Answer:
3 7/9
Step-by-step explanation:
4/5 recommend, so about 4/5(120) = 96 doctors recommend the brand.
A and B because if you look on a meter stick
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:
<u>1.14 m²</u>
Step-by-step explanation:
- Area (shaded) = Area (quarter circle) - Area (triangle)
- Area (shaded) = πr²/4 - 1/2r²
- Area (shaded) = 3.14 x 4 / 4 - 1/2 x 4
- Area (shaded) = 3.14 - 2
- Area (shaded) = <u>1.14 m²</u>
