Answer:
The function is y = 40 * 2^(x/2)
The graph is in the image attached
Step-by-step explanation:
The function that models this growth is an exponencial function, that can be described with the following equation:
y = a * b^(x/n)
Where a is the inicial value, b is the rate of growth, x is the time and n is the relation between the time and the rate (the rate occurs for every two hours, so n = 2).
Then, using a = 40, r = 2 and n = 2, we have:
y = 40 * 2^(x/2)
If we plot this function, we have the graph shown in the image attached,
It is an exponencial graph, where the value of y increases very fast in relation to the increase of x.
Answer:
n=-5
Step-by-step explanation:
Let "n" represent the unknown number.
So, the equation asks for 4n and two more, or +2, that is all equal to -18.
So, your equation will be:
First, subtract 2 from both sides:
Then, divide both sides by 4:
Therefore, n=-5.
