<u>Geometry</u>

Volume of a Cylinder Formula: V = πr²h

  • V is volume
  • r is radius
  • h is height

Step-by-step explanation:

<u>Step 1: Define</u>

Radius <em>r</em> = 2 units

Height <em>h</em> = 16 units

<u>Step 2: Find Volume</u>

  1. Substitute in variables [Volume of a Cylinder Formula]:                                V = π(2 units)²(16 units)
  2. [Volume] Evaluate exponents:                                                                         V = π(4 units²)(16 units)
  3. [Volume] Multiply:                                                                                             V = π(64 units³)
  4. [Volume] Multiply:                                                                                             V = 201.062 units³
  5. [Volume] Round:                                                                                               V ≈ 201.06 units³

For sin2x+cosx=0, use a double-angle or half-angle formula to simplify the equation and then find all solutions of the equation
Archy [21]

Answer:

Step-by-step explanation:

Given is a trignometric equation in x, as

sin2x+cosx=0

TO make it in one trig ratio, we can replace sin2x as 2sinx cosx

WE get now

2sinxcosx+cosx=0\\

cosx(2sinx+1)=0\\cosx=0, sinx =-0.5\\

Principal solution is x=\frac{\pi}{2} , \frac{-\pi}{6}

x = ±π/2 + 2kπ, where k is any integer or

x=±pi/6 +k pi, where k is any integer.

General solution is

Answer:

Lead-the-market pay strategies. An employer may choose to establish an internal compensation strategy that is in excess of the pay rates in the prevailing marketplace. This compensation strategy may increase the supply of candidates, increase selection rates of qualified applicants, decrease employee turnover, increase morale and productivity, or prevent unionization efforts. However, prior to implementing a lead compensation strategy, an organization should carefully consider what benefits it expects to realize from such a strategy, keeping in mind that this type of structure has the greatest propensity of increasing overall labor costs.
