Answer:
400 im pretty sure
Step-by-step explanation:
The -coordinate of the center of mass is the average value of over the plate, given by the ratio of the integral of to the mass of the plate.
The mass of the plate is
while the integral of over the plate is
and the -coordinate of the center of mass is
So your answer according to these hints I provided for you, should lead you to your answer, which should in other words be,
The 1st. The 2nd. And I would say...The 4th. The reason why I say not the 3rd one is because the 4 has nothing to do with the 8, the 3 does because it's divided by it.

Answer:</h2>
Crystal graphed ΔABC using the following points:
On the coordinate plane, consider the point . To rotate this point by 90° around the origin in counterclockwise direction, you can always swap the x- and y-coordinates and then multiply the new x-coordinate by -1. In a mathematical language this is as follows:
<h3>
Therefore, for ΔA′B′C′ we have:</h3>
Since ΔA′B′C′ and ΔT′U′V′ ended up having exactly the same points, then:
On the other hand, in clockwise direction we have the following rule:
<h3>
Therefore. we must find to get ΔTUV here, so:</h3>
