\huge \boxed{\mathbb{QUESTION} \downarrow}

  • What is the solution to the inequality -3x-42>3 ?

\large \boxed{\mathfrak{Answer \: with \: Explanation} \downarrow}

- 3 x - 42 \gt 3

Add 42 to both sides.

-3x>3+42

Add 3 and 42 to get 45.

-3x>45

Divide both sides by -3. As -3 is <0, the inequality direction has changed.

x

Divide 45 by -3 to get -15.

for a short time after a wave is created by wind the height of the wave can be modeled using y= a sin 2pit/T where a is the ampl
dangina [55]

Answer:

y = 4 sin(t/2 + 4π/3) − 2

Step-by-step explanation:

General form:

y = a sin(2π/T t)

Given a = 4 and T = 4π:

y = 4 sin(2π/(4π) t)

y = 4 sin(t/2)

Add horizontal shift of -4π/3 and vertical shift of -2:

y = 4 sin(t/2 − (-4π/3)) − 2

y = 4 sin(t/2 + 4π/3) − 2
