Question

Naman deposited rupees 4000 in a bank at a rate of 5% p. a. draw a linear graph to show the relationship between time and amount for first 4 years

please tell me in detail with graph (picture) please​

Answer 1

The graph is attached below.

Step-by-step explanation:

Since, for an investment the amount formula ( when there is a linear relation between time and amount ) is,

Where,

P = investment,

t = number of periods,

r = rate per period,

Here, P = 4000, r = 5%,

Thus, the amount after t years,

Hence, the required relation would be,

Graphing : Consider in the coordinate plane x represents time t and y represents amount A corresponding t,

For

For

i.e. join (0, 4000) and (1, 4200) in the coordinate plane.

Also, for t years

Time can't negative ⇒

By the above information we can plot the graph ( that shown below )
