Answer:
"To the nearest year, it would be about 9 years"
Step-by-step explanation:
11c)
This is compound growth problem. It goes by the formula:
Where
F is the future amount
P is the present (initial) amount
r is the rate of growth, in decimal
t is the time in years
Given,
P = 20,000
r = 8% = 8/100 = 0.08
F = double of initial amount = 2 * 20,000 = 40,000
We need to find t:
To solve exponentials, we can take Natural Log (Ln) of both sides:
Using the rule shown below we can simplify and solve:
We can write:
To the nearest year, that would be about 9 years
it is true because 14 is 1/14
Answer:
-44/5 = a
Step-by-step explanation:
- 26 = 8 + 5(a + 2)
Subtract 8 from each side
- 26-8 = 8-8 + 5(a + 2)
-34 = 5(a +2)
Distribute
-34 = 5a +10
Subtract 10 from each side
-34-10 = 5a +10-10
-44 = 5a
Doivide each side by 5
-44/5 = 5a/5
-44/5 = a
