15. Consider the diagram. Circle Q has a radius of 2 and Circle T has a radius of 7. Use transformations to decide if circles Q and T are similar. Choose the answer with the best explanation. A. They are similar because if there is a sequence of transformations that maps one figure onto another, then the figures are similar. Translate the center of Circle Q to point T. Then, dilate the radius of 7 7 Circle Q by a scale factor of B. They are similar because if there is a sequence of transformations that maps one figure onto another, then the figures 2 are similar. Translate the center of Circle Q to point T. Then, dilate the radius of Circle Q by a scale factor of - 7 C. They are similar because if there is a sequence of transformations that maps one figure onto another, then the figures are similar. Translate the center of Circle Q to point T. Then, rotate the radius of Circle Q 180° around point T. D. Circle Q and Circle T are not similar.
Permutations and Combinations
If there are 5 dishes, they can be relished in any order at a time. In permutation, it should be in a particular order. In combination, the order does not matter. Take 3 letters a, b, and c. The possible ways of pairing any two letters are ab, bc, ac, ba, cb and ca. It is in a particular order. So, this can be called the permutation of a, b, and c. But if the order does not matter then ab is the same as ba. Similarly, bc is the same as cb and ac is the same as ca. Here the list has ab, bc, and ac alone. This can be called the combination of a, b, and c.
Counting Theory
The fundamental counting principle is a rule that is used to count the total number of possible outcomes in a given situation.
