\(Therefore,y = \frac{6}{11} (x - 0) + 0,y = - \frac{6}{11} (x - 0) + 0\)
\(\large\boxed{\bold{y = \frac{6x}{11},y = - \frac{6x}{11} . }}\)
If y²/36 - x²/121 = 1, the asymptotes are y = (36/121) x and y = -(36/121) x.
To find the equations for the asymptotes of the hyperbola represented by the equation y²/36 - x²/121 = 1, we can compare it with the standard form of a hyperbola:
(y - k)² / a² - (x - h)² / b² = 1
where (h, k) represents the center of the hyperbola.
In the given equation, we have y²/36 - x²/121 = 1. To put it in standard form, we need to divide both sides by 1 (which is essentially dividing by 1 on the right side):
y²/36 - x²/121 = 1 / 1
Now, we can see that a² = 36 and b² = 121.
To find the equations of the asymptotes, we use the center (h, k) and the values of a and b. The asymptotes of a hyperbola have equations of the form:
y = k ± (a/b)(x - h)
In this case, the center (h, k) is (0, 0), a² = 36, and b² = 121:
The equations for the asymptotes are:

Put the equation in
slope-intercept form.
y - 4x = 17
y = 4x + [?]
Enter
Answer: To put the equation y - 4x = 17 in slope-intercept form, we need to isolate the y variable on one side of the equation and have the coefficient of x be the slope of the line and the constant term be the y-intercept.
Slope-intercept form is written as y = mx + b, where m is the slope and b is the y-intercept.
Starting with the equation y - 4x = 17, we can isolate y by adding 4x to both sides:
y - 4x + 4x = 17 + 4x
y = 4x + 17
So, the equation in slope-intercept form is y = 4x + 17, where the slope (m) is 4 and the y-intercept (b) is 17.
Step-by-step explanation:
y-4x = 17
slope intercept= y= 4x + 17

Step-by-step explanation:
Which of the following factors does NOT control the stability of a slope?
the angle of repose for intact bedrock
whether the slope is rock or soil
the amount of water in the soil
the orientation of fractures, cleavage, and bedding
The factor that does NOT control the stability of a slope is the angle of repose for intact bedrock. The angle of repose refers to the steepest angle at which a pile of loose material remains stable without sliding. It is mainly applicable to loose materials like soil and granular substances, not intact bedrock.
Bedrock stability depends on factors such as its strength, fracturing, and geological properties, rather than the angle of repose. Factors that control the stability of a slope include whether the slope is rock or soil. Rock slopes tend to be more stable than soil slopes due to the cohesive nature of intact rock.
The amount of water in the soil also affects slope stability, as excessive water can increase pore pressure and reduce the shear strength of the soil, leading to slope failure. Additionally, the orientation of fractures, cleavage, and bedding in the rock can influence slope stability by creating planes of weakness or strength.
To summarize, while the angle of repose is a significant factor in slope stability, it is not applicable to intact bedrock. The stability of a slope is influenced by the type of material (rock or soil), the presence of water, and the orientation of fractures and bedding.

(x, y) =
The function y = x^3 - 12x has a local minimum at x = 2 with a corresponding y-value of -16. There are no local or absolute maxima for this function over the entire range of (-∞, ∞).
The local and absolute minima and maxima of the function y = x^3 - 12x over the entire range (-∞, ∞) are as follows:
Local minimum: There is no local minimum for this function.
Local maximum: There is no local maximum for this function.
Absolute minimum: The absolute minimum occurs at x = 2, where y = -16.
Absolute maximum: There is no absolute maximum for this function.
To determine the local and absolute minima and maxima, we need to find the critical points of the function. These occur where the derivative is equal to zero or does not exist. Taking the derivative of the function, we get y' = 3x^2 - 12. Setting y' = 0 and solving for x, we find x = ±2.
By analyzing the sign of the derivative around these critical points, we can determine the nature of the extrema. However, since we are considering the entire range of (-∞, ∞), there are no local maxima or minima. The function simply increases or decreases without bound.
The absolute minimum occurs at x = 2, where y = -16. However, there is no absolute maximum as the function has no upper bound.
In conclusion, the function y = x^3 - 12x has a local minimum at x = 2 with a corresponding y-value of -16, but no local maximum, absolute minimum, or absolute maximum over the entire range (-∞, ∞).

The most appropriate choice for profit and loss will be given by
Uncle Ben will feed his cows 2 pounds of grain supplement.
What is profit and loss?
If the selling price is more than the cost price, then the difference between the selling price and the cost price will give the profit.
If the selling price is less than the cost price, then the difference between the selling price and the cost price will give the loss.
Here,
For 1 pound
Cost price of grain supplement = \(0.70 \times 1\)
= $\($0.70\)
Selling price of milk = \(0.20 \times 5\)
= $\(1\)
Profit = $(\(1 - 0.70\))
= $0.30
For 2 pounds
Cost price of grain supplement = \(0.70 \times 2\)
= $\($1.40\)
Selling price of milk = \(0.20 \times 9\)
= $\(1.80\)
Profit = $(\(1.80 - 1.40\))
= $0.40
For 3 pounds
Cost price of grain supplement = \(0.70 \times 3\)
= $\($2.10\)
Selling price of milk = \(0.20 \times 12.3\)
= $2.46
Profit = $(\(2.46 - 2.10\))
= $0.36
For 4 pounds
Cost price of grain supplement = \(0.70 \times 4\)

A farmer has 220 bushels of apples for sale at his route stop side stand. He sells an average of 15 1/8 bushels each day represent the total change in number of bushels he has for sale after seven days.
After \(7\) days, there has been a total increase of sale \(116.2\)bushels in his available inventory.
What do the words "sell" and "sell" mean?Sale, which appears in the expressions for sale as well as on sale, refers to a trade at a discounted price. As used as a verb, sell means to provide something in return for money.
Which of the two available meanings?The act or selling products or services is the definition of sale at its most fundamental level. It may also be used to describe a quantity sold or a certain period during which prices are lowered. These explanations are all nouns. Use the word sale in any writing if you're discussing the exchange of products or services for cash in the noun form.
A farmer sells an average of \(15 \frac{1}{8}\) bushels each day.
We write above improper fraction \(15 \frac{1}{8}\) in proper fraction as \(\frac{121}{5}\)
And the decimal form of given fraction 121/5 is:
\(\frac{121}{5} = 24.2\)
After \(7\) days, he would sold \((15 \frac{1}{8} ) * 7\) bushels.
We simplify an expression \((15 \frac{1}{8} ) * 7\)
\((15 \frac{1}{8} ) * 7 = 24.2 * 7\)
\(=169.4\)
As a result, the farmer would have only \(220-169.4 = 50.6\) bushels for sale.
Therefore, the total change in the number of bushels he has for sale after \(7\) days \(= 169.4\)

let c be the point on the line segment ab that is twice as far from b as it is from a. if a − oa l, b − ob l, and c − oc l, show that c − 2 3 a 1 1 3 b.
The vector c = (2/3)a + (1/3)b, where c represents the position vector of point C on the line segment AB.
Let's consider the line segment AB, where point C is located. We can express the position vectors as a = OA, b = OB, and c = OC. According to the given information, C is twice as far from B as it is from A. This implies that the ratio of the distances AC and BC is 1:2.
To prove that c = (2/3)a + (1/3)b, we can use the concept of a linear combination of vectors. Since C is two-thirds of the distance from A, and the remaining one-third of the distance from B, we assign the weights (coefficients) of 2/3 to vector a and 1/3 to vector b. Thus, the position vector of C, c, can be expressed as the sum of these weighted vectors: (2/3)a + (1/3)b.
By distributing the weights and combining the terms, we can simplify the expression: (2/3)a + (1/3)b = (2/3)(OA) + (1/3)(OB) = (2/3)OA + (1/3)OB = OC.
Therefore, we have proven that c = (2/3)a + (1/3)b, confirming that point C lies two-thirds of the way from A and one-third of the way from B on the line segment AB.

Consider a paint-drying situation in which drying time for a test specimen is normally distributed with σ = 9. The hypotheses H0: μ = 74 and Ha: μ < 74 are to be tested using a random sample of n = 25 observations.
If a level 0.01 test is used with n = 100, what is the probability of a type I error when μ = 76? (Round your answer to four decimal places.)
The probability of a Type I error when μ = 76, using a level 0.01 test with n = 100, is approximately 0.0099.
To determine the probability of a Type I error when μ = 76, we need to calculate the probability of rejecting the null hypothesis (H0: μ = 74) when it is actually true.
In this case, we are given that the standard deviation (σ) is 9, the sample size (n) is 100, and the significance level (α) is 0.01.
Since the test is conducted using a level 0.01 significance level, the critical region is determined by the lower tail of the distribution. We reject the null hypothesis if the test statistic falls in the critical region.
Since the sample size is large (n = 100), we can use the normal distribution to approximate the sampling distribution of the sample mean.
The test statistic follows a standard normal distribution under the null hypothesis, with a mean of 74 and a standard deviation of σ/√n = 9/√100 = 0.9.
To find the critical value that corresponds to a significance level of 0.01, we can use a standard normal distribution table or a calculator. The critical value is approximately -2.33.
Now, we can calculate the probability of a Type I error:
P(Type I error) = P(reject H0 | H0 is true)
P(Type I error) = P(sample mean < critical value | μ = 74)
Since μ = 74, the sample mean is normally distributed with a mean of 74 and a standard deviation of 0.9 (σ/√n).
P(Type I error) = P(sample mean < -2.33 | μ = 74)
Using a standard normal distribution table or a calculator, we can find the probability associated with the z-value -2.33, which is approximately 0.0099.
Therefore, the probability of a Type I error when μ = 76, using a level 0.01 test with n = 100, is approximately 0.0099.

The constant of proportionality is found with the following formula.
\(m=\frac{y_2-y_1}{x_2-x_1}\)First, we transform the mixed number 4 1/5 into a fraction.
\(4\frac{1}{5}=\frac{4\cdot5+1}{5}=\frac{20+1}{5}=\frac{21}{5}\)So, we use the following
\(\begin{gathered} x_1=7 \\ x_2=30 \\ y_1=\frac{21}{5} \\ y_2=18 \end{gathered}\)Replacing these values in the formula, we have
\(m=\frac{18-\frac{21}{5}}{30-7}=\frac{\frac{90-21}{5}}{23}=\frac{\frac{69}{5}}{23}=\frac{69}{23\cdot5}=\frac{69}{115}=\frac{3}{5}\)Therefore, the constant of proportionality is 3/5.Draw a sketch of y = x2 - x - 3for values of x in the domain -3 <=x<= 3. Write down the coordinates of the turning point in your solution. Hence, from your sketch, find approximate solutions to:x2 – X – 3 = 0.
The sketch of the function y = \(x^{2}\) - x - 3 for -3 <= x <= 3 reveals a parabolic curve that opens upwards. The turning point of the parabola, also known as the vertex, can be identified as (-0.5, -3.25).
To sketch the graph of y = \(x^{2}\) - x - 3, we consider the given domain of -3 <= x <= 3. The function represents a parabola that opens upwards. By calculating the coordinates of the turning point, we can locate the vertex of the parabola.
To find the x-coordinate of the turning point, we use the formula x = -b/2a, where a and b are the coefficients of the quadratic equation. In this case, a = 1 and b = -1. Substituting these values, we have x = -(-1)/2(1) = -0.5.
To find the y-coordinate of the turning point, we substitute the x-coordinate (-0.5) into the equation y = \(x^{2}\) - x - 3. Evaluating this expression, we get y = \(-0.5^{2}\) - (-0.5) - 3 = -3.25.
Therefore, the turning point of the parabola is approximately (-0.5, -3.25).
From the sketch, we can estimate the approximate solutions to the equation \(x^{2}\)- x - 3 = 0 by identifying the x-values where the graph intersects the x-axis. These solutions are approximately x ≈ -2.5 and x ≈ 1.5.

N = 10, k = 4, n = 2.
The probability that both are green is P(X = 2), hence:
\(P(X = x) = h(x,N,n,k) = \frac{C_{k,x}C_{N-k,n-x}}{C_{N,n}}\)
\(P(X = 2) = h(2,10,2,4) = \frac{C_{4,2}C_{6,0}}{C_{10,2}} = 0.1333\)
0.1333 = 13.33% probability that two of the socks will both be green if the socks are drawn without replacement.
