Pl help me. Write the equation of the parabola given the following information:

Directrix: x=6

Focus (2,0)

32-8x=y^2 or x=4-y^2/8

Step-by-step explanation:

B

Step-by-step explanation:

Rc =6.7×10^-11 and Rs=1.9×10^-10

since power of 10 is negative in both hence greater the magnitude of power lesser is its value

hence Rc is less than Rs

ratio of radius of atom of sodium to radius of carbon = (1.9×10^-10)÷(6.7×10^-11)

                                                                                        =2.84

hence B
