4. Murphy started putting $100/month into his 401(k) earning 6% APR when he was 25 years old. How much will be in his account when he retires at age 65, if interest is compounded monthly

The amount in his account is $199,149.07

Explanation:

The computation of the amount in his account is shown below:

= {Compounding period × per month amount × {(1 + rate of interest ÷ Compounding period)^Compounding period × years - 1}} ÷ { rate of interest}

= {12 × $100 × {(1 + 0.06 ÷ 12)^12 × 40 - 1}} ÷ {0.06}

= $199,149.07

Years should be

= 65 - 25

= 40

Hence, the amount in his account is $199,149.07

among other factors, composers started writing dynamic markings in their scores because "new instruments allowed for more dynamic ranges and contrast."

dynamics allude to the loudness or softness of music. dynamics offer an approach to demonstrate articulation in sheet music. they to drive the enthusiastic substance of music through volume and force. maybe you could alter both the volume and the shading profundity on your screen at the same time. we can likewise think about the force side of elements as the quality of a note. a few notes are intended to be played delicately and gently, while others are intended to be played all the more firmly.  

some dynamics markings have a letter 'm,' which remains for mezzo, signifying 'medium.' so a mezzo piano unique stamping resembles this (mp) and intends to play medium calm, while a mezzo specialty dynamic resembles this (mf) and intends to play medium loud.
