Cos(2theta)=11 sin(theta)-5

lubasha [3.4K]

$\cos2\theta=11\sin\theta-5$
$1-2\sin^2\theta=11\sin\theta-5$
$2\sin^2\theta+11\sin\theta-6=0$
$(2\sin\theta-1)(\sin\theta+6)=0$
$\implies\begin{cases}2\sin\theta-1=0\\\sin\theta+6=0\end{cases}$

The second equation gives $\sin\theta=-6$ , but $-1\le\sin\varphi\le1$ for any real $\varphi$ , so we can ignore this equation.

This leaves us with

$2\sin\theta-1=0\implies \sin\theta=\dfrac12\implies\theta=\dfrac\pi6+2\pi k,\theta=\dfrac{5\pi}6+2\pi k$

where $k$ is any integer.

Thereare 30 students in mr.holland's music class.if 30% of the students play in the school band,how many students in the class p

stiv31 [10]

9 students in the class play in the school band.

30% of 30
Well, when doing a percentage you first turn the percentage into a decimal (move the % two units to the left). So 30% = 0.3

In math, the word of means multiplication, so: 0.3 x 30
Which equal 9.

You can also turn the percentage into a fraction, it's really up to preference.

30/100 of 30 = 3/10 of 30 = 3/10 x 30 = 3/10 x 30/1 = 9/1 or 9
