Find the center and radius of the sphere whose equation is given by x2+y2+z2−2x−4y+8z+17=0x2+y2+z2−2x−4y+8z+17=0.
Vedmedyk [2.9K]
We know that
the equation of a sphere is
(x-h)²+(y-k)²+(z-l)²=r²
where (h,k,l) is the center and r is the radius

we have
x²+y²+z²<span>−2x−4y+8z+17=0
</span>

Group terms that contain the same variable, and move the constant to the opposite side of the equation

(x²+2x)+(y²-4y)+(z²+8z)=-17
<span>Complete the square. Remember to balance the equation by adding the same constants to each side
</span>(x²+2x+1)+(y²-4y+4)+(z²+8z+16)=-17+1+4+16
(x²+2x+1)+(y²-4y+4)+(z²+8z+16)=4

Rewrite as perfect squares

(x+1)²+(y-2²)+(z+4)²=4

(x+1)²+(y-2²)+(z+4)²=2²

the center is the point (-1,2,-4) and the radius is 2 units

AB is parallel to CD. AC and BD are perpendicular
Bogdan [553]

Answer:

AB  = CD

Step-by-step explanation:

According to the question, data provided is as follows

AB parallel to CD

AC and BD both are perpendicular to AB and CD

Based on the above information, the relationship between AC and BD is

As we know that

Since AC and BD both are perpendicular to AB and CD and these two are parallel. That means they have the same direction as they are parallel

Moreover, in the case of parallel lines, the perpendicular distance between these two lines would remain the same

Therefore

AB  = CD
