Okay so you take the 12 feet I'm pretty sure you multiply 12 and 30 and then that's one of your answers and then the 12 and a 75 you must put those to together and that's an answer and you subtract your 12 x 30 and you're 12 x 75 and that's how you get your answer I am pretty sure that's how you and that's how you get your answer I am pretty sure that's how you do it
Answer:
The exact interest on $5,870 at 12% is $410.9
Step-by-step explanation:
From the information provided we know that
Principal amount: $5,870
Interest rate: 12% -> 0.12
Time: 7 months (From June to December)
When you know the principal amount, the rate, and the time, the amount of interest can be calculated by using the formula:

where P is principal, r is the rate of interest and t is the time in years.
We need to convert the 7 months into 1 year.

Now we can use the above formula

Therefore the exact interest on $5,870 at 12% is $410.9
Same slope, different y-intercept
Answer:
The series converges to
for
Step-by-step explanation:
Given the series is 
We have to find the values of x for which the series converges.
We know,
converges to (a) / (1-r) if r < 1
Otherwise the series will diverge.
Here,
is a geometric series with |r| = | 9x |
And it converges for |9x| < 1
Hence, the given series gets converge for 
And geometric series converges to 
Here, a = 1 and r = 9x
Therefore, 
Hence, the given series converges to
for
