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
nanometers.
The height of the wave is decreasing on the second and on the third part, hence over the interval (100, 300).
Rectangle on the top: 3a^4b^2
Second: 35x^6y^8z^2
Square: 108x^8y^2
Well 4/5 is 80% and 9/10 is 90%
9/10 is bigger. :)
Answer:
19
Step-by-step explanation:
200−181 = 19
There are 19 whole numbers between 181 and 200.
