Enrico deposited $2000, in a savings account. Each month he will deposit an additional $25. Which kind of function best models t

AfilCa [17]

Answer:

<em> Linear model </em>

The function f(x) which represents the total amount in the savings account in x months is given by: f(x)=25x+2000

Step-by-step explanation:

Given:

Enrico deposited $2000 in a savings account.

Each month he will deposit additional $25.

This shows that the rate at which the amount is increasing each month is constant.

Therefore, the model will be linear with a slope 25.

So , if x represents the number of months.

and f(x) represents the corresponding amount in the account.

Then the function f(x) is given by: f(x)=25x+2000

What is 168.023 in expanded form using fractions

bonufazy [111]

Answer:

The expanded form of 168.023 is 100 + 60 + 8 + $\frac{2}{100}$ + $\frac{3}{1000}$

Step-by-step explanation:

Expanded form:

Is a way to write numbers to see the math value of the digits.

When numbers are separated into their place values and decimal places they can also form a mathematical expression.

Ex: 5,325.27 in expanded form is 5,000 + 300 + 20 + 5 + $\frac{2}{10}$ + $\frac{7}{100}$ = 5,325.27

Let us solve the question

∵ The number is 168.023

∵ Its hundreds digit is 1

∴ Its value = 100

∵ Its tens digit is 6

∴ Its value = 60

∵ Its units digit is 8

∴ Its value = 8

∵ Its tenths digit is 0

∴ Its value = 0

∵ Its hundredths digit is 2

∴ Its value = $\frac{2}{100}$

∵ Its thousandths digit is 3

∴ Its value = $\frac{3}{1000}$

∴ The expanded form of 168.023 = 100 + 60 + 8 + $\frac{2}{100}$ + $\frac{3}{1000}$
