The rate of change is 8/6.
Assume w is the width. the length is 3*2w
To fence the whole outside of farm, he needs:
2(w+6w)=14w meters
Also he needs one width and one length for the enclosed pens. Therefore, the total amount of fencing he would need:
14w+w+6w=21w meters
Answer:
Step-by-step explanation:
This parabola is a horizontal one.
In the more familiar case, vertical parabolas, the applicable equation is:
y - k = a(x - h)^2, where (h, k) is the vertex and 'a' has to do with vertical compression or stretching.
For the horizontal parabola, we adapt the above formula to:
x - h = b(y - k)^2
substituting -17 for x and 2 for k:
x + 17 = b(y - 2)^2
Because the parabola opens to the left, b must be negative. One of many examples would be:
x + 17 = -2(y - 2)^2, where the choice of 'b' is arbitrary.
