Answer: A) The initial number of bacteria is 350.
Step-by-step explanation:
Exponential growth equation: 
, where A=Initial value, r= growth rate. (i)
Given: A bacteria sample can be modeled by the function 
which gives the number of bacteria in the sample at the end of x days.
Here, 
Compare this equation to (i) , we get A = 350 and r= 0.20 = 20% (growth rate)
So, the best interpretation of one of the values in this function are:
A) The initial number of bacteria is 350.
Answer:
One way to factor equation is to find the zeros. Its obvious that x=-1 is solution for this. So one factor is (x+1)
the next factor should include 2x at first (because we have 2x^2 in the equation which can not be made any other way)
Let's suppose the factor is (x+1)(2x+b)
Since we do not know what is b open the brackets 2x^2+bx+2x+b. If this is equal to 2x^2+5x+3 then b=3. We are left with (x+1)(2x+3)=2(x+1)(x+3/2)
Would go for other shorter solutions, but they require some deeper understanding like Horner's scheme,Fermat's Theorem or even deeper which I assume You will not understand)
It will be C cause you divid 15 and 6
Answer:
The second one is the best answer to your question
Answer: 
Step-by-step explanation:
For this exercise it is important to remember the following:
1. By definition, the "Product" is the result of a multiplication.
2. The "Difference" is defined as the result of a subtraction.
3. The Distributive property states that:
Keeping the above on mind, you know that:
"The difference of 
and 
" can be represented with the following expression:
Therefore, "The product of -13 and the difference of and " can be represented with this expression:
Finally, you must apply the Distributive property in order to simplify the expression. You get:
