I think you meant "y = 4 arccot (x)."
This is equivalent to:
y
---- = arccot x
4
and so cot (y/4) = x
First you have to have the absolute value isolated so the 2 has to be divided. Then set up the two cases and solve.
Answer:
Total songs = 15
Liked songs = 3
Un liked songs = 15-3=12
Find the probability that among the first two songs played
(a) You like both of them.
Probability that among the first two songs played you like both of them = 
(b) You like neither of them.
Probability that among the first two songs played you like neither of them = 
(c) You like exactly one of them.
Probability that among the first two songs played you like exactly one of them = 
(d) Redo (a)-(c) if a song can be replayed before all
(a) You like both of them. Would this be unusual?
Probability that among the first two songs played you like both of them = 
(b) You like neither of them.
Probability that among the first two songs played you like neither of them = 
(c) You like exactly one of them.
Probability that among the first two songs played you like exactly one of them = 
Answer:
105
Step-by-step explanation:
The interior angles must sum to 360
360-91+82-82 = 105
<u>answer (in words)</u>
FALSE. the coordinate pair (5, 2) is not a solution to the equation
. in order to figure out whether or not the statement is true or false, plug the
and
values from the coordinate pair (5, 2) into the given equation,
. if both sides of the equation end up equal, the coordinate pair is a solution to the equation. if not, the coordinate pair is not a solution to that equation.
<em>(i hope i explained that well enough, i'm better at explaining it algebraically as opposed to putting it into words lol)</em>
<u>answer (algebraic/steps for solving)</u>
first, plug in 5 for
in the equation
.
⇒ 
then plug in 2 for
.
⇒ 
now your equation is
. all that's left to do is to simplify. you can do this in whatever order you'd like, but i'll start with multiplying 2 · 5.
⇒ 
multiply 3 · 2.
⇒ 
add 10 + 6.
⇒ 
16 and 10 are <em>not</em> equal, therefore (5, 2) is not a solution to the equation
. in order for a coordinate pair to be the solution to an equation, both sides of the equation need to end up equal after solving and simplifying.
i hope this helps! have a great rest of your day <3
