PLEASE HELP A hot tub filled with 440 gallons of water is being drained. After 1.5 hours, the amount of water had
decreased to 320 gallons.
The initial amount of water in the hot tub was
440 gallons, so (0, 440) is on the line.
After 1.5 hours, the amount of water had decreased
to 320 gallons, so (1.5, 320) is on the line.

d is the answer

step-by-step explanation:

step-by-step explanation:

i think you should think about the question and not look online.

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)
