ANSWER

Phase shift: 1 unit to the right.

EXPLANATION

The given sine function is

$y = 1 + \sin2(x - 1)$

In mathematics, the phase shift of a trigonometric function is also called the horizontal shift.

This function is shifted 1 unit to the right.

The phase shift is one unit to the right.

Answer:

The phase shift:

1 unit to the right and 1 unit up

Step-by-step explanation:

∵ y = 1 + sin2(x - 1)

∴ y = 1 + sin(2x - 2)

∵ y = Sin(Bx - C) + D

∵ The vertical shift is D

∴ The horizontal shift is -C/B

∴ The vertical shift is 1 unit up

∴ The horizontal shift is --2/2 = 1 ⇒ 1 unite to the right

The combined area of two squares is 80 square centimeters. Each side of one square is twice as long as a side of the other squar

Answer:

The length of each side of the larger square is<u> 8 </u>centimeter.

Step-by-step explanation:

Given:

The combined area of two squares is 80 square centimeters. Each side of one square is twice as long as a side of the other square.

Now, to find the length of each side of the larger square.

Let $s$ be the length of the smaller square.

So, the length of the larger square = $2s.$

Now, we find the areas of the square by putting formula:

The area of smaller square = length² $=s^2.$

The area of larger square = (length)² $=(2s)^2=4s^2.$

As, given:

The combined area of two squares is 80 square centimeters.

According to question:

$s^2+4s^2=80\\5s^2=80$

<em>So, dividing both sides by 5 we get:</em>

$s^2=16$

<em>Using square root on both sides we get:</em>

$s=4\ centimeter.$

And, to get the length of each side of the larger square we substitute the value of $s$ :

$2s=2\times 4=8\ centimeter.$

<u>The length of larger square = 8 centimeter</u>

Therefore, the length of each side of the larger square is 8 centimeter.
