Which is the equation of Line B?
notka56 [123]
  • Slope-Intercept Form: y = mx + b, with m = slope and b = y-intercept
  • Slope Formula: \frac{y_2-y_1}{x_2-x_1}

So firstly, to find the slope of this equation, plug the two points, (1,1) and (-3,2), into the slope formula and solve as such:

\frac{1-2}{1-(-3)}=-\frac{1}{4}

Next, plug either one of the points into the x and y coordinates to solve for b as such:

2=-\frac{1}{4}*-3+b\\2=\frac{3}{4}+b\\\frac{5}{4}=b

<u>Our final equation is y=-\frac{1}{4}x+\frac{5}{4} , or the third option.</u>

An FM radio station broadcasts at 84 megahertz (MHz). What is the energy of each photon in Joule? Use h = 6.6 * 10 ^ (- 34) * j
iragen [17]

Answer:

E=5.544*10^{-26} J

Step-by-step explanation:

The equation for photon energy is given by:

E=hf

Where:

h=Planck\hspace{3}constant=6.6*10^{-34} \\f=Frequency\hspace{3}of\hspace{3}the\hspace{3}wave=84000000Hz

This equation telling us that the higher the frequency of the photon, the greater its energy. And the longer the photon wavelength, the lower its energy.

So, replacing the data provided in the previous equation:

E=(6.6*10^{-34} )*(84000000)=5.544*10^{-26} J
