The amount of money in an account may increase due to rising stock prices and decrease due to falling stock prices. Marco is stu
Mashcka [7]

The account that recorded a greater percentage change in amount of money over the previous year is year 4

<h3>Part A: Is the amount of money in account A increasing or decreasing?</h3>

The exponential function is given as:

f(x) = 9628 * (0.92)^x

An exponential function is represented as:

f(x) = ab^x

If b is less than 0, then the function is an increasing function.

So, the function f(x) = 9628 * (0.92)^x is a decreasing function.

The percentage of decrement is then calculated as:

r =1 - b

This gives

r = 1 - 0.92

Evaluate

r = 0.08

Express as percentage

r = 8%

Hence, the percentage of decrement is 8%

<h3>Part B: The account that recorded a greater percentage change in amount of money over the previous year</h3>

r  1 2 3 4

g(r) 8,972 8,074.80 7,267.32 6,540.59

As a general rule:

As the number of years increases, the percentage change increases

Hence, the account that recorded a greater percentage change in amount of money over the previous year is year 4

What is the solution? pls help
loris [4]

Answer:

Solve by substitution

[y=5/2x-4]

[y= -x+3]

Substitute y = -x +3

[-x+3=5/2x-4]

Isolate x for -x+3=5/2x-4: x=2

For y = -x+3

Substitute x = 2

y= -2+3

Simplify

y=1

The solutions to the system of equations are:

y=1 x=2

The values that completes the table are 28, 9, 33, 32 and -3

<h3>Tables and values.</h3>

Tables are used to represents the dependent and independent variable of a function. They are used to formulate function.

From the given table, we are to think of any dependent value and subtract 3 from it to get the equivalent independent value.

From the third column;

a3-3 = 25

a3 = 25 + 3

a3 = 28

For the fourth column

a4 = 12 - 3

a4 = 9

For the fifth column

a5-3 = 30

a5 = 30 + 3

a5 = 33

For the sixth column

a6-3 = 29

a6 = 29 + 3

a6 = 32

For the seventh column

0-3 = a7a

a7 =  0 - 3

a7 = -3

Hence the values that completes the table are 28, 9, 33, 32 and -3
