You could factor a 7 out of 7 + 14 to get 7(1 + 2).
This would equal the same thing as 7 + 14, which is 21.
7 * 3 = 21.
21 can be factored like so:
1 * 21 = 21
3 * 7 = 21
The answer is 340
Explanation:
(g o f)(2) = g(f(2))
f(2) = 6(2)² = 24
g(f(2)) = g(24) = 14(24) + 4 = 336 + 4 = 340
Answer:
The number of years to double the lump sum in value is;
N = 72/10 = 7.20
N = 7.20 years
Step-by-step explanation:
Using the rule of 72 for the approximation:
The formula for rule of 72 is;
Number of years to double = 72/interest rate in percentage
Given;
Interest rate = 10%
The number of years to double the lump sum in value is;
N = 72/10 = 7.20
N = 7.20 years
