Choose the situation which would best be modeled by an exponential decay function.

A.
A bank account has fallen below a minimum balance and is being charged $1.50 per day in fees.

B.
A machine depreciates (loses value) by $1000 in its first year, by $2000 in its second, $3000 in its third, etc.

C.
A student’s test score decreases by 5 points for each question missed.

D.
An island is being eroded away and loses 10% of its beachfront every year.

D

Step-by-step explanation:

A is an arithmetic sequence in that is adds or subtracts the same amount.

B is also an arithmetic is that it takes the original 1000 and adds another 1000 for each year

C is a geometric sequence because it's losing 5× however many questions missed

D is the answer because it says it loses 10% every year, so it loses 10% of the previous year, not the beginning year.

answer

point o.

step-by-step explanation:

answer:

the position of equilibrium will shift to the left.

step-by-step explanation:

the general equation for the dissociation of a weak base is

b + h₂o   ⇌   bh⁺ + oh⁻

according to le châtelier's principle, when a stress is applied to a system at equilibrium, the system will respond in a way that tends to relieve the stress.

if you apply a stress by adding more bh⁺ or oh⁻,   the system will respond by moving in a direction that gets rid of the added ions.

the position of equilibrium will shift to the left, forming more of the undissociated base.
