Now
(Calculation of this it too long and it is hard to type on brainly)
here is the answer though....
= 4/5
=0.8
To find the optimized value you need to find where the vertex(tip) of the parabola
use
to find the optimized x value
y= -w^2 +100w + 0
x = 50
answer: 50
Answer:
Last Year Length = 4 meters
This Year Length = 12 meters
This Year Width = 10 meters
Step-by-step explanation:
We know, area of the rectangle is given by the formula:
Area = Length * Width
Given width = 5
Area = 20
We solve for Length:
Area = Length * Width
20 = Length * 5
Length = 20/5 = 4
Last Year Length = 4 meters
Now, this year, the length would be 3 times as long, so new length would be:
This Year Length = 4 * 3 = 12 meters
This year, the width would be two times previous year, so width would be:
This Year Width = 5 * 2 = 10 meters
