The vertex form of the equation is y = (x - 3)² - 4, which corresponds to option OD.

To convert the given equation from standard form to vertex form, we need to complete the square.

The vertex form of a parabola's equation is y = a(x-h)² + k, where (h, k) represents the vertex of the parabola.

Given equation: y = x² - 6x + 14

Move the constant term to the right side:

y - 14 = x² - 6x

Complete the square by adding and subtracting the square of half the coefficient of x:

y - 14 + 9 = x² - 6x + 9 - 9

Group the terms and factor the quadratic:

(y - 5) = (x² - 6x + 9) - 9

Rewrite the quadratic as a perfect square:

(y - 5) = (x - 3)² - 9

Simplify the equation:

y - 5 = (x - 3)² - 9

Move the constant term to the right side:

y = (x - 3)² - 9 + 5

Combine the constants:

y = (x - 3)² - 4

The solution of the heat equation subject to the boundary and the initial conditions is u(x, t) = (4π/3)sin(3πx) exp(-9π^2 kt) + (8π/6)sin(6πx) exp(-36π^2 kt).

The heat equation with the given boundary conditions is:

∂u/∂t = k ∂^2u/∂x^2

where k is a constant. We can use separation of variables to solve this equation. Let:

u(x, t) = X(x)T(t)

Substituting this into the heat equation, we get:

X(x)T'(t) = k X''(x)T(t) / X(x)T(t)

Dividing both sides by X(x)T(t) and rearranging, we get:

X''(x)/X(x) = T'(t)/(kT(t))

The left-hand side depends only on x, while the right-hand side depends only on t. Since they are equal, they must be equal to a constant:

X''(x)/X(x) = -λ

T'(t)/(kT(t)) = λ

where λ is a constant. The boundary conditions u(0,t) = u(1,t) = 0 imply that X(0) = X(1) = 0. The general solution for X(x) is then:

X(x) = A sin(nπx)

where A is a constant and n is a positive integer. The eigenvalues λ are:

λ = -(nπ)^2

The general solution for T(t) is:

T(t) = B exp(-kλt)

where B is a constant. The solution for u(x, t) is then:

u(x, t) = Σ[ A_n sin(nπx) exp(-(nπ)^2 kt) ]

where the sum is taken over all positive integers n.

We can now use the initial condition u(x,0) = 4sin3πx+8sin6πx to determine the constants A_n. Since the solution only contains sine terms, we can use the Fourier sine series to expand the initial condition:

4sin3πx+8sin6πx = Σ[ A_n sin(nπx) ]

where the sum is taken over all positive odd integers for n = 3 and all positive even integers for n = 6. The coefficients A_n are:

A_3 = 4π/3

A_6 = 16π/6

Substituting these values into the solution for u(x, t), we get:

u(x, t) = (4π/3)sin(3πx) exp(-9π^2 kt) + (8π/6)sin(6πx) exp(-36π^2 kt)

The period of simple harmonic motion will be 1.0433 sec

What is a simple harmonic motion?

In physics, simple harmonic motion is the repeated back-and-forth movement through an equilibrium, or Centre, position so that the maximum displacement on one side of this position is equal to the maximum displacement on the other. Each whole vibration occurs at the same time interval. The force driving the movement is always pointed in the direction of the equilibrium position and is inversely proportional to the separation from it. F = kx, where F is the force, x is the displacement, and k is a constant, is what this means. Hooke's law is the name of this relationship.

The vibration of a mass attached to a vertical spring, the other end of which is fixed in a ceiling, is an example of a simple harmonic oscillator.

So, the time period of Simple harmonic motion is

\(T=2\pi \sqrt{\frac{m}{k} }\)

where m is mass and k is spring constant

m = 4 pounds

k = 36lb/ft

\(T=2\pi \sqrt{\frac{4}{36} }\)

\(T=2\pi \sqrt{\frac{1}{9} }\)\(T=\frac{2\pi }{3} }\)

T=1.0433 sec

The Mean Value Theorem (MVT) is a theorem in calculus that relates the derivative of a function to the average rate of change of the function over a given interval.

The Mean Value Theorem states that if a function f is continuous on the closed interval [a, b] and differentiable on the open interval (a, b), then there exists a number c in (a, b) such that:

f'(c) = (f(b) - f(a)) / (b - a)

To find all numbers c that satisfy the conclusion of the Mean Value Theorem, we need to check if the hypotheses of the theorem are satisfied, i.e. if the function is continuous on the closed interval and differentiable on the open interval.

Without the specific function and interval provided, we cannot determine all numbers c that satisfy the conclusion of the Mean Value Theorem. Please provide more information so we can help you better.

Hi there!

\(\large\boxed{t = 12.60 \text{ days}}\)

We can solve this by setting the equation equal to 150:

\(150 = \frac{230}{1 + 56.5e^-0.37t}\)

Cross-multiply and divide:

\(150 (1 + 56.5e^{-0.37t})= 230\)

Divide both sides by 150:

\(1 + 56.5e^{-0.37t} = 1.5333\)

Isolate for t by subtracting both sides by 1 and dividing by 56.5:

\(56.5e^{-0.37t} = 0.5333\)

\(e^{-0.37t} = 0.0094395\)

Take the natural log to solve for t:

\(ln (0.0094395) = -0.37t\)

\(-4.6628522 = -0.37t\)

Divide both sides by -0.37:

t = 12.60 days.

The percentile for the data value 111 is 37.5 or 37.5th if you round down.

A percentile is a measure that represents a specific percentage of data points that fall below it in a dataset. The nth percentile in a dataset is defined as the value that is greater than n% of the data points. The percentile is a useful tool for determining how a given data point compares to the rest of the data.

For example, if a student scored in the 90th percentile on a standardized test, it means that they scored higher than 90% of all the other students who took the test. How to find the percentile? The formula for finding the percentile rank of a data point in a dataset is given as follows:

P = (number of data points below the given value / total number of data points) × 100

where:

P is the percentile rank expressed as a percentage. The number of data points below the given value is the number of data points in the dataset that are less than the given value.

The total number of data points is the total number of data points in the dataset. Using the given data set, we can calculate the percentile for the data value 111 as follows: There are 6 data points in the dataset that are less than 111.

Therefore, the number of data points below the given value is 6. The total number of data points in the dataset is 16.

Therefore, the total number of data points is 16. The percentile rank of 111 in the dataset is:

P = (number of data points below the given value / total number of data points) × 100P = (6 / 16) × 100P = 37.5.

The percentile for the data value 111 is 13.33%.

The given data set is: 114, 126, 118, 112, 120, 122, 112, 110, 112, 114, 118, 128, 110, 114, 116.

For finding the percentile for the data value 111, firstly, we need to find the rank of this value among the other data values.

To do this, we can sort the data set in ascending order:

110, 110, 112, 112, 112, 114, 114, 116, 118, 118, 120, 122, 126, 128

The data value 111 is not present in the given data set.

Therefore, we can find its rank by taking the average of the ranks of the two data values between which it would lie.

111 would lie between the data values 110 and 112. These two values have ranks 1 and 3 respectively.

Therefore, the rank of 111 would be:

Rank of 111 = (1 + 3)/2

                  = 2

This means that the value 111 is at the 2nd position when the data set is sorted in ascending order.

Now we can use the following formula to find the percentile of the data value 111:

Percentile = (Number of values below the given data value / Total number of values) × 100

We can see that there are 1 + 1 = 2 values below 111. (Two values because the data value 110 is repeated.)

The total number of values in the data set is 15.

Therefore, Percentile = (2/15) × 100

                                    = 13.33%

Therefore, the percentile for the data value 111 is 13.33%.

We can use trigonometry to solve this problem. Let's draw a right triangle to represent the situation:

   h    |  \   9 ft

        |   \

        |    \

        |     \

        -------

        6 ft

Here, h represents the height on the wall where the ladder touches. We want to find the angle of elevation θ.

Using the right triangle, we can write:

sin(θ) = h / 9

cos(θ) = 6 / 9 = 2 / 3

We can solve for h using the Pythagorean theorem:

h^2 + 6^2 = 9^2

h^2 = 9^2 - 6^2

h = √(9^2 - 6^2)

h = √45

h = 3√5

So, sin(θ) = 3√5 / 9 = √5 / 3. We can solve for θ by taking the inverse sine:

θ = sin^-1(√5 / 3)

θ ≈ 37.5 degrees

Therefore, to the nearest tenth of a degree, the angle of elevation the ladder makes with the ground is 37.5 degrees.

Factor by grouping: 16x³ +28x² - 28x - 49 = 0 is  (4x² - 7) (4x - 7) = 0

Large polynomials can be divided into groups based on a common factor. As a result, we may factor each distinct group and then merge like words. We refer to this as factoring by grouping.

We have the equation,

16x³ +28x² - 28x - 49 = 0

In order to solve the equation by using factor by grouping:

We find common terms in between,

So, we arrange the terms,

16x³ +28x² - 28x - 49 = 0

4x² (4x - 7) -7 (4x - 7) = 0

Here, we have common term (4x-7).

If they both were driving at 9 AM, Jean and Sally, based on their average driving speeds, would meet at 14:00 hours or 2:00 P.M.

The average speed is the quotient of the total distance traveled and the time interval.

As a scalar quantity, the average speed is represented by its magnitude.

From the distance, speed, and time formula, we can determine the time when Jeann and Sally will meet.

Time = Distance/Speed

Total distance covered = 445 miles

Jean's average driving speed = 43 mph

Sally's average driving speed = 46 mph

Combined average driving speed = 89 mph

A triangle is a polygon that has three sides, three angles, and three vertices. It is a fundamental shape in geometry and is used in many different areas of mathematics, science, and engineering.

Triangles are classified based on the relative lengths of their sides and the size of their angles. A scalene triangle has no sides of equal length, an isosceles triangle has two sides of equal length, and an equilateral triangle has all three sides of equal length. Triangles can also be classified based on the size of their angles, with acute triangles having all angles less than 90 degrees, obtuse triangles having one angle greater than 90 degrees, and right triangles having one angle equal to 90 degrees.

We can use the Pythagorean theorem to find the length of the other leg of the right triangle. The Pythagorean theorem states that for a right triangle with legs of lengths a and b and hypotenuse of length c, we have:

\(a^2 + b^2 = c^2\)

In this case, we know that one leg has a length of 14 yards and the hypotenuse has a length of 42 yards, so we can write:

\(14^2 + b^2 = 42^2\)

Simplifying and solving for b, we get:

b = sqrt(42² - 14²)

b = sqrt(1680)

b ≈ 40.99 yards (rounded to the nearest hundredth)
