Aperson in good physical condition can put out 100 w of useful power for several hours at a stretch, perhaps by pedaling a mechanism that drives an electric generator. neglecting any problems of generator efficiency and practical considerations such as resting time: (a) how many people would it take to run a 4.00-kw electric clothes dryer?

40 persons

Step-by-step explanation:

Data provided :

The power put out by a single person = 100 W

Power required by an electric clothes dryer = 4.00 kW = 4000 W

Thus,

The number of persons required to produce 4000 W of power

= ( Power required ) / ( power produced per person )

or

= (4000 W) / (100 W/ person)

or

= 40 persons

Hence, the number of persons required is 40

(x3 + 6x2 + 2x - 6) • (x - 1)

step-by-step explanation:

polynomial long division :

3.2     polynomial long division

dividing :   x4+5x3-4x2-8x+6

                              ("dividend")

by         :     x-1     ("divisor")

dividend     x4   +   5x3   -   4x2   -   8x   +   6

- divisor   * x3     x4   -   x3            

remainder         6x3   -   4x2   -   8x   +   6

- divisor   * 6x2         6x3   -   6x2        

remainder             2x2   -   8x   +   6

- divisor   * 2x1             2x2   -   2x    

remainder               -   6x   +   6

- divisor   * -6x0               -   6x   +   6

remainder                     0

quotient :   x3+6x2+2x-6   remainder:   0
