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:
slope = -
Step-by-step explanation:
Calculate the slope m using the slope formula
m =
with (x₁, y₁ ) = (- 5, 0) and (x₂, y₂ ) = (0, - 7 ) ← 2 points on the line
m = =
=
= -
