Answer:
<em>The ferry can travel 
of the distance between the two ports in one hour.</em>
Step-by-step explanation:
A ferry traveled 
of the distance between two ports in 
hour.
Suppose, the ferry traveled 
of the distance between the two ports in one hour.
So, the <u>equation according to the ratio of "distance" to "time"</u> will be.......
Thus, the ferry can travel of the distance between the two ports in one hour.
Let's first define the variables:
x = width
300 - 2x = long
The area will be:
A = (x) * (300 - 2x)
A = 300x - 2x²
We look for the maximum area, for this, we derive:
A '= 300 - 4x
We match zero:
0 = 300 - 4x
x = 300/4 = 75
Therefore, the width is:
x = 75 feet
The length is:
300 - 2x = 300 - 2 (75) = 300-150
150 feet
Answer:
Part A:
The maximum area will be:
A = (150) * (75) = 11250 square feet
Part B:
The dimensions are:
Length = 150 feet
width = 75 feet
Answer:
Step-by-step explanation:
The system would be:
And I attached the graph. The system will have 2 solution (The 2 intercepts between the curves)
Answer:
4-7
this gives us answer of -4
