Answer:
sphere (see the explanation)
Step-by-step explanation:
we know that
When you will rotate a circle about its diameter, you will obtain a sphere.
The radius of the sphere will the same as that of the circle.
In this problem
The circle is rotated about the line y=1
The line y=1 passes through a diameter of the circle
The equation of the circle is
![(x-1)^2+(y-1)^2=1](https://tex.z-dn.net/?f=%28x-1%29%5E2%2B%28y-1%29%5E2%3D1)
see the attached figure to better understand the problem
so
The circle is rotated about its diameter
therefore
The resulting three-dimensional object will be a sphere with radius of 1
Answer:
M=-9/8
Step-by-step explanation:
-3/8-3/4=-3/8-6/8=-9/8
Answer: M =
Step-by-step explanation:
![\frac{M(x+y)+4y}{x^{2}-xy-y^{2} } =\frac{(x+2y)}{x^{2} -xy-y^{2} }](https://tex.z-dn.net/?f=%5Cfrac%7BM%28x%2By%29%2B4y%7D%7Bx%5E%7B2%7D-xy-y%5E%7B2%7D%20%20%7D%20%3D%5Cfrac%7B%28x%2B2y%29%7D%7Bx%5E%7B2%7D%20-xy-y%5E%7B2%7D%20%7D)
M (x + y) + 4y = x + 2y (Multiply
in both sides)
M (x + y) = x + 2y - 4y
M (x + y) = x - 2y (Divide (x+y) from both sides)
M =
M = (-5/4)n - 2
To solve for m, you need to isolate m on one side by performing the same function to both sides. So starting with:
-5n = 4m + 8
Subtract 8 from both sides
-5n - 8 = 4m
Divide both sides by 4
(-5/4)n - 2 = m
Swap sides
m = (-5/4)n - 2
