Answer:

9 cm

Step-by-step explanation:

Volume of the prism:

V = lwh = 3*9*27 = 729 cm³

Volume of the cube:

V = a³ = 729 cm³

Side of the cube:

a = ∛729 = ∛9³ = 9 cm

Step-by-step explanation:

V = l•w•h = 3•9•27 = 729cm³
V = a³ <=> a³ = 729
a = 9cm

Whay is infinity raise to any number equals?

tia_tia [17]

Infinity raised to any number greater than 1 is always equal to infinity. But if infinity is raised to 0, then the result is indeterminate. Normally, if any number is raised to 0 is 1 but it is different for infinity.

Trig: Which complex number's graph is shown?

Andrei [34K]

ANSWER

$2 \sqrt{2} ( \cos( \frac{7\pi}{4} + i \sin( \frac{7\pi}{4} ) )$

EXPLANATION

The complex number shown has coordinates (2,-2)

$z = 2 - 2i$

The modulus is

$|z| = \sqrt{ {2}^{2} + {( - 2)}^{2} }$

$|z| = \sqrt{ 8} = 2 \sqrt{2}$

The argument is

$\theta= \tan^{ - 1} ( \frac{ - 2}{2} )$

$\theta= \tan^{ - 1} ( -1) = \frac{7\pi}{4}$

The polar form is

$2 \sqrt{2} ( \cos( \frac{7\pi}{4} + i \sin( \frac{7\pi}{4} ) )$

The first option is correct.
