Answer:
The image of A(18, 9) after dilation by a scale factor of 1/3 will be: A'(6, 3).
Step-by-step explanation:
Let suppose the given point is A(18, 9)
We know that when an object is dilated by a scale factor, it gets reduced, stretched, or remains the same, depending upon the value of the scale factor.
- If the scale factor > 1, the image is enlarged
- If the scale factor is between 0 and 1, it gets shrunk
- If the scale factor = 1, the object and the image are congruent
Rule to calculate the dilation by a scale factor 1/3 centered at the origin
P(x, y) → P'(1/3x, 1/3y)
Here, P'(1/3, 1/3y) is the image of P(x, y).
- It means the coordinates of the image can be determined by multiplying the coordinates of the original point by 1/3.
Thus,
A(18, 9) → A'(1/3(18), 1/3(9)) = A'(6, 3)
Therefore, the image of A(18, 9) after dilation by a scale factor of 1/3 will be: A'(6, 3).
Answer:
Area=14.28 Perimeter= 14.28
Step-by-step explanation:
Area of a circle = (3.14) * r^2
radius = diameter/2
radius = 4/2
r = 2
A = (3.14) * 2^2
A = (3.14) * 4
A = 12.57
since it's a half circle though, 12.57/2 = 6.29
the area of the rectangle is bh, 4*2 = 8
6.29 + 8 = 14.28
area = 14.28
perimeter of a circle, or circumference = 2(3.14)r
C = 2(3.14) * 2
C = 6.28 * 2
C = 12.57
but again, since it's a half circle, 12.57/2 = 6.29
perimeter of a rectangle = 2(l + w)
p = 2(4 + 2)
p = 2(6)
p = 12
but because the perimeter is what's on the outside, we don't count the side connecting to the circle, so it'd be 12 - 4 = 8
6.29 + 8 = 14.28
perimeter = 14.28
