Answer:

Step-by-step explanation:
Arranging the given equation in slope-intercept form ( y = mx + b ):

<em>We know that the perpendicular line would have a slope (m) that is </em><em>negative reciprocal </em><em>of this (
). Thus we can write the perpendicular line's equation as
. </em>
<em />
<em>Now putting x = 4 and y = -6 into the equation, we can solve for b:</em>
<em>
</em>
<em />
Thus, the equation of the perpendicular line is 
Answer:
Volume: 
Ratio: 
Step-by-step explanation:
First of all, we need to find the volume of the hemispherical tank.
The volume of a sphere is given by:

where
r is the radius of the sphere
V is the volume
Here, we have a hemispherical tank: a hemisphere is exactly a sphere cut in a half, so its volume is half that of the sphere:

Now we want to find the ratio between the volume of the hemisphere and its surface area.
The surface area of a sphere is

For a hemisphere, the area of the curved part of the surface is therefore half of this value, so
. Moreover, we have to add the surface of the base, which is
. So the total surface area of the hemispherical tank is

Therefore, the ratio betwen the volume and the surface area of the hemisphere is
