Answer:
<em>-1.031 m/s or </em>
Step-by-step explanation:
We take the length of the rope from the dock to the bow of the boat as y.
We take x be the horizontal distance from the dock to the boat.
We know that the rate of change of the rope length is
= -1 m/s
We need to find the rate of change of the horizontal distance from the dock to the boat =
= ?
for x = 4
Applying Pythagorean Theorem we have
.... equ 1
solving, where x = 4, we have



Differentiating equ 1 implicitly with respect to t, we have

substituting values of
x = 4
y = 
= -1
into the equation, we get

= <em>-1.031 m/s</em>
1. The information, given in the problem, that you need to solve it, is:
- <span>A steel bar that originally weighed 15.62 pounds.
- Then i</span><span>t weighs 14.48 pounds.
2. Therefore:
15.62 pounds-----100%
14.48 pounds-----x
x=(14.48)(100)/15.62
x=92.70%
3. Now, you must substract both percents:
=100%-92.70%
=10.38%
The answer is: 7.3%
