Compound interest worksheet

Assume a business man banks an amount of principle P, for n years at a compound interest of r%. His accumulated amount after n years will be given by formula:

Note that compound interest borrows a hint from the geometric progression series.

Accumulated = 5000(1 + 10%)^5

Accumulated = 5000(1 + 0.1)^5

Accumulated = 5000 × 1.61

Accumulated = 8052.55 /=

2 x^2 -3x+p

sum of roots = 3/2

let other root be x

3+ x = 3/2

x= 3/2 - 3 = -3/2

product of roots = p/2

3× -3/2 = p/2

-9 = p

⭐⭐

0.16 or 16%

step-by-step explanation:

lets take a coin for example.

if you toss it twice, it has a 1/4 chance of landing on heads both times because 1/2 * 1/2 is 1/4.

with the cards, the chance of picking dog is 0.4. having two people pick one is like picking a card twice in a row. so 0.4 * 0.4 is 0.16, or 16%
