Answer: I think its 4
Step-by-step explanation:
178 - (-395)
178 + 395 = 573
the distance between -395 and 178 is 573
hope this helps
ANSWER

EXPLANATION
Since the parabola has the (0, 0) and the directrix at y=2.
The equation is of the form

where (h,k) is the vertex.
The vertex is half way between the directrix and the focus.
The vertex will be at (0,1)
and is the distance from the vertex to the focus which is 1.


Answer:
4). 
Step-by-step explanation:
The Given expression is that,
On simplifying,

is the correct simplification of the given expression.
Answer:
B
Step-by-step explanation:
Euler's formula for polyhedra states that
F + V - E = 2
where F is faces, V is vertices and E is edges
Substitute the values given and solve for F, that is
F + 13 - 26 = 2
F - 13 = 2 ( add 13 to both sides )
F = 15 → B
