Find the work done in winding up a 175 ft cable that weighs 3 lb/ft.
nignag [31]

Answer:

work \ done= 45937.5

Step-by-step explanation:

Work done is given by

work \ done=\int_a^b w(d-x) \ dx , where d = length of cable and w = weight of cable.

Here, d = 175 ft and w = 3 lb/ft

Now, work \ done=\int_0^{175} 3(175-x) \ dx

work \ done= 3\left [175x-\frac{x^2}{2}  \right ]_0^{175}

work \ done= 3\left [175^2-\frac{175^2}{2}  \right ]

work \ done= 3\cdot \frac{175^2}{2}

work \ done= 45937.5

3) Expresa mediante una fórmula la función que a un número entero x le hace corresponder el doble del número siguiente a x. Haz
jonny [76]

Answer: The function is: f(x) = 2*(x +1)

Step-by-step explanation:

This can be translated to:

"write an equation of a function where a whole number x corresponds to the next number to x"

the next whole number to x is x+1., and we want the double of that.

Then we have that our function is:

f(x) = 2*(x +1)

Now we can do a little table of it:

f(0) = 2*(0 + 1) = 2

f(1) = 2*(1 + 1) = 4

f(2) = 2*(2+ 1) = 6
