Integral of sin^4 (6x) dx

DENIUS [597]

Hello,

$\boxed{sin^4\ x= \frac{3}{8}- \frac{cos\ 2x}{2}+\frac{sin\ 4x}{8} }\\

Let's assume t=6x \ dt=6\ dx\\

 \int\limits {sin^4\ 6x} \, dx = \frac{1}{6} *\int\limits {sin^4\ t} \, dt \\

= \dfrac{1}{6} *( \frac{3t}{8} - \frac{sin\ 2t}{4} +\frac{sin\ 4t}{32})+C\\

= \dfrac{3x}{8} - \frac{sin\ 12x}{24} +\frac{sin\ 24x}{192} +C

Atlantic auditorium has 850 seats. Tickets were sold for 816 of the seats. For what percent of the seats were the tickets sold?

Mariana [72]

Answer:

<u>96 percent</u> of the seats were the tickets sold.

Step-by-step explanation:

Given:

Atlantic auditorium has 850 seats. Tickets were sold for 816 of the seats.

Now, to find percent of the seats of the tickets sold.

Total number of seats = 850.

Tickets sold for the total seats = 816.

So, to find the percent of the seats of the tickets sold:

$\frac{816}{850}\times 100$

$=0.96\times 100$

$=96\%.$

Therefore, 96 percent of the seats were the tickets sold.
