By Quadratic Formula factors of [tex]a^2+4b^2[/tex] are [tex](a+2bi),(a-2bi)[/tex].

What is Quadratic Formula?

The quadratic formula in elementary algebra is a formula that gives the solution(s) to a quadratic equation. In addition to the quadratic formula, there are various methods for solving quadratic equations, including factoring (direct factoring, grouping, and the AC technique), completing the square, graphing, and others.

The following general quadratic equation is given:

[tex]ax^2+bx+c=0[/tex]

The quadratic formula is:

[tex]x=\frac{-b+\sqrt{b^2-4ac} }{2a}, \frac{-b-\sqrt{b^2-4ac} }{2a}[/tex];

where x stands for an unknown, a, b, and c are constants, and a≠0.

Each of these two answers is also referred to as a quadratic equation root (or zero). These roots, which are clearly stated as [tex]y = ax^2 + bx + c[/tex], are the x-values at which any parabola crosses the x-axis geometrically.

Calculation:

Given;

[tex]y=a^2+4b^2;\\[/tex]

By comparing this with general equation [tex]x=a,a=1,b=0,[/tex][tex]c=4b^2[/tex]

By substituting in the formula;

[tex]x=\frac{-0+\sqrt{(0)^2-4(1)(4b^2)} }{2(1)} =2bi\\(or) x=\frac{-0-\sqrt{(0)^2-4(1)(4b^2)} }{2(1)} =-2bi[/tex]

That gives us;

[tex]y=(a+2bi)(a-2bi)[/tex]

By Quadratic Formula factors of [tex]a^2+4b^2[/tex] are [tex](a+2bi),(a-2bi)[/tex].

Answers

Answer:

The distance is 4

Step-by-step explanation:

Given:

x1 = 7

x2 = 7

y1 = -1

y2 = -5

[tex]d=\sqrt{(x2-x1)^2+(y2-y1)^2} \\\\d=\sqrt{(7-7)^2+(-5+1)^2}\\\\d=\sqrt{(0)^2+(-4)^2} \\\\d=\sqrt{0+16} \\\\d=\sqrt{16} \\d=4[/tex]

Answer:

brian, tim and kenny got paid a total of $240 for mowing neighborhood lawns . They split the money in the ratio of 5:9:10 . how much money did each boy make . PLEAEEEE SHOW THE work i’m really struggling rn

Answers

Answer:

$50 for Brian

$90 for Tim

$100 for Kenny

Step-by-step explanation:

Let 5x = amt for Brian

     9x = amt for tim

     10x = amt for ken

5x + 9x + 10x = 240

24x = 240

x = 10

5x = 5(10) = $50 for Brian

9x = 9(10) = $90 for Tim

10x = 10(10) = $100 for Kenny

Answer:

Step-by-step explanation:

5x + 9x + 10x = $240

x = $10

What is the domain of the relation? On a coordinate plane, a graph of an image has 3 connected lines. The first line goes from (negative 4, negative 4) to (negative 2, 1). The second line goes from (negative 2, 1) to (1, 1). The third line goes from (1, 1) to (6, 4). There are closed circles at (negative 4, negative 4) and (6, 4).

Answers

Given:

The graph of a relation contains three lines.

The first line goes from (-4,-4) to (-2, 1).

The second line goes from (-2, 1) to (1, 1).

The third line goes from (1, 1) to (6, 4).

There are closed circles at (-4,-4) and (6, 4).

To find:

The domain of the relation.

Solution:

Domain of relation is the set of x-values or the set of input values.

First line is defined from -4 to -2, second line is defined from -2 to 1 and third line is defined from 1 to 6.

There are closed circles at (-4, -4) and (6, 4). It means -4 and -6 are included in the domain.

Since the input values for the given relation is from -4 to 6, where -4 and 6 are included, therefore the domain of the relation is [-4,6].

Answer:

-4

Answers

Answer:

actual area = 900 square feet

ratio = 1cm2 : 36ft2

Step-by-step explanation:

square room

area = 25cm2

1 side =  √ 25

         =  5cm

1cm = 6ft

5cm = 5 x 6

      = 30ft = 1 side

actual area = 30 x 30 = 900ft

ratio = square cm : square feet

       = 25     :     900  ( simplify both ratio )

      = 1cm2  :  36ft2

Mr. And Mrs. Griffin hope to send their daughter to college in fourteen years. How much money should they invest now at an interest rate of 9.5% per year, compounded continuously, in order to be able to contribute $8,500 to her education?

Answers

Answer:

$2,385.75 = P

Step-by-step explanation:

In order to calculate this we need to use the following compound interest formula and solve for the initial investment amount which is P.

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

A = the future value of the investment/loan, including interest

P = the principal investment amount (the initial deposit or loan amount)

r = the annual interest rate (decimal)

n = the number of times that interest is compounded per unit t

t = the time the money is invested or borrowed for

If we plug in the values provided in the question which is compounded once per year we would get the following equation which we can solve for P.

8500 = P (1 + (0.095/1))^(1*14)

8500 = P (1.095)^(14)

8500 = P (3.56285)

2,385.75 = P

Step-by-step explanation:

Answer: okay so this is a long process

Step-by-step explanation:

the measure of angle N is 65 degrees because when calculating the angle, it is always half of the arc it makes. K is 30 because the arc it makes is 60 degrees and half of 60 is 30. Y is 45 because half of 90 is 45. All of the inside angles of a triangle add up too 180 degrees. So add 30 to 45 and you would get 75, then subtract 75 from 180 to get 105. So the measure of KNY is 105 degrees.

0 = - 108 + 12x

12x = 108

x = 108 / 12
