a 82-ft tree casts a shadow that is 110 ft long. what is the angle of elevation of the sun? (round your answer to one decimal place.)
Answers
The angle of elevation of the sun is, 36.7 degree.
What is angle of elevation?
The angle of elevation is the angle created between the line of sight and the horizontal. The angle created is an angle of elevation if the line of sight is upward from the horizontal line.
Given: A 82-ft tree casts a shadow that is 110 ft long.
So, by using the tangent ratio,
tanθ = 82/110
Apply tan^(-1) on both sides, we get
So, θ = \(tan^-^1(\frac{82}{110} )\)
θ = 36.7 degree.
Therefore, when a 82-ft tree casts a shadow that is 110 ft long, the angle of elevation of the sun is 36.7 degree.

Jason owns a food truck that sells tacos and burritos. He sells each taco for $4.75 and each burrito for $7.50. Yesterday Jason made a total of $790 in revenue from all burrito and taco sales and there were twice as many burritos sold as there were tacos sold. Write a system of equations that could be used to determine the number of tacos sold and the number of burritos sold. Define the variables that you use to write the system.
:)
Answers
Answer:
4.75t + 7.50b = 790
b = 2t
Step-by-step explanation:
Let t represent the number of tacos that he sold, and let b represent the number of burritos he sold.
4.75t can represent how much money he earned from selling tacos, and 7.50b can represent how much money he earned from selling burritos.
Create an equation that adds these together and sets them equal to 790:
4.75t + 7.50b = 790
Next, create another equation that represents how there were twice as many burritos sold than tacos.
This can be represented by b = 2t.
The system of equations is:
4.75t + 7.50b = 790
b = 2t

evaluate the line integral, where c is the given curve. c x sin(y) ds, c is the line segment from (0, 2) to (4, 5)
Answers
The solution of the line integral \(\int\limits t \sin(2+3t) , dt\).
What is integral?
The value obtained after integrating or adding the terms of a function that is divided into an infinite number of terms is generally referred to as an integral value.
To evaluate the line integral of the function f(x, y) = xsin(y) along the curve C which is the line segment from (0,2) to (4,5), we can parameterize the curve and then compute the integral.
Let's parameterize the curve
C with a parameter t such that x(t) and y(t) represent the x and y coordinates of the curve at the parameter value t.
Given that the curve is a line segment, we can use a linear interpolation between the initial and final points.
The parameterization is as follows:
x(t)=(1−t)⋅0+t⋅4=4t
y(t)=(1−t)⋅2+t⋅5=2+3t
Now, we can compute the line integral using the parameterization:
\(\int_{C} x \sin(y) , ds = \int_{a}^{b} f(x(t), y(t)) \cdot \left(x'(t)^2 + y'(t)^2\right) , dt\)
where a and b are the parameter values corresponding to the initial and final points of the curve.
Substituting the parameterization and evaluating the integral, we have:
\(\int_{C} x \sin(y) , ds = \int_{0}^{1} (4t) \sin(2+3t) \cdot \left(4^2 + 3^2\right) , dt\)
To evaluate this integral, numerical methods or approximations can be used.
To evaluate the given integral, we need to perform the integration on both sides of the equation.
On the left-hand side:
\(\int\limit_{C} x \sin(y) ds\)
On the right-hand side:
\(\int\limits_0^{1} (4t) \sin(2+3t) \cdot (4^2 + 3^2) , dt\)
Let's start by evaluating the integral on the right-hand side. The integral can be simplified as follows:
\(\int\limits_0^{1} (4t) \sin(2+3t) \cdot (4^2 + 3^2) , dt= 49 \int\limits_{0}^{1} t \sin(2+3t) , dt\)
Unfortunately, the integral \(\int\limits t \sin(2+3t) , dt\) does not have a simple closed-form solution. It requires numerical integration techniques or approximation methods to evaluate it.
However, it is important to note that the left-hand side of the equation is also in integral form and represents the length of curve C. Without knowing the specific curve C, it is not possible to evaluate the left-hand side of the equation without further information.
Therefore, the given integral cannot be evaluated without additional details about the curve C or without using numerical methods for approximating the right-hand side integral.
Hence, the solution of the line integral \(\int\limits t \sin(2+3t) , dt\).

Find the period and the amplitude of the periodic function. I'm awful with graphs :(
Answers
A period is the difference in x over which a sine function returns to its equivalent state and the amplitude is A/5.
Amplitude:
The amplitude of a periodic variable is a measure of its change over a period of time, such as a temporal or spatial period. The amplitude of an aperiodic signal is its magnitude compared to a reference value. There are various definitions (see below) of amplitude, which is any function of the magnitude of the difference between the extreme values of a variable. In the previous text, the phase of a periodic function is called the amplitude.
X = A sin (ω[ t - K]) + b
A is the amplitude (or peak amplitude),
x is the oscillating variable,
ω is angular frequency,
t is time,
K and b are arbitrary constants representing time and displacement respectively.
According to the Question:
An equation does not have an amplitude. This "equation" represents the formula of a vibration, and was better written as:
X= A/5* sin(1000.t + 120)
These oscillations have a certain amplitude. X values can vary from minimum to maximum. Normally, the stop position of the oscillation is X=0. In this case, we can see that the maximum occurs when the sine is +1 and the minimum occurs when the sine is -1.
For theses cases X= A/5 respectively -A/5.
Therefore,
The amplitude is A/5.
For formulas of this type, the term in front of the sinus (or cosine) is equal to the amplitude.

The Central Fabric Company purchases surplus bolts of fabric from two large textile mills, A and B. These fabrics are then sold to the public through bolts fabric stores, discount stores and direct mail. When Central receives the bolts, it separates them according to the market in which they are sold. Of the fabrics received from the textile mill A, 40 percent are sold to fabric stores, 10 percent in discount stores, and 30 percent by direct mail. The fabric received from textile mill B are 20 percent for fabric stores, 20 percent for discount stores, and 40 percent for direct sales. Of the total purchases made from either mill A or mill B, 20 percent of the bolts are unusable and thrown away. For every 1,000 bolts purchased from mill A, Central Fabric realizes a profit of P8,000; for every 1,000 bolts purchased from mill B, it realizes a profit of P6,000. The sales department forecasts that, at most, 1,600 bolts can be sold through fabric shops, 2,800 through discount stores, and 2,600 through direct mail in the coming year. Determine the most profitable numbers of bolts which Central Fabric should purchase from mills A and B using the graph method.
Answers
Using the graph method, Central Fabric should determine the most profitable numbers of bolts to purchase from mills A and B by considering profit calculations, supply and demand constraints, and plotting a profit graph.
To determine the most profitable numbers of bolts that Central Fabric should purchase from mills A and B using the graph method, we need to create a profit graph based on the given information.
Start by calculating the total available supply for each market channel:
Fabric Stores: (0.40 * Total Bolts from Mill A) + (0.20 * Total Bolts from Mill B)
Discount Stores: (0.10 * Total Bolts from Mill A) + (0.20 * Total Bolts from Mill B)
Direct Mail: (0.30 * Total Bolts from Mill A) + (0.40 * Total Bolts from Mill B)
Determine the maximum number of bolts that can be sold in each market channel:
Fabric Stores: 1,600 bolts
Discount Stores: 2,800 bolts
Direct Mail: 2,600 bolts
Calculate the profit for each combination of bolts purchased from mills A and B:
Profit from Mill A: (0.60 * Total Bolts from Mill A - 0.20 * Total Bolts from Mill A) * P8,000
Profit from Mill B: (0.80 * Total Bolts from Mill B - 0.20 * Total Bolts from Mill B) * P6,000
Plot the profit graph by considering different combinations of Total Bolts from Mill A and Total Bolts from Mill B, while taking into account the constraints of available supply and market demand.
Find the combination of Total Bolts from Mill A and Total Bolts from Mill B that maximizes the profit while satisfying the supply and demand constraints. This point on the graph represents the most profitable numbers of bolts to purchase from mills A and B.

how large a sample is needed in exercise 9.3 if we wish to be 95% confident that our sample mean will be within 0.0005 inch of the true mean?
Answers
We need a sample size of at least 1536 to be 95% confident that our sample mean will be within 0.0005 inches of the true mean.
To determine how large a sample is needed, we can use the formula for the margin of error:
To determine the required sample size for a 95% confidence interval with a specified margin of error, we'll use the following formula:
n = (Z * σ / E)^2
where:
- n is the sample size
- Z is the Z-score for a given confidence level (1.96 for a 95% confidence interval)
- σ is the population standard deviation
- E is the margin of error (0.0005 inches in this case)
The margin of error = Z-score * (standard deviation / square root of sample size)
Since we want to be 95% confident, the Z-score will be 1.96. We are given that we want the sample mean to be within 0.0005 inches of the true mean, so the margin of error will be 0.0005.
Thus, we can rearrange the formula to solve for the sample size:
Sample size = (Z-score)^2 * (standard deviation)^2 / (margin of error)^2
Since we do not know the population standard deviation, we can use the sample standard deviation as an estimate. Let's assume the sample standard deviation is 0.001 inch.
Plugging in the values, we get:
Sample size = (1.96)^2 * (0.001)^2 / (0.0005)^2
Sample size = 1536
Therefore, we need a sample size of at least 1536 to be 95% confident that our sample mean will be within 0.0005 inches of the true mean.

exactly two different integer solutions? Select all that apply.
Answers
Answer:
b = 10
b = 17
Step-by-step explanation:
Hello!
Usually, when you want two different integer solutions, you probably want the quadratic to be factorable.
So what we want to know is that b should be the sum of the factors in 16.
Factors of 16: 1, 2, 4, 8, 16
Factor pairs:
1, 162, 84, 4Factor Sums:
17108These are our possible b-values.
Check:
Let's try 17 first:
x² - 17x + 16 = 0(x - 16)(x - 1) = 0x = 16, x = 1Now 10:
x² - 10x + 16 = 0(x - 8)(x - 2) = 0x = 8, x = 2And finally, 8:
x² - 8x + 16 = 0(x - 4)(x - 4) = 0x = 4, x = 4Since x = 4 is a repetitive integer, we cannot use 8 as a value for b.
The answers are b = 10, and b = 17.
he average (arithmetic mean) of 100 measurements is 23, and the average of 50 additional measurements is 27 Quantity A uantity HB The average of the 150 measurements 25 Quantity A is greater Quantity B is greater
Answers
The average of the 150 measurements is 24.33, and Quantity B with a value of 25 is greater.
To compare the averages of the 150 measurements, let's calculate the total sum of all the measurements.
For the first set of 100 measurements with an average of 23, the total sum is 100 * 23 = 2300. For the second set of 50 measurements with an average of 27, the total sum is 50 * 27 = 1350.
To find the average of all 150 measurements, we need to find the total sum of all 150 measurements. Adding the two total sums calculated above, we have 2300 + 1350 = 3650.
To find the average, we divide the total sum by the total number of measurements: 3650 / 150 = 24.33.
Comparing the average of the 150 measurements to the individual averages A and B:
Quantity A: 24.33
Quantity B: 25
Since 25 is greater than 24.33, the answer is that Quantity B is greater.
