Answer: 2.077x10^-4
Step-by-step explanation:
Answer:
$6,506.51
Step-by-step explanation:
Recall that increasing an amount C in x% is equivalent to multiply it by (1+x/100)
As we have 4% APR, the monthly interest would be (4/12)% = 0.04/12
<u>Month 0</u> (first payment)
$250
Month 1

<u>Month 2</u>

<u>Month 3</u>

<u>Month 24 (2 years)</u>

The sum

is the sum of the first 24 terms of a geometric sequence with common ratio
which is

so, after 2 years the saving balance is
250*26.02603071 = 6,506.50767= $6,506.51 rounded to the nearest cent.
Answer:
400
Step-by-step explanation:
800-400=400
Answer:

Step-by-step explanation:
The change of distance over time of the plain A is 300 mi/hour and 200 mi/hour for plane B. O is the point of the airport.
So, the distance from A to O AO = 90 miles and BO = 120 miles.
Now, we have a right triangle here. We can use the Pythagorean theorem, so the distance between the planes will be:
(1)


If we take the derivative of the equation (1) we could find the change of the distance between planes.
