Justin wants to use 188ft. Of fencing to fence off the greatest possible rectangular area for the garden. What dimensions should he use what will be the area of the garden

Answers

Answer 1

Answer: Hello,

Let x the length
y the width

2*(x+y)=188 ==>x+y=94
A= x*y must be maximized

A=x*(94-x)=-(x²-2*47*x+47²)+47²=-(x-17)²+2209
A est maximize if x=47
x=47 =>y=94-47=47 (a square!!!)
Area=47²=2209 (ft²)

In a hydraulic system, piston 1 has a surface area of 100 cm2, and piston 2 has a surface area of 900 cm2. Piston 1 exerts a pressure of 10 Pa on the fluid in the hydraulic lift.What is the fluid pressure on piston 2?

Answers

By hydraulic principles the pressures are equal.

Then pressure on piston 2 = pressure on piston = 10 Pa.

That is what permits to apply a low force on the surface of the piston with the smaller area and get a bigger force on sureface of the piston with the greater area.

Answer:10 Pa
