The differential equation dy dx equals the quotient of the quantity x minus 2 and y minus 2.
Licemer1 [7]

Answer:

The correct option is (b)

Only II applies.

Step-by-step explanation:

Given

dy/dx = (x - 2)/(y - 2)

We want to check which of the given options is true.

I) produces a slope field with horizontal tangents at y = 2

This is not true

II) produces a slope field with vertical tangents at y = 2

This is true because putting y - 2 = 0, we have dy/dx ---> infinity.

Which is a slope field with vertical tangents at y - 2 = 0 or y = 2.

III) produces a slope field with columns of parallel segments

This is not true.

the volume of a cone is 36π cubic units. What is the volume of a cylinder that has the same base area and the same height?
ExtremeBDS [4]
V_cone = 1/3 pi * r^2 * h
V_cylinder = pi*r^2*h

If you multiply the cone's volume by 3 then you get the cylinder's volume. They become the same formula
3 V_cone = pi r^2 h
Since the cone's volume is 36pi They cylinder's volume is 3*36pi = 108 pi

What is the answer to (t+8)(-2)=12
Lunna [17]
(t + 8) (-2) = 12

Distributive property >>>      -2t + -16 = 12

Inverse operation >>>>    -2t + -16+16 = 12+16
 
Simplify >>>>                 -2t = 28

Divide >>>>                       -2t/-2 = 28/-2

Final answer >>>>              t = -14
