Okay, I just know the answer not the range:
330 divided by 55 is 6. It would take 6 hours.
Is 12 I think so !! try it
Answer:
See below
Step-by-step explanation:
Remember, we have two quantifiers, the existential quantifier ∃, and the universal quantifier ∀. The existential ∃ translates to English as "for some" or "there exists", whereas ∀ means "for all" or "every". We will also use the negation operator ¬.
First, let's write the proposition using quantifiers. "There is someone in this class who does not have a good attitude" translates to "(∃x)(¬S(x))". ∃x means that there exists a person in this class x. ¬S(x) means that x, the person that exists because of the quantifier, does not have a good attitude.
The negation is "¬(∃x)(¬S(x))" or equivalently "(∀x)(S(x))". To negate a proposition using quantifiers, change the quantifier (existential to universal and viceversa) and negate the predicate (in this case we negated ¬S(x)).
In English, "(∀x)(S(x))" means "Every person in this class has a good attitude".
By definition we have to:
d = v * t
where,
d: distance
v: speed
t: time
We have then that the speed is:
(360-210) = v * 2.5
Clearing we have:
v = (360-210) /2.5
v = 60 mph
We now write the generic equation of distance:
d (x) = 60x
Where,
x: time
Answer:
an equation that represents (x), the distance Ainsley is from Orlando after x hours is:
d (x) = 60x
