Answer:

$32.80

Step-by-step explanation:

Find out how much Nancy spent on 4 violins and 2 song books.

1 violin = 87.82

4 violins = 87.82 x 4 = 351.28

1 song book = 7.96

2 song books = 7.96 x 2 = 15.92

351.28 + 15.92 = 367.20

4 x 100 dollar bills = 400 dollars

Normally after paying for an item, if you pay much more money than the actual price of the item, you'll get some money back from the cashier. That's called a change.

400 - 367.20 = 32.80

What is the maximum number of relative extrema a polynomial function can have?
creativ13 [48]
Relative extrema occur where the derivative is zero (at least for your polynomial function). So taking the derivative we get

<span>20<span>x3</span>−3<span>x2</span>+6=0

</span><span> This is a 3rd degree equation, now if we are working with complex numbers this equation is guaranteed to have 3 solutions by the fundamental theorem of algebra. But the number of real roots are 1 which can be found out by using Descartes' rule of signs. So the maximum number of relative extrema are 1.</span>
