In the project considered below, activity crashing can take place over a widerange of reduction times. The cost per day of reduction is given:ActivityImmediateNormal TimeCost/dayLower TimePredecessor(days)LimitANone34501BNone43002A3200DE100EA,B5001FC.D46003For example, activity C can be crashed from its normal time of 3 days down to aslittle as 1 day or anywhere in between; the cost per day to crash C is 200.a) Draw a network diagram for this project. What is the critical path? How longwill the project take, if no crashing takes place?b) Determine the least cost way to crash activities in order to complete theproject in 11 days; in 10 days; in 9 days; in 8 days.c) Suppose the due date for the project is 5 days and a penalty of $500 a day isassessed for each day late. What is the optimal number of days to crash theproject? Why?

Can i get help with the question below please and thank you 16) This could be a rover, probe/satellite, manned mission, telescope, etc. This mission must be accomplished using technology that is available today (no Warp or Epstein drives) and must be accomplished within your lifetime. Your mission will not be a copy of a real mission. Constraints: ▪ Answer using the underlined subheadings at each point below (Mission Objective, Target, Instrumentation), marks will be deducted for poorly organized answers. ▪ You target must be reachable by whatever you are sending within a human lifetime (~75 years), it would be nice to visit Gliese 581c, but it is 20 light years from Earth so for now it is unreachable. What this means is that you are constrained to our solar system except for telescopes that peer into the universe or a probe getting to interstellar space. ▪ If your mission includes sending humans, then we need to estimate a reasonable limit on how far we can send humans.
