Answer:
(2) x2+1+4/x+2
Step-by-step explanation:
I hope i am right sorry if i am wrong.
Let's solve your equation step by step
-8=3-5(x+6)
Step 1: simplify both sides of the equation
-8=3-5(x+6)
-8=3+(-5)(x)+(-5(6) (distribute)
-8=3+-5x+-30
-8=(-5x)+(3+-30) (combine like terms)
-8=-5x+-27
-8=-5x-27
Step 2: flip the equation
-5x-27=-8
Step 3: add 27 to both sides
-5x-27+27=-8+27
-5x=19
Step 4: Divide both sides by -5
-5x/-5 = 19/-5
Answer : x= -19/5
Answer:
![E=5.544*10^{-26} J](https://tex.z-dn.net/?f=E%3D5.544%2A10%5E%7B-26%7D%20J)
Step-by-step explanation:
The equation for photon energy is given by:
![E=hf](https://tex.z-dn.net/?f=E%3Dhf)
Where:
![h=Planck\hspace{3}constant=6.6*10^{-34} \\f=Frequency\hspace{3}of\hspace{3}the\hspace{3}wave=84000000Hz](https://tex.z-dn.net/?f=h%3DPlanck%5Chspace%7B3%7Dconstant%3D6.6%2A10%5E%7B-34%7D%20%5C%5Cf%3DFrequency%5Chspace%7B3%7Dof%5Chspace%7B3%7Dthe%5Chspace%7B3%7Dwave%3D84000000Hz)
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](https://tex.z-dn.net/?f=E%3D%286.6%2A10%5E%7B-34%7D%20%29%2A%2884000000%29%3D5.544%2A10%5E%7B-26%7D%20J)
