解析 51. 7x2−4x√3x2−3−7=0 (√3x2−3)2−2(√3x2−3)(2x)+(2x)2=4 (√3x2−3−2x)2=4 所以√3x2−3−2x=2或√3x2−3−2x=−2. 解之分别得x=−1、x=−7、x=1或x=7, 经验算后舍去x=−7....
I don't see how the formula you posted applies to the picture with the squares. That formula is for calculating the number of combinations of something, but when you only want a subset (that's what the r is for). You don't "use combinations" for that formula. The number of combinati...

Asked by PrivateSeahorse8209 Find the equation of the least-squares regression line ŷ and the linear correlation coefficient r for the given data. Round the constants, a, b, and r, to the nearest hundredth. {(2, −4), (4, −5), (6, ...
Square rootof a number is a value, which on multiplication by itself, gives the original number. The square root is an inverse method of squaring a number. Hence,squares and square rootsare related concepts. Suppose x is the square root of y, then it is represented as x=√y, or we ...

Add a 4th sphere (or more) to the mix, and if these are measured points with some noise in them, then there will be probably no exact solution. One can actually formulate the problem in a linear least squares sense. I imagine there must be some code on...
289 and 784 are perfect squares. The square root of 289 is 17; the square root of 784 is 28. Perfect squares can only have 0, 1, 4, 5, 6, 9 on the ones place. We can filter some of the numbers with the above pattern. Then we can filter others by finding the perfect squares...
