➷ Here are the steps to solving that problem:
(2x+1)^2
=(2x+1)(2x+1)
=(2x)(2x)+(2x)(1)+(1)(2x)+(1)(1)
=4x^2+2x+2x+1
=4x^2+4x+1

For this case we have a function of the form:
Where,
A: initial population of bacteria
b: growth rate
x: number of hours
Since the diameter is double every hour, then:
We must now look for the value of A.
To do this, we evaluate an ordered pair of the graph:
For (1, 2):
Clearing A we have:
Then, the function is given by:
For after 9 hours we have:
Answer:
the diameter of the bacteria after 9 hours is:
Answer:
1. 8.75
2. 3.48
Step-by-step explanation:
hope this helps :3
Hi!
Okay, so this actually isn't too bad! (For number 5) Just add the negative x over to get 2x. Then subtract 2 over to get -10. Then divide by 2 (-5) and you're done! For the rest, do the same thing. Get the x's on one side, get the regular numbers on the other, and divide! Hope that helped!
I would say a because you would divide distance by time giving you the rate 48mi/hr
