For this case we have the following quadratic equation:

Rewriting the equation we have:

From here, we have:

Substituting values in the quadratic equation we have:
Rewriting the equation we have:
Answer:
The values of x are given by:

Answer:
1. 10/21
2. 11/21
Step-by-step explanation:
Answer:
see below
Step-by-step explanation:
g(x) = (x+2)^2 -1
The function is in the form
g(x) = a(x-h)^2 +k
where (h,k) is the vertex of the parabola
Rewriting
g(x) = (x+2)^2 -1
= (x--2)^2 + -1
The vertex is (-2,-1)
We can find another point by letting x =0
g(0) = (0+2)^2 -1
=2^2 -1
=4-1 =3
The second point is (0,3)
Answer:
5/6 oz/pamphlet
Step-by-step explanation:
Find the unit rate:
7 1/2 oz 15 oz 1
--------------------- = ------------- * -------------------- = 15/18 oz/pamphlet, or
9 pamphlets 2 9 pamphlets
5/6 oz/pamphlet
It will take 5.83 hours for the bacteria to reach 1119.
<h3>What is exponential Growth ?</h3>
Exponential growth is when the quantity increases according to the function

It is given in the question that
Initial number of Bacteria is 50
After 3 hours the bacteria has increased to 80
The bacterial growth is an exponential growth


Applying log on both sides
1.6 = 3*k
k = 1.6/3
k = 0.533
if this rate of growth continues, how much more time will it take for the number of bacteria to reach 1119

Therefore it will take 5.83 hours for the bacteria to reach 1119.
