Answer:
4033
Step-by-step explanation:
An easy way to solve this problem is to notice the numerator, 2017^4-2016^4 resembles the special product a^2 - b^2. In this case, 2017^4 is a^2 and 2016^4 is b^2. We can set up equations to solve for a and b:
a^2 = 2017^4
a = 2017^2
b^2 = 2016^4
b = 2016^2
Now, the special product a^2 - b^2 factors to (a + b)(a - b), so we can substitute that for the numerator:
<h3>

</h3>
We can notice that both the numerator and denominator contain 2017^2 + 2016^2, so we can divide by  which is just one, and will simplify the fraction to just:
 which is just one, and will simplify the fraction to just:
2017^2 - 2016^2
This again is just the special product a^2 - b^2, but in this case a is 2017 and b is 2016. Using this we can factor it:
(2017 + 2016)(2017 - 2016)
And, without using a calculator, this is easy to simplify:
(4033)(1)

Answer:
The answer to your question is x = 15
Step-by-step explanation:
Use proportions to solve this problem
                               
Solve for "x"
                                           x = 
Simplification
                                           x = 
Result
                                          x = 15                                                   
 
        
             
        
        
        
Answer: 
Option D(No because the wrist circumference of 16 cm is paired with two heights.
Step-by-step explanation:
In the given graph we have  set of points representing the wrist circumferences and heights of six students in Alyssa’s classroom. 
x axis  represents the wrist circumference while  y axis represent the height.
Any relation is called a function if for one value of x we have only one value of y. If the graph passes the vertical line test that is if a vertical line drawn touches the graph at only one point then the graph is called a function.In the given graph for x value x=16 there are two y values 162 and 165.So the graph is not a function.
Among all the options Option D(No because the wrist circumference of 16 cm is paired with two heights.) is the right answer.
 
        
                    
             
        
        
        
An equivalent ratio of 64:60 is 16:15.
