Using the triangle inequality theorem, the largest possible whole-number length for the third side is 4.

The third side of a triangle must be shorter than the sum of the other two sides and longer than the difference between the other two sides.

So, for a triangle with sides of length 1, 4, and x (where x is the length of the third side), we have:

1 + 4 > x

4 + x > 1

1 + x > 4

Simplifying these inequalities, we get:

5 > x

x > 3

x > -3 (this inequality is always true)

The largest possible whole-number length for the third side is 4, since it is the largest integer that satisfies the above inequalities.

SOLUTION:

Step 1:

In this question, we are given the following:

The volume of a gas V held at a constant temperature in a closed container varies inversely with its pressure P. If the volume of a gas is 800 cubic centimeters when the pressure is 450 millimeters of mercury​ (mm Hg), find the volume when the pressure is 200 mm Hg.

Step 2:

This is an application of Boyle's law which states that:

Boyle’s law is a gas law that states that the pressure exerted by a gas (of a given mass, kept at a constant temperature) is inversely proportional to the volume occupied by it. In other words, the pressure and volume of a gas are inversely proportional to each other as long as the temperature and the quantity of gas are kept constant.

Next:

CONCLUSION:

The volume when the pressure is 200 mm Hg is:

Each transformation affects the shape and position of the graph. It is important to carefully consider the order of the transformations and their impact on the equation.

1. Horizontal Shift (c):
If there is a horizontal shift, the equation becomes y = (x - c)^3.
For example, if there is a shift of 2 units to the right, the equation would be y = (x - 2)^3.

2. Vertical Shift (d):
If there is a vertical shift, the equation becomes y = x^3 + d.
For example, if there is a shift of 3 units upwards, the equation would be y = x^3 + 3.

3. Vertical Stretch (a):
If there is a vertical stretch or compression, the equation becomes y = a * x^3.
For example, if there is a vertical stretch by a factor of 2, the equation would be y = 2 * x^3.

4. Reflection (along the x-axis):
If there is a reflection along the x-axis, the equation becomes y = -x^3.
This flips the graph of the original function upside down.

5. Reflection (along the y-axis):
If there is a reflection along the y-axis, the equation becomes y = (-x)^3.
This mirrors the graph of the original function.

6. Combined Transformations:
If there are multiple transformations, we can apply them in the order they are given. For example, if there is a vertical stretch by a factor of 2 and a horizontal shift of 3 units to the right, the equation would be y = 2 * (x - 3)^3.

Remember, each transformation affects the shape and position of the graph. It is important to carefully consider the order of the transformations and their impact on the equation.

We can simplify \((16x^4)^(-1/2) to 1/(4x^2)\) using the properties of rational exponents.

Certainly! Here's an example:

Simplify the expression: \((16x^4)^(-1/2)\)

We can apply the property of rational exponents which states that \((a^m)^n = a^(m*n)\). Using this property, we get:

\((16x^4)^(-1/2) = 16^(-1/2) * (x^4)^(-1/2)\)

Next, we can simplify \(16^(-1/2)\) using the rule that \(a^(-n) = 1/a^n\):

\(16^(-1/2) = 1/16^(1/2) = 1/4\)

Similarly, we can simplify \((x^4)^(-1/2)\) using the rule that \((a^m)^n = a^(m*n)\):

\((x^4)^(-1/2) = x^(4*(-1/2)) = x^(-2)\)

Substituting these simplifications back into the original expression, we get:

\((16x^4)^(-1/2) = 1/4 * x^(-2) = 1/(4x^2)\)

Therefore, the simplified expression is \(1/(4x^2).\)

The given series is divergent.

We can use the limit comparison test to determine the convergence or divergence of the given series:

First, note that for all n ≥ 1, we have: \(\frac{(n^9 + 1) }{ (n^10 + 1)}\) ≤ \(\frac{n^9 }{n^10} = \frac{1}{n}\)

Therefore, we can compare the given series to the harmonic series ∑ 1/n, which is a well-known divergent series. Specifically, we can apply the limit comparison test with the general term \(a_n = \frac{(n^9 + 1)}{(n^{10} + 1)}\) and the corresponding term \(b_n = \frac{1}{n}\):

lim (n → ∞) \(\frac{a_n }{ b_n}\) = lim (n → ∞) \(\frac{\frac{(n^9 + 1)}{(n^10 + 1)} }{\frac{1}{n} }\)

= lim (n → ∞) \(\frac{ n^{10} }{ (n^9 + 1)}\)

= lim (n → ∞) \(\frac{n}{1+\frac{1}{n^{9} } }\)

= ∞

Since the limit is positive and finite, the series ∑ \(\frac{(n^9 + 1) }{ (n^10 + 1) }\) behaves in the same way as the harmonic series, which is divergent. Therefore, the given series is also divergent.

The relationship that is represented by the graph, between number of rose plants and the number of roses is: proportional.

If a graph represents a proportional relationship, it passes through the origin (0, 0) and has a constant of proportionality that is expressed as k = y/x.

Thus, to determine whether the graph that has a line that passes through points (1, 5), (2, 10), (3, 15), (4, 20) represents a proportional relationship, use the coordinates of the points to find out if k = y/x is the same for all ordered pairs of each point. If it is the same, then it represents the constant of proportionality, meaning the relationship is proportional.

Thus:

For (1, 5), k = 5/1 = 5

For (2, 10), k = 10/2 = 5

For (3, 15), k = 15/3 = 5

For (4, 20), k = 20/4 = 5

This means that, the relationship that is represented by the graph, between number of rose plants and the number of roses is: proportional.

Therefore, the sum of the first 1234 terms of this sequence is 1234.

To find the sum of the first 1234 terms of the sequence consisting of 1's separated by blocks of 2's with n 2's in the nth block, we need to determine the number of blocks and the number of 1's in each block.

Let's examine the pattern of the sequence:

Block 1: 2's

= 1's

= 1 (1 2)

Block 2: 2's

= 2's

= 22 (1 22 1)

Block 3: 2's

= 3's

= 222 (1 222 1)

Block 4: 2's

= 4's

= 2222 (1 2222 1)

...

We observe that the number of 2's in each block is equal to the number of the block itself. So, in the nth block, there are n 2's.

Now, let's calculate the number of blocks required to reach the 1234th term:

To find the number of blocks, we need to determine the maximum block number before the 1234th term. We can calculate this by finding the sum of the series 1 + 2 + 3 + ... + n until the sum is greater than or equal to 1234.

The formula for the sum of the series 1 + 2 + 3 + ... + n is given by: S = (n/2)(n+1).

Let's solve this equation:

(n/2)(n+1) = 1234

\(n^2 + n - 2468 = 0\)

Using the quadratic formula:

n = (-1 + √(1 + 4*2468)) / 2

n ≈ 61.76

Since n must be a whole number, we take the ceiling of n, which gives us 62.

Therefore, there are 62 blocks in the sequence.

Next, let's calculate the number of 1's in each block:

In the nth block, there are n 2's. Since each 2 is separated by a 1, there are n + 1 terms in each block.

So, the number of 1's in each block is (n + 1) - n = 1.

Since there is always one 1 between two consecutive blocks, the total number of 1's in the sequence is equal to the number of blocks, which is 62.

Finally, let's calculate the sum of the first 1234 terms:

Each block has n + 1 terms, which gives us (n + 1) + (n + 1) + ... + (n + 1) (62 times).

Sum of (n + 1) repeated 62 times = 62(n + 1)

= 62 * 2

= 124.

In addition to the blocks, we have 1234 - 62 = 1172 remaining terms, which are all 1's.

So, the sum of the first 1234 terms is 62 + 1172 = 1234.

The value of Kb will be  1.83 × 10⁻¹¹.

The given problem states that Ka is equal to 5.47×10⁻⁴, and the task is to find Kb. Ka and Kb are related to each other through the equation Kw = Ka × Kb. Kw represents the ion product of water, which is equal to the concentration of H₃O⁺ ions multiplied by the concentration of OH⁻ ions. It has a value of 1.0 × 10⁻¹⁴.

Using the fact that pKw = pH + pOH = 14.00, we can determine the relationship between pKa and pKb. By rearranging the equation, we get pKa + pKb = 14.00. This equation relates the logarithms of the acid dissociation constant (pKa) and the base dissociation constant (pKb).

To find Kb, we can use the formula Kb = Kw/Ka. Substituting the given values, we have Kb = (1.0 × 10⁻¹⁴)/(5.47 × 10⁻⁴). Simplifying this expression, we find Kb = 1.83 × 10⁻¹¹.

Therefore, the value of Kb is determined to be 1.83 × 10⁻¹¹.

The maximal value of the sample covariance is \(sx*sy\), which represents the highest correlation possible between X and Y.

The formula for the sample covariance between X and Y is given by \(cov(X,Y) = (1/(n-1)) Σ (xi - xmean)(yi - ymean)\). The maximal value for the sample covariance is equal to the product of the standard deviations of X and Y, which can be calculated using the formula \(sx*sy = (1/(n-1)) Σ (xi - xmean)^2 * (1/(n-1)) Σ (yi - ymean)^2\). Using the Cauchy-Schwarz Inequality, we can know that \(cov(X,Y) < = sx*sy\).

The solution to the equation is y₂ = -13.51.

To find the exact value of y₂ without rounding, we will use the method of corner points. This method involves finding the corner points of the feasible region and evaluating the objective function at each corner point to determine the optimal solution.

Step 1: Setting up the inequalities:

Let's rewrite the constraints with variables in terms of a fraction:

Constraint 1: 5y₁ + 9y₂ + 4y₃ < 15 ... (1)

Constraint 2: 5y₁ + 18y₂ + 2y₃ > 8 ... (2)

Step 2: Solving for y₂:

To solve for y₂, we will express y₂ in terms of the other variables in the constraints.

From constraint (1), we have:

5y₁ + 9y₂ + 4y₃ < 15

9y₂ < 15 - 5y₁ - 4y₃

y₂ < (15 - 5y₁ - 4y₃)/9

From constraint (2), we have:

5y₁ + 18y₂ + 2y₃ > 8

18y₂ > 8 - 5y₁ - 2y₃

y₂ > (8 - 5y₁ - 2y₃)/18

Step 3: Analyzing the constraints:

Now we have the inequalities for y₂ in terms of y₁, y₃, and constants. Let's examine the conditions to satisfy the constraints:

y₂ > (8 - 5y₁ - 2y₃)/18 ... (3)

y₂ < (15 - 5y₁ - 4y₃)/9 ... (4)

Considering the constraints y₁ > 0, y₃ > 0, and y₂ > 0, we need to find the range of values for y₁ and y₃ that satisfy these inequalities.

Analyzing the inequalities:

Let's examine the intervals for y₁ and y₃ that satisfy the constraints:

From inequality (3):

y₂ > (8 - 5y₁ - 2y₃)/18

For y₁ > 0 and y₃ > 0, the numerator 8 - 5y₁ - 2y₃ should be positive to maintain y₂ > 0.

Simplifying the numerator:

8 - 5y₁ - 2y₃ > 0

8 > 5y₁ + 2y₃

This implies that 5y₁ + 2y₃ < 8.

From inequality (4):

y₂ < (15 - 5y₁ - 4y₃)/9

For y₁ > 0 and y₃ > 0, the numerator 15 - 5y₁ - 4y₃ should be positive to maintain y₂ > 0.

Simplifying the numerator:

15 - 5y₁ - 4y₃ > 0

15 > 5y₁ + 4y₃

This implies that 5y₁ + 4y₃ < 15.

Step 5: Finding the corner points:

To find the corner points, we need to determine the intersection of the lines 5y₁ + 2y₃ = 8 and 5y₁ + 4y₃ = 15.

Solving the system of equations:

5y₁ + 2y₃ = 8 ... (5)

5y₁ + 4y₃ = 15 ... (6)

Multiplying equation (5) by 2, we get:

10y₁ + 4y₃ = 16 ... (7)

Subtracting equation (6) from equation (7):

(10y₁ + 4y₃) - (5y₁ + 4y₃) = 16 - 15

5y₁ = 1

Dividing both sides by 5:

y₁ = 1/5

Substituting y₁ = 1/5 into equation (5):

5(1/5) + 2y₃ = 8

1 + 2y₃ = 8

2y₃ = 8 - 1

2y₃ = 7

y₃ = 7/2

Therefore, one corner point is (y₁, y₂, y₃) = (1/5, ?, 7/2).

Step 6: Evaluating the objective function:

Now, let's evaluate the objective function at the corner point (1/5, ?, 7/2) to find the value of y₂.

Substituting the corner point into the objective function:

w = 35y₁ + 72y₂ + 65y₃

w = 35(1/5) + 72y₂ + 65(7/2)

w = 7 + 72y₂ + 2275/2

w = 7 + 72y₂ + 1137.5

w = 1144.5 + 72y₂

172 = 1144.5 + 72y₂

Let's start by subtracting 1144.5 from both sides of the equation:

172 - 1144.5 = 1144.5 + 72y₂ - 1144.5

This simplifies to:

-972.5 = 72y₂

To isolate y₂, we can divide both sides of the equation by 72:

-972.5 / 72 = 72y₂ / 72
