2 answers:
Answer:
£57.6
Step-by-step explanation:
Given :The pen must have a perimeter of 24 m
Every half meter of fencing costs him £1.20
To Find : Work out the cost of the fence used to make the sheep pen.
Solution :
Cost of fencing 0.5 m = £1.20
Cost of fencing 1 m =
The pen must have a perimeter of 24 m
So, cost of fencing 24 m =
Hence the cost of the fence used to make the sheep pen is £57.6

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
For this case we find the slopes of each of the lines:
The g line passes through the following points:
So, the slope is:
Line h passes through the following points:
So, the slope is:
By definition, if two lines are parallel then their slopes are equal. If the lines are perpendicular then the product of their slopes is -1.
It is observed that lines g and h are not parallel. We verify if they are perpendicular:
Thus, the lines are perpendicular.
Answer:
The lines are perpendicular.
