Count the number of digits after the first digit. this gives you the exponent on the 10. The first number in scientific form has the decimal point after the first digit.

For mercury there are 7 digits after the 5:-

So the Mercury answer is

5.7909175 * 10^7

Follow this procedure for the other planets

The answer for Venus is

Write the first five terms of the sequence defined by the recursive formula

stepan [7]

<u>Answer:</u>

The correct answer option is: $S_9=\frac{9}{2} (2+26)$

<u>Step-by-step explanation:</u>

We know that,

the sum of the first $n$ terms of an Arithmetic Sequence is given by:

$S_9=\frac{n(a_1+a_n)}{2}$

where $n$ is the number of terms,

$a_1$ is the first term of the sequence; and

$a_n$ is the first term of the sequence.

So for $a_n=3n-1$ ,

$a_1=3(1)-1=2$

and

$a_9=3(9)-1=26$

Putting these values in the formula to get:

$S_9=\frac{9(a_1+a_9)}{2}$

$S_9=\frac{9(2+26)}{2} \\\\S_9=\frac{9}{2} (2+26)$

<u>First five terms:</u>

$a_1=3(1)-1=2$

$S_1=\frac{1(2+2)}{2}$ =2

$a_2=3(2)-1=5$

$S_2=\frac{2(2+5)}{2}$ =7

$a_3=3(3)-1=8$

$S_2=\frac{3(2+8)}{2}$ =15

$a_4=3(4)-1=11$

$S_4=\frac{4(2+11)}{2}$ =26

$a_5=3(5)-1=14$

$S_5=\frac{5(2+14)}{2}$ =40
