60% - 3/5
Hope this help, don't really know what your expecting the answer to be
Y= -1/3x+5
the y-intercept is 5 and the slope is -1/3
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
Answer:
6
Step-by-step explanation:
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
