In forestry management it is important to know the net stumpage value of a stand (that is, a group) of trees. This is the commercial value of the trees minus the costs of felling, hauling, etc. The graph in the figure shows the net stumpage value V, in dollars per acre, of a Douglas fir stand in the Pacific Northwest as a function of the age t, in years, of the stand.†
$
(b) Estimate the age of a Douglas fir stand whose net stumpage value is $20,000 per acre.

Loci, How much rope is needed and where do I put the posts? Mathematics Assignment Help
A rectangular field measuring 17.5 metres by 10 metres has two posts 7.5 metres apart with a ring on top of each post. The posts are approximately 7 metres from the nearest corners as shown in the diagram. You have two quarrelsome goats and plenty of ropes which you can tie to their collars and you want them to be able to graze the whole field between them. How can you secure them, using the posts, so they can’t fight each other, and how much rope is needed?
Need an answer really quickly! If more information is needed (There is a diagram too) go to http://nrich.maths.org/597

Calculate the fluid velocity in ft/sec to 2 decimal places. The formula for the Engineering Assignment Help
Calculate the fluid velocity in ft/sec to 2 decimal places. The formula for the velocity is given by:
velocity =Flow rate / Pipe Area
The flow rate = 53 gpm
and the Pipe Area is calculated from its diameter of 8 inches,
231 cubic inches = 1 gallon,
12 inches = 1 ft, and
60 sec = 1 minute

Absolute values of inequalities Mathematics Assignment Help
i solved the equation  2x + 7  + 5 > 10
subtracted 5 :  2x + 7  + 55 > 105
got: 2x+7 > 5
subtracted 7: 2x + 77 =57
got: 2x> 2
divided by 2: 2x/2 > 2/2
answer: x > 1
Then i did  2x + 7  5 > 10
added 5: 2x + 7  5 + 5 > 10 + 5
got: 2x + 7 > 5
subtracted 7: 2x + 77 > 57
got: 2x > 12
divided by 2: 2x/2 > 12/2
got: x < 6
my question is why did the sign change for x<6 and not for x>1 since they are both negative?
