Step-by-step explanation:
Complex numbers:
The most important relation that involves complex numbers is given by:
[tex]i^2 = -1[/tex]
Solving a quadratic equation:
Given a second order polynomial expressed by the following equation:
[tex]ax^{2} + bx + c, a\neq0[/tex].
This polynomial has roots [tex]x_{1}, x_{2}[/tex] such that [tex]ax^{2} + bx + c = a(x - x_{1})*(x - x_{2})[/tex], given by the following formulas:
[tex]x_{1} = \frac{-b + \sqrt{\bigtriangleup}}{2*a}[/tex]
[tex]x_{2} = \frac{-b - \sqrt{\bigtriangleup}}{2*a}[/tex]
[tex]\bigtriangleup = b^{2} - 4ac[/tex]
In this question:
The solutions are:
[tex]x_1 = 1 - 3i, x_2 = 1 + 3i[/tex]
We have to find the polynomial. All option have [tex]a = 1[/tex]. So
[tex](x - (1 - 3i))(x - (1 + 3i)) = x^2 - x(1 + 3i) - x(1 - 3i) + (1 - 3i)(1 + 3i) = x^2 - x -3ix - x + 3ix + 1^2 - (3i^2) = x^2 - 2x + 1 - 9i^2 = x^2 - 2x + 1 - 9(-1) = x^2 - 2x + 10[/tex]
The correct answer is given by option b.

Functions A,B and C are linear functions. Some values of function A are shown in the table. Function B has y-intercept of (3,0) and a x-intercept of (5,0). Function C is defined by the equation y=3x+1.
HERES THE TABLE
X. 3,5,6
Y. 3,7,9.
Create equations for each of the 3 functions given above?
Order the linear functions based on rate of change from least to greatest?
Answer:
In order of increasing slope:
B: y = 0
A: y = 2x-3
C: y = 3x+1
Step-by-step explanation:
(3,3), (5,7), and (6,9) are points on line A.
Use the coordinates of two of the points to find the slope of A.
Δy =7-9 = -2
Δx =5-6 = -1
Slope = Δy/Δx = 2
Equation for line of slope 2 that passes through (3,3):
y-3 = 2(x-3)
y = 2x-3
(3,0) and (5,0) are points on line B. They are horizontally aligned, so the equation for line B is y=0. Slope = 0.
You were given the equation for C: y = 3x+1. Slope = 3
In order of increasing slope:
B: y = 0
A: y = 2x-3
C: y = 3x+1

Drew is buying a $325,000 house. He will put a 4.5% down payment and finance the
rest of the price with a mortgage loan. What is the mortgage loan amount? Round your
answer to the nearest thousand
$310,000
$300.000
0 $311.000
$275,000
Answer:
$311,000
Step-by-step explanation:
Original cost of house = $325,000
Mark down percent = 4.5%
Markdown price = 4.5% * 325000
Markdown price = 0.045*325000
Markdown price = $14,625
Mortgage loan amount now = $325,000 - $14,625
Mortgage loan amount now = $310,375
Mortgage loan amount now tom the nearest thousand is $311,000
1. Find the distance of a line segment with endpoints G (4,9) and H (7,1).

about 3.6 units
about 7.8 units
Answer:
a) d = 8.5 units
The distance of a line segment with end points
d = 8.5 units
Step-by-step explanation:
Step(i):-
Given points are G(4,9) and H( 7,1)
By using distance formula
G H = [tex]\sqrt{x_{2}-x_{1} )^{2} +(y_{2} -y_{1} )^{2} }[/tex]
Step(ii):-
[tex]d = \sqrt{7-4 )^{2} +(1-9 )^{2} }[/tex]
d = [tex]\sqrt{3)^{2} +(-8 )^{2} } = \sqrt{9+64} = \sqrt{73}[/tex]
d = 8.5 units

Which is an equation in point slope form for the given point and slope? Point: (-3,7) Slope: 4
Answer:
y-7=4x(x+3)
Step-by-step explanation:
(The 4x is 4 times ...)
Answer:
[tex]y -7 = 4(x+3)[/tex]
Step-by-step explanation:
Point-slope form is in the format of [tex]y-y_1 = m (x-x_1)[/tex]. When knowing a line's slope and a point it passes through, you can write an equation in that format. The [tex]m[/tex], [tex]x_1[/tex], and [tex]y_1[/tex] must be substituted for with real values.
The [tex]m[/tex] represents the slope, thus substitute 4 for [tex]m[/tex]. [tex]x_1[/tex] represents the x-value of one point the line passes through, while [tex]y_1[/tex] represents that same point's y-value. The line passes through (-3, 7), so substitute -3 for [tex]x_1[/tex] and 7 for [tex]y_1[/tex]. This gives the following answer and equation:
[tex]y-(7) = 4(x-(-3))\\y -7 = 4(x+3)[/tex]
Lines C and D are represented by the equations given below: Line C: y = x + 6 Line D: y = 3x + 2 Which of these shows the solution to the system of equations and explains why? (10 points)
A. (2, 8), because both lines pass through this point
B. (2, 8), because the point does not lie on any axis
C. (4, 14), because one of the lines passes through this point
D. (4, 14), because the point lies between the two axes
Answer:
C) y = x + 6
D) y = 3x + 2 We multiply C) by -1
C) -y = -x -6
D) y = 3x + 2
0 = 2x -4
x = 2
y = 8

Function c is defined by the equation c(n)=50+4n. It gives the monthly cost, in dollars, of visiting a gym as a function of the number of visits, n. What is the inverse function.
Answer:
(x - 50 / 4) = y
Step-by-step explanation:
On photo
To find the inverse function, you will have to write n in terms of c (which means number of visits as function of monthly cost).
The inverse function would be:
[tex]n = \dfrac{c-50}{4}[/tex]
Given that:c(n) = 50 + 4nc is monthly cost in dollars, of visiting a gym.n is the number of visits.To find:Inverse function of given function.
What is inverse function and when is it possible to find such function?The inverse function of f is a function of f which can remove the effect of f on its input.
Inverse is only possible if the function f is bijective (one to one correspondence, which means one input to one output uniquely and one output is connected to only one input by mapping f)
Since the given function is a linear function and not a vertical line, thus, one input n uniquely maps to one output cost and one cost uniquely is obtained by one and only one value of n.
Finding the inverse function of c(n) = 50 + 4n:[tex]cost = 50 + 4n\\ 4n = cost - 50\\\\ n = \dfrac{\text{c - 50}}{4} \text{\: (assuming cost to be denoted by c)}[/tex]
Thus, we have the inverse function of given function as:
[tex]n = \dfrac{c-50}{4}[/tex]

A squar has an area of 64cm2 find the perimeter of the square
Answer: 32 cm
Step-by-step explanation:
Answer:
All of the sides of the square are 8 cm. So the prementer would be 32 cms
Step-by-step explanation:
To find the sides of the square, you got to think what x what = 64. This shows you that 8 x 8 is 64. and since it is a square, all of the sides are the same. So 8+8+8+8 = 32 or you can do 8 x 4 = 32
