Hey there...
Critical path analysis is a technique that identifies the activities necessary to complete a task, including identifying the time necessary to complete each activity and the relationships between the activities.
I couldn't get an example for it but here are the steps:
1. Divide the project into tasks
2. Estimate tasks
3. Create the network diagram
4. Draw initial Gantt (bar) chart
5. Perform resource levelling
6. Compress the schedule (if necessary).
Hope it helps...
Answer:
Step-by-step explanation:
The area of a rectangle can be found with the formula
, where
is the length of the rectangle and
is the width.
From the given problem statement, we know that
and
, so we can fill in those values in the formula anbd solve for
to get the width:
![A = l*w](https://tex.z-dn.net/?f=A%20%3D%20l%2Aw)
![161 = 14w](https://tex.z-dn.net/?f=161%20%3D%2014w)
Divide both sides by
to isolate
by itself:
![\frac{161}{14} = \frac{14w}{14}](https://tex.z-dn.net/?f=%5Cfrac%7B161%7D%7B14%7D%20%3D%20%5Cfrac%7B14w%7D%7B14%7D)
![w = 11.5](https://tex.z-dn.net/?f=w%20%3D%2011.5)
Answer:
The maximum height that the ball will reach is 81 ft
Step-by-step explanation:
Note that the tray of the ball is given by the equation of a parabola of negative main coefficient. Then, the maximum value for a parabola is at its vertex.
For an equation of the form
![at ^ 2 + bt + c](https://tex.z-dn.net/?f=at%20%5E%202%20%2B%20bt%20%2B%20c)
So
the t coordinate of the vertice is:
![t =-\frac{b}{2a}](https://tex.z-dn.net/?f=t%20%3D-%5Cfrac%7Bb%7D%7B2a%7D)
In this case the equation is:
![h(t)=72t-16t^2](https://tex.z-dn.net/?f=h%28t%29%3D72t-16t%5E2)
So
![a=-16\\b=72\\c=0](https://tex.z-dn.net/?f=a%3D-16%5C%5Cb%3D72%5C%5Cc%3D0)
Therefore
![t =-\frac{72}{2(-16)}](https://tex.z-dn.net/?f=t%20%3D-%5Cfrac%7B72%7D%7B2%28-16%29%7D)
![t=2.25\ s](https://tex.z-dn.net/?f=t%3D2.25%5C%20s)
Finally the maximum height that the ball will reach is
![h(2.25)=72(2.25)-16(2.25)^2](https://tex.z-dn.net/?f=h%282.25%29%3D72%282.25%29-16%282.25%29%5E2)
![h=81\ ft](https://tex.z-dn.net/?f=h%3D81%5C%20ft)
Answer:
Commutative Property
Step-by-step explanation:
1. The commutative property is a mathematical law that states that the order in which we multiply numbers does not change the product. Because a × m results in the same answer from multiply m × a, it falls under this property.
