Answer:
The average rate of change on the given interval is 9/70
Step-by-step explanation:
Here, we are to find the average rate of change of the function on the given interval
We proceed as follows;
 on an interval [a,b] , we can find the average rate of change using the formula;
f(b) - f(a)/b-a
From the question;
a = 0
b = 3
f(0) = -3/5
f(3) = -3/14
Substituting the values, we have;
-3/14-(-3/5)/3-0
= 3/5-3/14/3
= (42-15)/70/3
= 27/70/3
= 27/70 * 1/3 = 9/70
 
        
             
        
        
        
Answer:
180 Vertical angles are opposite angles that share only a vertex.  Since ∠3 is adjacent to both ∠1 and ∠2, this means that ∠3 shares a side and vertex with both of these angles.
This means that ∠3 and ∠1 form a straight line; this makes them a linear pair, which makes their sum 180°.

Answer:
Step-by-step explanation:
1. 10² + 7² = x²
 149 = x²
 x = √149
2. x² + 19² = 21²
 x² = 21² -  19² = 80
 x = √80 = 4√5
3. x² + 16² = 27²
 x² = 27² - 16² = 473
 x = √473
4. 5.3² + 12.8² = x²
 191.93 = x²
 x = √191.93
5. 9² + 20² = x²
 481 = x²
 x = √481
6. 31 = x + 2√(19²-17²) = x + 2·6√2 = x + 12√2
 x = 31 - 12√2
