Ireally need with this, very long question. every morning 20 grams of ointment has to be applied to a 65cm thigh & 40 cm calf. every 6 hours 20% of the 20 grams have to be reapplied. how many grams of ointment must be applied every 6 hours. and how long will a 120 gram tube of ointment last if the ointment is applied for 12 hours a day every day.

4 grams every 6 he's a total of 28 grams per day the tub will last 4.2 days

Step-by-step explanation:

the correct answer is b. negative exponential growth.

step-by-step explanation:

you can tell it's an exponential function because it decreases rapidly then levels out and never touches the x-axis.

it is negative because the y-axis decreases as the x-axis increases.

therefore it is a negative exponential growth graph.

hope i !
