It's not entirely clear what the full problem is as it is cut off; however, it looks like you're using the speed of light (c) which is 3.00*10^8 meters per second. So you would use that instead of 3.00*10^(-9).
Doing so yields the following
c/lambda = (3.00*10^8)/(1.26*10^(-7)) = (3.00/1.26)*10^(8-(-7)) = 2.38*10^15
which fits with the result you have on the right side
Answer: C≈628.32
Step-by-step explanation: This is due to the fact that the formula to find the circumference would be C=2πr which in this case the raduis would be 100 because if u divide the diameter by 2 u get 100. Now the formula is 2*3.14*100
Answer:
Step-by-step explanation:
The general form of the line is 
. So, the value of the slope must be 12. In this case:
Answer: 9 R53
