The pentagons JKLMN and PQRST are similar.
Find the length x of RS.
The length of the segment SR for the given pentagons is 9 units.
What is a pentagon?A polygon having 5 sides and 5 angles is called a pentagon. The words "pentagon" (which implies five angles) are formed up of two other terms, namely Penta and Gonia. End to end, the sides of a pentagon come together to form a shape. Hence, there are 5 sides in a pentagon.
The pentagon is a polygon with five sides and five angles, just like other polygons including triangles, quadrilaterals, squares, and rectangles. There are several sorts of pentagon forms, including regular and irregular pentagons as well as convex and concave pentagons, depending on the sides, angles, and vertices.
We know that, for similar figures the length of the ratios of their corresponding segments are equal.
Thus,
NM/TS = ML/SR
4/7.2 = 5/x
Using cross multiplication we have:
4x = 5(7.2)
4x = 36
x = 9
Hence, the value of the segment SR for the given pentagons is 9 units.

T/F Solution that can be analytically obtained but is not an actual answer to the equation often due to restrictions in the type of function such as a negative in the log
T/F Solution that can be analytically obtained but is not an actual answer to the equation often due to restrictions in the type of function such as a negative in the log
This statement is true.
Because, Sometimes, when solving an equation using analytical methods, we may arrive at a solution that is mathematically correct but is not a valid answer due to the restrictions in the type of function used.
For example, if a negative value appears in the logarithmic function, the solution may not be valid because the logarithmic function is only defined for positive values.
In such cases, we need to go back and recheck our work and take into account the restrictions of the function to arrive at a valid solution.
Sometimes when solving an equation analytically, the resulting solution may not be a valid answer due to restrictions in the domain of the function.
For example, if we solve an equation involving a logarithmic function, we may end up with a negative value inside the logarithm, which is not defined for real numbers. In such cases, the solution obtained analytically is not a valid answer to the equation.
Another example is when solving for the roots of a quadratic equation using the quadratic formula, we may obtain complex solutions even though we are only interested in real solutions.
Thus, it is important to always check the solutions obtained to ensure that they satisfy any domain or range restrictions of the functions involved in the equation.

A random variable has a triangular probability density function with a = 50, b = 375, and m = 250.
what is the probability that the random variable will assume a value greater than 290? if required, round your answer to four decimal places.
The probability that the random variable will assume a value greater than 290 is 0.1778.
Given that :
a = 50, b = 375 and m = 250.
The maximum is 375 and the minimum is 50.
Here the mode is 250.
The value of x = 290 is greater than the mode.
x greater than 290 means 290 < x < 375.
This is triangular distribution.
P(x > 300) = P(290 < x < 375)
= \(2\int\limits^{375}_{290} {\frac{(375-x)}{(375-50)(375-250)} } \, dx\)
Now take the constant outside the integral.
P(x > 300) = \(\frac{2}{40625} \int\limits^{375}_{290} {(375-x)} \, dx\)
Integrating, we get (375x - x²/2).
Substitute the upper and lower limits.
P(x > 300) = 2/40625 {[(375)(375)-(375²/2)] - (375)(290)-(290²/2)]}
= 0.177846
Hence the probability is 0.1778.

A statistician has analysed the duration of audience laughter after a stand up comedian's jokes. The data showed that the laughter duration was evenly distributed between 4 seconds and 9.7 seconds. Then, the probability that the laughter after one of this comedian's jokes lasts for more than 7 seconds is
Answer:
The probability that the laughter after one of the comedians jokes lasts for more than 7 seconds is approximately 0.474
Step-by-step explanation:
The nature of the distribution of the given data = Evenly distributed data
The range of the laughter times = Between 4 seconds and 9.7 seconds
The probability density function, f(x), is given as follows;
\(f(x) = \dfrac{1}{b - a}\)
The mean of the uniform distribution, μ, is given as follows;
\(\mu = \dfrac{a + b}{2}\)
The standard deviation, σ, is given as follows;
\(\sigma = \sqrt{\dfrac{\left (b - a\right)^2}{12} }\)
Where;
a = 4, and b = 9.7, we have;
μ = (4 + 9.7)/2 = 6.85
σ = √((9.7 - 4)²/12) ≈ 1.64545
The probability density function, f(x) = 1/(b - a) for a ≤ x ≤ b
∴ f(x) = 1/(9.7 - 4)
For P(x > 7), we have;
P(x > 7) = 1 - P(x < 7) = 1 - (7 - 4) × 1/(9.7 - 4) ≈ 0.474
The probability that the laughter after one of the comedians jokes lasts for more than 7 seconds P(x >7) ≈ 0.474.

Step-by-step explanation:
y = mx + b
First, we will find 'm', aka slope,
(\(y_{2}\) - \(y_{1}\) ) / (\(x_{2}\) - \(x_{1}\)) = m
(-7 -7)/ (4 - (-3)) = m
-14/ 7 = m
∴ m = -2
Then we can substitute m = -2 and point 1 in to find 'b', aka y-intercept,
7 = -2 (-3) + b
7 = 6 + b
7 - 6 = b
∴ b = 1

Consider a partial output from a cost minimization problem that has been solved to optimality. Final Shadow Constraint Allowable Allowable Name Value Price R.H. Side Increase Decrease Labor Time 700 -6 700 100 200 The Labor Time constraint is a resource availability constraint. What will happen to the dual value (shadow price) if the right-hand-side for this constraint decreases to 400? o It will become a more negative number, such as -8. O It will become zero. O It will become zero or less negative. It will remain at -6. O It will become a less negative number, such as -4.
The shadow price for the labor time constraint will remain at -6, regardless of whether the right-hand-side decreases to 400 or not. So the answer is: It will remain at -6.
The labor time constraint has a shadow price of -6, which means that for every unit decrease in the right-hand-side (R.H. Side) of this constraint, the optimal objective function value will decrease by $6.
If the right-hand side for this constraint decreases to 400, the allowable decrease in the right-hand side is 300 (i.e., 700 - 400).
The allowable increase on the right-hand side is also 300. Since the constraint has been solved to optimality, any change in the right-hand side within the allowable range will not change the optimal solution.

Trying to get the right number possible. What annual payment is required to pay off a five-year, $25,000 loan if the interest rate being charged is 3.50 percent EAR? (Do not round intermediate calculations. Round the final answer to 2 decimal places.Enter the answer in dollars. Omit $sign in your response.) What is the annualrequirement?
To calculate the annual payment required to pay off a five-year, $25,000 loan at an interest rate of 3.50 percent EAR, we can use the formula for calculating the equal annual payment for an amortizing loan.
The formula is: A = (P * r) / (1 - (1 + r)^(-n))
Where: A is the annual payment,
P is the loan principal ($25,000 in this case),
r is the annual interest rate in decimal form (0.035),
n is the number of years (5 in this case).
Substituting the given values into the formula, we have:
A = (25,000 * 0.035) / (1 - (1 + 0.035)^(-5))
Simplifying the equation, we can calculate the annual payment:
A = 6,208.61
Therefore, the annual payment required to pay off the five-year, $25,000 loan at an interest rate of 3.50 percent EAR is $6,208.61.

to write an equation of the line that is...
perpendicular to y= 2x - 3
and goes through the point (-4, 5)
Answer:
\(y = -\frac{1}{2} x + 3\)
Step-by-step explanation:
Perpendicular lines have a negative reciprocal gradient to the original line. This means you have to make the gradient negative and flip the original fraction.
The original gradient is 2 (which can be written 2/1), so the reciprocal is 1/2 and made negative it is -1/2.
Put this into the equation using form y = mx +c to get y = -1/2x + c.
To work out c, substitute the values of x and y given in the point:
5 = -1/2(-4) + c
5 = 2 + c
c = 3
Therefore, the equation for the perpendicular is:
\(y = -\frac{1}{2} x + 3\)
A city had a population of 6,506 at the begining of 1977 and has been growing at 8% per year since then. (a) Find the size of the city at the beginning of 2003. Answer: (b) During what year will the population of the city reach 14,166,171 ?
The size of the city at the beginning of 2003 is 16,261. The population of the city will reach 14,166,171 in the year 2062.
(a) To find the size of the city at the beginning of 2003, we need to calculate the population after 26 years of growth. Since the city has been growing at a rate of 8% per year, we can use the formula for compound interest to calculate the population:
Population = Initial Population * (1 + Growth Rate)^Number of Years
Substituting the given values into the formula, we get:
Population = 6,506 * (1 + 0.08)^26 = 16,261
Therefore, the size of the city at the beginning of 2003 is 16,261.
(b) To determine the year when the population of the city will reach 14,166,171, we need to find the number of years it takes for the population to grow from 6,506 to 14,166,171 at a growth rate of 8% per year. Again, we can use the compound interest formula and solve for the number of years:
14,166,171 = 6,506 * (1 + 0.08)^Number of Years
Dividing both sides of the equation by 6,506 and taking the logarithm, we can solve for the number of years:
log(14,166,171 / 6,506) / log(1 + 0.08) ≈ 50.56
Therefore, the population of the city will reach 14,166,171 in approximately 50.56 years. Since the population growth is counted from the beginning of 1977, we need to add this to find the year:
1977 + 50.56 ≈ 2062
Thus, the population of the city will reach 14,166,171 in the year 2062.

Answer:

Step-by-step explanation:
Hi there!
1) Find the length of the other leg in the right triangle
There are two ways we can go about this. The first way is to use trigonomic ratios:
We're given one of the legs and we're trying to solve for the other, so we can use the tangent ratio:
\(tan\theta=\frac{opp}{adj}\)
Let x be equal to the length of the other leg. Plug in the known values:
\(tan45=\frac{x}{7}\\7*tan45=x\\x=7\)
The other way to find this is to observe the angles. Because we're given that two of the angles are 45 and 90 degrees, we know that the third angle is 45 degrees. This makes this an isosceles triangle, meaning the other leg is 7 ft long.
2) Determine the height of the hoop
Add 7 ft and 5 ft (the person's height):
7+5=12 ft

Based on this data, what is a reasonable estimate of the probability that it is sunny tomorrow?
The reasonable estimate of the probability that it is sunny tomorrow is option D: 25%
What is the probability?The concept of probability is determining the chance or likelihood of a certain event occurring. When we lack certainty regarding the result of a happening, we can discuss the chances of particular consequences, which denote their level of probability. The value of probability is one that ranges form 0-1
From the graph,
Numbers of days of weather that is sunny is = 3Total numbers of days of weather = days of weather that is sunny + days of weather that is rainy + days of weather that is snowy
= 3 + 5 + 2 + 2 = 12
So, the probability of days of weather to be sunny + 3.12 = 1/4
