Consider the case in which the proportionality constant C is equal to 1/2. Plot the graph of y=1/2x. How would you graph?
Answers
To graph the equation y = (1/2)x, we can plot points on a coordinate plane and connect them to create a straight line. Here's how to do it:
1. Choose some x-values to evaluate the equation. Let's select a range of x-values, such as -10, -5, 0, 5, and 10.
2. Substitute each x-value into the equation to find the corresponding y-values. For example:
- For x = -10, y = (1/2)(-10) = -5
- For x = -5, y = (1/2)(-5) = -2.5
- For x = 0, y = (1/2)(0) = 0
- For x = 5, y = (1/2)(5) = 2.5
- For x = 10, y = (1/2)(10) = 5
3. Plot the points (x, y) on a graph. In this case, the points would be:
(-10, -5), (-5, -2.5), (0, 0), (5, 2.5), (10, 5)
4. Connect the plotted points with a straight line. The line should pass through all the points.
The resulting graph is a straight line with a slope of 1/2, passing through the origin (0, 0), and extending infinitely in both directions.

. (5 pts) Find the arc length of the curve r = 2 cos 0,0 ≤ 0< value. 2 dr S= S²√ (16) ² a p² + do Give the exact
Answers
The exact arc length of the curve r = 2cosθ, where 0 ≤ θ < 2π, is 4π units.
To find the arc length of the curve represented by the polar equation r = 2cosθ, where 0 ≤ θ < 2π, we can use the arc length formula for polar curves:
S = ∫[θ1 to θ2] √(r^2 + (dr/dθ)^2) dθ.
In this case, r = 2cosθ and dr/dθ = -2sinθ. Let's calculate the arc length:
S = ∫[θ1 to θ2] √(r^2 + (dr/dθ)^2) dθ
= ∫[θ1 to θ2] √((2cosθ)^2 + (-2sinθ)^2) dθ
= ∫[θ1 to θ2] √(4cos^2θ + 4sin^2θ) dθ
= ∫[θ1 to θ2] √(4(cos^2θ + sin^2θ)) dθ
= ∫[θ1 to θ2] √(4) dθ
= ∫[θ1 to θ2] 2 dθ
= 2 ∫[θ1 to θ2] dθ
= 2(θ2 - θ1).
The arc length S is equal to 2 times the difference between the two angles θ2 and θ1.
Since the given range is 0 ≤ θ < 2π, we have θ1 = 0 and θ2 = 2π.
S = 2(2π - 0)
= 4π.
Therefore, the exact arc length of the curve r = 2cosθ, where 0 ≤ θ < 2π, is 4π units.

Given that y = sin (x) is a solution of y^(4) + 2y"' + 11y" +2y' + 10y = 0 Find the general solution without the use of a calculator or a computer.
Answers
The required general solution for the given equation is
y(x) = \(e^{(-x/2)(C1 sin(\sqrt{(7/2)x} )}\) + C2 cos(√(7/2)x)) + \(e^{(-x/2)(C3 sin(\sqrt{(21/2)x }\)+ C4 cos(√(21/2)x))
here
C1, C2, C3 and C4 = constants determined by initial conditions.
It is given to us
y = sin(x) is a solution of y⁴ + 2y"' + 11y" +2y' + 10y = 0, by the method of undetermined coefficient we can calculate the general solution.
we evaluate the differential equation by considering that
y = \(e\sqrt{(rx)}\). We get r⁴ + 2r³ + 11r² + 2r + 10 = 0.
After factorizing the equation as
(r² + r + 2)(r² + r + 5) = 0.
The evaluated roots of this equation are
r = -1/2 ± i√(7/2) and r = -1/2 ± i√(21/2).
We know that sin(x) is a solution of the differential equation,
Therefore, y = A sin(x) + B cos(x) is also a solution.
Now implementing the roots that we have derived, the general solution is
y(x) = \(e ^{(-x/2)(C1 sin(\sqrt{(7/2)x\)+ C2 cos(√(7/2)x)) + \(e ^{(-x/2)(C3 sin\sqrt{((21/2)x)} }\)+ C4 cos(√(21/2)x))
The required general solution for the given equation is
y(x) = \(e^{(-x/2)(C1 sin(\sqrt{(7/2)x} )}\) + C2 cos(√(7/2)x)) + \(e^{(-x/2)(C3 sin(\sqrt{(21/2)x }\)+ C4 cos(√(21/2)x))

Find MN such that LN = 5.7.
Answers
Line LN is compounded by segments LM and MN. The lenght of segment LM is fixed (1.3), and we need to find how long should segment MN be so the whole segment LN has a length of 5.7.
The length of segment LN is the sum of lengths of segments LM and MN. Writing it as an equation:
\(LN=LM+MN\)We an replace the values we know in the equation:
\(5.7=1.3+MN\)Now, we just need to solve for MN:
\(\begin{gathered} MN=5.7-1.3 \\ \\ MN=4.4 \end{gathered}\)Segment MN should have a length of 4.4 for the segment LN to be 5.7. Correct answer is option D.

"If the true proportion of registered Democrats at a large state university is 30 percent, a given random sample is likely to be somewhat close to 30 percent. How likely and how close can both be calculated from the size of the sample"
In other words, the smaller the group, the greater the variance (+/-30%) we should expect from the 30% Democrats statistic. The larger the group, the lower the variance. Considering our attendance experiment and looking at the chart on page 374, if we're sampling a group of 10 students, we can expect an error margin of +/- 30%, but if we’re looking at a group of 50 students, the error margin decreases to +/- 14%. Applying this to our experiment, can we be confident in the results we obtain from each group/category, especially if our class is only, say, 30 students total?
Answers
As the sample size is smaller, the error margin is expected to be higher. This means that the results may not accurately represent the true proportion of Democrats at the university.
If the true proportion of registered Democrats at a large state university is 30 percent, a given random sample is likely to be somewhat close to 30 percent. The smaller the sample size, the greater the variance we should expect from the 30 percent Democrats statistic. This is because small samples can be highly influenced by chance and random variation.
On the other hand, larger samples tend to be more representative of the population, and therefore, have lower variance. Therefore, if we're sampling a group of 10 students, we can expect an error margin of +/- 30%, but if we’re looking at a group of 50 students, the error margin decreases to +/- 14%.
Applying this to the experiment, it can be inferred that the results obtained from each group/category may not be reliable because the class has only 30 students in total.

A set of average city temperatures in May are normally distributed with a mean of 20.66 degrees and a standard deviation of 2 degrees. The average temperature of Singapore is 26 degrees
Answers
Answer:
0.9962
Step-by-step explanation:
The objective of this question is to determine the proportion of average city temperature that is lower than that of Singapore.
Suppose X is a random variable that follows a normal distribution:
Then;
\(X \sim N ( \mu = 20.66, \sigma = 2)\)
\(P(X< 26) = P \bigg ( Z < \dfrac{26 - 20.66}{2} \bigg)\)
\(P(X< 26) = P \bigg ( Z < \dfrac{5.34}{2} \bigg)\)
\(P(X< 26) = P \bigg ( Z < 2.67\bigg)\)
From the z tables;
P(X< 26) = 0.9962
Thus, there is 0.9962 proportion of average city temperature are lower than that of Singapore.
Answer:
0.9962
Step-by-step explanation:
A set of average city temperatures in May are normally distributed with a mean of 20.66 degrees and a standard deviation of 2 degrees. The average temperature of Singapore is 26 degrees
What proportion of average city temperatures are lower than that of Singapore?
Solution:
The z score shows the number of standard deviations by which the raw score is above or below the mean. If the raw score is above the mean then the z score is positive but if the raw score is less than the mean then the raw score is negative. The z score is given by:
\(z=\frac{x-\mu}{\sigma}\\\\where\ x=raw\ score, \mu=mean,\sigma=standard\ deviation\)
Given that μ = 20.66, σ = $2
For the average temperature of Singapore of 26°, the z score is:
\(z=\frac{x-\mu}{\sigma}=\frac{26-20.66}{2} =2.67\)
From the normal distribution table, P(x < 26) = P(z < 2.67) = 0.9962

Given the Square JKLM, if the area of JKLM is 64 sq in.., what is the length of the diagonal KM?
Answers
The length of diagonal KM of square is 11.31 inch.
What is square?
A square is a regular quadrilateral in Euclidean geometry, which means that it has four equal sides and four equal angles. It can also be explained as a rectangle with two adjacent sides that are of equal length.
A square has four equal sides, four vertices, and is a closed, two-dimensional shape. It has parallel sides on either side. A square is also equivalent to a rectangle with equal length and width.
Given:
The Square JKLM, the area of JKLM is 64 sq in.
We have to find the length of diagonal KM.
Since,
Area of square = (side)^2
64 = (side)^2
Side = 8
Length of each side of square is 8 in.
By using the Pythagorean theorem,
(KL)^2 + (LM)^2 = (KM)^2
8^2 + 8^2 = (KM)^2
64 + 64 = (KM)^2
128 = (KM)^2
KM = 11.31
Hence, the length of diagonal KM of square is 11.31 inch.

forces
Answers
The power of substitutes is one of the five forces in Porter's Five Forces framework and it is a measure of how easy it is for customers to switch to alternative products or services. The higher the power of substitutes, the more competitive the industry and the lower the profitability.
The power of substitutes is based on the premise that when there are readily available alternatives to a product or service, customers can easily switch to those alternatives if they offer better value or meet their needs more effectively. This poses a threat to the industry as it reduces customer loyalty and puts pressure on pricing and differentiation strategies.
The availability and quality of substitutes influence the degree to which customers are likely to switch. If substitutes are abundant and offer comparable or superior features, the power of substitutes is strong, increasing the competitive intensity within the industry. On the other hand, if substitutes are limited or inferior, the power of substitutes is weak, providing more stability and protection to the industry.
