Calculate ROR.... (see attachment for full questions) I need to get some outline on a step by step method to solve the problem(s). Some of them involve optimisation.
It may be the mental picture that's confusing me, but I can't figure this one out: "A painting in an art gallery has height h and is hung so that its lower edge is a distance d above the eye of an observer. How far from the wall should the observer stand to get the best view? (In other words, where should the observer stand
A car travels at a constant speed of 70km per hour for a time of 2 hours and 45 minutes. Its speed is quoted to the nearest km/h and the time is quoted to the nearest minute. Calculate: a) the maximum possible distance that the car could have travelled b) the minimum distance the car could have travelled
The Satellite Mission Scheduling problem with Dynamic Tasking (SMS-DT) involves scheduling tasks for a satellite, where new task requests can arrive at any time, non-deterministically, and must be scheduled in real-time. The schedule is a time ordered sequence of activities (scheduled tasks) to be performed by the payload of a s
F(x)=ln((x^4)+27) (a)Find the intervals of increase and decrease. (b)Find the local maximum and minimum values. (c)Find the intervals of concavity and inflection points. (d)Use the information from (a)-(c) to sketch the graph.
4. Let a function f be continuous in a closed bounded region R, and let it be analytic and not constant throughout the interior of R. Assuming that f(z) does not equal 0 anywhere in R, prove that f(z)f has a minimum value n in R which occurs on the boundary of R and never in the interior. Do this by applying the corresponding re
