The label on a ceiling lighting fixture warns you to use a lightbulb of 60 watts or less. the voltage to the

lightbulb is 120 volts. an intern calculated how much amperage a bulb of the maximum allowed wattage

will draw. you are checking her work, shown below. if there is an error, what is the first step that has an

error, and why is it an error?

(- 1, 0 )

step-by-step explanation:

an x- intercept is where the function crosses the x- axis.

to find the x- intercept/s look for the value of x when f(x) = 0

from the given table there are 3 values of x where f(x) = 0

when x = - 1, x = 2, x = 3

the one that is listed is (- 1, 0 )

30005

yes ok                                            

step-by-step explanation:

no, her answer is not correct.   we square the lengths of all sides and then determine whether the pythagorean theorem holds here:

9² + 15² = 306.   this is not equal to the square of the longest side ( that square being 395.   answer c is correct.
