Answer:  \bold{D)\quad y = 2sin(3x)}

<u>Step-by-step explanation:</u>

\text{The standard form of a sine equation is: y=A sin(Bx - C) + D}\\\\\bullet\text{A = amplitude}\\\\\bullet\text{Period = }\dfrac{2\pi}{B}\\\\\bullet\text{Phase Shift = }\dfrac{C}{B}\\\\\bullet\text{D = vertical shift (up if positive, down if negative)}

In the given graph,

  • A (amplitude) = 2
  • P (period) = \dfrac{2\pi}{3} --> B = 3
  • Phase Shift \bigg(\dfrac{C}{B}\bigg) = 0  --> C = 0
  • D (vertical shift) = 0

\implies \large\boxed{y = 2sin(3x)}

<em>see graph below for verification</em>

Which is the longer length 29ft or 9 yards
andreev551 [17]
Convert 9 yards into feet:  9 yards * (3 feet) / (1 yard) simplifies to 27 feet.

9 yards, or 27 feet, is shorter than 29 feet.

29 feet is longer than 27 feet.

A certain plant grows 134 inches every week. How long will it take the plant to grow 714 inches?
Bond [772]

The information we know:

1 week = 134 inches

x = 714

What I did was, I divided 714 by 134 to find the amount of weeks:

714/134 = 5.3

So, from the equation, basically, in 6 weeks (actually 5.3 weeks) the plant will grow 714 inches long
