Answer:
x = 6
Step-by-step explanation:
The two angles are vertical angles and vertical angles are equal
5x = 3x+12
Subtract 3x from each side
5x -3x = 3x+12-3x
2x= 12
Divide by 2
2x/2 = 12/2
x = 6
The vertex moves 7 to the right and the parabola becomes thinner unless adjusted
An hemispherical dome is half a sphere. If the diameter is 60 m, then the radius is 30 m.
We can use differentials to solve this problem because we are adding a thin layer to the original dome, so the volume of the dome in increased by a differential of itself.
This differential volume that the dome is increased is equal to the volume of the coat of paint.
The volume of the dome can be written as:

Now, we can calculate dV as:

Answer: the paint needed for this coat is approximately 7.92 m^3
