find the bearing of b from a
Answer:
130° and 310°
Step-by-step explanation:
the bearing of A from B is the measure of the clockwise angle from a north line at B to A
the angle at B and A are same- side interior angles and sum to 180°
angle at B = 180° - 50° = 130°
the bearing of A from B is then 130°
the bearing of B from A is the measure of the clockwise angle from the north line at A to B
the complete angle about A = 360° then clockwise angle from north line at A to B is
360° - 50° = 310°
the bearing of B from A is 310°
A survey was given to a random sample of the residents of a town to determine whether they support a new plan to raise taxes in order to increase education spending. The survey reported a confidence interval that between 22% and 32% of the residents supports the plan. What is the margin of error on the survey? Do not write ± ± on the margin of error.
Answer:
[tex]\Huge \bold{\boxed{\boxed{\text{5\%}}}}[/tex]
Step-by-step explanation:
To calculate the margin of error for the survey, we need to use the formula:
[tex]\large \text{Margin of error} = \large \text{$\frac{\text{Range of values}}{2}$}[/tex]
The range of values is the difference between the upper and lower bounds of the interval. In this case, the lower bound is 22% and the upper bound is 32%, so the range of values is:
[tex]\large \text{Range of values = 32\% - 22\% = 10\%}[/tex]
Substituting this value into the formula, we get:
[tex]\large \text{Margin of error = $\frac{10\%}{2}$ = 5\%}[/tex]
Therefore, the margin of error on the survey is 5%.

The period of the function is 4π, and the amplitude is 2.
Given data ,
Let the function be represented as f ( x ) = y
Now , the value of f ( x ) is
y = 2sin ( 1/2 )x
To find the period and amplitude of the function y = 2sin((1/2)x), we can use the standard form of a sine function: y = Asin(Bx).
In this case, the amplitude (A) is 2.
The amplitude represents the maximum displacement from the midpoint of the sinusoidal function.
To find the period, we can use the formula:
Period = (2π) / |B|.
B = 1/2.
Period = (2π) / |1/2|
P = (2π) / (1/2) = 2π * 2/1 = 4π
Hence , the period of the function is 4π, and the amplitude is 2.

How could you estimate the extra cost per month of borrowing $50,000 for 30 years at 11% instead of 10%?
Borrowing $50,000 for 30 years at 11% instead of 10% would result in an extra cost of approximately $44.63 per month.
To estimate the extra cost per month of borrowing $50,000 for 30 years at 11% instead of 10%, you can follow these steps:
Calculate the monthly payment for each interest rate:
The formula to calculate the monthly payment for a fixed-rate loan is:
M = P * (r * (1 + r)^n) / ((1 + r)^n - 1)
Where:
M is the monthly payment,
P is the principal amount (loan amount),
r is the monthly interest rate (annual interest rate divided by 12),
n is the total number of monthly payments (number of years multiplied by 12).
Let's calculate the monthly payment at 10% interest rate first:
P = $50,000
r = 10% / 100 / 12 = 0.0083333 (monthly interest rate)
n = 30 years * 12 = 360 (total number of monthly payments)
M1 = $50,000 * (0.0083333 * (1 + 0.0083333)^360) / ((1 + 0.0083333)^360 - 1)
Calculate the monthly payment at 11% interest rate using the same formula:
P = $50,000
r = 11% / 100 / 12 = 0.0091667 (monthly interest rate)
n = 30 years * 12 = 360 (total number of monthly payments)
M2 = $50,000 * (0.0091667 * (1 + 0.0091667)^360) / ((1 + 0.0091667)^360 - 1)
Calculate the difference in monthly payments:
Extra cost per month = M2 - M1
Now let's perform the calculations:
M1 ≈ $446.92 (monthly payment at 10% interest rate)
M2 ≈ $491.55 (monthly payment at 11% interest rate)
Extra cost per month = $491.55 - $446.92 ≈ $44.63
Therefore, borrowing $50,000 for 30 years at 11% instead of 10% would result in an extra cost of approximately $44.63 per month.

A relation can map inputs to multiple outputs. It is a function when it maps each input to exactly one output. The set of all functions is a subset of the set of all relations.
If any x values are repeated, and the corresponding y values are different, then we have a relation and not a function.

The perimeter of the tri9angle MNO is P = 58 units.
How to find the perimeter of the triangle?The perimeter of the triangle is equal to the sum of the lengths of the sides, we know that:
OM = 23
NM = 18.4
To find the missing side we can use the similar triangle that we have next to it.
We can see that that OM is correspondent to LJ
Then if the scale factor between the triangles is K, we can write:
18.4 = 10*K
18.4/10 = K = 1.84
Now, NO is correspondent to KL, then:
NO = 1.84*9
NO = 16.6
Then the perimeter is:
P = 16.6 + 23 + 18.4

Precalc question below.
The number of additional copies you could ship by ordering 128 instead of 127 copies is 0 copies.
We have,
To determine the number of additional copies you could ship if you ordered 128 copies instead of 127 copies, we need to compare the costs of ordering each quantity using the given function C(n).
For n = 127:
C(127) = $6.91 x 127 = $878.57
For n = 128:
C(128) = $5.16 x 128 = $660.48
By subtracting the cost of ordering 127 copies from the cost of ordering 128 copies, we can determine the cost difference:
Cost difference = C(128) - C(127)
= $660.48 - $878.57
= -$218.09
Since the cost difference is negative, it means that ordering 128 copies is cheaper than ordering 127 copies.
However, the question asks for the number of additional copies, so we need to consider the whole number of copies.
Rounding down to the nearest whole copy, the number of additional copies you could ship by ordering 128 instead of 127 copies is 0 copies.
Thus,
The number of additional copies you could ship by ordering 128 instead of 127 copies is 0 copies.

Given that,
The value of China's exports of automobiles and parts (in billions of dollars) is approximately,
f(x) = 1.8208 e^(0.33872x)
We have to find the value of x, when f(x) = $11.2 billion
11.2 = 1.8208 e^(0.33872x)
6.15 = e^(0.33872x)
Taking logarithms on both sides,
ln (6.15) = 0.33872x ln (e)
ln (6.15) = 0.33872x

Se está construyendo una escalera que inicia a 4.10 m para alcanzar una altura de 2.35 m calcular la longitud de la escalera y cual es su ángulo de elevación 0 .
The length of the ladder is 4.72 meters and its angle of elevation is 30.4 degrees.
Using the Pythagorean theorem:
Length of the ladder = √(height² + horizontal distance²)
= √(2.35² + 4.10²)
= √(5.5225 + 16.81)
= √22.3325
≈ 4.72 meters
To calculate the angle of elevation (θ), we can use the trigonometric function sine:
sin(θ) = height / length of the ladder
θ = arcsin(height / length of the ladder)
θ = arcsin(2.35 / 4.72)
θ ≈ 30.4 degrees

We have,
Data can be described by a single number using summary statistics. Summary statistics provide a concise representation of the main characteristics of a dataset.
Commonly used summary statistics include measures such as the mean, median, mode, range, variance, and standard deviation.
These single numbers provide insights into different aspects of the data, such as the central tendency, variability, or distribution.
Tables and graphs are effective tools for representing data and answering questions because they provide a visual representation that helps to organize and understand the information.
Tables present data in a structured format, typically using rows and columns, which allows for easy comparison and analysis.
They can display raw data, summary statistics, or both.
Graphs, on the other hand, use visual elements to represent data in a more intuitive and visual manner.
Different types of graphs can be used depending on the nature of the data and the question at hand.
For example, bar graphs can be used to compare categories or discrete data, line graphs can show trends over time, and scatter plots can display the relationship between two variables.
Tables and graphs help to answer questions about data by providing a clear and organized presentation.
They allow us to observe patterns, trends, and relationships, making it easier to draw conclusions and make informed decisions.
Visually representing data, tables, and graphs enhances our ability to analyze and interpret complex information quickly and effectively.
