Answer:

42300000

Step-by-step explanation:

Use known fact

1\ km=1000\ m

Consider 1 square kilometer:

1\ km^2=1\ km\times 1\ km=1000\ m\times 1000\ m=1000000\ m^2

So, to find the answer, you have to multiply given number of square kilometers by 1000000:

42.3\ km^2=42.3\times 1000000\ m^2=42300000\ m^2

Answer:

1 + ln 2 - ln x

Step-by-step explanation:

ln ( 2e /x)

We know that ln ( a/b) = ln ( a) - ln (b)

ln (2e) - ln (x)

We also know that ln ( a*b) = ln a  + ln b

ln ( 2) + ln e  - ln x

We know that the ln e = 1

ln 2 + 1 - ln x

Changing the order

1 + ln 2 - ln x

The first term of an arithmetic sequence is -5, and the tenth term is 13.
Nitella [24]

Answer:

The common difference is 2

Step-by-step explanation:

The formula for an arithmetic sequence is

an = a1+d(n-1)

a1 = -5

a10 = 13

Substituting n=10 a10=13 and a1 =-5

13 = -5 +d (10-1)

13 = -5 +9d

Add 5 to each side

13+5 = -5+5 +9d

18 = 9d

Divide each side by 9

18/9 = 9d/9

2 =d
