Name the type of symmetry for the figure.
reflectional
rotational
rotational and reflectional
no symmetry
does anyone have the whole

Rotational

Step-by-step explanation:

Reflectional symmetry is when a figure can be folded in half through some given line and half each half congruent to the other.  There is no line through which to fold this figure, so there is no reflectional symmetry.

Rotational symmetry is when a figure can be turned some degree and be congruent to itself; This figure can be rotated 180°, so this has rotational symmetry.

1,645,493,059.35

step-by-step explanation:

step-by-step explanation:

the original amount doesn't ''re just looking for the time it takes for 1/2 of the substance to we have

(1/2) =)     take the ln   of both sides

ln (1/2)   = )   and we can write

ln(1/2) = ) lne     and lne   = 1     so we have

ln(1/2) = -.1092t     divide both sides by -.1092

t = ln(1/2)/-.1092 = about 6.347 days = about 6.3 days (rounded)
