               KL + LM = KM
  (8x - 5) + (6x + 3) = KM
(8x + 6x) + (-5 + 3) = KM
                   14x - 2 = KM

Using the 3 functions below, make the desired transformation(s) to the correct function and describe the transformation(s). Writ
Eduardwww [97]

Answer:

The transformation of g(x) to k(x) consists in a vertical translation. The new equation is k(x) = -12\cdot x-6.

Step-by-step explanation:

Let g(x) = -12\cdot x - 3. We proceed to make the required transformations on g(x), which consists in one vertical translation, 3 units in the -y direction. That is to say:

k(x) = g(x) - 3 (1)

k(x) = (-12\cdot x - 3) - 3

k(x) = -12\cdot x-6

Then, the transformation of g(x) to k(x) consists in a vertical translation. The new equation is k(x) = -12\cdot x-6.

Rebecca has 12 photos she wants to hang side by side on her wall.A. If she only wants to display 8 of the photos, in how many wa
Mariana [72]

A.

If she will choose 8 from 12 photos, the total number of ways she can choose is given by a combination of 12 choose 8, since the order of the photos doesn't matter.

The formula for a combination of n choose p is:

C(n,p)=\frac{n!}{p!(n-p)!}

For n = 12 and p = 8, we have:

C(12,8)=\frac{12!}{8!(12-8)!_{}}=\frac{12\cdot11\cdot10\cdot9\cdot8!}{8!\cdot4!}=\frac{12\cdot11\cdot10\cdot9}{4\cdot3\cdot2}=495

So there are 495 ways.

B.

If she wants to arrange the 12 photos, the total number of ways is given by the factorial of 12:

12!=12\cdot11\cdot10\cdot9\cdot8\cdot7\cdot6\cdot5\cdot4\cdot3\cdot2=479001600

There are 479,001,600 ways.

C.

Since 10 photos already have specific places, we need to calculate the number of ways to arrange the other two photos in the two remaining places.

In this case, there are only 2 ways of organizing the remaining two photos:

Photo 1 first, photo 2 last, or photo 1 last and photo 2 first.

Find the length of the hypotenuse.​
IRISSAK [1]

Answer:

6

Step-by-step explanation:

Using the sine ratio in the right triangle

let x = hypotenuse and sin45° = \frac{\sqrt{2} }{2}, then

sin45° = \frac{opposite}{hypotenuse} = \frac{3\sqrt{2} }{x}

and

\frac{3\sqrt{2} }{x} = \frac{\sqrt{2} }{2} ( cross- multiply )

\sqrt{2} × x = 6\sqrt{2}

Divide both sides by \sqrt{2}

x = 6
