The length of an arc, by definition is given by:
s = R * theta
Where,
R: radio
theta: angle of the bow.
We then have to replace:
s = (6) * (135 * (pi / 180))
s = 14.1 in
Answer:
The length of the arc s is:
s = 14.1 in
Answer:
See the argument below
Step-by-step explanation:
I will give the argument in symbolic form, using rules of inference.
First, let's conclude c.
(1)⇒a by simplification of conjunction
a⇒¬(¬a) by double negation
¬(¬a)∧(2)⇒¬(¬c) by Modus tollens
¬(¬c)⇒c by double negation
Now, the premise (5) is equivalent to ¬d∧¬h which is one of De Morgan's laws. From simplification, we conclude ¬h. We also concluded c before, then by adjunction, we conclude c∧¬h.
An alternative approach to De Morgan's law is the following:
By contradiction proof, assume h is true.
h⇒d∨h by addition
(5)∧(d∨h)⇒¬(d∨h)∧(d∨h), a contradiction. Hence we conclude ¬h.
Answer:
54.3m
Step-by-step explanation:
h = distance above sea level
d = distance he can sea above sea level
d = 3.57h
h = 15.21m
d = ?
d = 3.57 × 15.21
d = 54.2997m approximately 54.3m
The person can see up to a distance of 54.3m
6% is less than 1, so it can't be any whole number.
