Answer:
Kindly check explanation
Step-by-step explanation:
Given that :
Motorcycle driver travels 15kph faster than a bicycle rider
Motorcycle covers 60km in 2 hours less than the time it takes bicycle rider to travel the same distance ;
Let bicycle rider's speed = r kph
Motorcycle driver's speed = (15 + r) kph
TIME it takes bicycle rider to cover a distance of 60km = t hours
TIME it takes motorcycle driver to cover a distance of 60km = (t - 2) hours
Answer:
Hence, the sphere has a radius of 
and is centered at the point (1,-1,1)
Step-by-step explanation:
We have the equation
We have to take into account the relation between coordinates
by substituting we have:
![\rho=2[\frac{x}{\rho}-\frac{y}{\rho}+\frac{z}{\rho}]\\\\\rho^2=2x-2y+2z\\\\x^2+y^2+z^2=2x-2y+2z](https://tex.z-dn.net/?f=%5Crho%3D2%5B%5Cfrac%7Bx%7D%7B%5Crho%7D-%5Cfrac%7By%7D%7B%5Crho%7D%2B%5Cfrac%7Bz%7D%7B%5Crho%7D%5D%5C%5C%5C%5C%5Crho%5E2%3D2x-2y%2B2z%5C%5C%5C%5Cx%5E2%2By%5E2%2Bz%5E2%3D2x-2y%2B2z)
We have to complete squares:
Hence, the sphere has a radius of and is centered at the point (1,-1,1)
hope this helps!!
