Answer:
3
Step-by-step explanation:
The two quads are of similar, and we know that they are of ratio 1:2, thus
3y+5/7 = 2
y = 3
The wavelength for radio waves with frequency 3 × 10⁹ Hz is 0.1 m.
<h3>What's the relation between frequency and wavelength of electromagnetic waves?</h3>
- For electromagnetic waves travelling in vaccum, the product of frequency and wavelength is the speed of light in vaccum.
- Mathematically, frequency × wavelength = 3×10⁸ m/s (which is speed of light)
- So, wavelength= 3×10⁸/ frequency
<h3>What's the wavelength of radio wave with frequency 3×10⁹ Hz ?</h3>
Wavelength of the radio wave= 3×10⁸/3×10⁹ = 0.1 m
Thus, we can conclude that the wavelength of the radio wave with frequency of 3 × 10⁹ Hz is 0.1 m.

Answer:
To find distance use this equation and plug the variables you have in it.
Equation: Distance=Rate×Time
Hello Alexgator88,
If there are four sections of rope and each piece is 16 inches long then we know that 16 times 4 is 64.
So your answer is 64 inches long.

Answer: f(x)=2-x^2
Step-by-step explanation:
The quadratic equation is
y=ax^2+bx+c
and c is equal to the y-intercept.
in the twi graphs shown both have the same shape but different y-intervepts.
c(the y-intercept) in the first graph is 5 and in the second graph(F) is 2.
