Its B just took the test the answer is B
Answer:
y=negative 2x+1
Step-by-step explanation:
rise over run negative 14 over 7 equals negative 2 and the y intercept is 1
First, subtract px2 from both sides.
Now you have:
x3 - px2 = (1 - p) x1
Next, divide both sides by (1 - p)
So now you have
x3 - px2/(1 - p) = x1
...as your final answer
*You can decide if you want to leave the parenthesis in your final answer, I left them there so it could be visible where I put them. :)
If my simplification is valid the answer is:
1.4 % growth each minute
I don’t feel like the representation
P = 120(1.82) is important in this certain problem.
So P the predicted number of bacteria is not practical with this problem.
Use the 82% per hour and divide it by 60 because there are 60 minutes in an hour.
When doing this you find the rate in which bacteria grows which is about 1.4%.
The prediction is about 1.82 percent for 120 something it’s not clarified, but I’m guessing that’s minutes.
So you can prove that the prediction is over the rate in which bacteria grows per minute.
Answer: Option C
![f(x) = x^2;\ k (x) = x ^ 2 -7](https://tex.z-dn.net/?f=f%28x%29%20%3D%20x%5E2%3B%5C%20k%20%28x%29%20%3D%20x%20%5E%202%20-7)
Step-by-step explanation:
Whenever we have a main function f(x) and we want to transform the graph of f(x) by moving it vertically then we apply the transformation:
![k (x) = f (x) + b](https://tex.z-dn.net/?f=k%20%28x%29%20%3D%20f%20%28x%29%20%2B%20b)
If
then the graph of k(x) will be the graph of f(x) displaced vertically b units down.
If
then the graph of k(x) will be the graph of f(x) displaced vertically b units upwards.
In this case we have
![f (x) = x ^ 2](https://tex.z-dn.net/?f=f%20%28x%29%20%3D%20x%20%5E%202)
We know that this function has its vertex in point (0,0).
Then, to move its vertex 7 units down we apply the transformation:
.
Then the function k(x) that will have its vertex 7 units below f(x) is
![k (x) = x ^ 2 -7](https://tex.z-dn.net/?f=k%20%28x%29%20%3D%20x%20%5E%202%20-7)
