Answer:
no its 200
Step-by-step explanation:
50 *2=100
500-100=400 miles
so 400/2=200
Answer: 3
Step-by-step explanation:
Answer:
3271
Step-by-step explanation:
In this problem, we have:
is the population of bacteria at the beginning, at time t = 0
After 2 hours, we have a number of bacteria equal to
This means that the growth of the population for every 2 hours is:
This means that we can write an expression for the population after n pairs of hours as follows:
where
n is the number of "pairs of hours" passed from t = 0
In this problem, we want to find the population of bacteria after 13 hours, which contains a number of pairs of hours equal to:
Therefore, substituting 6.5 in the expression, we find the population after 13 hours:
Answer:
-4x^2-6x+6
Step-by-step explanation:
We are asked to subtract g from f.
So the problem is:
[8x^2-2x+3]-[12x^2+4x-3]
So I'm going to distribute and write without [].
8x^2-2x+3-12x^2-4x+3
Now I'm going to pair up any like terms:
8x^2-12x^2-2x-4x+3+3
Simplifying:
-4x^2-6x+6
Answer: (0,1)
Step-by-step explanation:
3*(1+x)<x+6
3*1+3*x<x+6
3+3x<x+6
-x -x
2x+3<6
-3 -3
2x<3
x<3/2
so x<1.5
on (0,1) the inequality is true
