Step-by-step explanation:
A third degree polynomial has a <em>total of three roots</em>, real and imaginary combined.
If it already has 2 real roots, -4 and +4, then it has to have three real roots because imaginary roots come in conjugate pairs, i.e. they come in even numbers.
So 140 is the simple interest fee of 8% so 8% that her friend is charging her is only 140. So you can add that to the original price to know ALL of what she is gonna pay but that depends of you just want the fee or the whole total which is 1890
This problem involves using the Pythagorean Theorem which is a^2+b^2=c^2
We already have the values of a and c, but b is unknown. So we plug in: 11^2+b^2=20^2
121+b^2=400
b^2=279
b=sqrt(279)
b=16.7
So the answer is about 16.7 ft
Hope this helped!
