Answer:
Four hundredths 
In standard form - 
Step-by-step explanation:
Given : The green darner is one of the largest dragonflies.
 It weighs about four hundredths of an ounce.
To write : Four hundredths in standard form.
Solution : 
Standard form is when we write a larger number in a smaller way.
For example : 
So, according to question 
Largest dragonflies weighs about four hundredths of an ounce.
Four hundredths means 0.04 
In standard form - 
 
        
             
        
        
        
Answer:
The explicit form is 
Step-by-step explanation:
The explicit form of a geometric sequence is given by:

where an is the nth term, a is the first term of the sequence and r is the common ratio.
In this case:
a=162
The value of the common ratio is obtained by dividing one term by the previous term.
For the first and second terms:
108/162=2/3
For the second and third terms (In order to prove that 2/3 is the common ratio)
72/108=2/3
Therefore:
r=2/3
Replacing a and r in the formula:

 
        
             
        
        
        
Answer:
A) y² - 5y + 1
B) y² - 5y - 4
C) - 5y + 1
D) - 3y² - 4y - 6
Step-by-step explanation:
Let's call P the unkown polynomial and D the difference. In each case, the following must be true:
y² - 5y + 1 - P = D
<em>A)</em>
y² - 5y + 1 - P = 0
y² - 5y + 1 = P
<em>B)</em>
y² - 5y + 1 - P = 5
y² - 5y + 1 - 5 = P
y² - 5y - 4 = P
<em>C)</em>
y² - 5y + 1 - P = y²
y² - 5y + 1 - y² = P
- 5y + 1 = P
<em>D) </em>
y² - 5y + 1 - P = 4y² - y + 7
y² - 5y + 1 - 4y² + y - 7 = P
- 3y² - 4y - 6 = P
 
        
                    
             
        
        
        
80 divided by 64 then add % to ur answer
So then you will have your percentage to the dogs weight increase
