Answer:
354.
Step-by-step explanation:
Exponential growth:
380 = 200e^(k*9) where k is a constant to be found.
e^9k = 380/200 = 19/10
ln e^9k = ln 1.9
9k = ln 1.9
k = ln 1.9 / 9
k = 0.071
After 8 hours:
Number of bacteria =
200*e^(8*0.071)
= 354.
a) <u>n² + 6 </u>
~Here n is the number of term. So, put n = 1,2,3,4.... to get the term.
- If n = 1, first term = 1² + 6 = 7
- n = 2, second term = 10
- n = 3, third temm = 15
- n = 4, fourth term = 22
- n = 10, tenth term = 106
b) <u>3n²</u>
- If n = 1, first term = 3
- n = 2, second term = 12
- n = 3, third term = 27
- n = 4, fourth term = 48
- n = 10, tenth term = 300
This is very confusing what are you trying to figure out give a little more information and I will be more than happy to hell you
Answer:
x = 14.5
Step-by-step explanation:
Exterior angle thm
<C = <D
7x - 2 = 9x - 31
7x - 9x = -31 + 2
-2x = -29
x = 14.5
Answer: $32.45
Step-by-step explanation:
Because....
55% × 59 = $32.45
You could also write 55% as 0.55.
So it will look like this :
0.55 × 59 = 32.45.
It will still give you the same answer :)
* Hopefully tis helps:) Mark me the brainliest:)!!
