Linear Velocity = angular velocity x radius
V = 2.65 x 1.4 = 3.71 feets per second.
Distance = velocity x time = 3.71 x 3 x 60 = 667.8 feet.

kofi and kojo were given 380 to share .kojo had 75 more than kofi. If kofi share is x find an expression for kojo share​
AleksAgata [21]

Answer:

227.5

Step-by-step explanation:

x=Kofi

x+75=Kojo

   x+x+75=380

    2x+75=380

          2x=305

             x=152.5

       Kojo=152.5 plus 75

               227.5

<u>Algebra I</u>

Simple Interest Rate Formula: A = P(1 + rt)

  • <em>P</em> is principle amount
  • <em>r</em> is rate
  • <em>t</em> is time

Step-by-step explanation:

<u>Step 1: Define</u>

<em>Identify variables.</em>

<em>P</em> = $52,400

<em>r</em> = 6%

<em>t</em> = 5

<u>Step 2: Find Current Investment Value</u>

  1. Substitute in variables [Simple Interest Rate Formula]:                                 A = 52,400(1 + 0.06 · 5)
  2. [Order of Operations] Evaluate:                                                                      A = $68,120

<u>Step 3: Find Total Return</u>

  1. Set up:                                                                                                               R = A - P
  2. Substitute in variables:                                                                                     R = 68,120 - 52,400
  3. [Order of Operations] Evaluate:                                                                      R = $15,720

Tan3A=tan(2A+A)

We know that , tan(x+y)=(tanx + tany)/(1 - (tanx)(tany))

tan(2A+A)=(tan2A+tanA)/(1 - (tan2A)(tanA))— (1)

We know that , tan2x=2tanx/(1 - tan^2x)

So, by substituting tan2A in (1),we get,

=[2tanA/(1 - tan^2A) + tanA]/1- (2tanA/(1 - tan^2A))(tanA)]

=[2tanA+tanA - tan^3A]/[1 - tan^2A - 2tan^2A]

=[3tanA - tan^3A]/[1-3tan^2A]

Therefore, tan3A= [3tanA - tan^3A]/[1-3tan^2A]
