Suppose you deposit $2000 in a bank account that has a doubling time of 19 years. to the nearest $100, what will your balance be after 5 years? a. $2400 b. $2500 c. $7600 d. $27,900

The expression for the balance (b) in terms of the number of years (t) can be written as

... b = 2000·2^(t/19) . . . . . . the amount grows exponentially, and is is doubled when t=19

Then for t=5, the balance is

... b = 2000·2^(5/19) ≈ 2400

The best choice is ...

... A. $2400

i think it is everything has to equal 180 so, if i correct 4=c. 6=d. 8=a. 7=b. and the last question would be c. because they are parallel lines and they are congruent.

step-by-step explanation:

the reason everything has to equal to 180 is because that is how it works. i'm guessing that is its rule. 4 and 8 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 6 and 7 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 60+60 is 180. so, now you have your answer
