Answer:
John Muir
John Muir was an American naturalist born in Scotland on April 21, 1838. Step-by-step explanation:
I think it’s between the first and third one
The surface area 3 times greater than the area.
6 * 2 gives the area
the surface area is by multiplying area by 3.
this means that the surface area is 3x bigger than area.
This is a parabola which opens upwards and the directrix will be of the form
y = k
the general form is
4p(y - k) = (x - h)^2 we have:-
1/4(y + 3) = (x - 2)^2
so the vertex is at (2, -3)
4p = 1/4 so p = 1/16
so the focus will be at (2 , -2 15/16)
and directrix is y = -3 1/16
