Answer:
4000 rupees
Step-by-step explanation:
20000×10×2/100
= 4000 rupees
In an Arithmetic sequence, each term is obtained by adding the common difference in the previous term as shown in the recursive formula.
The common difference of the sequence is -13. This means, if we -13 to a term we'll obtain the next term.
If a term is 13, the term that will be next to 13 can be obtained by adding -13 to it.
So,
13 + ( -13) = 13 - 13 = 0
Thus, the next term will be 0.
B) 1.6^4 1.6 is being multiplied 4 times
Answer:
A(t) = π(8t)²
Step-by-step explanation:
Radius of a circular wave increases by 8 cm each second.
Every second radius of circular wave so the sequence of increase in radius will be,
8, 16, 24, 32.........(8t)
Here 't' = time
Since, area of a circle = πr²
Therefore, area of the circular wave after 't' seconds since the wave begins,
A(t) = π(8t)²
