Answer: the third one
Step-by-step explanation:
136 divided by 200 is 0.68 which you then x100 which is 68%
=68%
The others don’t make any sense so it has to be “A”.
Test contains 10 three-point questions and 14 five-point questions.
We have that
(x + 3)² = -20(y − 1)
<span>This is actually the vertex form, so we can obtain the vertex already
</span>the vertex is the point (h,k)------------> (-3,1)
4p=-20------------> p=-5
Focus is at (-3,1-5)---------> (-3,-4)
Directrix is at <span>y = 1-(-5)----------> y=6
</span>
the answer is
the directrix is y=6
