There would be 450 rabbits last year.
Since 900 is double 450, 200% of 450 is 900. (450 would be 100%, so you would double it).
3/4 divides by 1/7 =
copy dot flip
3/4 * 7/1
21/4
4 goes into 21 5 times with 1 left over
5 1/4

Pi/3 is equivalent to 60 degrees, as 2pi is equal to 360 degrees. cos(60) in a triangle yields 1/2, and sin(60) yields (3^(1/2))/2. Thus, -pi/3, or -60 degrees would be a fourth quadrant point on the unit circle and these values would be negative as well, at cos(-pi/3)=-1/2 and sin(-pi/3)=-(3^(1/2))/2
The answers are
a) the domain is all real numbers
d) the input to an exponential function is the exponent
e) the base represents the multiplicative rate of change
hope this helps :)
