Answer:

6) ≈ 904.74                            7) 88

Step-by-step explanation:

use a caulater and the proper equations

to find the volume of a sphere you must use V=4\3•π•r^3 (four thirds times pi time the radius cubed), plug in 6 into "r" in the equation and that should give you roughly 904.74

To find the volume of a pyramid you must use the equation Lwh\3 (length times width times hight product of which is divided by 3) giving you 88

What is the rectangular form of z= 40(cos(7pi/6)+ i sin(7pi/6))
Anastaziya [24]

Answer:

C. z = -20\sqrt{3}-i\,20

Step-by-step explanation:

The rectangular form of a complex number is represented by the following formula:

z = a+i\,b (1)

Where each coefficient can be determined as function of the polar components:

a = r\cdot \cos \theta (2)

b = r\cdot \sin \theta (3)

Where:

r - Magnitude of the complex number, dimensionless.

\theta - Direction of the complex number, measured in radians.

If we know that r = 40 and \theta = \frac{7\pi}{6}, then the rectangular form of the number is:

a = 40\cdot \cos \frac{7\pi}{6}

a = -20\sqrt{3}

b = 40\cdot \sin \frac{7\pi}{6}

b = -20

The rectangular form of z=40\cdot\left(\cos \frac{7\pi}{6}+i\,\sin \frac{7\pi}{6}\right) is z = -20\sqrt{3}-i\,20. The correct answer is C.
