NEED HELP ASAP The equation of line a is: -x + 4y = 32
How do theses equations compare to line a?
y=1/4x + 1
-4x+y=-8
4x+y=-3
y = 1/4x + 1 is parallel to line a
-4x + y = -8 is neither parallel nor perpendicular to line a
4x + y = -3 is perpendicular to line a
Parallel and Perpendicular linesFrom the question, we are to determine how the given equations compare to line a.
From the given information,
Line a is -x + 4y = 32
First, we will determine the slope of line a
To do this, we will compare the equation to the slope-intercept form of a line
The slope-intercept form of a line is
y = mx + b
Where m is the slope
and b is the y-intercept
Writing -x + 4y = 32 in the slope-intercept form
-x + 4y = 32
4y = x + 32
Divide through by
y = 1/4 x + 8
By comparison, the slope of line a is 1/4
NOTE: If two lines are parallel, their slopes will be equal
and
If two lines are perpendicular, their slopes will be the negative reciprocal of each other
Now, we will determine the slopes of each of the lines
For y = 1/4x + 1
By comparing with the slope-intercept form of a line, y = mx + b
The slope of the line is 1/4
Thus, the line is parallel to line a
For -4x+y=-8
Rewrite in the slope-intercept form of a line
-4x + y = -8
y = 4x - 8
By comparing with the slope-intercept form of a line, y = mx + b
The slope of the line is 4
4 is not equal to 1/4 and 4 is not the negative reciprocal of 1/4.
Thus, the line is neither parallel nor perpendicular to line a.
For 4x+y=-3
Rewrite in the slope-intercept form of a line
4x + y = -3
y = -4x - 3
By comparing with the slope-intercept of a line, y = mx + b
The slope of the line is -4
-4 is the negative reciprocal of 1/4.
Thus, the line is perpendicular to line a.

Late one night a burglar got into one of the vaults in Fort Knox and he stole a big sack of gold coins. On his way out, he was stopped by one of the guards who saw him stealing the bag . Fortunately for him, the burglar was able to negotiate a deal with the guard and offered him half the money he had taken, plus an extra $2,000 thrown in. Just as he was walking away, thinking he had gotten away he was stopped by a second guard who took the same bribe: Half the money with an extra $2000 thrown in. Just as he was about to leave , he was stopped by a third guard who let him go only after receiving half of all the burglar had left with $ 2,000 extra thrown in. By the time he left he had mixed emotions. After all he did leave with $9,000 more than he had when he arrived and he was able to escape. But he thought of all the money he left behind. How much did he steal in the first place?
Answer:
We can start by using algebra to represent the information given in the problem. Let x be the amount of money the burglar stole initially.
According to the problem, when the burglar gave half of the money plus $2,000 to the first guard, he was left with x/2 + 2000.
When he gave the same amount to the second guard, he was left with (x/2 + 2000)/2 + 2000.
And when he gave the same amount to the third guard, he was left with ((x/2 + 2000)/2 + 2000)/2 + 2000.
But we know that he left with $9,000 more than he had when he arrived, So we can say:
((x/2 + 2000)/2 + 2000)/2 + 2000 = x + 9000
We can now solve for x:
x = (900022*2 - 6000)/3
x = 36000/3
x = 12000
So the burglar stole $12000 in the first place.

Answer: 384 ft^2
Step-by-step explanation:
Like it said set up a proportional equation and solve for dimensions in feets.
The scale factor saids 0.75 in = 2 ft
And the dimensions are 6 in by 9 in
Now using the scale solve for how many feets will make 6 inches and how many feets will make 9 inches .
\(\frac{0.75}{6} = \frac{2}{x}\) Solve by cross multiplying
0.75x = 12
x = 16
\(\frac{0.75}{9} = \frac{2}{x}\) Cross multiply
0.75x = 18
x = 24
Now since we know the new dimensions are 16ft by 24ft then we will multiply them together to find the area .
16 * 24 = 384 ft^2
The graph of a sinusoidal function intersects its midline at ( 0 , − 6 ) (0,−6)left parenthesis, 0, comma, minus, 6, right parenthesis and then has a minimum point at ( 2.5 , − 9 ) (2.5,−9)left parenthesis, 2, point, 5, comma, minus, 9, right parenthesis. Write the formula of the function, where � xx is entered in radians. � ( � ) = f(x)=f, left parenthesis, x, right parenthesis, equals
The formula of the function, where x is entered in radians is y = -3sin(πx/5) -6
What is the sinusoidal function?The key components: amplitude, period, phase shift, and vertical shift.
Amplitude is the distance between the midline and max/min points. Midline at (0, -6), so distance to min point (2.5, -9) is 3. Amplitude: 3.
Vertical shift: Displacement along y-axis. Midline at y = -6, vertical shift is -6. Period: distance between max/min points. Graph intersects midline at (0, -6) and minimum point at (2.5, -9). Period is 5 (2 * 2.5). Freq: Reciprocal of period, 1/5.
Phase shift: Horizontal shift of graph. Graph intersects midline at x=0, no phase shift.
Hence:
Amplitude: 3Vertical shift: -6Period: 5Frequency: 1/5Phase shift: 0The general form of the sinusoidal function is y = A sin (B(x-C)) + D
So, Substituting the known values into the general formula:
y = 3 x sin((1/5)x - 0) - 6
Hence: Simplifying it will be:
y = 3 x sin(πx/5) - 6
Then, the formula of the function, where x is entered in radians, is: y = -3sin(πx/5) - 6
Based on the image attached, the first given point is one that informs one that the function is a sine (not a cosine) function, and that it is one that has its offset as -6.
Also, the second given point is one that informs you of the first peak is at x=2.5, hence the argument of the sine function is π/2 if x=2.5: (πx/5).
Based on the fact that the peak is 3 units smaller than the midline, the amplitude is said to be -3.
Therefore the formula for the function is seen as: y = -3·sin(πx/5) -6

Step-by-step explanation:
using the tangent ratio in the right triangle
tan A = \(\frac{opposite}{adjacent}\) = \(\frac{BC}{AB}\) = \(\frac{5}{11}\) , then
∠ A = \(tan^{-1}\) ( \(\frac{5}{11}\) ) ≈ 24.4° ( to 1 decimal place )
tan C = \(\frac{opposite}{adjacent}\) = \(\frac{AB}{BC}\) = \(\frac{11}{5}\) , then
∠ C = \(tan^{-1}\) ( \(\frac{11}{5}\) ) ≈ 65.6° ( to 1 decimal place )
using Pythagoras' identity in the right triangle
the square on the hypotenuse is equal to the sum of the squares on the other two sides, that is
AC² = AB² + BC² = 11² + 5² = 121 + 25 = 146 ( take square root of both sides )
AC = \(\sqrt{146}\) ≈ 12.08 ( to 2 decimal places )

What is vertical stretch factor?The vertical stretch factor is a term used in mathematics to describe the transformation that changes the height of a graph while leaving the horizontal axis unchanged. In other words, it's a factor by which the y-values of a function are multiplied to produce a new, stretched or compressed version of the original graph.
The stretch factor is usually represented by the symbol "k". For example, if the equation of a function is y = f(x), then the equation of its vertically stretched image would be y = k * f(x). A positive value of k stretches the graph upward, while a negative value of k compresses the graph downward. If k > 1, the graph is stretched vertically; if 0 < k < 1, the graph is compressed vertically; if k = 1, the graph remains unchanged.

Un bloque de vidrio flint tiene un espesor de 4 cm, ¿qué espesor aparenta tener cuando se le ve desde arriba?
Answer: El índice de refracción del vidrio flint es mayor que el del aire. Cuando la luz pasa de un medio con un índice de refracción menor (como el aire) a un medio con un índice de refracción mayor (como el vidrio), experimenta un cambio de dirección. Este fenómeno se conoce como refracción.
Cuando observamos el bloque de vidrio flint desde arriba, la luz que proviene del bloque sufre refracción al pasar del vidrio al aire. Debido a la refracción, los rayos de luz se desvían y parecen venir de una posición más alta dentro del vidrio de lo que realmente están. Esto crea una ilusión óptica que hace que el espesor aparente del bloque de vidrio se vea más delgado de lo que realmente es.
La cantidad exacta de adelgazamiento aparente depende del ángulo de incidencia de la luz y de los índices de refracción del vidrio y el aire. Sin más información, no es posible determinar el espesor aparente específico del bloque de vidrio flint cuando se ve desde arriba.

What is the slope of the line whose equation is 2x – 4y = 9?
a) 1
2
c) 2
d) 3
solotion
Answer:
m = 1/2
Step-by-step explanation:
The given equation of line is :
2x – 4y = 9 ..(1)
We need to find the slope of the line. The general equation of a line is given by :
y = mx + c ..(2)
Where
m is the slope of line
Equation (1) can be rearranged as follow :
-4y = 9-2x
4y = -9+2x
or
4y = 2x-9
Divide both sides by 4.
\(\dfrac{4y}{4} = \dfrac{2x}{4}-\dfrac{9}{4}\\\\y=\dfrac{1}{2}x+(\dfrac{-9}{4})\) ..(3)
Now comparing equation (2) and (3) we get :
\(m=\dfrac{1}{2}\)
So, the slope of the line is 1/2.
A marketing researcher must determine how many telephone numbers she needs to order from a sample provider to complete a survey of ATM users. The goal is to complete 400 interviews with ATM users. From past experience, she estimates that 70 percent of the phone numbers provided will be working phone numbers. The estimated incidence rate (percentage of people contacted who are ATM users) is 45 percent. Finally, she estimates from previous surveys that 37 percent of the people contacted will agree to complete the survey. How many telephone numbers should she order to complete the 400 interviews
Answer:
the required number of telephone orders to complete the 400 interviews is 3433
Step-by-step explanation:
Given the data in the question;
Let us represent the telephone numbers the researcher orders to complete the 400 interviews with Y.
Thus, The working phone numbers = 70% × Y
Now, number of ATM users = 45% × The working ph0ne numbers
⇒ 45% × ( 70% × Y )
number of ATM users = 0.45 × 0.70 × Y = 0.315Y
Thus; Number of people contacted that agrees to complete the survey will be;
⇒ 37% × number of ATM users
⇒ 0.37 × 0.315Y = 0.11655Y
so, since the researcher needs at least 400 interviews
Hence;
0.11655Y ≥ 400
Y ≥ 400 / 0.11655
Y ≥ 3432.0034 ≈ 3433
Therefore, the required number of telephone orders to complete the 400 interviews is 3433
