She spent $7.44 because 3.28 + 1.27 + 0.56 + 2.33 = 7.44
Given:
The function is

To find:
The zeros of the given function.
Solution:
The general form of polynomial is
...(i)
where, a is a constant,
are zeros of respective multiplicities
.
We have,

On comparing this with (i), we get


It means, -3 is a zero with multiplicity 2 and 5 is a zero with multiplicity 6.
Therefore, the correct option is B.
Answer:
56.02 dollars
Step-by-step explanation:
Wanted x, the price before taxes and tip.
sales tax: x * 0.11
+
tip on sales tax: x * 0.11 * 0.2
+
tip on price: x * 0.2
= 0.332x
= 18.6 (presumption)
Therefore,
x = 18.6/0.332 = 56.02
