The is a decimal number that can be converted to a mixed fraction
2.16 = 2 + 0.16
2 = whole number.
So, we are left with 0.16
We can convert this to a fraction
Since it is in 2 decimal places we Multiply by 100
=( 0.16 × 100)/ 100
= 16/100
We simplify this fraction and we have
= 4/25
Therefore,
2.16 = 2 + 0.16
2.16 = 2 + 4/25
2.16 = 
The answer should be the directrix because k represents the y-value of the vertex, and for this questions the parabola is probably facing upward, so the directrix is under the vertex.
