Answer:

x^3 + 1/x^3 = 488

Step-by-step explanation:

x^2 + 1/x^2 = 62
x^2 + 1/x^2 + 2 = 64
( adding 2 in both sides )
(x + 1/x ) ^2 = 64
x + 1/x = 8

now,

( x+ 1/x ) ^ 3 = 512
x^3 + 1/x^3 + 3 × x × 1/x ( x + 1/x )
x^3 + 1/x^3 + 3 ( 8 )
( since x + 1/x = 8 )
x^3 + 1/x^3 + 24 = 512
x^3 + 1/x^3 = 488

hence, we got x^3 + 1/x^3 = 488

Answer:

As shown in picture, we have

$v = \frac{8\sqrt{3}}{cos 30} = \frac{8\sqrt{3}}{\frac{\sqrt{3}}{2} } = 16$

Hope this helps!

:)

Explanation:

Let say right triangle ABC has A = 90 deg.

=> BC is hypotenuse.

=> BC = AC x BC/AC = AC/(AC/BC) =AC/cosC.

That's the way we've done!

The BJ Electrical Company needs to hire master electricians and apprentices for a one week project. Master electricians receive

Stells [14]

Answer:

The BJ Electrical Company

The BJ Electrical Company should hire:

8 master electricians and

22 apprentices

in order to accomplish the project and still meet the contract safety requirements.

Step-by-step explanation:

Number of workers needed = 30

Class of workers:

Master electrician, with per week salary = $750 per worker

Apprentices, with per week salary = $350 per worker

Number of inspection hours required from each master electrician = 3 hours

Total inspection hours for the project = 25 hours

Average number of master electricians needed = 25/3 = 8.333 = 8

Number of each type of worker needed:

Master electricians = 8

Apprentices = 22 (30 - 8)

Cost to be incurred for workers:

Master electricians = $6,000 (8 * $750)

Apprentices = 7,700 (22 * $350)

Total labor cost = $13,700

First, categorize each fraction. So like this. Just write it out.

1/2,1/2,1/8,1/8,3/8,3/16,5/16,5/16,5/16,5,16

Then, plot the points according to where each number goes.
