x + y = 24 where x and y are the 2 parts of diagonal Other diagonal wil be smaller that 24.
x^2 + z^2 = 13^2
y^2 + z^2 = 20^2 where z = 0.5 * length of smaller diagonal)
form last 2 equations
y^2 - x^2 = 20^2 - 13^2 = 231
now y = 24-x so we have
(24 - x)^2 - x^2 = 231
576 - 48x = 231
48x = 345
x = 7.1875
z^2 = 13^2 - 7.1875^2 = 117.34
z = 1.83
so smaller diagonal = 21.66 cm
looks like its the third choice.
The answer to this question would be
5= rotating 90° clockwise
6= mirrored diagonally (\)
In this case, the picture in number 5 is moved 1 quadrant to the clockwise direction. In this problem, it is either the picture rotated 90° clockwise or mirrored to the Y lines. If it mirrored, the effect would be X point become minus. But seeing the point B and C, the effect is
1. X and Y switched
2. X become minus
This effect is gained when you rotating 90° clockwise
In number 6, the picture moved 2 quadrants. It will be either rotated 180° or mirrored diagonally. The effect on the image is:
1. X and Y switched
2. Both X and Y become minus
This effect is gained if the shape was mirrored.
It is use anytime pretty much
The answer is (B).
If we substitute r = 6 inches into the volume of a sphere formula we get this:
π6³
Since 6³ = 216, we multiply this by 1.3333 to get 288. If we multiply this by pi we get 288π, or (B).
