Situation:

a 39 gram sample of a substance that's a by-product of fireworks has a k-value of 0.1024.

n = n0e -kt

n0 = initial mass (at time t = 0)

n = mass at time t

k = a positive constant that depends on the substance itself and on the units used to measure time

t = time, in days
find the substance's half-life, in days.

round your answer to the nearest tenth.

Three coins are flipped. what is the probability that there will be at least two tails?

In the figure below, segment ac is congruent to segment ab: triangle abc with a segment joining vertex a to point d on side bc. side ab is congruent to side ac which statement is used to prove that angle abd is congruent to angle acd? segment ad bisects angle cab. triangle acd is similar to triangle abd. segment ad is congruent to segment ac. angle cab is congruent to angle cba.
