Answer:

Graph 1.

Step-by-step explanation:

Th graph of $y=\cos{(x-\pi)}$ looks exactly like the graph of $y=\cos{x}$ if we shifted the axes $\pi$ units to the left. This has the visual effect of shifting the graph forward $\pit$ $\pi$ units (imagine filming someone and panning the camera to the left; the person moves right in the camera frame).

So the point at $x=0$ , which used to be $(0, \cos{0})=(0,1)$ is now $(0,\cos{(0-\pi)})=(0,\cos{(-\pi)})=(0,-1)$ , which we can find on the first graph.

The formula for a sequence or series used to find any term in that sequence or series

ANTONII [103]

Step-by-step explanation:

Tn = a + (n - 1) d

Where

Tn is the nth term of the sequence

a is the first term of the sequence

n is the number/term of the sequence to be solved

d is the common difference

The length of one leg of a right triangle is 24 feet and the length of the hypotenuse is 40 ft what is the length of the other l

Rama09 [41]

To solve for the other leg, you need to use Pythagorean theory.

The theory states that C^2 = A^2 + B^2

In your case, you have to solve for B.
C = 40 (hypotenuse) A = 24 (leg 1)

The formula rewritten for B is $b= \sqrt{c^{2}-a^{2} }$

Now, you can solve.

$b= \sqrt{c^{2}-a^{2} }

b= \sqrt{40^{2}-24^2 }

b = \sqrt{1600 - 576}

b = \sqrt{1024}

b = 32$

Therefore, B = 32.

So the second leg is 32 feet.

There are white, blue, and red boats in a marina. Three-fourths of the boats in the marina are white, 4/7 of the remaining boats

insens350 [35]

Answer:

There are 84 total boats.

Step-by-step explanation:

In order to find this, we first need to find the fraction which are red. We can do this by multiplying the whole by how many are not white.

1 * 1/4 = 1/4

Now we take that amount and multiply it by the amount that are not blue of the remaining.

1/4 * 3/7 = 3/28

Now that we have this, and we know this is 9 boats, we can divide 9 by this fraction and it will give us the total number of boats.

9 ÷ 3/28 = 84
