Answer:
4
Step-by-step explanation:
a + 12/3 = 8
a + 4 = 8
a = 8 - 4
a = 4
taking ln for the both sides
∴
∴ (x+2) ln e = ln (7/5) ⇒ ln e = 1
∴ x + 2 = ln (7/5)
∴ x = ln (7/5) - 2
Using calculator
∴ x ≈ -1.66
Answer:
Rotate a semicircle 180° about its diameter
Step-by-step explanation:
For common figures, the shape of a figure that revolves about a line which is at the base of the figure to give a 3 dimensional shape is the shape of the cross section of the 3 dimensional figure when the angle of revolution is 180° and half the shape of the cross section of the formed 3 dimensional figure, when the angle of revolution is 360°
The cross section of an hemisphere is a semicircle, therefore, the shape of an hemisphere is formed by rotating a semicircle 180° about the diameter (which is the straight line at the "base") of the semicircle
Therefore;
The correct option that gives the revolution that will generate the hemisphere is;
Rotate a semicircle 180° about its diameter.
