Monique and her dad built a hang glider together. After testing the new glider for safety, the glider was ready for the first big flight. Monique jumped off a tall sand dune and traveled in a diagonal line from the top of the dune toward the ground. She flew for 137 feet and landed on level ground at a spot 105 feet horizontally from where she took off. How tall was the sand dune answers are
a. -88 ft
b. 88 ft
c. 173 ft
d. cannot be determined

it would have to be A I think

sorry if this isnt what you're looking for i dont really understand the question

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)
