A plane flying with a constant speed of 14 km/min passes over a ground radar station at an altitude of 11 km and climbs at an angle of 25 degrees. At what rate is the distance from the plane to the radar station increasing 4 minutes later?
The distance is increasing at equation editorEquation Editor____ km/min.
Answers
Answer:
[tex]\frac{dc}{dt}\approx13.8146\text{ km/min}[/tex]
Step-by-step explanation:
We know that the plane travels at a constant speed of 14 km/min.
It passes over a radar station at a altitude of 11 km and climbs at an angle of 25°.
We want to find the rate at which the distance from the plane to the radar station is increasing 4 minutes later. In other words, if you will please refer to the figure, we want to find dc/dt.
First, let's find c, the distance. We can use the law of cosines:
[tex]c^2=a^2+b^2-2ab\cos(C)[/tex]
We know that the plane travels at a constant rate of 14 km/min. So, after 4 minutes, the plane would've traveled 14(4) or 56 km So, a is 56, b is a constant 11. C is 90+20 or 115°. Substitute:
[tex]c^2=(56)^2+(11)^2-2(56)(11)\cos(115)[/tex]
Evaluate:
[tex]c^2=3257-1232\cos(115)[/tex]
Take the square root of both sides:
[tex]c=\sqrt{3257-1232\cos(115)}[/tex]
Now, let's return to our law of cosines. We have:
[tex]c^2=a^2+b^2-2ab\cos(C)[/tex]
We want to find dc/dt. So, let's take the derivative of both sides with respect to t:
[tex]\frac{d}{dt}[c^2]=\frac{d}{dt}[a^2+b^2-2ab\cos(C)][/tex]
Since our b is constant at 11 km, we can substitute this in:
[tex]\frac{d}{dt}[c^2]=\frac{d}{dt}[a^2-(11)^2-2a(11)\cos(C)][/tex]
Evaluate:
[tex]\frac{d}{dt}[c^2]=\frac{d}{dt}[a^2-121-22a\cos(C)][/tex]
Implicitly differentiate:
[tex]2c\frac{dc}{dt}=2a\frac{da}{dt}-22\cos(115)\frac{da}{dt}[/tex]
Divide both sides by 2c:
[tex]\frac{dc}{dt}=\frac{2a\frac{da}{dt}-22\cos(115)\frac{da}{dt}}{2c}[/tex]
Solve for dc/dt. We already know that da/dt is 14 km/min. a is 56. We also know c. Substitute in these values:
[tex]\frac{dc}{dt}=\frac{2(56)(14)-22\cos(115)(14)}{2\sqrt{3257-1232\cos(115)}}[/tex]
Simplify:
[tex]\frac{dc}{dt}=\frac{1568-308\cos(115)}{2\sqrt{3257-1232\cos(115)}}[/tex]
Use a calculator. So:
[tex]\frac{dc}{dt}\approx13.8146\text{ km/min}[/tex]

The sum of the angles around point O = 360°, thus
x + 3x + 256 = 360 , that is

the scores on a collegiate mathematics readiness assessment are approximately normally distributed with a mean of 680 and a standard deviation of 120. determine the percentage of scores between 690 and 900, to the nearest percent.
Answers
43.36% of the scores fall between 690 and 900 on the collegiate mathematics readiness assessment.
To determine the percentage of scores between 690 and 900, we need to calculate the area under the normal distribution curve between these two values.
First, we need to standardize the scores using the formula z = (x - μ) / σ, where x is the score, μ is the mean, and σ is the standard deviation.
For the score 690:
z1 = (690 - 680) / 120 = 0.0833
For the score 900:
z2 = (900 - 680) / 120 = 1.8333
Next, we need to find the area between these two standardized scores. We can use a standard normal distribution table or a statistical calculator to find the corresponding probabilities.
From the standard normal distribution table, we find that the area to the left of z1 is approximately 0.5328 and the area to the left of z2 is approximately 0.9664.
To find the area between z1 and z2, we subtract the smaller area from the larger area:
Area = 0.9664 - 0.5328 = 0.4336
Finally, we convert the area to a percentage by multiplying by 100:
Percentage = 0.4336 * 100 ≈ 43.36%
Therefore, approximately 43% of the scores fall between 690 and 900 on the collegiate mathematics readiness assessment.

Answers
According to the diagram provided, Kyle is creating a frame for a model car by placing two rods together. To justify why AB equals 10, we can use the Segment Addition Postulate.
The Segment Addition Postulate states that if three points A, B, and C are collinear (meaning they lie on the same line), then point B is between points A and C if and only if the sum of the lengths of segments AB and BC is equal to the length of segment AC. In this case, the diagram shows points A, B, and C on a line, where A is the left endpoint, B is the midpoint, and C is the right endpoint. Since point B is the midpoint of segment AC, it divides the segment into two equal parts. Therefore, the length of segment AB is equal to the length of segment BC, and since the lengths are equal, we can conclude that AB is equal to 10 units. Hence, the justification for AB being 10 is based on the Segment Addition Postulate, as it guarantees that point B is the midpoint of segment AC.

The sales taken in for tickets to an ice-skating rink is recorded on a quarterly basis, for a period of 8 quarters. 1 2 3 4 5 6 7 8 Quarter Sales (£) 7555 6695 5415 4150 7310 7015 5435 3885 (a) Describe any short term, seasonal or cyclical trends in the data. (b) Calculate the 3 period moving averages for the data. (c) Plot your moving averages on the graph below. (d) Make a prediction for the sales taken in for the following 2 quarters.
Answers
(a) Based on the given data, there appear to be short-term fluctuations in the sales of the ice-skating rink. The sales figures vary from quarter to quarter, with some quarters showing higher sales and others showing lower sales. This suggests the presence of short-term or seasonal trends in the data. For example, there is a notable increase in sales in quarters 1, 5, and 6, followed by a decrease in quarters 3, 4, and 8. This pattern indicates a possible seasonal or cyclical trend in the sales of the ice-skating rink.
(b) To calculate the 3-period moving averages, we take the average of the sales data over a window of three consecutive quarters and compute the average for each subsequent quarter. The moving averages smooth out the fluctuations in the data and provide a clearer picture of the underlying trend.
Quarter 1: (7555 + 6695 + 5415) / 3 = 6555
Quarter 2: (6695 + 5415 + 4150) / 3 = 5420
Quarter 3: (5415 + 4150 + 7310) / 3 = 5625
Quarter 4: (4150 + 7310 + 7015) / 3 = 6158.33
Quarter 5: (7310 + 7015 + 5435) / 3 = 6586.67
Quarter 6: (7015 + 5435 + 3885) / 3 = 5445
Quarter 7: (5435 + 3885 + 0) / 3 = 3106.67
Quarter 8: (3885 + 0 + 0) / 3 = 1295
(c) The moving averages can be plotted on a graph with the x-axis representing the quarters and the y-axis representing the sales figures. Each moving average value is plotted in the corresponding quarter.
(d) Based on the calculated moving averages, we can make a prediction for the sales taken in the following two quarters. The prediction will be the average of the sales figures for the last three quarters.
Prediction for Quarter 9: (7015 + 5435 + 3885) / 3 = 5445
Prediction for Quarter 10: (5435 + 3885 + 0) / 3 = 3106.67
Therefore, the prediction for the sales taken in the following two quarters is £5,445 for Quarter 9 and £3,107 for Quarter 10.

a developer wants to develop a 16-acre subdivision. he figures that the streets and common area will take up about 30% of this overall area. if the minimum lot size is to be 12,000 sf, how many lots can the developer have on this property?
Answers
The developer can have a maximum of 40 lots on the 16-acre subdivision.
To calculate the number of lots the developer can have on the 16-acre subdivision, we need to subtract the area occupied by streets and common areas from the total area and then divide it by the minimum lot size.
1 acre is equal to 43,560 square feet, so 16 acres is equal to 16 * 43,560 = 696,960 square feet.
The streets and common areas will take up 30% of this overall area:
30% of 696,960 = 0.3 * 696,960 = 209,088 square feet.
Now we subtract the area occupied by streets and common areas from the total area to find the area available for the lots:
696,960 - 209,088 = 487,872 square feet.
Since the minimum lot size is 12,000 square feet, we divide the available area by the minimum lot size to find the number of lots:
487,872 / 12,000 = 40.656.
Since we cannot have a fraction of a lot, the developer can have a maximum of 40 lots on this property.
As a result, the 16-acre subdivision may only accommodate a maximum of 40 lots from the developer.

If a vehicle averages 23 mi/h on a 138 mi trip and then returns over the same 138 mi at the rate of 69 mi/h, what is your average speed for the trip? Give reasons for your answer. A vehicle averages 23 mi/h on a 138 mi trip. Write the integral that represents this information. f(x)dx = 0
Answers
The correct answer is the average speed for the entire trip is 34.5 miles per hour and The integral that represents this information is as follows: f(x)dx = ∫23 dx + ∫69 dx Where x represents the distance travelled in miles.
To find out the average speed for the entire trip, we will use the formula for average speed which is given as follows: Average speed = Total distance/Total time
Let's calculate the time taken to travel 138 miles at 23 mi/h
Speed = 23 mi/h
Distance = 138 mi
Time taken = Distance/Speed = 138/23 = 6 hours
Now, let's calculate the time taken to return back to the starting point, which is again 138 miles away but this time at 69 mi/h.
Speed = 69 mi/h
Distance = 138 mi
Time taken = Distance/Speed = 138/69 = 2 hours
Now, the total time taken for the entire trip is 6 + 2 = 8 hours.
The total distance travelled for the entire trip is 2 x 138 = 276 miles.
Now we can use the formula for average speed to calculate the average speed of the entire trip.
Average speed = Total distance/Total time = 276/8 = 34.5 miles per hour
Therefore, the average speed for the entire trip is 34.5 miles per hour.
The integral that represents this information is as follows: f(x)dx = ∫23 dx + ∫69 dx Where x represents the distance travelled in miles.
The limits of integration are from 0 to 138 for both integrals, representing the forward and backward journeys.
