Choices A, C and F work. This is because when in radical form, you may dive or subtract as long as you keep the sign. The square root of 9 is 3 and the square root of 4 is 2. When you solve it, the answer is 6. Hope this helped!
Answer:
![f = \frac{299790000 \frac{m}{s}}{3.03 m}= 9890594.06 Hz](https://tex.z-dn.net/?f=%20f%20%3D%20%5Cfrac%7B299790000%20%5Cfrac%7Bm%7D%7Bs%7D%7D%7B3.03%20m%7D%3D%209890594.06%20Hz)
And if we convert to megahertz we got:
![9890594.06 Hz *\frac{1MHz}{10^6 Hz}= 98.9 MHz](https://tex.z-dn.net/?f=9890594.06%20Hz%20%2A%5Cfrac%7B1MHz%7D%7B10%5E6%20Hz%7D%3D%2098.9%20MHz)
Step-by-step explanation:
For any mechanical wave we have the following general relationship:
![v = \lambda f](https://tex.z-dn.net/?f=%20v%20%3D%20%5Clambda%20f)
where:
v represent the speed of the wave = 299790000 m/s
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}](https://tex.z-dn.net/?f=%20f%20%3D%20%5Cfrac%7Bv%7D%7B%5Clambda%7D)
And replacing the values we got:
![f = \frac{299790000 \frac{m}{s}}{3.03 m}= 9890594.06 Hz](https://tex.z-dn.net/?f=%20f%20%3D%20%5Cfrac%7B299790000%20%5Cfrac%7Bm%7D%7Bs%7D%7D%7B3.03%20m%7D%3D%209890594.06%20Hz)
And if we convert to megahertz we got:
![9890594.06 Hz *\frac{1MHz}{10^6 Hz}= 98.9 MHz](https://tex.z-dn.net/?f=9890594.06%20Hz%20%2A%5Cfrac%7B1MHz%7D%7B10%5E6%20Hz%7D%3D%2098.9%20MHz)
Answer:
it would be Y= -2x+4
Step-by-step explanation:
To begin, we know that the b value is 4, because that is the x-intercept that is information given, so we can atomatically put that in.
Next we need to find the m value, which can be found by knowing the rules of a perpendicular eqution. to change it you must change the 1/2 and flip the equation and change the signs
soooooo 1/2 would change into 2/1 which is 2 and we would addd the negative sign so
Y=-2x+4
