Answer:
3, 9
Step-by-step explanation:
The only factors of 27 are 1, 3, 9, and 27, so we can look at the numbers and see which ones have a difference of 6. 3 and 9 have a difference of 6, so the numbers are 3 and 9. I hope I helped!
Answer:
Step-by-step explanation:
(0, 4) (2, 0)
(0-4)/(2-0) = -4/2 = -2
y - 4 = -2(x - 0)
y - 4 = -2x + 0
y = -2x + 4
Answer:
56.39 nm
Step-by-step explanation:
In order to have constructive interference total optical path difference should be an integral number of wavelengths (crest and crest should be interfered). Therefore the constructive interference condition for soap film can be written as,

where λ is the wavelength of light and n is the refractive index of soap film, t is the thickness of the film, and m=0,1,2 ...
Please note that here we include an additional 1/2λ phase shift due to reflection from air-soap interface, because refractive index of latter is higher.
In order to have its longest constructive reflection at the red end (700 nm)

Here we take m=0.
Similarly for the constructive reflection at the blue end (400 nm)

Hence the thickness difference should be

Answer:
Step-by-step explanation:
he average walking speed of a human is 3 to 4 miles per hour, or 1 mile every 15 to 20 minutes. How fast you walk can be used as an indicator of overall health. Several variables contribute to individual differences, including age, sex, and height.

2(x - 4) + 7(x + 4)
(2x - 2 • 4) + (7x + 7 • 4)
