m AG
Answers
The measure of arc ACD is 180 degrees.
Given that AD and CG are diameters of circle B, we can determine the type and measure of arc ACD.
Since AD and CG are diameters, they divide the circle into four quadrants. Arc ACD is part of the circle that lies within one of these quadrants. If we imagine starting at point A and traveling along the circumference of the circle in the counterclockwise direction to point C, we traverse less than half of the circle, but more than a quarter. Hence, arc ACD is a minor arc.
Since AD is a diameter, arc ACD is a semicircle. A semicircle is an arc that measures exactly 180 degrees, which is half of a full circle.
Therefore, the measure of arc ACD is 180 degrees.

Question 291 ptHow many real solutions does the quadratic equation below have?y = 2? + 5x + 100 1 real solutionNo real solutions2 real solutionsInfinite number of real solutionsNexDrevious
Answers
The quadratic equation is:
\(y=2x^2+5x+10\)To find if the number of solutions, we use the discriminant of the equation. But first, we compare the given equation with the general quadratic equation:
\(y=ax^2+bx+c\)By comparison, we find the values of a, b, and c:
\(\begin{gathered} a=2 \\ b=5 \\ c=10 \end{gathered}\)Now, as we said previously, we have to use the discriminant to find the number of solutions. The discriminant is defined as follows:
\(D=b^2-4ac\)• If the value of D results to be equal to 0, there will be 1 real solution.
• If the value of D results to be greater than 0, there will be 2 real solutions.
• And if the value of D results to be less than 0, there will be no real solutions.
We substitute a, b and c into the discriminant formula:
\(D=5^2-4(2)(10)\)Solving the operations:
\(\begin{gathered} D=25-4(2)(10) \\ D=25-80 \\ D=-55 \end{gathered}\)As we can see, the value of D is less than 0 (D<0) which indicates that there will be no real solutions for this quadratic equation.
Answer: No real solutions

Have you ever looked closely at sound waves? They may look like random lines at first glance. But if you zoom in, you will see that they are very similar to graphs of trigonometric functions. Like trigonometric functions, they appear as oscillating waves with a measurable frequency and amplitude.
In music, each note has a specific frequency, measured in hertz. The units for hertz are cycles per second (1 ÷ sec), or sec-1. The most common note used for tuning an instrument is the A next to middle C. Pianists often call this note A4. This note has a frequency of 440 Hz. This means that the note A4 has 440 cycles in one second. Any musical note can be graphed using the function f(x) = sin (y × 2πx), where y is the frequency of the note and x is the time in seconds.
Part A Using this graphing tool, graph the function for note A4. Paste a copy of the graph below, keeping the default scale. What does it look like? Why does it appear like that?
Answers
The graph of the sine function f(x) = sin(400πx) is given by the image at the end of the answer.
How to graph the sine function?The sine function in this problem is defined as follows:
f(x) = sin (y × 2πx).
In which the relevant variable for the graph is the variable y, which is the number of cycles in a single second of the wave.
In this problem, it is states that the note has a frequency of 440 Hz, meaning that it has 440 cycles in one second, thus the equation is:
f(x) = sin (440 × 2πx).
f(x) = sin (880πx).
The function is not multiplied by any value, hence the amplitude is of 1, meaning that the function oscillates between 0 and 1, and also there is not any phase shift or vertical shift, meaning that it oscillates between -1 and 1 starting at the origin.

my cousin when in Vietnam was a personal banker for his Army buddies ... if they needed money mid-month he would give them $20 if you agreed to pay him $40 at month end on payday ... although he did not disclose his borrowing rate, what was the cost of money (APR) for his buddies who needed immediate gratification
Answers
The personal banker given lending arrangement, the APR for your cousin's buddies who borrowed $20 and repaid $40 at the end of the month would be 120%
The annual percentage rate (APR) for your cousin's lending arrangement, to make a few assumptions. That each lending transaction occurs on the first day of the month and is repaid on the last day of the same month. Based on these assumptions, calculate the effective APR as follows:
Calculate the interest charged for a $20 loan over one month:
Interest = $40 (repaid amount) - $20 (loaned amount) = $20
Divide the interest by the loan amount and multiply by 100 to get the monthly interest rate:
Monthly Interest Rate = (Interest / Loan Amount) ×100 = ($20 / $20) ×100 = 100%
Multiply the monthly interest rate by 12 to obtain the annual interest rate:
APR = Monthly Interest Rate ×12 = 100% ×12 = 120%

Which measure of central tendency is most appropriate when it is desired to minimize the effect of a few extreme (very high or very low) scores?group of answer choicesmedian
Answers
When it is required to minimize the effect of a few extreme scores, median is the measure of central tendency which is the most appropriate.
This is due to the fact that the median isn't influenced by extreme values, which means it is the middle value when the observations are ordered from least to greatest.There are several measures of central tendency, including the mode, median, and mean.
The most common measure is the mean, but it is greatly affected by the presence of a few very high or very low scores.To ensure that the mean isn't skewed too much by these scores, the median is a better choice. The median is the middle number in a data set when the observations are sorted from smallest to greatest.
In this way, if there are extremely high or low scores, they are not going to influence the median significantly as compared to the mean. Hence, we can say that the median is the most appropriate measure of central tendency when it is desired to minimize the effect of a few extreme scores.
The measure of central tendency that is most appropriate when it is desired to minimize the effect of a few extreme (very high or very low) scores is the median.

5.5 Invertible linear transformations (AR §8.3) 127. Is Transformation Invertible? Determine whether or not the given linear transformation is invertible. If it is invertible, compute its inverse. (a) T: R³ → R³ given by T(x, y, z) = = (x+z, x−y+z, y + 2z) (b) T: R² → R² given by T(x, y) = (3x + 2y, — 6x – 4y) (c) To : R² → R² an anticlockwise rotation around the origin through an angle of 0. (d) Tº : R² → R² a reflection in the line through the origin which forms an angle with the x-axis.
Answers
The inverse of Tº is also a reflection in the same line through the origin.
If a linear transformation satisfies these conditions, then it is invertible, and we can compute its inverse.
(a) T: R³ → R³ given by T(x, y, z) = (x+z, x−y+z, y + 2z)
To determine if T is invertible, we can check the rank of its matrix representation. We construct the matrix A that represents T, where each column corresponds to the images of the standard basis vectors.
A = |1 0 1|
|1 -1 1|
|0 1 2|
Calculating the rank of A, we find that rank(A) = 3, which is equal to the dimension of the domain R³. Therefore, T is invertible.
To compute the inverse of T, we can find the inverse of the matrix A. Using row operations, we can row-reduce A to the identity matrix I.
|1 0 1| |1 0 0|
|1 -1 1| → |0 1 0|
|0 1 2| |0 0 1|
The row-reduced form of A gives us the inverse of T:
T^(-1)(x, y, z) = (x, y, z) - (x + z, -y, -2z) = (-z, y, -z)
(b) T: R² → R² given by T(x, y) = (3x + 2y, -6x - 4y)
To determine if T is invertible, we again check the rank of its matrix representation:
A = |3 2|
|-6 -4|
Calculating the rank of A, we find that rank(A) = 1, which is less than the dimension of the domain R². Therefore, T is not invertible.
(c) To: R² → R² an anticlockwise rotation around the origin through an angle of θ.
Rotation transformations are invertible, as they preserve distances and angles. The inverse of a rotation transformation is another rotation with the opposite angle.
The inverse of To is a clockwise rotation around the origin through an angle of θ.
(d) Tº: R² → R² a reflection in the line through the origin that forms an angle with the x-axis.
Reflection transformations are also invertible. The inverse of a reflection transformation is the reflection itself.
The inverse of Tº is also a reflection in the same line through the origin.

a. The perimeter of the figure is 12x + 19
b. The perimeter of the figure if x = 4 is 67
Perimeter of a shapeFrom the question, we are to determine the perimeter of the given shape.
The perimeter of a given shape is the sum of all its sides
In the given diagram,
Perimeter of the figure = a + b + c + d
From the given information,
a = x + 7
b = 2x + 2
c = 8x
d = x + 10
Thus,
Perimeter of the figure = x + 7 + 2x + 2 + 8x + x + 10
Perimeter of the figure = x + 2x + 8x + x + 7 + 2 + 10
Perimeter of the figure = 12x + 19
∴ The perimeter of the figure is 12x + 19
b. We are to find the perimeter if x = 4
Perimeter of the figure = 12x + 19
Put the value of x into the equation
Perimeter of the figure = 12(4) + 19
Perimeter of the figure = 48 + 19
Perimeter of the figure = 67
