Answer:
Step-by-step explanation:
Using the rule of exponents
= 
, hence
f(- 2) = 
= 
=
I think the correct answer is :D
Assuming the wire starts at x=0, the first point is (0,-4) since using y = 3x - 4 :
3(0) - 4 = -4
the two points are (0,4) and (-3,4)
since the y values are the same, the distance is the positive difference between the x values:
-3 - 0 = -3
then,
the distance is 3 meters
each meter costs $125, so multiply the cost by the amount of meters to find the total:
125 x 3 = 375
the total cost is $375
3 x 1015 is 0.5 (0.5024752) times larger than 6 x 1010
hope i could help :)
