From information given Lisa bought three items.
10 + 20 + 23 = 53 dollars ( which is total pre- tax cost)
The sales tax rate is at 7.2% . Value of this tax in dollars will be:
7.2 % of 53 → (7.2 / 100) × 53 → 0.072 × 53 = 3.816
So the tax rate value is 3.816
Total cost of items will be 53 + 3.816 = 56. 816
Rounded off to the nearest cent 56.816 = 56.80
Therefore Lisa paid a total of $ 56.80
The maximum number of relative extrema of the given polynomial is; 3
<h3>How to find the maxima of a Polynomial Function?</h3>
When trying to find the maximum number of relative extrema of a polynomial, we usually use the formula;
Maximum number of relative extrema contained in a polynomial = degree of this polynomial - 1.
We are given the Polynomial as;
f(x) = 3x⁴ - x² + 4x - 2
Now, the degree of the Polynomial would be 4. Thus;
Maximum number of relative extrema = 4 - 1
Maximum number of relative extrema = 3

D is the diameter of the wheel
the circle is π.d = 180
so d = 180/π = 57 cm
Balance after 6 months would be 900*(900+2%). You just need to evaluate it then you will get the answer. btw 2% comes from 4% because it's half of the year.
Answer: Tom
Step-by-step explanation:
Tom did 1/3 of 30= 10 out of 30
Steven did 3/10 of 30= 9 out of 30
Juan did 20/100 of 30= 6 out of 30
Marcus did 8 out of 30
