Answer:
The black curve is the graph for given function.
Step-by-step explanation:
We are given the following function in the question:
We have to graph this function.
Properties of function:
- The given function is an exponential function of the form
, where b is the base and x can be any real number. - Here,
- It passes through the point (0,1).
- Since
, the graph of function will will increase as we move from left to right. - The domain for given function is all real numbers.
- The range for the given function is
The attached image shows the graph for the given function.
Answer:
a) The variable of the study is: milligrams of nitrogen per liter of water.
This is the amount that needs to be measured and analyzed to reach conclusions in the study.
b) The variable is quantitative. The quantitative variables are those that represent quantities. This variables can be measured on a continuous or discrete scale. Then, all the variables that you can measure or count are quantitative variables(height of trees, number of passengers per car, wind speed, milligrams of nitrogen per liter, etc). On the other hand, qualitative variables are those that can’ t be measured, and they represent attributes, like apple colors (red, green), size of trousers (small, medium, large) and so on.
c) The population under study is the milligrams of nitrogen per liter of water that are in the entire lake. You can estimate the parameters of the population by taking samples (In the example, 28 samples are taken).
Answer:
20
Step-by-step explanation:
The perimeter is the sum of the side lengths:
4 + 6 + 4 + 6 = 20 . . . . units
The answer is <em>p</em> = -6
Answer:
w=12
l=20
Step-by-step explanation:
The area can be found using the following equation:
Given the information provided, we are also told the following:
Therefore, we can plug in our length and our area:
We can solve by using the quadratic formula.
w=12, so w+8=20.
