【题目】For all real numbers a, b and c it is true thata(b+c)=ab+ac and this is known as the distributive law.(1)'Make up' three 2 ×2 matrices , s and 。 and(2) Now let A=[a/c] . =[P_5][0nde=[(10)/y) ] and prove that in general A(B +C)=AB +AC. (...
Use the following matrices, where all elements are real numbers, to show that each statement is true for 2*2 matrices.A=(bmatrix)a_(11)&a_(12)a_(21)&a_(22)(bmatrix), B=(bmatrix)b_(11)&b_(12)b_(21)&b_(22)(bmatrix), and C=(bmatrix)c_(11)&c_(12)c_(21)&c_(22...
选项 A 中,分母不能为 0,所以 x - 1 ≠ 0,即 x ≠ 1,定义域不是所有实数。选项 B 中,根号下的数须大于等于 0,即 x - 1 ≥ 0,x ≥ 1,定义域不是所有实数。选项 C 中,对于任何实数 x,x^2 都有意义,定义域为所有实数。选项 D 中,对数中的真数须大于 0,即 x - 1 > 0,x > 1,定义...
The mean is (4+6+8+17+x)/5=(35+x)/5.There are three possibilities for the median: it is either 6,8, or x. Let's start with 6. (35+x)/5=6 has solution x=-5, and the sequence is -5,4,6,8,17, which does have median 6, so this is a valid solution.Now let the ...
