Answer:
A consumer organization estimates that over a 1-year period 16% of cars will need to be repaired once, 9% will need repairs twice, and 3% will require three or more repairs..
We have the cars that do not need repair =
%
(16+9+3=28% cars need repair of some sort)
What is the probability that :
a) neither will need repair?
=> 
b) both will need repair?
=> 
c) at least one car will need repair?
=> 
=> 
You need to tell how many centimeters that enclosure is. Width and length
2sinxcosx is equal to sin(2x)
therefore,
= sin(2x)/cos(2x)
= tan(2x) (ANSWER)
First, we are going to add
from both sides of the equation:
Next, we are going to use the trig identity:
to rewrite our expression:
Finally, using our unitary circle, we can infer that
from 0 to
when
and
We can conclude that the solutions of the equation <span>cos (x) tan (x) -1/2=0 over the interval [0,2π] are: </span>
