The center of an airplane propeller is 13 feet off the ground and the radius of the propeller is 3 feet. The blades of the propeller are set at radians from 0 radians directly to the right of the center of the propeller.
The motion of the blades of the propeller is given by:
f(x) = 3ft*sin(kx) + 13ft
Which equation describes the motion of the blades?It will be described by a sine function of the form:
f(x) = B*sin(k*x) + M
M is the midpoint, which coincides with the center of the propeller, so M = 13ft.
The amplitude B will be equal to the radius, B = 3ft.
And we know that when x = 0 (at the initial time) the propeller is set to the right, that is why we use a sine function, that becomes zero when x = 0.
Finally, the constant k will be related to the frequency, and it will depend on how fast the blades move.
f(x) = 3ft*sin(kx) + 13ft

diced turnip in a particular restaurant has a yield percentage of 88%. if a cook begins with 38 ounces of turnips, how many ounces of diced turnips should she expect to yield after processing?
The cook should expect to yield 33.44 ounces of diced turnips after processing if a cook begins with 38 ounces of turnips with yield percentage of 88%.
When the cook begins with 38 ounces of turnips, she should expect a yield of 88% for diced turnips. This means that after processing, 88% of the original weight of turnips will remain as diced turnips.
To calculate the expected yield of diced turnips, we can use the formula
Expected yield = Original weight of turnips x Yield percentage / 100
Plugging in the values given, we get:
Expected yield = 38 ounces x 88 / 100
Expected yield = 33.44 ounces
Therefore, the cook should expect to yield 33.44 ounces of diced turnips after processing. This calculation assumes that the yield percentage is accurate and that the processing of turnips is consistent. By using the expected yield, the cook can estimate the amount of diced turnips that can be prepared for a dish, ensuring that there is enough supply for customers while minimizing waste.

Answer: no solution
Step-by-step explanation:
Answer:
no solutions
Step-by-step explanation:
In order for the system to have solutions, x and y must work for both equations.
The easiest way to solve this is the isolate the y variable on both equations and then solve for x:
1. x+y=5
y=5-x
2. x+y=6
y=6-x
Since the y variables for both equations should be the same, let us make a new equation:
6-x=5-x
6=5
Hmm... This doesn't seem to work! 6 does not equal to 5. Therefore, there are no solutions.

Below are the jorsey numbers of 11 players randomly solected from a football tearn Find the range, variance, and standard deviation for the given sample data What do the results teli us? 33747065564739725794150 Range = (Round to one decimal place as needed) Sample standard deviation = (Round to one decimal place as needed) Sample variance = (Round to one decimal place as needed) What do the results tell us? A. Jersey numbers on a football team do not vary as much as expected. B. The sample standard deviation is too large in companson to the range. C. Jersey numbers on a footbas team vary much mofe than expected D. Jersey numbers ate nominal data that are just replacemonts for names, so the resulling statistics are meaningiess:
The results tell us that jersey numbers on a football team vary much more than expected, as evidenced by the large range and standard deviation. The sample variance is also relatively high, indicating that there is a fair amount of variability among the jersey numbers in the sample. These statistics are meaningful and can provide insight into the distribution of jersey numbers on the team.
To find the range, we need to subtract the smallest number from the largest number in the sample. So, the range is:
94 - 15 = 79
To find the sample variance and standard deviation, we first need to find the mean of the sample. We can do this by adding up all the numbers and dividing by the total number of players:
(33 + 74 + 70 + 65 + 56 + 47 + 39 + 72 + 57 + 94 + 15) / 11 = 54.18
Next, we need to find the difference between each number and the mean, square them, and add them up. This gives us the sum of squares:
[(33 - 54.18)^2 + (74 - 54.18)^2 + (70 - 54.18)^2 + (65 - 54.18)^2 + (56 - 54.18)^2 + (47 - 54.18)^2 + (39 - 54.18)^2 + (72 - 54.18)^2 + (57 - 54.18)^2 + (94 - 54.18)^2 + (15 - 54.18)^2] = 15864.4
The sample variance is then calculated by dividing the sum of squares by the total number of players minus one:
15864.4 / 10 = 1586.44
Finally, we can calculate the sample standard deviation by taking the square root of the variance:
√1586.44 ≈ 39.83
The results tell us that jersey numbers on a football team vary much more than expected, as evidenced by the large range and standard deviation. The sample variance is also relatively high, indicating that there is a fair amount of variability among the jersey numbers in the sample. These statistics are meaningful and can provide insight into the distribution of jersey numbers on the team.

In 2010, the population of a city was 191,000. From 2010 to 2015, the population grew by 3.9%. From 2015 to 2020, it fell by 3.3%. To the nearest 100 people, what was the population in 2020?
Answer:
The population by 2020 is 191,900
Step-by-step explanation:
Given that;
population 2010 (population in 2010): 191000
the population grew from 2010 to 2015: by 3.9%
so, population by 2015 = \(191000(1 + \frac{3.9}{100})\)
= \(191000(1 + 0.039)\)
= \(191000(1.039)\)
= \(198449\)
the population drop from 2015 to 2020: 3.3%
so, population by 2015 = \(198449(1 - \frac{3.3}{100})\)
= \(198449(1 - 0.033)\)
= \(198449(0.967)\)
= \(191,900.183\)

c. A personal trainer gathers data on the weights and time spent in the gym for each of her clients.
a. Predictor (x): odometer readings. Response (y): price.
b. Predictor (x): household size. Response (y): monthly water bill.
c. Predictor (x): time spent in the gym. Response (y): weight.
a. In this case, we want to predict the price of a used car based on its odometer reading. The price is the response variable, and the odometer reading is the predictor variable. It is reasonable to assume that the more miles a car has on it, the lower its value will be, all else being equal.
b. In this case, we want to predict the monthly water bill based on household size. The monthly water bill is the response variable, and the household size is the predictor variable. It is reasonable to assume that the more people living in a household, the higher their monthly water bill will be, all else being equal.
c. In this case, we want to predict a client's weight based on the time they spend in the gym. Weight is the response variable, and time spent in the gym is the predictor variable. It is reasonable to assume that the more time a person spends in the gym, the more likely they are to lose weight or maintain a healthy weight, all else being equal.

An object is moving at a speed of 2 centimeters ever 7 seconds. express this speed in meters per week.
The speed of the object is 12121 m per week.
What does it mean to do speed?
“Speed” is a street name for various stimulant drugs that teens, young adults and others use to feel more alert and focused, and in some cases, to feel high. Some people also use various forms of speed to reduce their appetite. Types of speed include: Amphetamines (used to treat ADHD, narcolepsy, and depression)The object is moving at a speed of 2 centimeters every 7 seconds.
We need to find the speed in m per week.
2 cm = 0.02 m
1 week = 604800 s

If you know the volume of an object in cubic inches, can you find its volume in cubic feet by dividing by 12 Discuss
The answer is yes, you can find the volume of an object in cubic feet by dividing its volume in cubic inches by 12^3 (or 1728).
This is because 1 cubic foot is equal to 12 inches in length, 12 inches in width, and 12 inches in height, which means that it contains 1728 cubic inches.
Lets take we have a cube with a volume of 1000 cubic inches. To find its volume in cubic feet, you would divide 1000 by 1728, which gives you approximately 0.5787 cubic feet. This means that the cube is slightly more than half a cubic foot in volume.
It's important to note that when converting between cubic inches and cubic feet, you're essentially changing the unit of measurement. This doesn't affect the actual volume of the object, just the way you express it. For example, a cube with a volume of 1000 cubic inches and a cube with a volume of 0.5787 cubic feet are the same size, they're just measured in different units.
In summary, if you know the volume of an object in cubic inches, you can find its volume in cubic feet by dividing by 1728, which is the conversion factor between the two units.

On a number line, the coordinates of J,K,L,M,N are -10.5,-4,-1,1.5,4 respectively. Find the lengths of the two segments. Are they congruent? bar (JK) and bar (KM)
The lengths of the two segments, bar (JK) and bar (KM), are as follows:
1. Length of bar (JK): |JK| = |-4 - (-10.5)| = |-4 + 10.5| = |6.5| = 6.5 units.
2. Length of bar (KM): |KM| = |1.5 - (-4)| = |1.5 + 4| = |5.5| = 5.5 units.
The two segments, bar (JK) and bar (KM), are not congruent because their lengths are different.
To find the length of a line segment on a number line, we take the absolute value of the difference between the coordinates of the two endpoints.
For bar (JK), we subtract the coordinate of point J from the coordinate of point K. The difference is -4 - (-10.5) = -4 + 10.5 = 6.5 units.
For bar (KM), we subtract the coordinate of point K from the coordinate of point M. The difference is 1.5 - (-4) = 1.5 + 4 = 5.5 units.
Since the lengths of bar (JK) and bar (KM) are 6.5 units and 5.5 units, respectively, they are not congruent.
