Answer:

Step-by-step explanation:
Given: a graph
To find: the average rate of change of the amount of the element over the 10-minute experiment
Solution:
A rate of change of one quantity with respect to another quantity is known as rate of change. If y is the dependent variable and x is the independent variable then average rate of change = change in y /change in x.
From the graph, 
change in x (time) =  minutes
 minutes
change in y ( amount of the element) =  g
 g
So, average rate of change = 
 
        
             
        
        
        
Answer:
Pedro got 1520 base hits and Ricky got 1243.
Step-by-step explanation:
This question can be solved by a system of equations.
I am going to say that:
x is the number of base hits that Pedro got.
y is the number of base hits that Ricky got.
Pedro and Ricky got 2673 base hits last season.
This means that 
Pedro had 277 more hits than Ricky.
This means that 
Replacing in the first equation






Pedro got 1520 base hits and Ricky got 1243.
 
        
             
        
        
        
You graph slope by going up and over based on what number you have as the slope. The starting point is the y intercept
        
             
        
        
        
Answer:
D. 1/4^5
Step-by-step explanation:
when you add the two, you get 4^-5. since you cannot take a number to a negative power, you have to change the equation to the inverse which is 1/4^5
