Find the equation of the sphere of radius 5 that lies above the xy-plane that just touches the xy-plane at the point (4, −6, 0)

touches the xy-plane at the point (4, −6, 0)

70

step-by-step explanation:

2*5=10

4*15=60

60+10=

70

step-by-step explanation:

given that ab is divided into equal parts as

ac, cd, de, ef, fg, gh, hi, ib.

from this we find that f is the midpoint of ab.

so using mid point formula we find

f = (3,7)

similarly considering fb, we get

h = mid point of fb = ((6,6) and g, mid point of fh is

g = (9/2, 13/2)

i is mid point of hb

so i =(15/2,11/2)
