90-75=15, which is the difference between the two. Hope this helps.
Answer:
That's incorrect. The simplest way to show this is by evaluating the functions at a given point. Let's say x=0, then:
Sin(-x) = Sin(0) = 0
-cos x = -cos (0) = -1
Therefore, Sin(-x)≠-cos x.
Answer:
14 knots
Step-by-step explanation:
We know the speed (55 knots) is 6 more than 3.5 times the winner of the monohull in the 2007 tournament.
So let's set the variable for the speed of the monohull to <em>m</em>. Now, let's set up an equation:
We can solve this by first subtracting 6 from both sides to get:
Dividing both sides by 3.5 we get:
That means that the top speed of the monohull in the 2007 tournament was 14 knots
