Which of the following did you include in your response?
A) This is a quadratic function, which is usually
defined on all reals. But, the domain is restricted to x>_0 because it does not make sense to produce a negative number of units.
B) Find the vertex of the parabola at
(10.14, 164.5).
C) Since the parabola opens up, the range is
y>_ 164.5.

all but the second one

step-by-step explanation:

cuz that one goes over 180

mark brainliest

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)

care to share were the trapezoid shown is ?
