Answer:
The boat is approaching the dock at rate of 2.14 ft/s
Step-by-step explanation:
The situation given in the question can be modeled as a triangle, please refer to the attached diagram.
A rope attached to the bow of the boat is drawn in over a pulley that stands on a post on the end of the dock that is 5 feet higher than the bow that means x = 5 ft.
The length of rope from bow to pulley is 13 feet that means y = 13 ft.
We know that Pythagorean theorem is given by

Differentiating the above equation with respect to time yields,


dx/dt = 0 since dock height doesn't change


The rope is being pulled in at a rate of 2 feet per second that is dz/dt = 2 ft/s
First we need to find z
z² = (5)² + (13)²
z² = 194
z = √194
z = 13.93 ft
So,



Therefore, the boat is approaching the dock at rate of 2.14 ft/s
Answer: 439,824 ft
Step-by-step explanation: the | means it is equal to so there is one on 7ft so the one without a number will be 7ft
Area is LxW
so 7x6x8x11x17x7=439,824
not sure if it’s correct tho but i guess I helped

this will help you
For an increase of 15% you would add the increase percentage to 1 and multiply that by number of years.
So the multiplication rate would be 1.15
The answers are cut off in the picture, but the one with 1.15 is the top left answer.
