The points plotted below are on the graph of a polynomial. In what range of x-values must the polynomial have a root?

1 answer:

6 0

Actually, I think the question should be, "In what range(s) of x-values must there be a root of the POLYNOMIAL?" Unless you are working with some real strange maths, polynomials are smooth and continuous. If you drew a smooth and continuous line through the points in the graph, where would the line have to cross the x-axis?

What is the selling price of an item if the original cost is $784.50 and the markup on the item is 6.5 percent?

kotegsom [21]

Answer:

835.49

Step-by-step explanation:

selling price = original cost + markup value

We need to find the markup

markup = original cost * markup percent

= $784.50 * 6.5%

= $784.50 *.06.5

=50.9925

Rounding to the nearest cent

=50.99

selling price = original cost + markup value

=784.50+50.99

835.49
