The quantity of liters of the 2% and 66% solutions should you mix together is 4.75 and 11.25 liters.
let
- x = liters of 2% solution
- y = liters of 66% solution
x + y = 16
0.02x + 0.66y = 0.47 × 16
from (1)
x = 16 - y
Substitute into (2)
0.02x + 0.66y = 0.47 × 16
0.02(16 - y) + 0.66y = 7.52
0.32 - 0.02y + 0.66y = 7.52
- 0.02y + 0.66y = 7.52 - 0.32
0.64y = 7.20
y = 7.20/0.64
y = 11.25 liters
Substitute y = 11.25 liters into (1)
x + y = 16
x + 11.25 = 16
x = 16 - 11.25
x = 4.75 liters

Answer: Point A: −12 3
explanation: I hope that helps
The total sum of angles at a point is 360, so basically just minus 360 by 90 and 60, and u get k, which is 210 °
1 and 8 are alternate exterior
Usually bacteria expansion is modeled with exponential function.
Absolute value is not the correct answer since it models linear growth.
Logarithmic is not the correct answer since it has an asymptote in the direction of the x axis.
I will answer to this question "Polynomial" since it is likely to represent bacteria growth.
