Answer:
So wavelength in decimal can be written as 0.00000155 m
Step-by-step explanation:
We have given wavelength of light used in optic fibers is 
We have to convert this wavelength in decimal form
We know that
can be written as 
So 
So wavelength in decimal can be written as 0.00000155 m
Answer: B. (all numbers less than or equal to -3 will satisfy the inequality)
Step-by-step explanation:
Hi, to answer this question we have to solve the inequality for x:
7 - 5x > 3x + 31
7-31 > 3x +5x
-24 > 8x
-24/8 > x
-3 > x
x < -3
So, the correct option is:
B. (all numbers less than or equal to -3 will satisfy the inequality)
