By the time her grandson turns 21, the account will be worth $ 8,554.27.

Step-by-step explanation:

Given that at the time of her grandson's birth, a grandmother deposits $ 3000 in an account that pays 5% compounded monthly, to determine 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 following calculation must be performed:

X = 3,000 (1 + 0.05 / 12) ^ 21x12

X = 8,554.27

Thus, by the time her grandson turns 21, the account will be worth $ 8,554.27.

hello from mrbilldoesmath!

answer:   x^2 + y^2 = 1024

discussion:

the equation of a circle with center (h,k) and radius "r" is

(x-h)^2 + (y-k)^2 = r^2.

in our case

(x-0)^2 + (y-0) ^2 = 32^2 = 1024

you,
