⇒ CI=A−P
⇒ Rs.29,775.40−Rs.25,000
∴ CompoundInterest=Rs.4775.40.
17=5k-2
add 2 to both sides
19=5k
divide both sides by 5
19/5=k
19/5=3 and 4/5
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.
Step-by-step explanation:
A rational number is any number that can be divided (written as a fraction) by.
Examples: 1/2, 3, 5/9
*Irrational numbers: cannot be divided
Examples: π, 3.53465374765768957965...
Answer:
2400=2w*w
The length is equal to 2 times the width and you have to multiply the length by the width to get the area.
