If you look at the sine curve,
you'll find the curve passing through x axis,
firat at x=0, and then at x =pi.
hence, after 0, next radian value for which sin x = 0 is x = pi
Parallel to the y axis...that would mean that it is a vertical line.
The equation would be : x = 4 and it would have an undefined slope

Answer: Approximately -0.0742857 grams per year</h3>
======================================================
Work Shown:
x = year
y = amount of hydrocarbon emissions in grams, per mile driven
m = rate of change = slope
m = (y2 - y1)/(x2 - x1)
m = (0.8 - 3.4)/(2007 - 1972)
m = -2.6/35
m = -0.0742857 approximately
The approximate rate of change is about -0.0742857 grams per year. The negative rate of change indicates the per mile hydrocarbon amount has gone down by about 0.0742857 grams each year.
Answer: C
<u>Step-by-step explanation:</u>
(x - 3)² = 0
(x - 3)(x - 3) = 0
x(x - 3) -3(x - 3) = 0
x² - 3x -3x + 9 = 0
x² - 6x + 9 = 0
