k<2(3.5) or simplified k<7
Well to do scientific notation u have to use 10 then an exponent
example:
2.9867 x 10^10= 29,867,000,000
so u need exponents to do scientific notation.
2:1 is the ratio
- Rach :)
The rate of change is
(2- (-1))/ (3/2-(-4)) => 3 / (11/2)
that is equal to 6/11 so almost 1/2
