Answer:AlF3
Step-by-step explanation:
Given that triangle <span>STU
is reflected once to map onto
triangle S'T'U'.
Given that triangle STU has
vertices S(8, 6), T(2, 2), U(5, 1).
If vertex T' is at
(2, −2), this means that triangle STU is refrected across the x-axis.
A refrection across the x-axis results in an image that has the same x-value as the pre-image but a y-value that has the opposite sign of the y-value of the pre image.
Thus, a point, say (x, y), refrected over the x-axis will result in an image with coordinate (x, -y)
Therefore, given that the coordinate of S is (8, 6), then the coordinates of vertex S'</span> is (8, -6).
Circumference = 2pi r
80/360 x 2pi x r = 24pi
r = 54
Answer:
The actual perimeter of the field is 352 meters
Step-by-step explanation:
Given;
the perimeter of a field is 0.352 meters
the actual perimeter of the field is 1,000 times as large
let the perimeter of the field = p
the the actual perimeter of the field = T
Given;
P = 0.352 m
T = 1000 x p
T = 1000 x 0.352
T = 352 m
Therefore, the actual perimeter of the field is 352 meters
