Each x requires 2 of component y; each y requires 4 of part z. the lead time for assembly of x is 1 week. the lead time for the manufacture of y is 1 week. the lead time for the procurement of z is 6 weeks. the cumulative lead time for x is weeks.
a. 48
b. 7
c. 8
d. 10

C.

Step-by-step explanation:

The cumulative lead time for manufacturing is equal the manufacturing Lead Time + Procurement Lead Time (for raw materials, components, and subassemblies) + Shipping Lead Time

Therefore cummulative lead time = 1+6+1 = 8 .

Shipping time is not considered or assumed to be zero .

true

step-by-step explanation:

f(x) = x^3 -2x^2 -3x

x( x^2 -2x-3)

x( x^2 +x -3x -3)

x( x(x+1) -3(x+1))

x( x-3)( x+1)

so zeroes are 0, 3,-1
