Coordinate system is a system that uses one or more numbers, or coordinates, to uniquely determine the position of the points or other geometric elements on a manifold such as Euclidean space.

To find the solution of this problem.

Firstly let us understand the parallel and perpendicular lines.

Parallel lines are the lines that do not intersect or meet each other at any point in a plane.

Two geometric objects are perpendicular if they intersect at a right angle. The condition of perpendicularity may be represented graphically using the perpendicular symbol, ⟂.

As we check all the options, WX is perpendicular to ZY and WX is parallel to AB.

The value of f(-2) is 1.

A function is a relation from a set A to a set B where the elements in set A only maps to one and only one image in set B. No elements in set A has more than one image in set B.

Given is a table of x values and f(x) values corresponding to those x.

When x = -6, f(x) = f(-6) = 3

When x = -2, f(x) = f(-2) = 1

When x = 0, f(x) = f(0) = 4

When x = 3, f(x) = f(3) = -2

So the value of f(-2) = 1.

Step-by-step explanation:

A. The total value of the loan with quarterly compounded interest is $52,400.

B. The total value of the loan with monthly compounded interest is $52,010.04

Part A: Total value of the loan with the quarterly compounded interest

To find the total value of the loan, we'll use the formula for compound interest:

A = P * (1 + r/n)^(nt)

Where:

A = final amount (loan + interest)

P = principal amount (initial loan) = $20,000

r = interest rate = 7% = 0.07

n = number of times compounded per year = 4 (quarterly)

t = number of years = 10

Plugging in the values, we get:

A = $20,000 * (1 + 0.07/4)^(4 * 10)

A = $20,000 * (1.0175)^40

A = $20,000 * 2.620075

A = $52,401.51

Rounding to the nearest hundred, the total value of the loan with quarterly compounded interest is $52,400.

Part B: Total value of the loan with the monthly compounded interest

To find the total value of the loan with monthly compounded interest, we'll use the same formula with a different value of n:

A = P * (1 + r/n)^(nt)

Where:

n = number of times compounded per year = 12 (monthly)

Plugging in the values, we get:

A = $20,000 * (1 + 0.07/12)^(12 * 10)

A = $20,000 * (1.005833)^120

A = $20,000 * 2.600502

A = $52,010.04

Rounding to the nearest hundredth, the total value of the loan with monthly compounded interest is $52,010.04

The difference between the two loans is $52,401.51 - $52,010.04 = $391.47

The difference between the two loans is due to the higher frequency of compounding in the monthly compounded interest loan. The interest is compounded more times per year, so the interest is accumulating on the interest more quickly, leading to a higher overall interest charge.

Answer:

[tex]y=\dfrac{1}{5}x+\dfrac{44}{5}[/tex]

Step-by-step explanation:

To write the equation of the line that passes through the points (1, 9) and (-4, 8), first find its slope.

To do this, substitute the given points into the slope formula:

[tex]\textsf{slope}\:(m)=\dfrac{y_2-y_1}{x_2-x_1}=\dfrac{8-9}{-4-1}=\dfrac{-1}{-5}=\dfrac{1}{5}[/tex]

To write the equation of the line, we can use the point-slope form of a linear equation.

[tex]\boxed{\begin{minipage}{5.8 cm}\underline{Point-slope form of a linear equation}\\\\$y-y_1=m(x-x_1)$\\\\where:\\ \phantom{ww}$\bullet$ $m$ is the slope. \\ \phantom{ww}$\bullet$ $(x_1,y_1)$ is a point on the line.\\\end{minipage}}[/tex]

Substitute the found slope m = 1/5 and point (1, 9) into the formula:

[tex]y-9=\dfrac{1}{5}(x-1)[/tex]

Simplify:

     [tex]y-9=\dfrac{1}{5}x-\dfrac{1}{5}[/tex]

[tex]y-9+9=\dfrac{1}{5}x-\dfrac{1}{5}+9[/tex]

There is no significant difference in interaction means.

The ANOVA table is used to test the null hypothesis that the means of two or more groups are equal. In this case, we are testing the means of four levels of Factor A and three levels of Factor B. The table shows the Sum of Squares (SS) for each source, the Mean Squares (MS), and the F-value for each source.

To determine if there is a significant difference in Factor A and Factor B means, we must calculate the critical values to test for equal means. We can do this by dividing the Mean Square (MS) of each factor by the Error Mean Square (MS Error). For Factor A, we have MS Factor A/MS Error = 60/400 = 0.15. For Factor B, we have MS Factor B/MS Error = 40/400 = 0.1. We can then compare these values to the critical value for a 0.05 significance level, which is 3.89. Since both of our values are below this critical value, we can conclude that there is no significant difference in Factor A and Factor B means.

Finally, to determine if there is a significant difference in interaction means, we must calculate the F-value for the Interaction source. This is done by dividing the Mean Square of the Interaction source (MS Interaction) by the Error Mean Square (MS Error). In this case, we have MS Interaction/MS Error = 110/400 = 0.275. We can then compare this value to the critical value for a 0.05 significance level, which is 3.89. Since our value is below this critical value, we can conclude that there is no significant difference in interaction means.

The circuit starts at the final AND gate. It has two inputs, one from an OR gate and one from a NOT gate.

The OR gate has two inputs, p and q. If either p or q is high (1), the OR gate will output a high signal. If both p and q are low (0), the OR gate will output a low signal. In this case, we only have the value of p, which is high, so the output from the OR gate is also high.

The NOT gate has one input, q. It inverts the signal, so if q is high (1), the NOT gate will output a low signal (0), and if q is low (0), the NOT gate will output a high signal (1). We don't know the value of q, so we don't know the output from the NOT gate.

Finally, the AND gate takes the outputs from the OR gate and the NOT gate as its inputs. If both inputs are high (1), the AND gate will output a high signal (1). If either input is low (0), the AND gate will output a low signal (0). Since we don't know the output from the NOT gate, we can't determine the output from the AND gate.
