Using proportions, it is found that 400 light years have $3.6 \times 10^{18}$ meters.

To find how many meters are 400 light years, we use proportions, with a rule of three.

One light year has $9 \times 10^{15}$ meters.
How many meters are there in 400 light years, which in scientific notation, is $4 \times 10^2$ light years?

The<u> rule of three</u> is:

1 light year - $9 \times 10^{15}$ meters.

$4 \times 10^2$ light years - x meters

Applying cross multiplication:

$x = 9 \times 10^{15} \times 4 \times 10^2 = 36 \times 10^{17} = 3.6 \times 10^{18}$

Thus, 400 light years have $3.6 \times 10^{18}$ meters.

The first three steps of completing the square to solve the quadratic equation x² + 4x - 6 = 0, are

slavikrds [6]

Answer:

The next 3 steps are

Step 4: $(x+2)=\pm \sqrt{10}$

Step 5: $x=-2\pm \sqrt{10}$

Step 6: $x=-2+\sqrt{10}\ or\x=-2-\sqrt{10}$

Step-by-step explanation:

Given:

Quadratic Equation is

x² + 4x - 6 = 0

To Find:

x = ?

Solution:

Step 1: x2 + 4x = 6

Step 2: x2 + 4x + 4 = 6 + 4

Step 3: (x + 2)2 = 10

Step 4: $(x+2)=\pm \sqrt{10}$

Step 5: $x=-2\pm \sqrt{10}$

Step 6: $x=-2+\sqrt{10}\ or\x=-2-\sqrt{10}$

Pls, help with this math question

Aleks04 [339]

Step-by-step explanation:

OCB=CBO(base angle of isosceles triangle are equal)

now,

OCB+CBO+BOC=180°(sum of angles of triangles)

BOC=180-62

BOC=118°

again,

x=BOC/2{inscribed angle is half of central angle standing on Same base}

x=118/2

x=59°

How to write standard form for: (please answer this question soon )

professor190 [17]

Put the terms in order of decreasing degree, all on the left. When convenient, it is nice to have mutually prime integer coefficients with the leading one positive.

a) x² -2x +1 = 0

b) x² +15 = 0

c) 4x² -12 = 0
or, better, divide out the common factor of 4.
x² -3 = 0

d) 3x² -x -5 = 0

_____
Shown is the standard form for a single-variable second-degree equation. Form varies depending on the nature of the equation. Equations of conic sections have different standard forms, depending on the curve.
