Initially I have $10000 sitting in a bank paying 7% effective annual rate, I scheduled a level withdrawal annually starting now so that after 10 withdrawals the balance is zero. This withdrawal amount is deposited into an
investment account paying a whopping 20% annual rate. Interest earned
from this account is deposited back into the bank account annually. I forgot
to stop the scheduled withdrawal, will I have enough money to deposit into
the investment account at year 10?

option (b) is correct

step-by-step explanation:

to find the solution of this system, we need to convert it into reduced row-echelon form. we have,

after applying row operations r2 -> r2/2 and r3 -> r3/3, we get,

c. 27 units.

step-by-step explanation:

we are told that in circle a, ∠bae ≅ ∠dae.

we can see from our given diagram that in and ;

, as these are radii of our given circle.

therefore, by sas congruence postulate.

hence, side be will be equal to side de as corresponding parts of congruent triangles are congruent. so we can set an equation to find the value of x as:

now let us substitute x=17 in the expression for the length of be.

therefore, length of be will be 27 units and option c is the correct choice.
