Answer: Robert and Chris can skate 10 miles in 45 minutes.
Step-by-step explanation:
Let's start by finding the unit rate.
Robert and Chris can skate of a mile in 1 minute. Now we can multiply both by 45 to see how far the can go in 45 minutes.
45x1=45
The can skate 10 miles in 45 minutes.
The expression that is equivalent to is .
Given trigonometric expression is:
<h3>What is the
value of
?</h3>
The value of is because lies in the second quadrant and the cosine function is negative in the second quadrant.
So,
The range of sine and cosine functions is the same i.e. [-1,1].
Both the functions are periodic functions with periods 2π.
Hence, the expression that is equivalent to is .

Well, notice the picture below
recall cosine is adjacent over hypotenuse
what's the hypotenuse? well, you can just use the pythagorean theorem to get "c" or hypotenuse
