Answer:
m=6
Step-by-step explanation:
38+8m+4=90
42+8m=90
8m=90-42
8m=48
m=6
Using an exponential function, it is found that the colony will have 1344 bacteria after 8 days.
<h3>What is an exponential function?</h3>
An increasing exponential function is modeled by:

In which:
- A(0) is the initial value.
- r is the decay rate, as a decimal.
Considering the initial amount of 150, and the growth rate of 73% each 2 days, the equation is given by:

Hence, after 8 days, the amount of bacteria is given by:

Answer:
B
Step-by-step explanation:
Please see the answer in the picture attached below.
" From Step 1: We find that Angle N1 equals to 75 gradius => Answers A and C wrong. Answers B and D are left.
" From Step 4: We find that Angle N2 equals to 129 gradius => Answer B is true.
You don't need to find the exact value of the angle N3 in oder to choose the right answers from A,B,C,D.
Hope this answer can help you. Have a nice day!
