By simplifying given phrase "twice the sum of a number cubed and nine" and evaluating it for r = 3 we got that Jessica done it correctly
<h3>What is cube of any number ?</h3>
Cube of any number means multiplying that number with itself 3 times.
For example
Here given phrase is
twice the sum of a number cubed and nine
let number be r
We can write it as
Now evaluating it for r=3
Now we can simplify it as
By simplifying given phrase "twice the sum of a number cubed and nine" and evaluating it for r = 3 we got that Jessica done it correctly

Answer:
y = 340e^0.0427276t ; 908
Step-by-step explanation:
Given that :
t = time in days since study began
Number of bacteria after 11 days = 544
y = number of bacteria at time t
Exponential growth model:
y = ae^rt
Where a = initial amount ; r = Growth rate
y = 544 ; t = 11 ; a = 340
544 = 340*e^11t
544/340 = e^11t
1.6 = e^11t
Take the In of both sides
In(1.6) = 11t
0.4700036 = 11t
t = 0.4700036 / 11
t = 0.0427276
y = 340e^0.0427276t
Number of bacteria after 23 days :
Using the formula above :
t = 23
y = 340e^0.0427276(23)
y = 340 * 2.6717529
y = 908.39600
y = 908
Answer:
3
Step-by-step explanation:
Note that 12 is obtained by multiplying the first term (4) by 3; 36 is obtained by mult. the preceding term (12) by 3, and so on. Thus, the common ratio is 3.
