zavuch27 [327]

Answer:

The number of days are independent and the total number of minutes are dependent.

The required model for the situation is $m=25d$

The table is shown below:

Step-by-step explanation:

Consider the provided information.

Joshua spends 25 minutes of each day reading. Let d be the number of days that he reads, and let m represent the total minutes of reading.

We need to determine which variable is independent and which is dependent.

Here, the number of days are independent and the total number of minutes are dependent.

If he spends 25 minutes each day. So the total number of minutes in d days are:

$m=25d$

The required model for the situation is $m=25d$

Now make the table which showing the number of minutes spent reading over 7 days.

Substitute the value of d from 1 to 7 in $m=25d$

Number of days(D) Minutes(M)

A family has a $93,411, 20-year mortgage at 5.4% compounded monthly. Find the monthly payment. Also find the unpaid balance afte

Mademuasel [1]

Answer:

payment: $637.30
5-year balance: $78,505.48
10-year balance: $58,991.59

Step-by-step explanation:

1. The relevant formula for computing the monthly payment A from principal P and interest rate r for loan of t years is ...

A = P(r/12)/(1 -(1 +r/12)^(-12t))

Filling in the numbers and doing the arithmetic, we get ...

A = $93,411(0.054/12)/(1 -(1 +0.054.12)^-(12·20)) ≈ $637.30

2. The relevant formula for computing the remaining balance after n payments of amount p on principal P at interest rate r is ...

A = P(1 +r/12)^n -p((1 +r/12)^n -1)/(r/12)

Filling in the given values and doing the arithmetic, we get ...

A = $93,411(1.0045^60) -637.30(1.0045^60 -1)/(0.0045) ≈ $78,505.48

3. The same formula with n=120 gives ...

A = $93,411(1.0045^120) -637.30(1.0045^120 -1)/(0.0045) ≈ $58,991.59
