Answer:

a = 8.5t

y = 32.55

Step-by-step explanation:

Solving (9): The equation of the table

We start by calculating the slope (m)

m = \frac{a_2 - a_1}{t_2 - t_1}

Where:

(t_1,a_1) = (15,127.5)

(t_2,a_2) = (16.5,140.25)

m = \frac{140.25 - 127.5}{16.5 - 15}

m = \frac{12.75}{1.5}

m = 8.5

The equation is then calculated using:

a = m(t - t_2) + a_2

So, we have:

a = 8.5(t - 16.5) + 140.25

Open bracket

a = 8.5t - 140.25 + 140.25

a = 8.5t

Solving (10):

4.8y = 156.24

Required

Find x

Divide both sides by 4.8

y = 32.55

Clark and Lana take a 30-year home mortgage of $128,000 at 7.8%, compounded monthly. They make their regular monthly payments fo
svp [43]

Answer:

Step-by-step explanation:

From the given information:

The present value of the house = 128000

interest rate compounded monthly r = 7.8% = 0.078

number of months in a year n= 12

duration of time t = 30 years

To find their regular monthly payment, we have:

PV = P \begin {bmatrix}  \dfrac{1 - (1 + \dfrac{r}{n})^{-nt}}{\dfrac{r}{n}}    \end {bmatrix}

128000 = P \begin {bmatrix}  \dfrac{1 - (1 + \dfrac{0.078}{12})^{- 12*30}}{\dfrac{0.078}{12}}    \end {bmatrix}

128000 = 138.914 P

P = 128000/138.914

P = $921.433

∴ Their regular monthly payment P = $921.433

To find the unpaid balance when they begin paying the $1400.

when they begin the payment ,

t = 30 year - 5years

t= 25 years

PV= 921.433 \begin {bmatrix}  \dfrac{1 - (1 - \dfrac{0.078}{12})^{25*30}}{\dfrac{0.078}{12}}    \end {bmatrix}

PV = $121718.2714

C) In order to estimate how many payments of $1400  it will take to pay off the loan, we have:

121718.2714 =  \begin {bmatrix}  \dfrac{1300  (1 - \dfrac{12.078}{12}))^{-nt}}{\dfrac{0.078}{12}}    \end {bmatrix}

121718.2714 = 200000  \begin {bmatrix}  (1 - \dfrac{12.078}{12}))^{-nt}   \end {bmatrix}

\dfrac{121718.2714}{200000 } =  \begin {bmatrix}  (1 - \dfrac{12.078}{12}))^{-nt}   \end {bmatrix}

0.60859 =  \begin {bmatrix}  (1 - \dfrac{12}{12.078}))^{nt}   \end {bmatrix}

0.60859 = (0.006458)^{nt}

nt = \dfrac{0.60859}{0.006458}

nt = 94.238 payments is required to pay off the loan.

How much interest will they save by paying the loan using the number of payments from part (c)?

The total amount of interest payed on $921.433 = 921.433 × 30(12) years

= 331715.88

The total amount paid using 921.433 and 1300 = (921.433 × 60 )+( 1300 + 94.238)

= 177795.38

The amount of interest saved = 331715.88  - 177795.38

The amount of interest saved = $153920.5

If nx10^p is a positive number written in scientific notation which statements must be true? Select all that apply
liq [111]

For this case we have the following number written in scientific notation:


n * 10 ^ p

We know that this number is greater than zero because it is a positive number.

Therefore, the following statements are true:

p ∈ (-∞, ∞)

n must be between 1 and 10

n ∈ [1, 10]

Answer:

The following statements are correct about the number written in scientific notation:

p ∈ (-∞, ∞)
