similarly, for the xz-plane, find the distance between (3,7,-5) and (3,0,-5)
and for the yz-plane, find the distance between (3,7,-5) and (0,7,-5)
this site looks neat. draw your diagram, fill in the required measurements, enter then in the required fields and follow the solution given.2.a rope is tied 8m apart,and when a wet shirt with mass of 0.8kg is hung at the middle of the line,the midpoint is pulled down 8cm.find the tension is each half of the rope.
plug in the points, you will get:4.if r= (x,y,z), a= (a1,a2,a3) and b= (b1,b2,b3) show the vector equation (r-a).(r-b) = 0 represents a sphere,find its center n radius.
thanks in advance!
take the dot product and simplify to get the form:
the center is (h,k,m) and the radius is R
