as per question statement
we need to set up an equation first
![p(t)=1200e^(0.052*t)](https://tex.z-dn.net/?f=%20p%28t%29%3D1200e%5E%280.052%2At%29%20)
they have given that it is relative to 1200 that means it starts to increase from 1200 at t=0 initially 1200 bacteria were present
we need to find population at t=6
we need to plug t=6 in p(t).
![P(6)=1200e^(0.052*6)=1639.38](https://tex.z-dn.net/?f=%20P%286%29%3D1200e%5E%280.052%2A6%29%3D1639.38%20%20)
1638.38 bacteria were present at that time t=6
Add all the numbers and divide by how many there are.
![\frac{10+31+36+36+38+42+47+48+49+52 }{10} = \frac{389}{10} =38.9](https://tex.z-dn.net/?f=%20%5Cfrac%7B10%2B31%2B36%2B36%2B38%2B42%2B47%2B48%2B49%2B52%20%7D%7B10%7D%20%3D%20%20%5Cfrac%7B389%7D%7B10%7D%20%3D38.9)
The mean is 38.9
Answer:
![- 7 = 1 \times ( - 7)](https://tex.z-dn.net/?f=%20-%207%20%3D%201%20%5Ctimes%20%28%20-%207%29)
<h2>The factors of (-7 ) is 1, -1 .</h2>
Answer:
B
Step-by-step explanation:
this equation is in the form of ax^2+bx+c
so a is 4, b is -9, and c is 8
Answer: 40.192 cm
Step-by-step explanation:
the formula for circumference is ![2\pi r](https://tex.z-dn.net/?f=2%5Cpi%20r)
In this case we are using 3.14 for pi and the radius is 6.4
![(2)(3.14)(6.4)\\(6.28)(6.4)\\40.192](https://tex.z-dn.net/?f=%282%29%283.14%29%286.4%29%5C%5C%286.28%29%286.4%29%5C%5C40.192)
