ≈ 3.14:

A_shaded ≈ 32(3.14)

A_shaded ≈ 100.48

Therefore, the area of the shaded region is about 100.48 square units, rounded to the nearest hundredth.

The perimeter of the semicircular window with a radius of 20cm is the nearest tenth would be 63 cm.

What is the perimeter of the semicircle?

The perimeter of a semicircle is the total length of the curved boundary of the semicircle, which is half the circumference of the circle with the same radius. The formula for the circumference of a circle with radius r is 2πr, so the formula for the perimeter of a semicircle with radius r is:

Perimeter of semicircle = (1/2) x 2πr + 2r

= πr + 2r

= (π + 2)r

To find the perimeter of a semicircular window with a radius of 20cm, we can substitute r = 20 into the formula:

Perimeter of semicircle = (π + 2) x 20

= (3.14159 + 2) x 20

= 62.8318 cm (rounded to 4 decimal places)

Therefore, the perimeter of the semicircular window with a radius of 20cm is approximately 62.8318 cm.

Step-by-step explanation:

The given limit can be expressed as the definite integral: lim (n→∞) n ∑(i=1 to n) i⁶/n⁷ = ∫[1/n, 1] x⁶ dx

To express the given limit as a definite integral, we need to determine the appropriate function f(x) and the integration limits b and 1.

Let's start by rewriting the given limit:

lim (n→∞) (1/n) ∑(i=1 to n) \(i^6/n^7\)

Notice that the term i⁶/n⁷ can be written as (i/n)⁶/n.

Therefore, we can rewrite the above limit as:

lim (n→∞) (1/n) ∑(i=1 to n) (i/n)⁶/n

This can be further rearranged as:

lim (n→∞) (1/n^7) ∑(i=1 to n) (i/n)⁶

Now, let's define the function f(x) = x⁶, and rewrite the limit using the integral notation:

lim (n→∞) (1/n^7) ∑(i=1 to n) (i/n)⁶ = ∫[a,b] f(x) dx

To determine the integration limits a and b, we need to consider the range of values that x can take. In this case, x = i/n, and as i varies from 1 to n, x varies from 1/n to 1. Therefore, we have a = 1/n and b = 1.

Hence, the given limit can be expressed as the definite integral:

lim (n→∞) n ∑(i=1 to n) i⁶/n⁷ = ∫[1/n, 1] x⁶ dx

C = (-2, 3)

If we translate the points 5 units to the right then the changed coordinates will be -

B' = (-2 + 5, 6) = (3, 6)

C' = (-2 + 5, 3) = (3, 3)
