give the exact form and decimal form of the equation

8=9sin(6x)

simplify the equation into the form sin(ax)=b and use the inverse sin to solve for x

Respuesta :

Answer:

Exact form: [tex]\sin{(6x)} = \frac{8}{9}[/tex]

Decimal form: [tex]\sin{(6x)} = 0.8889[/tex]

The solution for x is: The solution for x is of 10.455º

Step-by-step explanation:

We are given the following equation:

[tex]8 = 9\sin{(6x)}[/tex]

Placing into the desired format, the exact format is:

[tex]\sin{(6x)} = \frac{8}{9}[/tex]

In the decimal part, we divide 8 by 9. So

[tex]\sin{(6x)} = 0.8889[/tex]

Solving for x:

We apply the inverse sine. So

[tex]\sin^{-1}{\sin{(6x)}} = \sin^{-1}{0.8889}[/tex]

[tex]6x = 62.73[/tex]

[tex]x = \frac{62.73}{6}[/tex]

[tex]x = 10.455[/tex]

The solution for x is of 10.455º
