Answer:
1000
Step-by-step explanation:
1 is the nearest in 1.2
Answer:
2.5
Step-by-step explanation:
a = 1
b = 5
ab
= 1 x 5
= 5
0.5b
= 0.5 x 5
= 2.5
ab - 0.5b
= 5 - 2.5
= 2.5
Answer:
See Below
Step-by-step explanation:
The question is asking:
After how many years, 20,000 will become 500,000 at an annual interest of 11.5%?
So, we need compound growth formula shown below to solve this:

F is future value
P is present amount
r is rate of interest
t is the time of year
Given,
F = 500,000
P = 20,000
r = 11.5% = 11.5/100 = 0.115
t is what we want to find

Now, we take natural log of both sides and solve for t:

Its is going to take about 29.57 years, rounding, 30 years
Answer:
The "Verticle" line test is used to determine if a graph represents a function.
Step-by-step explanation:
This is due because functions have to contain one output and not multiple, and this can be tested with the vertical line test. Hope this helps!
I use simple annual interest to solve the problem
<span>$125.37 -------------------------------- 3 years
X-------------------------------------------> 1 year
X=125.37/3=</span>$41.79/ year
<span>$597--------------------->100%
</span>$41.79---------------------X%
X=41.79*100/597=7%
The rate was 7%
