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
<em><u>The system of linear inequalities are:</u></em>
<em><u>Solution:</u></em>
Let "a" be the number of small candles bought
Let "b" be the number of large candles bought
<em><u>He needs to buy at least 20 candles</u></em>
Therefore, number of small candles and number of large candles bought must be at least 20
Thus, we frame a inequality as:
"at least" means greater than or equal to
Here, we used "greater or equal to" symbol because, he can buy 20 candles or more than 20 candles also
From given,
Cost of 1 small candle = $ 2.50
Cost of 1 large candle = $ 7
<em><u>He can spend no more than 80 dollars</u></em>
Which means, he spend maximum 80 dollars or less than 80 dollars also
So we have to use "less than or equal to" symbol
<em><u>Thus, we frame a inequality as:</u></em>
Number of small candles bought x Cost of 1 small candle + number of large candles bought x Cost of 1 large candle 80
<em><u>Thus the system of linear inequalities are:</u></em>
