Find the value of x in the triangle at the right.
Answers
Answer:
x= 72
Step-by-step explanation:
x° +x° +36°= 180° (∠ sum of △)
2x° +36°= 180° (simplify)
2x°= 180° -36°
2x°= 144°
x°= 144° ÷2 (÷2 on both sides)

O A. Since f has the same limit along two different paths to (0,0), it cannot be determined whether or not f has a limit as (x,y) approaches (0,0).
Does the function f(x, y) = x^4 + y have a limit as (x, y) approaches (0, 0) along different paths?Let's consider the different paths of approach to the point (0,0) and evaluate the function f(x,y) = x⁴ + y.
Along y = kx, x ≠ 0
Substituting y = kx into the function, we get f(x, y) = x⁴ + kx.As (x,y) approaches (0,0) along this path, we have x → 0 and y → 0.Therefore, the limit of f(x,y) as (x,y) approaches (0,0) along this path is:lim(x,y)→(0,0) f(x,y) = lim(x→0) (x⁴ + kx) = 0⁴ + k(0) = 0.Along y = kx³ , x ≠ 0
Substituting y = kx^3 into the function, we get f(x, y) = x⁴ + kx³ .As (x,y) approaches (0,0) along this path, we have x → 0 and y → 0.Therefore, the limit of f(x,y) as (x,y) approaches (0,0) along this path is:lim(x,y)→(0,0) f(x,y) = lim(x→0) (x⁴ + kx³ ) = 0⁴ + k(0) = 0.Considering the above calculations, we can conclude that along both paths, the limit of f(x,y) as (x,y) approaches (0,0) is 0.
Hence, the correct answer is: O A. Since f has the same limit along two different paths to (0,0), it cannot be determined whether or not f has a limit as (x,y) approaches (0,0).

Density is the concept that if you weigh two identically sized cubes made of different materials, they often won't weigh the same. It also implies that a massive cube of Styrofoam can have a weight equal to that of a tiny cube of lead. Iron, lead, or platinum are a few examples of dense materials.The ratio of an object's mass to its volume is its density.The amount of "stuff" that is contained in a certain amount of space is measured by density. For instance, a block of gold will be denser than a chunk of the softer, lighter element lead (Pb), which is a heavier element (Au). A brick is more dense than a block of Styrofoam. It is described as mass divided by volume.density = mass/volume

2. What is the monthly mortgage payment if the beginning principal balance is $ 100,000 , the annual interest rate is 5 % , the loan term is 30 years, and the loan is fully amortizing?
Answers
The monthly mortgage payment for a $100,000 loan with a 5% annual interest rate and a 30-year fully amortizing term is approximately $536.82.
To calculate the monthly mortgage payment, we can use the formula for calculating the fixed monthly payment for a fully amortizing loan. The formula is: M = P * (r * (1 + r)^n) / ((1 + r)^n - 1)
Where:
M = Monthly mortgage payment
P = Principal balance
r = Monthly interest rate (annual interest rate divided by 12 and converted to a decimal)
n = Total number of monthly payments (loan term multiplied by 12)
Plugging in the given values into the formula:
P = $100,000
r = 0.05/12 (5% annual interest rate divided by 12 months)
n = 30 years * 12 (loan term converted to months)
M = 100,000 * (0.004166667 * (1 + 0.004166667)^(3012)) / ((1 + 0.004166667)^(3012) - 1)
M ≈ $536.82
Therefore, the monthly mortgage payment for a $100,000 loan with a 5% annual interest rate and a 30-year fully amortizing term is approximately $536.82.

Adil wants to have a cubical yank in his new house. He wants to store 729m³ water in it. Calculate the minimum height width and length required to build the tank
Answers
By calculating the cube root of 729, we find that x = 9. Therefore, the minimum height, width, and length required to build the tank are all 9m.
To calculate the minimum height, width, and length required to build the tank, we need to consider the volume of the tank. In this case, the volume of the tank is given as 729m³.
Since the tank is cubical, all sides are equal in length. Let's assume the length of each side is 'x'. Therefore, the volume of the tank can be calculated using the formula:
Volume = length × width × height
In this case, since all sides are equal, we can rewrite the formula as:
Volume = x × x × x
Given that the volume is 729m³, we can substitute this value into the formula:
729 = x × x × x
To solve for 'x', we need to find the cube root of 729. The cube root of a number is the value that, when multiplied by itself three times, gives the original number.
By calculating the cube root of 729, we find that x = 9.
Therefore, the minimum height, width, and length required to build the tank are all 9m.

a person who does not ignore a sunk cost increases the probability that
Answers
A person who does not ignore a sunk cost increases the probability of making irrational decisions. This is because they are more likely to continue investing time, money, or effort into a project or situation that is not yielding positive results.
When we refer to a "sunk cost," we mean a cost that has already been incurred and cannot be recovered. Ignoring a sunk cost means not taking it into consideration when making decisions about the future. By not ignoring a sunk cost, individuals may feel a psychological attachment to their past investment, leading them to continue investing in something that may not be beneficial.
This can result in irrational decision-making and potentially wasting additional resources. For example, imagine a person who has spent a significant amount of money on a gym membership but rarely goes to the gym. Instead of accepting the fact that the money is already spent and may not be recouped.
They may feel compelled to continue paying for the membership in the hopes of eventually utilizing it. This decision is influenced by their failure to ignore the sunk cost and assess the situation rationally.

what is the probability of a 20-year flood occurring next year?
Answers
The probability of a 20-year flood occurring next year is approximately 5%.
In probability analysis, a "20-year flood" refers to a flood event that has a 1 in 20 chance of occurring in any given year.
This probability is often expressed as a percentage, which in this case is approximately 5%. The term "20-year flood" is derived from the assumption that, on average, such a flood will occur once every 20 years.
To determine the probability of a 20-year flood occurring in a specific year, we rely on historical data and statistical analysis.
Hydrologists and engineers study past flood events, gathering data on their frequency and magnitude. This information is used to develop flood frequency curves, which show the probability of different flood magnitudes occurring within a given time frame.
The probability of a 20-year flood occurring next year is calculated based on these flood frequency curves. It represents the likelihood of a flood event reaching or exceeding the magnitude associated with a 20-year return period within the next year.
While the probability is estimated, it is important to note that it is not a guarantee. Flood events are influenced by various factors, including weather patterns, land use changes, and local conditions, which can introduce uncertainties into the predictions.

Answers
The joint distribution of \(X\) and \(Y\), I can help you find their marginal distributions and compute the joint probability.
Without knowing the specific joint distribution of \($X$\) and \($Y$\), it is not possible to find their marginal distributions \($f_X(x)$\) and \($f_Y(y)$\) or compute the joint probability.
In general, to find the marginal distribution of \($X$\), we integrate the joint probability distribution over all possible values of \($Y$\):
\($$f_X(x)=\int_{-\infty}^{\infty} f_{X, Y}(x, y) d y$$\)
Similarly, to find the marginal distribution of \(Y\), we integrate the joint probability distribution over all possible values of \(X\) :
\($$f_Y(y)=\int_{-\infty}^{\infty} f_{X, Y}(x, y) d x$$\)
To compute the joint probability, we use the joint probability density function:
\($$P\{(X, Y) \in A\}=\iint_A f_{X, Y}(x, y) d x d y$$\)
where \(\mathrm{~A}\) is some region in the \((x, y)\)-plane.

For this visualization, a bar chart would be the best choice.
A bar chart is an effective way to visually compare different categories or groups. In this case, the data analyst can create a bar chart where each bar represents a city, and the height of the bar corresponds to the population of that city. The analyst can include only the top ten most populous cities in North Carolina and color the bars differently based on whether the population is below or above 250,000 people. By doing so, it becomes easy to identify which cities fall below the threshold, as they will have shorter bars compared to those above the threshold.
