Answer:

6/5

Step-by-step explanation:

When two lines are perpendicular to each other, their slope are the negative reciprocal to each other. (so you flip them and change the sign)

Please find the square roots of the following complex number.

Hey there,

First, find the square root of the given equation.

$\sqrt{z}=\sqrt{81(\text{cos}(\frac{4\pi}{9})+i\text{sin}(\frac{4\pi}{9})}\\=9\text{cos}\frac{1}{2}(2k\pi+(\frac{4\pi}{9}))+i\text{sin}\frac{1}{2} (2k\pi+(\frac{4\pi}{9}))$

Keep in mind that this is solved for k = 0 and 1.

Second, simplify.

$=9\text{cos}(\frac{2\pi}{9})+i\text{sin}(\frac{2\pi}{9})~\text{or}~9\text{cos}(\frac{11\pi}{9})+i\text{sin}(\frac{11\pi}{9})$

Best of Luck!

Regular pyramid B= P= H= l= LA= SA= V=

devlian [24]

Answer:

B (Base surface area) = 16 $m^{2}$

P (Perimeter of the base) = 16 m

H (Height) = 6 m

L (Not sure what L means. I assume it's the slant height??) = 6.32 m

LA (I assume lateral surface area) = $50.59 m^{2}$

SA (I assume total surface area) = $66.59 m^{2}$

V (volume) = $32 m^{3}$

Step-by-step explanation:

Sorry if anything is wrong. It would be more helpful to put the names, instead of acronyms.
