Let P(x) be the statement"x= x2", If the domain consists of the integers, what are these truth values? (a) P(0) (b) P(1) (c) P(2

jeka57 [31]

Answer: i guess the problem is with P(x) => "x = $x^{2}$ ", then P(x) is true if that equality is true, and is false if the equality is false.

so lets see case for case.

a) x = 0, and $0^{2}$ = 0. So p(0) is true.

b) x = 1 and $1^{2}$ = 1, so P(1) is true.

c) x = 2, and $2^{2}$ = 4, and 2 ≠ 4, then P(2) is false.

d) x= -1 and $1^{2}$ = 1, and 1 ≠ -1, so P(-1) is false.

Prove that C(50,3) + C(50,4) = C(51,4)

valkas [14]

By definition of the binomial coefficient,

$C(n,k) = \dfrac{n!}{k!(n-k)!}$

so we have

$C(50,3) + C(50,4) = \dfrac{50!}{3!47!} + \dfrac{50!}{4!46!} \\\\ = \dfrac{50!}{3!46!} \left(\dfrac1{47} + \dfrac14\right) \\\\ = \dfrac{50!}{3!46!} \times \dfrac{51}{188} \\\\ = \dfrac{51!}{3!46!} \times \dfrac1{4\times47} \\\\ = \dfrac{51!}{4!47!} \\\\ = \dfrac{51!}{4!(51-4)!} = C(51,4)$
