Answer:
   2.8¢, true
Step-by-step explanation:
The value of copper in a penny is reportedly about ...
   (0.95 × 3.11 g)×(1 oz)/(28.35 g)×($0.27/oz) ≈ $0.028
Today, the value of the copper in a pre-1982 penny is about 2.8¢, more than double the value of the penny as legal tender.
The claim is true.
 
        
             
        
        
        
speed = distance / time = 100 m / 50 s = 2 m/sec
Juan average speed is 2 m / sec
 
        
                    
             
        
        
        
With the exception of the form f(x) = ax + b, non-linear graph equation can take any form.See graph in photo attached.
<h3>What is non linear function and its graph?</h3>
As the name suggests, a nonlinear function is one that is NOT linear.
To put it another way, a nonlinear function's graph is not a linear. In other words, its graph is not limited to being a line.
Any function whose graph is not a straight line should be considered a nonlinear function since a nonlinear function is one that is NOT linear.
Since none of the graphs in the following figure are straight lines, they all illustrate nonlinear functions.

The answer is 6,811.1
The reason the 0 moved up to a 1 is because the number in the hundredth place was 5 or over. If it were 4 or under, then it would have remained a 0.
 
        
             
        
        
        
Answer:
x² - 10x + 21
Explanation:
To answer this question, we will simply multiply each term from the first bracket by each term from the second and then combine like terms to get the final expression.
This can be done as follows:
(x - 3)(x - 7)
x(x) + x(-7) -3(x) -3(-7)
x² - 7x - 3x + 21
x² - 10x + 21
Hope this helps :)
