At the time of her​ grandson's birth, a grandmother deposits $3000 in an account that pays 9.5% compounded monthly. What will be the value of the account at the​ child's twenty-first​ birthday, assuming that no other deposits or withdrawals are made during this​ period?

the answer is

256731576000000

74820

Step-by-step explanation:

9.5% of 3000 is 285

there are 12 months in a year

so 12 times 21 equals 252

so 285 times 252 add 3000 equals 74820

3 1/3 x 2 3/5 = 8 2/3

step-by-step explanation:

just multiply the first number by the second number to get your answer.

answer:   x = 3 + √11     and     x = 3 - √11

step-by-step explanation:

x² - 6x + 9 = 11

(x - 3)² = 11

x - 3 = ±√11

    x = 3 ± √11

x = 3 + √11     and     x = 3 - √11
