Answer:
5
Step-by-step explanation:
SQ= 10
SO is half way so divide by 2
Answer: a) 800
b)
Step-by-step explanation:
The exponential growth function is represented by :-
, where A is initial value , b is the multiplicative rate of change and t is the time period.
Given : A bacteria culture starts with 100 bacteria and doubles in size every half hour.
i.e. A = 100 and b=2
Then, the exponential growth function to find the number of bacteris after t hours :_
At x=3
Hence, the there are 800 bacteria after 3 hours.
Answer:
3 3/20 or 63/20
Step-by-step explanation:
Answer:
a) 30cm²
b) 8.75cm²
c) 30cm²
Step-by-step explanation:
a) Area of a triangle = 1/2 × base × perpendicular height
= 1/2 × 12 × 5
= 30cm²
b) Area of a triangle = 1/2 × base × perpendicular height
= 1/2 × 3.5 × 5
= 8.75cm²
c) Area of a triangle = 1/2 × base × perpendicular height
= 1/2 × 5 × 12
= 30cm²
