Answer:
There is one point: A (x, y) = (2, 0)
Step-by-step explanation:
A point of the square OABC is invariant only if its location coincides with location of the rotation axis, that is, that such point experiments only rotation, no translation in any form. The center of rotation coincides with the location of one of the vertices of the square and, therefore, there is one invariant point on the perimeter: A (x, y) = (2, 0)
Answer:
No
Step-by-step explanation:
2x-3y= 6xy
2π = <span>2π * r / 5 => 1 = r / 5 => r = 5.</span>
The only selection that has the coordinates of point A multiplied by 4.5 is
Selection A (-18, 27).
It's easy to show that 
is strictly increasing on ![x\in\left[0,\frac\pi8\right]](https://tex.z-dn.net/?f=x%5Cin%5Cleft%5B0%2C%5Cfrac%5Cpi8%5Cright%5D)
. This means
and
Then the integral is bounded by
