Solve this one in exactly the same way as I solved the one
that you posted 1 minute before this one.

--  add up all the ' r 's .

--  add up all of the just-plain-numbers

This time, the answer looks like  9r .

You should spend a few minutes with it so that
you know where this answer comes from.

2. Provide the next three terms in the sequence and
vivado [14]

The next three terms of -243, 81, -27, 9 is -3,1, \frac{-1}{3} 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

-243,-243 \times\left(\frac{-1}{3}\right)^{1},-243 \times\left(\frac{-1}{3}\right)^{2},-243 \times\left(\frac{-1}{3}\right)^{3}

We can say that, above series is in Geometric Progression with first term = -243 and common ratio = \frac{-1}{3}

Then, next three term would be,

-243 \times\left(\frac{-1}{3}\right)^{4},-243 \times\left(\frac{-1}{3}\right)^{5},-243 \times\left(\frac{-1}{3}\right)^{6} \rightarrow-3,1, \frac{-1}{3}

Hence, the next three terms of given G.P series are -3,1, \frac{-1}{3}

Ration in the simplest form<br> 2cm : 1 km
damaskus [11]

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  \frac{2}{100000} =\frac{1}{50000}

Hence, the simplest form ratio is 1  : 50000

Consider the following cost function.
Makovka662 [10]

Answer:

a)Average cost function =\bar{C(x)}=\frac{1000+0.1x}{x}

Marginal cost function =C'x=0.1

b) \bar{C(2000)}=0.6

C'(2000)=0.1

c)\bar{C(2000)}=0.6 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: C(x) = 1000 + 0.1x

a)Find the average cost and marginal cost functions.

Average cost function =\bar{C(x)}=\frac{C(x)}{x}

Average cost function =\bar{C(x)}=\frac{1000+0.1x}{x}

Marginal cost function =C'x=0.1

b) Determine the average and marginal cost when x = a.

a = 2000

Average cost function =\bar{C(x)}=\frac{1000+0.1x}{x}=\frac{1000+0.1a}{a}=\frac{1000+0.1(2000)}{2000}=0.6

So, \bar{C(2000)}=0.6

Marginal cost function =C'(2000)=0.1

c)Interpret the values obtained in part​ (b).

\bar{C(2000)}=0.6 is the average cost to produce first 2000 items

C'(2000)=0.1 is the marginal cost to produce 2001 th item
