The answer would be: D-100. The reasoning of this is because if you take 3 X 10 to the third power and did the exponent (10 to the third power in this case) and multiplied it you would obviously get 1,000 for an answer. Then would would do 1,000 X 3 to get 3,000.
The exponential function shown in the graph is 3^x, so (1/2)3^x is a shrink of it.
Selection B is appropriate.
<span>(2.0x10^4)(3.0x10^3)
= ( 2 x 3)( 10^4 x 10^3)
= 6 x 10^7

The formula for slope is 
In this case:

so...


-1 <<<The slope
Hope this helped!
