Answer:
80 ft
Step-by-step explanation:
We are given two similar triangles ABC and DFG
When two triangles are similar then the ratio of their corresponding sides are equal.
AB=4 ft
BC=5ft
AC=7 ft
DF=20 ft
FG=25 ft
Perimeter of DFG=DF+FG+DG=20+25+35=80 ft
Hence, she would need fence for triangle DFG=80 ft
If Wilson produces only one 1 bag, then his profit starts decreasing
<h3>How to determine the point</h3>Given the function;
Let f ( x ) =
Where;
x is the number of bags of cereal produced
Factorize the expression
If the value of x is decreasing, we have;
f ′ ( x ) ≤ 0
4x² (2x - 3) ≤ 0
If x² ≥ 0, then;
2x - 3 ≤ 0
x ≤ 3/ 2
With x as the number of bags
x ∈ N
x = 1 is the only possibility
Thus, if Wilson produces only one 1 bag, then his profit starts decreasing

The complete question:
Wilson hires a financial analyst to analyse costs and profits for his cereal production business. The analyst determines that Wilson’s eventual profit function is given as: pi = 2x ^ 4 - 4x ^ 3 + 7, where x is the number of bags of cereal produced. At what point or number of bags of cereal will Wilson’s profit start decreasing
