Answer:
Step-by-step explanation:
The general equation of a sphere is as follows:
In which the center is 
, and r is the radius.
In this problem, we have that:
So
through the point (4,3,-1)
This leads us to find the radius.
So the equation of the sphere is:
Answer:
The supplement angle 140° angle.
Step-by-step explanation:
Answer:
r=35ft, d=70ft. when r=15 mm, d=30mm
Step-by-step explanation:
Radius is half of diameter
1) X^5Y/X^5= X^0Y= Y (Anything raise to power of 0 is 1)
2)(3mn)^1= 3mn
3)m^-4xM^5= M^-4+5= M
4) 5^-4x5^4= 5^-4+4= 5^0= 1
5) nm^3/n^3m= n^1-3m^3-1= n^-2m^2= m^2/n^2
6) (-2)^0= 1
therefore number 4 and 6 has the value of 1
