Answer: 7. y = 2 sin (2x) - 3

<u>Step-by-step explanation:</u>
The general form of a sine equation is: y = A sin (Bx - C) + D where
- Amplitude = |A|
- Period (P) =

- Phase Shift =

- Vertical Shift = D (positive is up, negative is down)
7. Given:
- A = 2
- P = π =
→ B = 2 - C = 0 (none)
- D = -3
--> y = 2 sin (2x) - 3
8. Given:
- A = 1
- P =
=
→ B = 8

- D = 0 (none)

2 5/8 divided by 3
(2*8)+5/8 divided by 3
16+5/8 divided by 3
(3*7/2^3)(1/3)
3*7/2^3*3
7/2^3
7/8
each friend would get 7/8

Answer:
For the given square root, two closest perfect square are are 0 and 1 and their square roots are 0 and 1 respectively.
Step-by-step explanation:

Hence, the two nearest square roots of the given square root are 0 and 1
For checking :

And, clearly 0.45 lies between 0 and 1
⇒ √0 < √0.2 < √1
⇒ 0 < 0.45 < 1
Hence, For the given square root, two closest perfect square are are 0 and 1 and their square roots are 0 and 1 respectively.
