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

              \bold{8.\quad y=sin\bigg(8x + \dfrac{8}{\pi}\bigg)}

<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) = \dfrac{2\pi}{B}
  • Phase Shift = \dfrac{C}{B}
  • Vertical Shift = D (positive is up, negative is down)

7. Given:

  • A = 2
  • P = π = \dfrac{2\pi}{B}  → B = 2
  • C = 0 (none)
  • D = -3

--> y = 2 sin (2x) - 3

8. Given:

  • A = 1
  • P = \dfrac{\pi}{4} = \dfrac{2\pi}{B}  → B = 8
  • \text{Phase Shift = }-\pi = \dfrac{C}{8}\implies C = -8\pi
  • D = 0 (none)

\implies y=sin\bigg(8x + \dfrac{8}{\pi}\bigg)

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:

\text{To find : Two closest square roots of }\sqrt{\frac{1}{5}}=\sqrt{0.2}\\\\ \sqrt{0}

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

For checking :

\sqrt{\frac{1}{5}}=\sqrt{0.2}=0.45

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.
