Answer:
Step-by-step explanation:
Given that a sphere has one of its diameters has endpoints (9, 7, 5) and (10, 9, 8) which has been normalized so that the coefficient of x2 is 1.
We know centre of a sphere is the mid point of diameter.
Hence centre of sphere =
Diameter length = distance between the given points
=
Radius of sphere = half of diameter =
Using radius and centre we can write equation of sphere as
Answer:
18
Step-by-step explanation:
Because angle A and C are equal, it is an isoceles traingle.
This means that side BA is equal to side BC.
Thus, you can set 6x equal to 3x + 9.
Solving that gives you x = 3.
6(3) = 18 3(3) +9 = 18
