Question in Hindi

एक पार्क चतुर्भुज ABCD के आकार का है, जिसमें ZC = 90", AB = 9 मी., BC = 12 मी., CD = 5 मी. तथा AD = 8 मी. है। इस पार्क का कितना क्षेत्रफल है?

​

Answer 1

Account A: Decreasing at 8 % per year

Account B: Decreasing at 10.00 % per year

The amount f(x), in dollars, in account A after x years is represented by the function below:

f(x) = 10,125(1.83)x

Account B shows the greater percentage

change

Step-by-step explanation:

Part A: Percent change from exponential

formula

f(x) = 9628(0.92)*

The general formula for an exponential

function is

y = ab^x, where

b = the base of the exponential function.

if b < 1, we have an exponential decay

function.

f(x) decreases as x increases.

Account A is decreasing each year.

We can rewrite the formula for an

exponential decay function as:

y= a(1 – b)”, where

1- b = the decay factor

b = the percent change in decimal
