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:
2.60
Step-by-step explanation:
Given that:
n = 1600


The test statistics can be computed as:





Consider the equation:

Subtracting '4' from both the sides of the equation, we get as


Squaring on both the sides of the equation, we get


Subtracting '2' from both the sides of the equation, we get

x=14
Since, An extraneous solution is a solution that arises from the solving process that is not really a solution at all. But, in this equation x=14 is the solution of the given equation.
Hence, it is not an extraneous solution.

Answer: 12</h3>
========================================================
Explanation:
You can use the AAS (angle angle side) theorem to prove that triangle ABD is congruent to triangle CBD.
From there, we can then say that AD and DC are the same length
AD = DC
3y+6 = 5y-18
3y-5y = -18-6
-2y = -24
y = (-24)/(-2)
y = 12
Note that if

, then

, and so we can collapse the system of ODEs into a linear ODE:


which is a pretty standard linear ODE with constant coefficients. We have characteristic equation

so that the characteristic solution is

Now let's suppose the particular solution is

. Then

and so

Thus the general solution for

is

and you can find the solution

by simply differentiating

.
