Solve the equation in the interval 0 to 2pi.
galben [10]

Answer:

You don't need to single out \cos \theta to solve this question.  

To solve:

\begin{aligned}3 \cos 4 \theta & = -2\\\\\cos 4 \theta & = -\dfrac{2}{3}\\\\4 \theta & = \cos^{-1}\left( -\dfrac{2}{3\right)}\\\\\implies 4 \theta & =2.30053... \pm 2 \pi n, -2.30053...\pm 2 \pi n\\\\\theta & =\dfrac{2.30053...}{4} \pm \dfrac{\pi n}{2}, -\dfrac{2.30053...}{4}\pm \dfrac{\pi n}{2}\end{aligned}

So for the given interval 0\leq \theta \leq 2 \pi

\implies \theta =0.575, 2.146, 3.717, 5.288, 0.996, 2.566, 4.137, 5.708\:\:(\sf 3 \: d.p.)

(As confirmed by the attached graph)

There are 12 more girls than boys in a drama club. The ratio of girls to boys is 9:5. How many girls and how many boys are in th
lana [24]

Answer:

27 girls and 15 boys

Step-by-step explanation:

To solve this, I just used guess and check.

9:5 is a ratio, which means we can multiply each side by any number as long as we do it to both sides.

If we multiply the ratio by 3, we get (9 x 3) : (5 x 3) which is 27:15

And as it turns out, 27-15 is 12, which in this context means there are 12 more girls in drama club, so it works out.
