2 answers:
Solution:
we have been asked to find the sum of the even integers between 21 and 45.
The even integers between 21 and 45 is
22, 24, 26,28, 30, 32, 34, 36,38, 40, 42,44.
its forming an arithmetic progression with
first term=22=a
number of term=12=n
common difference=24-22=2=d
The sum can be found using the formula
Substitute the values in the above formula we get

Answer: a)
b) 25165824000
Step-by-step explanation:
The exponential equation for growth is given by :-
, where a= initial value , b =multiplicative growth factor and t = time.
Given : A bacteria culture contains 1500 bacteria initially and doubles every hour.
i.e. a = 1500 and b= 2
Then, the function N that models the number of bacteria after t hours will be :
To find , the number of bacteria after 24 hours , we put t= 24 in above equation , we get
Hence, the number of bacteria after 24 hours is 25165824000.
