Answer:
Critical points of an equation are the zeroes of its first derivative. Since you have already provided me with the derivative (thanks for saving me the effort :) ), I am just going to start the process.
tan (x) + x(sec^2(x)) = 0
Solving this equation (using a graphing calculator set to radians), it is only true when x = 0.
So, 0 is a critical point of this function.
Hope this helped!
Answer:
So let's think about it
Time start: 2:45
complete the hour you get 3:00
and add an hour you get 4:00
So the hour is 4:00
The height of the pyramid is 14.4 cm.
<h3>How to find the height of the pyramid?</h3>
volume of a pyramid = 1 / 3 Bh
where
- B = base area
- h = height of the pyramid
Therefore,
volume of the cube = L³
where
- L = side length of the cube
Hence,
volume of the cube = 10³
volume of the cube = 1000 cm³
The volume of the pyramid is the same with the volume of the cube.
Hence,
1000 = 1 / 3 Bh
The height of the pyramid is the same as the square base.
Therefore,
1000 = 1 / 3 (h²)h
1000 = 1 / 3 h³
cross multiply
3000 = h³
h = ∛3000
h = 14.4224957031
Hence, the height of the pyramid is 14.4 cm.

Step-by-step explanation:
Translation right 6 units adds 6 to every x-coordinate. Rotation 90° CW is the transformation (x, y) ⇒ (y, -x). The sequence of transformations gives ...
(x, y) ⇒ (y, -x-6)
Then the coordinates of the transformed figure are ...
P(-3, 7) ⇒ P'(7, -3)
Q(4, 12) ⇒ Q'(12, -10)
R(4, -2) ⇒ R'(-2, -10)
S(-3, -7) ⇒ S'(-7, -3)
