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

<h2>Hello!</h2>

The answer is:

The correct option is:

A. $0.49

From the statement, we know that the iHome is used on average three hours a day, and we are asked to find the cost for a week, so first, we need to calculate the total hours that the iHome is used for, and then, calculate the kilowatt-hour consumption rate.

$TotalTime_{week}=3\frac{hours}{day} *7days=21hours$
