The speed of radio waves can be approximated to be 299,790,000 meters per second. The wavelength of a particular radio station’s
azamat

Answer:

f = \frac{299790000 \frac{m}{s}}{3.03 m}= 9890594.06 Hz

And if we convert to megahertz we got:

9890594.06 Hz *\frac{1MHz}{10^6 Hz}= 98.9 MHz

Step-by-step explanation:

For any mechanical wave we have the following general relationship:

v = \lambda f

where:

v represent the speed of the wave = 299790000 m/s

\lambda = 3.03m represent the wavelength for the radio station

f represent the frequency of interest

If we solve for the frequency we got:

f = \frac{v}{\lambda}

And replacing the values we got:

f = \frac{299790000 \frac{m}{s}}{3.03 m}= 9890594.06 Hz

And if we convert to megahertz we got:

9890594.06 Hz *\frac{1MHz}{10^6 Hz}= 98.9 MHz

M= 1 1/2 going through (6,4) plug into y=mx=+b
Tema [17]
M = 1.5 = 3/2
y = mx + b
b = y - mx = 4 - (3/2)6 = 4 - 9 = -5
So equation of the line is:
y = 3x/2 - 5
