10^2=100.
100x18.72=1872
10 to the second power is 100
when you multuply by 100 you basically just move the decimal place forward 2 decimal places. Essentially the same as:
100x18.72
10x187.2
1x1872
Answer:
perpendicular; their slopes are opposite reciprocals
Step-by-step explanation:
y = (2/3)x + 8
rewrite the first equation to be in point-slope form
3x + 2y = 7
2y = -3x + 7
y = (-3/2)x + (7/2)
their slopes are (2/3) and (-3/2) -- opposite reciprocals
R; all quadratic functions are going to have ranges and domains of *ALL REAL NUMBERS*.
