A bucket that weighs 3 lb and a rope of negligible weight are used to draw water from a well that is 90 ft deep. The bucket is f

Lisa [10]

Answer:

a) Lim(0-inf) Work = (36 - 0.1*xi )*dx

b) Work = integral( (36 - 0.1*xi ) ).dx

c) Work = 2835 lb-ft

Step-by-step explanation:

Given:

- The weight of the bucket W = 3 lb

- The depth of the well d = 90 ft

- Rate of pull = 2.5 ft/s

- water flow out at a rate of = 0.25 lb/s

Find:

A. Show how to approximate the required work by a Riemann sum (let x be the height in feet above the bottom of the well. Enter xi∗as xi)

B. Express the Integral

C. Evaluate the integral

Solution:

- At time t the bucket is xi = 2.5*t ft above its original depth of 90 ft but now it hold only (36 - 0.25*t) lb of water at an instantaneous time t.

- In terms of distance the bucket holds:

( 36 - 0.25*(xi/2.5)) = (36 - 0.1*xi )

- Moving this constant amount of water through distance dx, we have:

Work = (36 - 0.1*xi )*dx

The integral for the work done is:

Work = integral( (36 - 0.1*xi ) ).dx

Where the limits are 0 < x < 90.

- Evaluate the integral as follows:

Work = (36xi - 0.05*xi^2 )

- Evaluate limits:

Work = (36*90 - 0.05*90^2 )

Work = 2835 lb-ft

Carrie borrowed $720 from a friend to pay for a car repair. Carrie promises to repay her friend in 8 equal

shutvik [7]

The graph represents a linear function.

The amount left to pay after the eight month is (d) (8,y)

From the question, we have:

$\mathbf{Loan\ Amount =\$720}$

$\mathbf{Months =8}$

On the graph, we have the following observations

The x-axis represents the number of months
The y-axis represents the amount left to pay

So, the amount left to pay, after the first month is (1,y) -- as seen on the graph

Similarly, the amount left to pay after the eight month would be (8,y)

Hence, the true option is: (d) (8,y)
