Let the original amount be A. Double that would be 2A.
Then, 2A = Ae^(r*5), or 2 = e^(5r).
Taking the natural log of both sides: ln 2 = 5r. Then r = (ln 2)/5 = 0.14
The interest rate would have to be 13.86% per year, written here as r=0.14.
Answer:
A
Step-by-step explanation:
Answer:
76
Step-by-step explanation:
given a quadratic equation in standard form : ax² + bx + c = 0 : a ≠ 0
then the discriminant is Δ = b² - 4ac
given 3x² - 10x = - 2 ( add 2 to both sides )
3x² - 10x + 2 = 0 ← in standard form
with a = 3, b = - 10 and c = 2
b² - 4ac = (- 10)² - (4 × 3 × 2) = 100 - 24 = 76
Answer:
The another way to write this no. is by adding all the numbers given :
375/18/100
