Use the equations to find
∂z/∂x and ∂z/∂y.
x2 + 8y2 + 7z2 = 1

Answers

Answer 1

To find x2 + 8y2 + 7z2 = 1 using equations, we need to use partial differentiation with respect to x (represented by ∂x) and z (represented by ∂z). We start by taking the partial derivative of the given equation with respect to x, which gives us: 2x + 0 + 0 = 0

Simplifying this, we get:

x = 0

Next, we take the partial derivative of the given equation with respect to z, which gives us:

0 + 0 + 14z = 0

Simplifying this, we get:

z = 0

Now, substituting x and z in the given equation, we get:

8y2 = 1

Solving for y, we get:

y = ±√(1/8)

Therefore, the equation x2 + 8y2 + 7z2 = 1 can be represented as x = 0, y = ±√(1/8), and z = 0.
To solve the equation x^2 + 8y^2 + 7z^2 = 1, follow these steps:

1. Identify the terms: In this equation, x, y, and z are variables, and 1 is a constant. You want to find the values of x, y, and z that satisfy the equation.

2. Rewrite the equation: You can rewrite the equation as ∂z/∂x = - (x^2 + 8y^2 - 1) / 7z^2. This equation helps us see how z changes with respect to x.

3. Observe constraints: The given equation represents an ellipsoid in 3D space. As x, y, and z vary, they are constrained by the equation.

4. Find solutions: Solving the equation involves finding values of x, y, and z that satisfy the equation. You can solve this by using substitution, elimination, or graphing methods.

Keep in mind that there might be multiple solutions depending on the context or constraints given.

Answer:

∠S = 105°

Step-by-step explanation:

Cyclic quadrilateral:

   Quadrilateral MNST is a cyclic quadrilateral. In cyclic quadrilateral, the opposite angles are supplementary.

     m∠S + m∠M = 180°

 3x + 2x +  5 = 180

        5x  + 5  = 180           {Combine like terms}

                 5x = 180 - 5     {Subtract 5 from both sides}

                 5x = 175

                    x = 175 ÷ 5  {Divide both sides by 5}

∠S = 3x

Two ocean beaches are being affected by erosion. The table shows the width, in feet, of each beach measured at high tide where 1995 is represented by year 0:

0 100 20

10 80 70
11 78 75
12 76 80
15 70 95

Describe the patterns shown by the erosion data measurements shown for each of the beaches in the table.
Between which years will the beaches have approximately the same width?
Assuming these rates remain constant, what can you do to get a better approximation of when the two beaches will have the same width?

Answers

The pattern shown by the erosion data measurements for the Western Beach is that the width decreases over time, with a steady decrease of about 10 feet per year. The pattern for the Dunes Beach is that the width increases over time, with an increase of about 5 feet per year.

Based on the data, it appears that the beaches will have approximately the same width around year 20. At this point, the Western Beach will have a width of approximately 50 feet and the Dunes Beach will have a width of approximately 90 feet.

To get a better approximation of when the two beaches will have the same width, it would be necessary to gather more data points over a longer period of time and to take into account other factors that may affect the beaches' widths such as the strength of the waves, the composition of the beach, and human interventions that may be taking place.

What is m∠GPE?
m∠GPE =

Answers

The angle when the secant intersect is as follows:

m ∠GPE = 29 degrees

How to find the angles formed by intersecting secant?

A secant is a line that intersects a circle in exactly two points.

If two secants or chords intersect in the interior of a circle, then the measure of each angle formed is half the sum of the measures of its intercepted arcs.

Therefore,

m ∠GPE = 1 / 2 ( mGE -  mHF)

mGE = 99°

mHF = 41°

m ∠GPE = 1 / 2 (99 - 41)

m ∠GPE = 1 / 2 (58)

Therefore,

How do you find the pattern rule of a sequence?

Answers

An example of a pattern rule is "add 3" which means that to find the next term in a sequence, you add 3 to the previous term.

To write a rule for a sequence, you need to identify the pattern. This involves looking at the differences between the numbers and seeing if there is a pattern of increasing or decreasing numbers. Once you have identified the pattern, you can then write a rule that expresses that pattern.

Examples of pattern sequences include the Fibonacci sequence (1,1,2,3,5,8,13,21,34, etc.), the even numbers (2,4,6,8,10, etc.), and the multiples of 3 (3,6,9,12,15, etc.).

To describe the pattern of a sequence, you need to look at the differences between the numbers and the pattern of increases or decreases. For example, in the Fibonacci sequence, the pattern is that each number is the sum of the two numbers before it so 1+1=2, 1+2=3, 2+3=5, etc.

What is a pattern?

A pattern is a repeated arrangement of numbers, shapes, colours, or other elements. The Pattern can be associated with any kind of event or object. A pattern is defined as a set of numbers that are related to one another in a specific way. Patterns are sometimes referred to as sequences.

Given that:

Chamber 7: 1.207 cm³

Chamber 6: 1.135 cm³

Chamber 5: 1.068 cm³

Chamber 4: 1.005 cm³

Chamber 3: 0.945 cm³

Chamber 2: 0.889 cm³

Chamber 2: 0.836 cm³

First difference:        .072        0.067    0.063   0.060    0.056      0.053

Second difference:            0.005     0.004    0.003     0.004    0.003

Since the difference is not the same, thus the volume is not in a linear pattern. Then find the ratio consecutive volume:

1.207/1.135 ≈ 1.063

1.135/1.068 ≈ 1.063

1.068/1.005 ≈ 1.063

1.005/0.945 ≈ 1.063

Marsha and Kristen are scuba diving. Marsha is at an elevation of -24 feet, and she is descending at a rate of 12 feet per minute. Kristen is at an elevation of -8 feet and she is descending at a rate of 16 feet each minute. The variable t represents the time in minutes.After how many minutes will Marsha and Kristen be at the same elevation? At what elevation will they be at that time?

Answers

Marsha and Kristen will be at the same elevation of -72 feet after 4 minutes.

How to find their elevation?

To find out after how many minutes Marsha and Kristen will be at the same elevation, we can set their elevation equations equal to each other:

-24 - 12t = -8 - 16t

Then, we can solve for t by adding 8 to both sides and dividing by 4:

t = 4

So, Marsha and Kristen will be at the same elevation after 4 minutes.

To find out what elevation they will be at that time, we can substitute 4 into either one of the elevation equations and solve for the elevation:

-24 - 12(4) = -24 - 48 = -72

So, Marsha and Kristen will be at the same elevation of -72 feet after 4 minutes.

Set up this equation and solve for the potential possibilities of x to find these numbers: x(x-3)=0

Divide both sides by (x-3) to find one of the values:

x(x-3)/(x-3)=0(x-3)

Because (x-3) cancels on the left side of the equation and everything divided by 0 is zero on the right, you should get: x=0.

Now that you've determined one of the excluded values, work out the other:

To begin, split both sides by x:

x(x-3)=0

x-3=0

Finally, multiply both sides by -3 to get: x=3
