Let the another number is x
And the sum of number is 30
And the one number is 23
x+23=30
x=30-23
x=7
the another number is 7
Answer:
Indus River
Step-by-step explanation:
Answer:
The wave's wavelength λ = 5 m
Step-by-step explanation:
<u><em>Explanation:-</em></u>
Given that the frequency f = 30HZ
Given that the velocity
'v ' = 150m/s
The wave's wavelength
The wave's wavelength λ = 5 m
What are the answer choices?
Because the function f(x) =-2+√x+7 has √x, x should be more or equal 0.
Domain is x≥0, or [0,+∞).
The smallest value of x=0, so the smallest value of f(x) is f(0) =-2+√0+7=5,
so range is f(x)≥5, or [5, +∞).
