Answer:
x = 10; y = 10
Step-by-step explanation:
\( \sin(theta) = \frac{opposite}{hypotenuse} \)
\( \cos( {theta} ) = \frac{adjacent}{hypotenuse} \)
\( \tan( {theta} ) = \frac{opposite}{adjacent} \)
theta = 45°
opposite = x
hypotenuse = 10√2
adjacent = y
1) find x using sin formula\( \sin(theta) = \frac{opposite}{hypotenuse} \)
\( \sin(45) = \frac{x}{10 \sqrt{2} } \)
\( \sin(45) \times 10 \sqrt{2} = x\)
\(10 = x\)
\(x = 10\)
2) find y using cos formula\( \cos( {theta} ) = \frac{adjacent}{hypotenuse} \)
\( \cos(45) = \frac{y}{10 \sqrt{2} } \)
\( \cos(45) \times 10 \sqrt{2} = y\)
\(10 = y\)
\(y = 10\)
slope –2/3, y intercept (0,-9)
Step-by-step explanation:
Given
Slope (m) = - 2/3
Y-intercept (c) = - 9
Writing in slope intercept form
y = mx + c
y = - 2/3 x - 9
Hope it helps. :)
Answer:
Step-by-step explanation:
m = -2/3 ; (0 , -9)
y - y1 = m(x -x1)
\(y -[-9]= \frac{-2}{3}(x - 0)\\\\y + 9 = \frac{-2}{3}x\\\\ y = \frac{-2}{3}x -9\)
The standard deviation is _____ when the data are all concentrated close to the mean, exhibiting little variation or spread.
The standard deviation is relatively small when the data are all concentrated close to the mean, exhibiting little variation or spread.
The standard deviation could be a degree of the changeability or spread of a set of information. It is calculated by finding the square root of the normal of the squared contrasts between each information point and the cruel(mean).
In other words, it tells us how much the information values are scattered around the mean.
When the information is all concentrated near the cruel(mean), it implies that the contrasts between each information point and the cruel are moderately little.
This comes about in a little while of squared contrasts, which in turn leads to a little standard deviation. On the other hand, when the information is more spread out, it implies that the contrasts between each information point and the cruel are bigger.
This comes about in a bigger entirety of squared contrasts, which in turn leads to a bigger standard deviation.
For case, let's consider two sets of information:
Set A and Set B.
Set A:
2, 3, 4, 5, 6
Set B:
1, 3, 5, 7, 9
Both sets have the same cruel(mean) (4.0), but Set A encompasses a littler standard deviation (1.4) than Set B (2.8).
This is because the information values in Set A are all moderately near to the cruel(mean), while the information values in Set B are more spread out.
Subsequently, we will say that the standard deviation is generally small when the information is all concentrated near the mean, showing a small variety or spread.

The Laplace transform Y(s) of the solution y(t) to the given initial value problem is Y(s) = (3s + 9) / (s^2 + 6s + 18).
To solve the given initial value problem \(y'' + 6y' + 18y = 38(t - \pi)\) with \(y(0) = 3\) and \(y'(0) = 9\), we can use the Laplace transform method. The Laplace transform of a function \(y(t)\) is denoted as \(Y(s)\) and is obtained by applying the Laplace transform operator to both sides of the differential equation.
Applying the Laplace transform to the given differential equation, we obtain the algebraic equation \[s^2Y(s) - sy(0) - y'(0) + 6sY(s) - 6y(0) + 18Y(s) = 38\left(\frac{1}{s} - \frac{e^{-\pi s}}{s}\right).\] Substituting the initial conditions \(y(0) = 3\) and \(y'(0) = 9\), we can simplify the equation to \[(s^2 + 6s + 18)Y(s) - (3s + 9) = 38\left(\frac{1}{s} - \frac{e^{-\pi s}}{s}\right).\]
To find \(Y(s)\), we rearrange the equation and solve for \(Y(s)\): \[Y(s) = \frac{3s + 9 + 38\left(\frac{1}{s} - \frac{e^{-\pi s}}{s}\right)}{s^2 + 6s + 18}.\]
In the second paragraph, we can further simplify the expression for \(Y(s)\) by performing algebraic manipulations. By multiplying out the numerator and denominator and combining like terms, we can obtain a more concise form of \(Y(s)\). However, without the specific values for \(s\) and \(\pi\), it is not possible to determine the exact numerical expression for \(Y(s)\).

Dylan just started a running plan where he runs 14 miles the first week and then increases the number of miles he runs by 10% each week. If he keeps up this plan for 11 weeks, how many total miles would Dylan have run, to the nearest whole number?
Answer:
36 miles
Step-by-step explanation:
Given - Dylan just started a running plan where he runs 14 miles the first
week and then increases the number of miles he runs by 10% each
week.
To find - If he keeps up this plan for 11 weeks, how many total miles would
Dylan have run ?
Proof -
1st week = 14 miles
2nd week = 14 + 10% of 14 = 14 + 1.4 = 15.4
3rd week = 15.4 + 10% of 15.4 = 15.4 + 1.54 = 16.94
4th week = 16.94 + 10% of 16.94 = 16.94 + 1.694 = 18.634
5th week = 18.634 + 10% of 18.634 = 18.634 + 1.8634 = 20.4974
6th week = 20.4974 + 10% of 20.4974 = 20.4974 + 2.04974 = 22.54714
7th week = 22.54714 + 10% of 22.54714 = 22.54714 + 2.254714 = 24.801857
8th week = 24.801857 + 10% of 24.801857 = 24.801857 + 2.4801857 = 27.2820427
9th week = 27.2820427 + 10% of 27.2820427 = 27.2820427+ 2.72820427 = 30.01024697
10th week = 30.01024697 + 10% of 30.01024697 = 30.01024697 + 3.001024697 = 33.01127167
11th week = 33.01127167 + 10% of 33.01127167 = 33.01127167 + 3.301127167 = 36.31239884 ≈ 36
∴ we get
Total miles Dylan would run = 36 miles.
The mean and the median are closely related concepts. The median is the numerical value separating the higher half of your data from the lower half. You can find the median by arranging all of the observations from lowest value to highest value and picking the middle value​ (assuming you have an odd number of​ observations). Although the mean and median are closely​ related, the difference between the mean and the median is sometimes of interest.
Suppose Country A has five families. Their incomes are $9000, $21,000, $29,000, $39,000, and $50,000.
Country A's median income is _______, and its mean income is ______.
Suppose country B also has five familities. Their incomes are $9000, 21000, 29000, 39000, and 151000.
Country B's median income is _____ and its mean income is ____.
Country _____ has a greater income inequality
Based on your answers to this​ question, would you expect the ratio of the mean income in the United States to the median income has risen or​ fallen? Explain.
A.
​Fallen, because means change less with standard deviation.
B.
​Risen, because means change more with extreme values.
C.
​Risen, because means increase but medians decrease with income.
D.
​Risen, because medians increase with variance but means do not.
Mean of country A is $29600 and median $29000. Mean of country B is $49800 and median is $29000. Country B has greater income inequality. So option B is the correct answer.
Mean of incomes in country A = (9000+ 21000+ 29000 + 39000+ 50000)/5 = $29600
Median income of country A = (5+1)/2 th term = 3rd term = $29000
Mean to median ratio = 29600/ 26000= 1.02
Mean income of country B = ( 9000+ 21000+ 29000+ 39000+ 151000)/5 = $ 49800
Median income = (n+1)/2 th term = (5+1)/2 = 3rd term = 29000
Mean to median ratio of country B = 49800/29000 = 1.71
Since mean and median are closer to each other, standard deviation is less. The mean to median ratio is greater for country B. So country B has greater income inequality.
If the income inequality has been increasing, then the mean-median ratio will increase, due to the extreme values, mean will increase. So option B is the correct answer.

A triangular prism is 12 meters long and has a triangular face with a base of 8 meters and a height of 9 meters. What is the volume of the triangular prism?
The volume of the triangular prism is 216 cubic meters.
To find the volume of a triangular prism, we need to multiply the area of the triangular base by the length of the prism.
Calculate the area of the triangular base.
The base of the triangular face is given as 8 meters, and the height is 9 meters. We can use the formula for the area of a triangle: area = (1/2) * base * height.
Plugging in the values, we get:
Area = (1/2) * 8 meters * 9 meters = 36 square meters.
Multiply the area of the base by the length of the prism.
The length of the prism is given as 12 meters.
Volume = area of base * length of prism = 36 square meters * 12 meters = 432 cubic meters.
Adjust for the shape of the prism.
Since the prism is a triangular prism, we need to divide the volume by 2.
Adjusted Volume = (1/2) * 432 cubic meters = 216 cubic meters.
Therefore, the volume of the triangular prism is 216 cubic meters.

d) neither its substitutes nor its complements. e) None of the above..
In question 27, the price elasticity of supply for shampoo is given as 20, and the price of shampoo increases by 0.7%. The expected change in the quantity of shampoo supplied can be determined using the concept of price elasticity of supply. However, the specific percentage change in quantity supplied is not provided, so a precise answer cannot be given based on the given information.
In question 20, an inferior good in which the income effect dominates the substitution effect is referred to as a Giffen good. It is not classified as a normal good, luxury good, mass-produced good, or favored good.
In question 30, the cross elasticity of demand measures the responsiveness of the quantity demanded of a particular good to changes in the prices of its substitutes and complements. The correct answer is that the cross elasticity of demand measures the responsiveness to changes in both substitutes and complements.
In question 27, without the specific percentage change in quantity supplied, we cannot determine the exact outcome based on the given information. The price elasticity of supply of 20 suggests that the quantity supplied is highly responsive to changes in price, but the specific percentage change in quantity supplied cannot be calculated without additional data.
In question 28, the relationship between pasta being a Giffen good and other characteristics is not specified. While pasta being a Giffen good indicates that the quantity demanded increases as the price increases, it does not imply whether pasta is a normal good, luxury good, or how price changes affect quantity demanded.

We have a pond which is completely filled with the water.
Area of the side face ( trapezium shaped)

Now,
⇒0.4 m³ water is taken out in 30 minutes
⇒1 m³ water is taken out in 30/0.4 minutes

It will take 2 hours and 55 minutes to hike to the camping spot and 1 hour and 10 minutes to set up the camp. What is the latest time Brett and his family can start hiking?
Brett and his family need to start hiking no later than 4:20 PM to reach their camping spot and set up camp before it gets dark.
To calculate the latest time Brett and his family can start hiking, we need to subtract the total time required for hiking and setting up the camp from the sunset time.
Total time required:
Hiking time: 2 hours 55 minutes = 2.92 hours
Setting up camp time: 1 hour 10 minutes = 1.17 hours
Total time required = Hiking time + Setting up camp time = 2.92 hours + 1.17 hours = 4.09 hours
Now, subtract the total time required from the sunset time:
Sunset time: 8:25 PM
Latest start time = Sunset time - Total time required
Latest start time = 8:25 PM - 4.09 hours
To subtract the hours and minutes, we need to convert 4.09 hours into minutes:
0.09 hours * 60 minutes/hour = 5.4 minutes
So, the latest start time is 8:25 PM - 4 hours 5.4 minutes:
Latest start time = 8:25 PM - 4 hours 5.4 minutes = 4:20 PM
