Situation: Find the substance's half-life, in days.
Round your answer to the nearest tenth.
A 10 gram sample of a substance that's
used to detect explosives has a k-value
of 0.1353.
Enter the correct answer.
DONE
-kt
N - Noe
No - initial mass (at time t = 0)
N = mass at timet
k = a positive constant that depends on
the substance itself and on the units
used to measure time
t - time, in days

Which of the following exponentially equations is equivalent to the logarithmic equation below?

Ineed asap. 35 points. in order for two polygons to be similar, two conditions must be met. first, all pairs of corresponding sides must be in proportion. second, all corresponding angles must be congruent. prove that angle congruence is not enough, by itself, to establish that two polygons are similar. do this by describing or drawing two polygons that are not similar but whose corresponding angles are all congruent.
