<span>if isabel runs 7 miles in 50 minutes, then you know she runs 7/50 miles in one minute, right? So multiply that by the number of minutes she did run, and you can find the distance: 
</span><span> 7 
 ------ x 75 = 
 50 
 525 
 ------ 
 50 
</span><span> If you plug that fraction into your calculator, you get 10.5, so 10 and a half miles.</span>

   cos ∠ROQ = sin ∠QOP
 
        
             
        
        
        
Answer:
<h2>It's not a function.</h2>
Step-by-step explanation:
A function is a process or a relation that associates each element x of a set X, to a single element y of another set Y.
We have:
{(3, -2), (1, 2), (-1, -4), (-1, 2)}
for x = -1 are two values of y = -4 and y = 2. Therefore this realtion is not a function.
