1) RED will be rotated 90° counterclockwise around the origin.
2) The coordinates of R'E'D' will be R'(2, 2); E'(0, 4) and F'(0, 0). The rule for a 90° counterclockwise rotation about the origin is that the coordinates (x, y) are mapped to (-y, x).
3) An isometric transformation is one in which the angles between sides and the distances of each side are preserved between the pre-image and the image. This means the angle measures and side lengths will be the same. Therefore the image will be similar to the pre-image, as the angle measures will be the same and the side lengths will be proportional.
Answer:
75.95cm
Step-by-step explanation:
<u>4.9 multiplied by 15 will represent the 15</u> <u>seconds</u>
4.9 • 15 = 73.5
<u>4.9 divided by 2 will equal the 1/2 seconds</u>
4.9 ÷ 2 = 2.45
<u>add them all together</u>
73.5 + 2.45 = 75.95 cm

Answer:
4 parameters are necessary to specify all solutions and correspond to the number of free variables of the system.
Step-by-step explanation:
Remember that the number of free variables of a system is equal to m-rank(A) where m is the number of unknowns variables and A is the matrix of the system.
Since the system is consistent and the rank of the matrix is 3 then echelon form of the augmented matrix has two rows of zeros.
Then m-rank(A)=7-3=4.
Answer: Angles are used in daily life. Engineers and architects use angles for designs, roads, buildings and sporting facilities. Carpenters use angles to make chairs, tables and sofas. Artists use their knowledge of angles to sketch portraits and paintings.
