Answer:
NL = 4.33
NM = 5
Step-by-step explanation:
tan 60° = NL/2.5
tan 60° = 1.7321
so:
1.7321 = NL/2.5
NL = (2.5)(1.7321)
NL = 4.33
cos 60° = 2.5/NM
cos 60° = 0.5
so:
0.5 = 2.5.NM
NM = 2.5/0.5
NM = 5
Answer:
A function that gives the work required in foot-lbs to lift the bucket up x feet from the ground is
and the work to get the bucket to the top of the cliff is 3726 foot-lbs
Step-by-step explanation:
Work done to lift the rope by distance x feet:

Work done to lift the bucket by distance x feet:

On reaching top 7 gallons of water spilled out so , on going up by x feet
gallons of water spilled out.
a function that gives the work required in foot-lbs to lift the bucket up x feet from the ground:

Now the work to get the bucket to the top of the cliff i.e. x =35

W=3726
Hence, a function that gives the work required in foot-lbs to lift the bucket up x feet from the ground is
and the work to get the bucket to the top of the cliff is 3726 foot-lbs
4.16667 yd.
288 in.
2.5 miles
hope this helps!
