The next three terms of -243, 81, -27, 9 is
The given series is geometric series
<u>Solution:</u>
Given, series is -243, 81, -27, 9, …
We have to find the next three terms of the above given series.
Now, the given series can also be written as

We can say that, above series is in Geometric Progression with first term = -243 and common ratio = 
Then, next three term would be,

Hence, the next three terms of given G.P series are
D - 6.3
Plug in 4.26 for 'd':
4.26 - 6.3 = -2.04
Answer:
The simplest form ratio is 1 : 50000.
Step-by-step explanation:
To find the ratio of 2 cm : 1 km
Firstly, we need to convert both the quantities into the same unit of measurement.
Now 1 km = 1,00,000 cm
So, now we need to find the ratio of 2 cm : 1,00,000 cm
⇒ The required Ratio is 
Hence, the simplest form ratio is 1 : 50000
Answer:
a)Average cost function =
Marginal cost function =
b) 

c)
is the average cost to produce first 2000 items
C'(2000)=0.1 is the marginal cost to produce 2001 th item
Step-by-step explanation:
Cost function: 
a)Find the average cost and marginal cost functions.
Average cost function =
Average cost function =
Marginal cost function =
b) Determine the average and marginal cost when x = a.
a = 2000
Average cost function =
So, 
Marginal cost function =
c)Interpret the values obtained in part (b).
is the average cost to produce first 2000 items
C'(2000)=0.1 is the marginal cost to produce 2001 th item
