When rotating a point 180 degrees about the origin, you are simply inverting the points.
(5, -2) rotated 180 degrees results in (-5, 2).
V = 1/3 area of base * height
Area of base = h [(b₁ +b₂)]/2
[(3 + 6) * 4] : 2 =
18 ft²
Volume =
18 * 3 =
54 ft³
Given:
6 . ln x = 9.1
We are asked to find the solution of the above equation leaving the answer to two decimal places.
6lnx = 9.1
Let's divide both sides by 6
6linx/6 = 9.1/6
6 cancelling out on the left hand side.
lnx = 9.1/6
linx = 1.5166
x = e^1.5166
x = 4.5570
x = 4.56 (to two decimal places).
The correct option is A, which is x = 4.56
