Answer:
The number of bacteria in 0.25 mL is 6.25 x 10^3.
Step-by-step explanation:
5 liter flask contains 1.25 x 10^8 bacteria.
So, 1liter flask contains = 
Now
0.25 mL contains = 
The third term in an arithmetic sequence is 58 and the fifth term is 90. if the first term is a1, which is an equation for the nth term of this sequence?
1. an = 8n + 10
2. an = 8n − 14
☆☆☆☆☆☆☆☆☆☆☆☆☆☆☆☆☆☆3. an = 16n + 10
4. an = 16n − 38
Answer:
Yes
Step-by-step explanation:
3.212 x 10^4
=> 3.212 x 10000
=> 32.12 x 1000
=> 321.2 x 100
=> 3212 x 10
=> 32120 x 1
=> 32120
Answer:
32.2683333333
Step-by-step explanation:
For this case we have the following system of equations:
5x + 3y = 17
-8x - 3y = 9
We can rewrite the system like:
Ax = b
Where,
A = [5 3; -8 -3]
b = [17; 9]
x = [x; y]
The determinant of matrix A is given by:
lAl = ((5) * (- 3)) - ((3) * (- 8))
lAl = (-15) - (-24)
lAl = -15 + 24
lAl = 9
Answer:
The determinant for solving this linear system is:
lAl = 9
