barxatty [35]

Answer:

$1\frac{1}{4}\ liters$

Step-by-step explanation:

step 1

Convert mixed number to an improper fraction

$1\frac{3}{5}=\frac{1*5+3}{5}=\frac{8}{5}$

step 2

Using proportion

$\frac{2}{(8/5)}\frac{liters}{doors} =\frac{x}{1}\frac{liters}{door}\\ \\x=2/(8/5)\\ \\x=10/8\ liters$

step 3

Convert to mixed number

$\frac{10}{8}\ liters=\frac{8}{8}+\frac{2}{8}=1\frac{1}{4}\ liters$

A sine function increasing through the origin can be used to model light waves. Violet light has a wavelength of 400 nanometers.

andrew11 [14]

Answer:

(2) (100, 300)

Step-by-step explanation:

One wave can be divided on 4 parts, as show on the picture.

Since a length of one whole wave equals 400, a length of each part is $400:4=100$ nanometers.

The height of the wave is decreasing on the second and on the third part, hence over the interval (100, 300).
