Find the product of 4cis (pi/4) times 5cis (pi/6) in polar form.
KengaRu [80]

We have the following expression

4\cdot\text{cis(}\frac{\pi}{4})\cdot5\text{cis(}\frac{\pi}{6})

This is equivalent to

4\cdot\text{cis(}\frac{\pi}{4})\cdot5\text{cis(}\frac{\pi}{6})=(4\times5)cis(\frac{\pi}{4}+\frac{\pi}{6})

Since

\frac{\pi}{4}+\frac{\pi}{6}=\frac{6\pi+4\pi}{24}=\frac{10}{24}\pi=\frac{5}{12}\pi

we have that

4\cdot\text{cis(}\frac{\pi}{4})\cdot5\text{cis(}\frac{\pi}{6})=20cis(\frac{5\pi}{12})

Therefore, the answer is the second option from top to bottom.

The volume of a right cone is 3525\piπ units^3
Greeley [361]

The height of the right cone given its volume and its diameter is  47 units.

<h3>What is the height?</h3>

A cone is a three-dimensional object that has a circular base and a vertex.

Height of the cone = Volume of a cone ÷ 1/3(πr²)

Where:

  • π = 22/7
  • r = radius = diameter / 2 = 30 / 2 = 15 units
  • h = height

3525π÷ (1/3 x π x 15²) = 47 units

  • Left to Right  

Equality Properties

  • Multiplication Property of Equality
  • Division Property of Equality
  • Addition Property of Equality
  • Subtraction Property of Equality<u> </u>

Step-by-step explanation:

<u>Step 1: Set Up</u>

Let's let our number be set by variable <em>n</em>.

We add 7 to it: n + 7

We then double that entire expression: 2(n + 7)

That expression is equal to 82.8: 2(n + 7) = 82.8

<u>Step 2: Solve for </u><em><u>n</u></em>

  1. [Division Property of Equality] Divide 2 on both sides:                               n + 7 = 41.4
  2. [Subtraction Property of Equality] Subtract 7 on both sides:                      n = 34.4

∴ Caroline's original number is 34.4.
