Answer:
The correct answer would be C = 533,800
Step-by-step explanation:
The formula for circumference is C = 2πr. To find the radius you must divide the diameter by 2.
Radius = 85000
now we have C = 2 * 85000 * 3.14
C = 533,800
<em>Scientific Formula = 5.338 x 10^6</em>
PART A
The geometric sequence is defined by the equation

To find the first three terms, we put n=1,2,3
When n=1,



When n=2,



When n=3



The first three terms are,

PART B
The common ratio can be found using any two consecutive terms.
The common ratio is given by,



PART C
To find

We substitute n=11 into the equation of the geometric sequence.

This implies that,


Answer:
When adding polynomials you've got to combine all like terms
2u^3 + 7u^3= 9u^3 (They both are raised to the third with the same variable.)
6u^2 (Stays the same because there are no other numbers that are raised to the second)
-7u (Again there are no other numbers to combine this with)
2+4=6 (Add 2+4 as normal)
Now you put together all the numbers that are left for your final answer
9u^3+6u^2-7u+6
Hope this helps ;)
