Answer:
a ∥ b
Step-by-step explanation:
The symbol "∥" means parallel lines.
Taking a look at the figure above, we have 2 parallel lines, labelled a and b.
A and B are two points on line "a", forming segment AB. However, segment AB is part of line "a".
Same applies to line "b", which has 2 points forming segment CD.
Therefore, the correct label if the parallel lines is a ∥ b

Answer:
The number of bacteria's increases in 5 days will be 1790.
Step-by-step explanation:
The bacterium population is rising day by day, and the function that depicts this growth is Future amount = 100(1+0.9)⁴'⁵.
Now the bacterial growth will be:-
- Future amount = 100 ( 1 + 0.9 )⁴'⁵.
- Future amount = 100 ( 1.9 ) ⁴'⁵.
- Future amount = 1790
Answer: The area of the circle will be less than the area of the square.
Step-by-step explanation:
The area of the square is 7.7² = 59.29 cm²
The area of the circle is calculated by first finding the radius 7.7/2=r= 3.85
A= π 3.85² this is approximately 46.57 cm²
