what's the population in 2004? well, from 1994 to 2004 is 10 years later, so t = 10
plug that in, to get P for 2004
The measurement of the missing angle is 90 - 61 = 29°
Just answer it correctly and you won’t have to be confused:)))
When an interval says (0, 2pi). This means all angles ranging from 0 to 2pi with 0 and 2pi not included in the values. The parenthesis means the values in the right or left of it is not included while a bracket is used to indicate the values used as limits are included
You can set it up as an equation:
29.95x + 2x
then plug in x = 7.
I'm not sure how this really relates to the distributive property though.
