Which graph shows a plot of the complex number i − 2?
Given:
Complex number: i − 2?
i - 2 is \(-2 + i\) in standard form. So, the point is 2 left and 1 up from the origin and the graph that shows a plot of the complex number i – 2 is the second graph. Please see attached image for the graph.
To add, expressing a number in the form a + bi, whereas the real numbers are b an a, while i is the imaginary unit (which satisfies the equation i2 = −1) is called a complex number. a is called the real part of the complex number, and b is called the imaginary part In the given expression.
The demand for a new electric guitar causes a music store to increase the price of the guitar by 45%. If the guitar originally costs $320, what is the new price of the guitar?
Answer:
The new price of the guitar would be $464.00
Step-by-step explanation:
The original price of the guitar = $320
The music store increased the price of guitar by = 45%
First we calculate 45% of the 320 and then add it to the original price.
The new price of the guitar = 320 + ( 45% × 320 )
= 320 + ( 0.45 × 320 )
= 320 + 144
= $464
The new price of the guitar would be $464.00
One US dollar is currently worth 0.79 euro (€). If you exchange $522 for euros, how many euros will you have?
If you exchange $522 for euros, the number of euros you would have is equal to 412.38 euros (€).
What is a direct proportion?In Mathematics and Geometry, a direct proportion is a mathematical equation which is typically used to represent the equality of two (2) ratios.
Based on the information provided, we have the following exchange rate:
1 US dollar = 0.79 euro (€).
522 US dollar = X euro (€).
By cross-multiplying, we have the following:
X = 0.79 euro (€) × 522 US dollar
X = 412.38 euros (€).

How is a tangent different from a chord? Explain.
The main difference between tangent and chord is that the tangent touches the curve at only one point whereas the chord touches the curve at two points.
Chord:
A chord is the line segment joining two points on a curve. The term is often used to describe a line segment whose ends lie on a circle.Tangent:
The tangent line (or simply tangent) to a plane curve at a given point is the straight line that "just touches" the curve.The tangent makes an angle of 90 degree with the radius of circle at the point of contact.From above definitions of Chord and Tangent , we say that chord touches the curve at two points where as Tangent touches the curve at only one point .
For more details on chord and tangent follow the link:
https://brainly.com/question/2447567
A tangent is a line that touches a circle at only one point and is perpendicular to the radius at the point of contact, while a chord is a line segment with both endpoints on the circle.
A tangent and a chord are lines that relate to the curve of a circle, but they have distinct differences. A tangent is a line that touches a circle at exactly one point, and at this point of contact, it is perpendicular to the radius of the circle, which is called the axis in this context. In sharp contrast, a chord is a line segment whose endpoints both lie on the circle. When constructing the perpendicular from the midpoint of a chord, you are drawing an axis. For tangents, the perpendicular erected from the point of contact with the circle is also an axis.
This shows that the tangent is unique in that it has a "no-cut" property; it is the only line that will touch the circle at that single point without cutting through it. When looking at the slope of curves, the slope of the tangent line at the point of contact represents the exact slope of the curve at that point. The differentiation process in mathematics is used to find this slope of the tangent, which is important for understanding the rate of change at a specific point on a curve.

Final answer:
The algebraic expression with a variable 'x' in the numerator and '4' in the denominator translates to the verbal expression 'The quotient of some number and four', indicating a division of 'x' by 4.
Explanation:
The algebraic expression given is a fraction with variable x in the numerator and 4 in the denominator. This expression can be translated into a verbal expression as "The quotient of some number and four". It's important to understand each term used in this expression:
Quotient refers to the result of division.
Some number refers to an unspecified or unknown quantity, which is represented by x in this context.
The number 4 is the divisor in this expression.
Therefore, when we talk about the quotient of some number and four, we are referring to dividing an unknown quantity (x) by four (4).
Find the values of x and y that make k || j and
m || n.
The values of x and y are 80 and 70 respectively which make k parallel to j and m parallel to n.
Geometrically, parallel means two or more lines, line segments, or rays that never intersect or cross each other, it doesn't matter how far they are extended. Parallel lines always maintain the same distance between them and remain equidistant at every point.
The sum of two adjacent angles is [tex]180^o[/tex],
therefore,
[tex](x-30)^o+(x+50)^o= 180^o[/tex]
2x +20 = 180
2x = 180 - 20
2x = 160
[tex]\frac{2x}{2} = \frac{160}{2}[/tex]
x = 80.
Again, as the sum of two adjacent angles is [tex]180^o[/tex],
[tex](x-30)^o+y^o= 180^o[/tex]
x + y = 180 + 30
Substitute value of x,
80 + y = 150
y = 150 - 80
y = 70.
Thus, x = 80 and y = 70 are the values for which k is parallel to j and m is parallel to n.
