Hey there :)

Answer:

y = 4/5x - 2

Step-by-step explanation:

Begin by using the slope formula to calculate the slope:

$m = \frac{\text{rise}}{\text{run}} = \frac{y_2 - y_1}{x_2 - x_1}$

Plug in the coordinates into the equation:

$m = \frac{6 - 2}{10 - 5}$

Simplify:

$m= \frac{4}{5}$

Plug in the slope, as well as the x and y values of a point into the equation

y = mx + b to solve for the b value:

2 = 4/5(5) + b

2 = 4 + b

2 - 4 = b

b = -2.

Therefore, the equation of this line is:

y = 4/5x - 2

The lowest is the square root of 9 which is 3. After that is 3.15, 13/4 (3.25), 3 1/2 (3.50). My explanation would be: first I found out the square root of 9. Then divided 13 by 4.

1. What pattern does the power of i follow?

Darina [25.2K]

Answer:

Step-by-step explanation:

Start by doing a much simpler problem

One

i^0 = 1

i^1 = i

i^2 = i^2 = - 1

i^3 = i^3 = (-1) * i = -i

i^4 = i^4 = (i)^2 * i^2 = -1 * -1 = 1

So now you are ready to tackle the question you were given.

Two

Every 4th power of i repeats itself. You must get one of the four answers above.

So divide 5689 by 4. What do you get?

1422.25

What does that mean?

It means that you run through the cycle of four 1422 times. What does that mean?

1 * 1 * 1 * 1 * 1 * 1 * 1 * 1 ....................................*1

There are 1422 ones in that expression.

What about the 0.25? What about that?

That means that you have one i left over.

So the answer is i

Three

The simple question defines the pattern which will repeat itself over and over again. By knowing how the simple pattern works you can develop any power of i. For example

i^15622 =

3905.5

0.5 is the same as 2/4

i^2 = -1

i^15622 = - 1

In paralelleogram ABCD, diagnosis AC and BD intersect at point E, BE=X2-40 and DE= 6x. What is BD?

Alchen [17]

Answer:

Length of BD = $x^2$ +6x - 40

Step-by-step explanation:

In parallelogram ABCD , diagonals AC and BD intersect at E .

In a parallelogram , the two opposite sides are parallel and equal in length.

Also opposite angles of a paralleogram are equal .

Here the length of the parts of a diagonal is given.

BE = $x^{2}$ - 40

DE = 6x

Since the length of whole diagonal is the sum of the lengths of the parts of the diagonal ,

Length of BD = BE + DE

= $x^{2}$ -40 + 6x

Length of BD = $x^2$ +6x - 40
