To solve this problem you must follow the proccedure shown below:
1. You have that <span>the pasture must contain 128 square meters and no fencing is required along the river. Then:
A=LxW
A is the area
L is the lenght
W is the width
2. Let's clear W:
W=A/L
W=128/L
3. The formula of the perimeter is:
P=2L+W
P=2L+(128/L)
4. Now, you must derivate:
dP/dL=0
2+(128/L</span>²)=0
<span> L=8 meters
W=A/L
W=128/8
W=16 meters
</span>

Answer:
58.50
Step-by-step explanation:
First find out how many were vanilla and chocolate
vanilla: 5/6 * 36 = 30
Chocolate = total - vanilla = 36-30 =6
Cost for vanilla = 1.50*30 =45
Cost for chocolate 2.25*6 =13.5
Add the cost together
45+13.50
58.50
Option B: 50 is the value of the constant.
Explanation:
From the graph, the coordinates are
,
,
and 
Where the x coordinates denotes the width and the y - coordinates denotes the height.
Also, given that 
We need to determine the value of the constant
<u>Value of the constant:</u>
The value of the constant can be determined using the formula,

Since, all the coordinates lie on the same line, then all the coordinates have the constant.
Substituting the coordinate
in the above formula, we get,


Therefore, the value of constant is 50.
Hence, Option B is the correct answer.
