Answer:

A y < -1/2

Step-by-step explanation:

4/3 < -8/3 y

Multiply both sides by 3

3×4/3 < 3× -8/3 y

4 < - 8y

Divide both sides by -8

4/-8 > -8y/-8

The inequality sign changes by dividing by negative

-1/2 > y is same as y < -1/2

Therefore

y < -1/2

A bucket that weighs 4 lb and a rope of negligible weight are used to draw water from a well that is 60 ft deep. The bucket is f

jonny [76]

Answer:

2580 ft-lb

Step-by-step explanation:

Water leaks out of the bucket at a rate of $\frac{0.15 \mathrm{lb} / \mathrm{s}}{1.5 \mathrm{ft} / \mathrm{s}}=0.1 \mathrm{lb} / \mathrm{ft}$

Work done required to pull the bucket to the top of the well is given by integral

$W=\int_{a}^{b} F(x) dx$

Here, function $F(x)$ is the total weight of the bucket and water $x$ feet above the bottom of the well. That is,

$F(x)=4+(42-0.1 x)$

$=46-0.1x$

$a$ is the initial height and $b$ is the maximum height of well. That is,

$a=0 \text { and } b=60$

Find the work done as,

$W=\int_{a}^{b} F(x) d x$

$=\int_{0}^{60}(46-0.1 x) dx$

$&\left.=46x-0.05 x^{2}\right]_{0}^{60}$

$=(2760-180)-0[$

$=2580 \mathrm{ft}-\mathrm{lb}
$

Hence, the work done required to pull the bucket to the top of the well is $2580 \mathrm{ft}- \mathrm{lb}$

F(1)=−2<br> f(2)=5<br> f(n)=f(n−2)⋅f(n−1)<br> f(3) = ?

3241004551 [841]

<h3>Answer: -10</h3>

Work Shown:

f(n) = f(n-2)*f(n-1)

f(3) = f(3-2)*f(3-1)

f(3) = f(1)*f(2)

f(3) = -2*5

f(3) = -10
