Answer:
The terms listed are 8, 4, and 2 in that order. From what we can see, it is a geometric sequence whose next term is gotten by dividing the previous term by 2. The formula for finding the nth term of a geometric sequence is given as 
, where
a = first term which is 8
r = common ratio, 1/2 or 0.5
n = is the term we're looking for, 5
Putting all these together into one solid equation, we have
8 * 
=
8 * 
=
8 * 0.0625 = 0.5
Therefore, the 5th term of the sequence is 0.5. Similar example can be seen here brainly.com/question/9300199

First of all, you need to know that profit is the difference between selling price and cost price. In this problem, profit is equal to the markup. Total profit is equal to the profit on each car multiplied by the number of cars sold.
The profit on each car is 2000 -400n, where n is defined in the problem statement as the number of markdowns (of $400).
The number of cars sold is 20 +6n. (Starting at 20, increasing by 6 for every markdown.)
The total monthly profit is the product of these binomials.
.. P(n) = (2000 -400n)*(20 +6n)
.. P(n) = -2400n^2 +4000n +40,000 . . . . . . selection C

Matching functions to data points is often just a matter of trying them to see which fits. The first two function both match points (0, 2) and (1, 6). Functions C and D fail to match (1, 6).
Only the second function matches (2, 18).
The appropriate choice is
.. B. y = 2(3)^x
The speed of plane 1 will be 300 miles/sec and that of plane 2 will be 600 miles/sec.
We have two planes flying in opposite directions to each other.
We have to determine how fast was the each plane flying.
<h3>What is the formula to calculate the distance covered by the object moving with speed - x m/s in time - t s ?</h3>
The formula to calculate the distance travelled will be -
distance = speed x time = (
t) meters
According to the question -
Let us assume that the speed of plane 1 = v miles/sec.
Then, the speed of plane 2 will be = 2v miles/sec.
Distance covered by plane 1 in 3 hours will be = 3v miles.
Distance covered by plane 2 in 3 hours will be = 3 x (2v) miles = 6v miles.
Since they are 2700 miles apart after three hours, therefore -
3v + 6v = 2700
9v = 2700
v = 300 miles/sec
Hence, the speed of plane 1 will be 300 miles/sec and that of plane 2 will be = 2v = 2 x 300 = 600 miles/sec.
