Assume that the variables x and y are directly related. If k= 8, what is the value for each of the following points? Be sure and record your data to be used in the following problem.
х у
k
16
0.5
80
00
1
80
4
00
2
2.66
3
8

the answer would be a

in scientific notation, the value of the  speed of light in a vacuum

  will be written as 2.995 * 10^8. when this value is represented in the form of

  a * 10^b, then, a = 2.995 and b = 8.

the value of the speed of light in a vacuum given above can also be rounded up to approximately 300000000. in this case, the scientific notation will be written as 3 *10^8.

the right answer is c i just did the question.
