Under MSRB rules, yield to worst means that: A all municipal bonds quoted on a yield basis must be priced to the near-term in whole call date B municipal par bonds quoted on a yield basis must be priced to the near-term in whole call date C municipal discount bonds quoted on a yield basis must be priced to the near-term in whole call date D municipal premium bonds quoted on a yield basis must be priced to the near-term

D. Municipal premium bonds quoted on a yield basis must be priced to the near-term in whole call date

Explanation:

Yield to worst refers to the lowest possible yield which can be gotten on a bond which operates fully within the terms of the contract and doesn't default.

Under MSRB rules, yield to worst means the Municipal premium bonds quoted on a yield basis must be priced to the near-term in whole call date.

Therefore, the correct option is D.

start by isolating the variable on one side by adding 43w^2 to both sides.   the equation will read:

25w^2+5=0

*subtract 5 from both sides*

25w^2=-5

*divide both sides by 25*

w^2=-1/5

*take the square root of both sides*

w=√(-1/5)

the square root of -1 is i.   the square root of 5 remains √5

the answer is i/√5.

hope this
