Q7 Q26.) Find the quotient of the complex numbers and leave your answer in polar form.

ANTONII [103]

For any complex numbers in polar form $c_1 = r_1\text{cis}(\theta_1),\ c_2 = r_2\text{cis}(\theta_2)$

(Where $\text{cis}(\theta) = \cos(\theta) + i\sin(\theta)$ )

Then $\dfrac{c_1}{c_2} = \dfrac{r_1}{r_2}\text{cis}(\theta_1-\theta_2)$

So then for your problem, that would be

$\dfrac{z_1}{z_2} = \dfrac37\text{cis}\left(\dfrac\pi8-\dfrac\pi9\right)=\boxed{\dfrac37\text{cis}\left(\dfrac\pi{72}\right)}$

So that would be $\boxed{\dfrac37\left(\cos\left(\dfrac\pi{72}\right)+i\sin\left(\dfrac\pi{72}\right)\right)}$

Hope this helps.

A cylindrical container has a base area of 100 m2 and is 12m high. If the container is one-third filled with water, what's the v

yuradex [85]

The volume of a cylinder is given by the base area times height. (i.e. V = base area x height). Given that the given cylinder is one-third filled with water, the height of the water in the cylinder = 1/2 x height of the cylinder = 1/3 x 12 = 4 m. Therefore, the volume of water in the cylinder = base area of the cylinder x height of water in the cylinder = 100 x 4 = 400 cubic meter.
