Answer:
$16,532.98
Step-by-step explanation:
Her last deposit = 500, second last = 500 x 1.05, third last = 500 x 1.05^2................ first deposit = 500 x 1.05^19
=500 +500 x 1.05 + 500 x 1.05^2 + 500 x 1.05^19
= 500(1.05^20-1) divided by (1.05-1)
= 16532.98

Answer: ab =6
have:
=> a + b + 1 = ab
⇔ a + b + 1 - ab = 0
⇔ b - 1 - a(b - 1) + 2 = 0
⇔ (b - 1)(1 - a) = -2
because a and b are postive integers => (b - 1) and (1 - a) also are integers
=> (b - 1) ∈ {-1; 1; 2; -2;}
(1 -a) ∈ {-1; 1; 2; -2;}
because (b -1).(1-a) = -2 => we have the table:
b - 1 -1 1 2 -2
1 - a 2 -2 -1 1
a -1 3 2 0
b 0 2 3 -1
a.b 0 6 6 0
because a and b are postive integers
=> (a;b) = (3;2) or (a;b) = (2;3)
=> ab = 6

Answer:
yes, it's a function
Step-by-step explanation:
A function relates one input to one output, and it's "only" one output.
32,000 and 42,000. I know this because the question states "Two Thousands." 32,000 and 42,000 are both two thousands because 32 and 42 both end with 2's because of the "Two" in "Two Thousand."
