Answer: 69
Step-by-step explanation: The hypotenuse of the atom and it’s vastly large core equals the square root of 420 divides by 5.4 which equals 69.
I can’t understand the question can you write it more clearly?
Complete Question
The complete question is shown on the first uploaded image
Answer:
The line is 
Step-by-step explanation:
From the question we are told that
The line is 
The point is P(0,0 )
Generally the equation for a line is 
Now comparing this with the given equation we see that


Generally the slope of the perpendicular to the given line is mathematically evaluated as

=>
=>
Generally from the univesal equation of a line and the given point we have that
y = mx + c at p(0,0) and
is
0 = -4 (0 ) + c
=> c = 0
Hence the equation perpendicular to the line given at the point given is

200-(-2) is actually 200-1(-2)
So thats multiplication
Then its 200+2
So addition is the last calculation to be done.
