Derek and Susan each open interest-bearing accounts in a bank and put the same amount of money into their accounts. Derek's account earns simple interest. The balance, in dollars, in Derek's account after t years is represented by the function D. Susan's account earns interest at a lesser rate than Derek's account, but the interest is compounded annually. The balance, in dollars, in Susan's account after t years is represented by the function S. Which statement is true? A. At first Susan's account balance will be greater, but eventually Derek's account balance will be greater. B. At first Derek's account balance will be greater, but eventually Susan's account balance will be greater. C. Susan's account balance will always be greater than Derek's account balance. D. Derek's account balance will always be greater than Susan's account balance.

4sqrt5

step-by-step explanation:

the base has dimensions of 8 x 4, so the diagonal is 64 + 16 square rooted or 4sqrt5.

-81 -56 -27 0 81

step-by-step explanation:

statement #3: proof- ang is congruent to ang ecd : angles are congruent.  

step-by-step explanation:

1: the missing angles in statement #3  

a.) acb  

reason- the reason why the answer is acb is because angle ecd and angle acb are both the same size *that's what the word congruent means this is really simple.  

2: the missing word in reason #3  

c.) vertical  

reason- the reason why the answer is vertical is because the angles in that diagram on figure 2 is slanted, which is vertical, and the e and a both lay on vertical lines. along with the other's, but e and a are the 2 main points you want to focus on. and c is kind of like your starting point, because c is for both angles, not just one.  

i hope that was and understanding.
