Rewrite each of the following sentences using logical connectives. Assume that each symbol!, x₀, n, x, B represents some fixed o
katrin [286]

Answer:

a) (f\  has\  a\  relative \ minimum \ at\  x_{0} ) ∧ (f\ is\ differenciable\ at\ x_{0} ) ⇒ f^{'} (x_{0} )=0.

b) (n\ is\ prime) ⇒ (n=2) ∨ (n\  is \ odd).

c) R\ is \ irreflexive\ ⇒ (R\ is\ symmetric) ∧ (R\ is\ transitive).

d) detB=0 ⇒ (B \ is\ square) ∧ (B\ is\ not\ invertible).

e) f\ has\ a\ critical\ point\ at \ x_{0} ⇔ (f^{'}(x_{0})=0) ∨ () \ f^{'}(x_{0}) \ does\ not\ exist.

f) 2n ∨ n>4 ⇒ 2.

g) 6\geq n-3 ⇔ n>4 ∨ n>10.

h) x \ is \ cauchy ⇒ x\ is\ convergent.

i) \lim_{x \to \ x_{0}} f(x)=f(x_{0}) ⇒ f\ is\ continous\  at \ x_{0}.

j) (f\ is\ diferenciable\ at\ x_{0}) ∧ (f\ is\ increasing\ at\ x_{0}) ⇒ f^{'}(x_{0})>0.

The product of a binomial and a trinomial is x3+3x2-x+2x2+6x-2 Which expression is equivalent to this
solong [7]
The answer is the first one.
Explanation:
X^3 stays the same because there are no other cubed numbers in the problem
Next you combine the x^2s
The x^2s are +3x^2 and +2x^2
Since they are both positive, you add them: 3x^2 + 2x^2 = 5x^2
Next you do the x values
-x and +6x, also known as 6x - x = 5x
Lastly, you just add in the -2 and get:
X^3 + 5x^2 + 5x - 2
