Tommy is buying a home, its purchase price is $200,000. She has to put
down 5%, with an APR of 6.4%. What will her monthly payment be.
The required monthly payment for 6.4% of interest is $16846.6.
What is interest?Interest is the cost of borrowing money or the fee you charge to lend it. Most frequently, interest is shown as an annual percentage of the loan amount. The interest rate for the loan is denoted by this proportion.
According to question:We have,
Purchasing price = $200,000
Down payment = 5% of $200,000
= $10000
Remaining Amount = $190000
Interest of one year = 6.4%
Amount of interest = 6.4% of $190000
Amount of interest = $12160
Total amount = f $190000 + $12160
Total amount = $202160
Monthly payment = $16846.6
Thus, required monthly payment is $16846.6.

Consider the equation:
4(2 + px) = 12x
For what value of p does the equation have no solution?
A 1
B. 3
C 12
D. 48
Answer:
p = 3
Step-by-step explanation:
Given
4(2 + px) = 12x
If the coefficient of the x- term is the same on both sides of the equation, it will have no solution.
Distributing gives
8 + 4px = 12x ( equate the coefficients of the x- term )
4p = 12 ( divide both sides by 4 )
p = 3
The value of p when the equation has no solution will be 3. Then the correct option is B.

the peak in a normal curve appears directly above _______.
The peak in a normal curve appears directly above the mean, which is the average value of the data set. The normal curve, also known as the Gaussian distribution, is a symmetrical bell-shaped curve that represents the distribution of data in a population.
The mean is the point of highest probability in the distribution, and as such, the peak of the curve appears directly above it. The normal curve is commonly used in statistical analysis, as it allows for the calculation of probabilities and the identification of outliers within a data set. Understanding the location of the peak in relation to the mean is key to interpreting and utilizing the information provided by a normal curve.
The peak in a normal curve appears directly above the mean. In a normal distribution, the mean, median, and mode are all equal and are located at the center of the curve. This is the highest point on the curve, representing the most frequent value in the data set. The normal curve is symmetric, with the tails extending indefinitely in both directions. As you move away from the mean, the frequency of values decreases, following the bell-shaped curve pattern. In summary, the peak in a normal curve represents the central tendency of the data, appearing directly above the mean value.

what is the time complexity of finding a source in a directed graph or to determine such a source does not exist if the graph is represented by its adjacency matrix?
The time complexity of finding a source in a directed graph or determining such a source does not exist if the graph is represented by its adjacency matrix is V².
If a directed graph is represented by an adjacency matrix, the following approach may be used to either discover a source inside the network or establish that there isn't one:
Create an array named inDegree and fill it with the in-degree of each graph vertex (i.e., the number of incoming edges for each vertex).Using in-degree 0, search the vertex by traversing the inDegree array. There is no one source in the network if there are several vertices with in-degree 0.If an in-degree 0 vertex is discovered, we then look to see if there is a path connecting it to every other vertex in the graph.This approach has an O(V²) time complexity, where V is the number of graph vertices. This is due to the fact that it takes O(V²) time to traverse the whole adjacency matrix in order to determine each vertex's in-degree. The next step requires traversing the inDegree array in O(V) time in order to discover a vertex with in-degree 0. In the worst scenario, it takes O(V²) time to determine if there is a path connecting this vertex to every other vertex.

find the circumfernce of the circle Use 3.14 for
Answer: To find the circumference of a circle, use the formula, 2(3.14)(r) (r is the radius, and if it gives the diameter, divide the diameter by 2 [to get the radius]). To find the actual circumference of the circle, multiply 2 and 3.14, becoming 6.28. Then, multiply 6.28 by whatever the radius is. Hope you find this useful!
Note: I am going based on no given picture and measurements of the circle, the other person that answered is, also, correct, and you could multiply the first two numbers (and then multiply the other number by the answer you received) OR multiply the first number, being 2, by the radius (and multiply that answer by the number of 3.14). For an example, the radius=10 units. You could either do 2x10=20, then 20x3.14=62.8 units^2 or multiply 3.14x2=6.28 units, then multiply 6.28 by 10, which is 62.8 units^2.

Step-by-step explanation:
the three lines shown in the diagram below intersect at the same point. the measures of some of the angles in degrees are given as 3(x-2),(3/5y),12,42
At point P, all three angles have a measure of is 180 degrees.
What are lines?Lines are basic geometric figures made up of groups of points that extend indefinitely in opposite directions.
The only dimension they have is length; neither breadth nor thickness are present. They can be straight or curved.
The total of the angles at the place where the three lines intersect is 180 degrees. That point is designated P.
The first line's angle can be expressed as 3(x-2) degrees.
(3/5)y degrees can be used to denote the angle that the second line creates.
Twelve degrees can be used to illustrate the angle that the third line creates.
The two expressions can be set to be equal to one another:
3(x-2) = (3/5)y
When we simplify this equation, we obtain:
15(x-2) = 3y
5(x-2) = y
Let's now think about the triangle the three lines created. We are aware that a triangle's total angles equal 180 degrees. Therefore:
Angle A + Angle P + Angle B = 180 degrees
The following measures can be used to express angles:
Angle A = 3(x-2) + (3/5)y
Angle P = 42
Angle B = 12
When we enter these expressions into the formula, we obtain:
(3(x-2) + (3/5)y) + 42 + 12 = 180
Using the previous equation we discovered for y to simplify this equation:
3x - 6 + (3/5)(5(x-2)) + 54 = 180
3x - 6 + 3(x-2) + 54 = 180
6x + 42 = 180
6x = 138
x = 23
We can now apply the equation we discovered before for y:
5(x-2) = y
5(23-2) = y
5(21) = y
y = 105
As a result, the first line's angle is as follows:
3(x-2) = 3(23-2) = 63 °
The second line's angle is as follows:
(3/5)y = (3/5)(105) = 63°
Additionally, the third line's angle is 12°.

Answer:
y +3 = -x -6
See the attachment for a graph
Step-by-step explanation:
You want the point-slope equation and graph of the line through point (-6, -3) with slope -1.
Point-slope equationThe point-slope equation of a line through point (h, k) with slope m is ...
y -k = m(x -h)
You have (h, k) = (-6, -3) and m = -1, so the equation is ...
y -(-3) = (-1)(x -(-6))
y +3 = -x -6 . . . . . point slope equation
Graph
The slope is the ratio of "rise" to "run" for the line. A slope of -1 means the "rise" is -1 for each 1 unit to the right. That is, (-6+1, -3-1) = (-5, -4) will be another point on the line, in addition to the one given.

a variable that cannot be measured in numerical terms is called group of answer choices a nonmeasurable random variable a constant variable a dependent variable a qualitative variable
A variable that cannot be measured in numerical terms is called a qualitative variable. Qualitative variables, also known as categorical variables, are used to describe characteristics or attributes of a population or a sample.
They are typically divided into nominal variables, which do not have a natural order, and ordinal variables, which have a natural order.
Qualitative variables are often used in surveys, polls, and experiments to gather information about people's opinions, preferences, and behaviors. Examples of qualitative variables include gender, race, religion, political affiliation, and educational level. These variables are important in many fields, including sociology, psychology, marketing, and political science. Qualitative data can be analyzed using various statistical techniques, including contingency tables, chi-square tests, and logistic regression.
