Find (8.4 x 1011) (5.25 x 102)(8.0 x 103) , expressed in scientific notation.

the answer that was given before me was wrong I sware to god this is the right answer

Step-by-step explanation:2.0 x 105

1011 - 2 - 3 = 106

and  

8.4

(5.25)(8)

=  

8.4

42

= 0.2

thus,

0.2 x 106 → 2.0 x 105  so this all mean the answer is A

(d)

step-by-step explanation:

given: the line in the graph passes through points (5,30) and (6,26).

then, the equation of line is:

now, put y=a(n) and x=n,

hence, option d is correct.
