Answer:72,000
Step-by-step explanation:
= 4800 × 15
Answer:
The transformation is (y,-x)
Step-by-step explanation:
To know the mapping notation, we need to know the coordinates of the image and the pre-image
For the pre-image, we have;
A(3,8)
B(6,8)
C(6,2)
For the image, we have
A’( 8,-3)
B’ (8,-6)
C’ (2,-6)
So let us try and get the transformation from the coordinates
We can see that this is;
(x,y) to (y,-x)
A)
The four small squares are all 3x3, so the perimeter is 3+3+3+3 = 12.
12 * 4 = 48
We can find the perimeter of the large diamond shape using the Pythagorean theorem, a^2 + b^2 = c^2
a = 4
b = 4
4^2 + 4^2 = c^2
16 + 16 = c^2
32 = c^2
c = 5.65685425
So the perimeter of the large diamond shape is
5.65685425+5.65685425+5.65685425+5.65685425 = 22.627417
48+22.6 = 70.6
B)
The areas of the small squares are 3x3 = 9
9 * 4 = 36
The area of the large diamond shape is
5.65685425 * 5.65685425 = 32
36 + 32 = 68
