You have the correct answer. Apply a 180 degree rotation around the point (0,2)
Reason:
We'll connect corners between figures A and B.
Draw a line from the upper right corner of figure A to the lower left corner of figure B. This line is in red (see diagram below).
Draw another line from the lower right corner to the upper left corner. This line is in blue.
The red and blue lines intersect at the center of rotation (0,2)
The line segments constructed consist of endpoints of "before" and "after". For instance, the upper right corner in figure A rotates to the lower left corner of figure B. This happens because of the 180 degree rotation.
Note: You can do this rotation either clockwise or counterclockwise, and you would get the same result.
i believe u r confused about the 5 tanks because 18 can not fit into 5. so here is what it would accurately be.
to find out how many tanks you need your going to need to find the least common multiple. the least common multiple for both are below
18: 1, 2, 3, 6, 9, 18
24:1, 2, 3, 4, 6, 8, 12, 24
the least common multiple is 3. you will need three tanks. now for part b of this equation, to find out how many of each need to be put into the tank. to find this out you need to divide 18 plant and 24 fish by 3 tanks.
18/3 = 6
24/3 = 8
6 plants will go in each tank and 8 fish will go in each tank
the ratio is 6:8 per tank
That is all answers is not link
The ODE appears to be
It's separable; we can write
and integrating both sides yields
