The sum of an infinite geometric series is of the form: where is the first term and is the ratio whose absolute value is less than 1. We know that the second term is the first term multiplied by the ratio. In other words: Thus, the sum is the following: Since we want the minimum value of this expression, we want the maximum value ...Solution 1 (Coordinate Geometry) First, we will define point as the origin. Then, we will find the equations of the following three lines: , , and . The slopes of these lines are , , and , respectively. Next, we will find the equations of , , and .

Another way to solve this problem is using cases. Though this may seem tedious, we only have to do one case since the area enclosed is symmetrical. The equation for this figure is To make this as easy as possible, we can make both and positive. Simplifying the equation for and being positive, we get the equation. Solution 2 (Proving that is division) If the given conditions hold for all nonzero numbers and , Let From the first two givens, this implies that. From this equation simply becomes. Let Substituting this into the first two conditions, we see that. Substituting , the second equation becomes. Since and are nonzero, we can divide by which yields, Solution 1 (Coordinate Geometry) First, we will define point as the origin. Then, we will find the equations of the following three lines: , , and . The slopes of these lines are , , and , respectively. Next, we will find the equations of , , and . They are as follows: After drawing in altitudes to from , , and , we see that because of similar ... Solution 3 (Fast And Clean) The median of the sequence is either an integer or a half integer. Let , then . 1) because the integers in the sequence are all positive, and ; 2) If is odd then is an integer, is even; if is even then is a half integer, is odd. Therefore, and have opposite parity.Solution 1. The product will be even if at least one selected number is even, and odd if none are. Using complementary counting, the chance that both numbers are odd is , so the answer is which is . An alternate way to finish: Since it is odd if none are even, the probability is . ~Alternate solve by JH. L.Solution 4 (Trigonometry Bash) Construct quadrilateral on the circle with being the missing side (Notice that since the side length is less than the radius, it will be very small on the top of the circle). Now, draw the radii from center to and . Apply the law of cosines on ; let . The 2016 AMC 10B was held on Feb. 17, 2016. Over 250,000 students from over 4,100 U.S. and international schools attended the 2016 AMC 10B contest and found it very fun and rewarding. Top 10, well-known U.S. universities and colleges, including internationally recognized U.S. technical institutions, ask for AMC scores on their application forms.Solution 1. The numbers are and . Note that only can be zero, the numbers , , and cannot start with a zero, and . To form the sequence, we need . This can be rearranged as . Notice that since the left-hand side is a multiple of , the right-hand side can only be or . (A value of would contradict .) Therefore we have two cases: and . If , then , so .2000. 110. 92.

If we attempt to maximize this cube in any given way, for example making sure that the sides with 5,6 and 7 all meet at one single corner, the first two answers clearly are out of bounds. Now notice the fact that any three given sides will always meet at one of the eight points.Solution. The sum of the ages of the cousins is times the mean, or . There are an even number of cousins, so there is no single median, so must be the mean of the two in the middle. Therefore the sum of the ages of the two in the middle is . Subtracting from produces .The AMC 10 and AMC 12 are both 25-question, 75-minute, multiple-choice examinations in high school mathematics designed to promote the development and enhancement of problem-solving skills.
