The length of the second copper wire is 1250.4 feet.

Step-by-step explanation:

The length of the first wire, = 750 feet.

Resistance of the first wire, = 1.893 Ω

The length of the second wire =

Resistance of the second wire, = 3.156 Ω

The length of the second wire can be determined by the relation;

=

=

=

   =

= 1250.3962

   = 1250.4

The length of the second copper wire is 1250.4 feet.

step-by-step explanation:

in the absence of parentheses, i will have to make some assumptions:   i interpret your (3x+5/y^6)(4y^3/5)​ to mean:

3x + 5     4y^(3/5)       (3x + 5)(4)

* =

    y^6             1               y^(6-3/5)

if this is not what you expected, repost your question using parentheses to indicate whether you meant

4y^3

    or   4y^(3/5)

the dimensions are:

step-by-step explanation:

we want to find the dimensions of a rectangular box with volume of

we factor to obtain;

we rewrite the rightmost factor to obtain;

recall that:

we apply difference of two squares formula to obtain;

hence the dimensions are
