Nat put $550 in an account which pays four percent interest, compounded semiannually. How much will be in the account in three years?

The final answer will be rounding it up to $619.

Step-by-step explanation:

4% = 0.04

1 represents 100%

therefore,

(( 1 + 0.04)^3)x 550

= (1.04^3) x 550

= 1.124864 x 550

= $618.6752

The final answer will be rounding it up to $619.

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.
