Since this is a 3D object, the center of the sphere has 3 coordinates: x=2, y = -6 and z = 4.
The equation would be:
(x-2)^2 + (y+6)^2 + (z-4)^2 = 5^2 (answer).
To find the equation of the intersection of this sphere with the xy plane, let z = 0. Then (x-2)^2 + (y+6)^2 + (0-4)^2 = 25
This simplifies to (x-2)^2 + (y+6)^2 = 5^2 (or 25).
Find and describe the sphere's intersections with the other 2 coord. planes.
Answer:
A. It will be multiplied by 4.
Step-by-step explanation:
When all the dimensions of a 2-dimensional figure are multiplied by a number x then the area is multiplied by x^2. Since all numbers are multiplied by 2 then the area will be multiplied by 2^2 or 4.
To prove this:
12*14=168
Now double the dimensions
24*28=672
Notice that 168*4=672

Answer:
175.5y
Step-by-step explanation:
9 (1.5) = 13.5
13.5 (13) = 175.5
175.5 (1y) = 175.5y
Top one is 56
-9 + <u>112 </u>= 7(x2 - 8x + <u>16 </u>)
