Determine the length of the flag
Because the flag crosses through opposite diagonals of the pool. Its length is the length of the diagonal of the pool.
This is calculated using Pythagoras theorem.

Substitute values for Length and Width



Take positive square root of both sides


<em>Hence, the length of the flag is approximately 55.90m</em>
Rate = A ratio that compares two quantities measured in different units.
Unit Rate = A rate in which the second quantity in the comparison is one unit.
The polynomial of least possible degree having the graph as given is; f(x) = x³-8x²+x +42.
<h3>Polynomial of least possible degree</h3>
It follows from the graph that the roots of the polynomial are; -2, 3 and 7.
On this note, the factors of such polynomial are;
Hence; (x+2)(x-3)(x-7) = f(x)
