1. How do you define quadratic equations?
Answer:
[tex]ax^{2} +bx+c^{2}=0[/tex]
Step-by-step explanation:
A quadratic equation is a equation that takes the form: [tex]ax^{2} +bx+c^{2} = 0[/tex]
Ex. Using our definition of quadratic equations, [tex]ax^{2} +bx+c^{2}=0[/tex],
We can set a = 2, b = 1, c = 6:
[tex]2x^{2} +x+6^{2}=0[/tex]
[tex]2x^{2} +x+36=0[/tex]
Which can then be solved (if you are trying to solve it) as:
[tex](2x+9)(x-8)=0[/tex]
[tex]x=\frac{9}{2}, 8[/tex]

Graph a parabola whose vertex is at (3,5)(3,5)left parenthesis, 3, comma, 5, right parenthesis with yyy-intercept at y=1y=1y, equals, 1.
Using the given information we found that the equation of the parabola is:
y = (-4/9)*(x - 3)^2 + 5
And its graph is below.
How to get the equation of the parabola?
For a parabola with vertex (h, k), the equation is:
y = a*(x - h)^2 + k
Here the vertex is (3, 5), so the equation is:
y = a*(x - 3)^2 + 5
And the y-intercept is y = 1, this means that:
1 = a*(0 - 3)^2 + 5
1 = a*9 + 5
1 - 5 = a*9
-4/9 = a
So the parabola is:
y = (-4/9)*(x - 3)^2 + 5
And its graph is below.

Find the midpoint of the segment with the following endpoints.
(8,4) and (2,7)
Answer: The midpoint is (5,5.5)
Step-by-step explanation:
Adding X1 And X2 equals 10. Then the x variables have to be divided which is 10 divided 2 equals 5, the 5 represents the x value of the x part of midpoint. (5,?)
Adding Y1 and Y2 equals 11. Then the y variables have to be divided by 2 which is 11 divided by 2 equals 5.5, the 5.5 represents the y value of the midpoint. (?,5.5)
The final answer is Midpoint = (5,5.5)
The graph shows the relationship between the United States dollar and the euro, the currency of the European Union, in December 2011. Part B: Justify why the relationship shown in the graph is a proportional relationship.
Answer:
Step-by-step explanation:
Let the equation of the line representing relation between the euros and dollars is,
E = mD + b
Where 'E' = Number of euros
D = Number of dollars
m = slope of the line
b = y-intercept
Slope of a line which passes through two points (120, 90) and (400, 300) will be,
m = [tex]\frac{y_2-y_1}{x_2-x_1}[/tex] = [tex]\frac{300-90}{400-120}[/tex]
m = 0.75
Equation of the line passing through (120, 90),
90 = 0.75(120) + b
b = 90 - 90 = 0
Therefore, equation of the line will be,
E = mD
E ∝ D
Here m = Proportionality constant
And the relation between the numbers of Euros and US dollars is a proportional relationship.

Answer:
-161.57°, or 198.43°
Step-by-step explanation:
The third-quadrant angle can be found using the usual rectangular-to-polar conversion. The angle is given by ...
θ = ATAN2(x, y) = ATAN2(-12, -4) ≈ -161.57°
__
More conventionally, the reference angle is ...
tan(θ) = y/x = -4/-12 = 1/3
θ = arctan(1/3) ≈ 18.43° . . . . angle from -x axis (CCW)
Since this is a 3rd-quadrant angle, the positive angle value will be 180° plus the reference angle:
180° +18.43° = 198.43°
The angle most directly measured from the +x axis is ...
360° -198.43° = -161.57°
You recently borrowed $500 from a friend. You signed a contract that requires you to pay back one third of the loan every month for three months. How much will you have to pay back each of the first two months? How much will you have to pay back the third month?
The amount of money I would repay in the first month is $166.67.
The amount of money I would repay in the second month is $166.67.
The amount of money I would repay in the third month is $166.66.
How much would I repay each month?In order to determine the money that would be repaid each of the first two months, multiply 1/3 by the amount of the loan.
1/3 x $500 = $166.67
Amount to be repaid in the third month = $500 - (166.67 x 2) = $166.66

Answer:
h = 3.6
Step-by-step explanation:
This is just substituting in for variables and solving for x. The hard part is knowing the formula.
R = h((a+b)/2) where a and b are the 2 different bases, h is the height or latitude, and R is the area of a trapezoid, is the formula.
Given that R = 8.1, a = 1 and b = 3.5, we can substitute these equations in the formula.
(8.1) = h(((1) + (3.5)) / 2)
= h((4.5) / 2)
= h(2.25)
8.1/2.25 = h
3.6 = h
