<u>Answer:</u>
<u>
</u>
<u>Step-by-step explanation:</u>
From the graph, we can see that y = -1 when x = 0.
So to check whether which of the given options is the equation of the given graph, we will set our calculator to the radian mode and then plug the value of x as 0.
1. y = cos(x + pi/2) = cos(0 + pi/2) = 0
2. y = cos(x+2pi) = cos(0+2pi) = 1
3. y = cos(x+pi/3) = cos(0+pi/3) = 1/2 = 0.5
4. y = cos(x+pi) = cos(0+pi) = -1
Therefore, the equation of this graph is y = cos(x+pi) = cos(0+pi) = -1.
4^2 + b^2 = 12^2
16 + b^2 = 144
B^2 = 144-16
B^2 = 128
B= 11.3
Answer:
Rectangle
Step-by-step explanation:
Well if point A is on (2,3) and you reflect it over the x axis point B would be located at (2,-3).
Then over the y axis point C would be located at (-2,-3), then reflecting that over the x axis point D is (-2,3)
<em><u>Points</u></em>
__________
A. (2,3)
B. (2,-3)
C. (-2,-3)
D. (-2,3)
__________
So graphing all these points we get a rectangle.
Because it has 4 sides that are 90 degrees and the sides opposite from each other are the same.
Answer is 2 x 4=8 this is a scientific property
