Answer:
1/xyz^3
Step-by-step explanation:
exponents are subtracted when divided
x^0 is 1
negative exponents are positive in the denominator
(4x^0y^-2z^-3) / (4xy-1)
(4xy^-2z^-3) / (4xy^-1)
x-1y^-1z^-3
1/xyz^3
Answer:
The answer is 8.5=(x-2.5)^2+(y-3)^2+(z-4.5)^2
Step-by-step explanation:
First we need to find diameter of the sphere. The distance point A and point B is:
![d=\sqrt{(4-1)^2+(3-3)^2+(7-2)^2} \\d=\sqrt{3^2+0^2+5^2} \\d=\sqrt{34} \\d=5.83](https://tex.z-dn.net/?f=d%3D%5Csqrt%7B%284-1%29%5E2%2B%283-3%29%5E2%2B%287-2%29%5E2%7D%20%5C%5Cd%3D%5Csqrt%7B3%5E2%2B0%5E2%2B5%5E2%7D%20%5C%5Cd%3D%5Csqrt%7B34%7D%20%5C%5Cd%3D5.83)
d/2=r=2.92
radius of the sphere is 2.92 units
and the center of the sphere is:
C=((4+1)/2,(3+3)/2,(7+2)/2)
C=(2.5,3,4.5)
We can write the equation of the sphere as:
![r^2=(x-2.5)^2+(y-3)^2+(z-4.5)^2\\8.5=(x-2.5)^2+(y-3)^2+(z-4.5)^2](https://tex.z-dn.net/?f=r%5E2%3D%28x-2.5%29%5E2%2B%28y-3%29%5E2%2B%28z-4.5%29%5E2%5C%5C8.5%3D%28x-2.5%29%5E2%2B%28y-3%29%5E2%2B%28z-4.5%29%5E2)
Answer:
36
Step-by-step explanation:
9+9+9+9=36
Answer:
1/3
Step-by-step explanation:
add all of the totals including the missing pair
we now have 24
7+1 is 8
24 minus 8 is 16
24 can be split into 2 groups of 8
and we have 2/3 left. which makes our solution 1/3
