Which of the following study design categories focuses on observing and documenting behavior?
- Several various kinds of non-experimental studies in which behavior is routinely observed and documented are collectively referred to as observational research.
- A variable or combination of variables must be described in order to be the focus of observational research.
What are some examples of biological processes that have an impact on development?
- An individual's physical makeup can alter as a result of biological processes.
- and several biological processes that have an impact on development include weight gain, changes in motor skills, puberty's hormonal changes, and cardiovascular deterioration.

Answer:
East and west side= 5 foot
South and north side = 10 foot
Area = 50 foot^2
Step-by-step explanation:
We know that:
East and west fencing cost= $4 per foot
South and north fencing cost $2 per foot
So, we can consider:
x= south and north fencing
y= east and west fencing
Then we create an equation representing the case:
Total cost = (south+north)*$2 + (east+west)*$4
80 =(x+x)*2 + (y+y)*4
80 =(2x)*2 + (2y)*4
80 =4x + 8y
80 =4*(x+2y)
80/4 =x+2y
20 = x+2y
x= 20-2y
We can calculate the area as width * length:
Area = length * width
Area= x * y
Area= (20 - 2y) * y
area= 20y - 2y^2
Next step is to find the "y" value for the maximum area so you can derivate and equal to 0 to find maximums:
d(20y - 2y^2)/dy = 20 - 2*2y = 20 - 4y
20 - 4y = 0
20 = 4y
y = 20/4
y = 5
If y = 5, then:
x = 20 - 2y
x = 20 - 2*5
x = 20 - 10
x = 10
X = 21
ABC has a scale factor of 3, so each value is x3
7x3 = 21
The answer is 21.4 ft hope this helps
Answer:
Step-by-step explanation:
The amount that Alexa owes after t weeks is given by a linear equation in the following format:
In which L(0) is the initial amount borrowed and b is how much is paid per week.
Alexa agreed to pay back her friend $10 per week and originally borrowed $170.
This means that, respectivelly, . So
