anna is buying a house selling for 185,000. to obtain the mortgage, anna is required to make a 20% down payment. anna obtains a
JulsSmile [24]

Answer:

a. The Amount of the required down payment is $37,000

b. The amount of the mortgage is $148,000

c. The monthly payment for principal and interest is $953.62 per month

Step-by-step explanation:

a) In order to calculate the Amount of the required down payment  we would have to use the following formula:

Amount of down payment = Value of home x Required down payment percentage

= $185,000 x 20%

= $37,000

b)  In order to calculate the Amount of the mortgage we would have to use the following formula:

Amount of the mortgage = Value of home – Down payment

= $185,000 - $37,000

= $148,000

c)  Loan Amount (P) = $148,000

Monthly Interest Rate (n) = 0.5% per month [6.00% / 12 Months]

Number of months (n) = 300 Months [25 Years x 12 Months]

Therefore, the Monthly Loan Payment = [P x {r (1 + r)n} ] / [(1 + r)n – 1]

= [$148,000 x {0.005 x (1 + 0.005)∧300}] / [(1 + 0.005)∧300 – 1]

= [$148,000 x {0.005 x 4.464}] / [4.464 – 1]

= [$148,000 x 0.02232] / 3.464

= $3,303.36 / 3.464

= $953.62 per month

The monthly payment for principal and interest is $953.62 per month

Given that secant theta = Negative StartFraction 37 Over 12 EndFraction, what is the value of cotangent theta, for StartFraction
Iteru [2.4K]

cot\theta  =\frac{12}{35}

Step-by-step explanation:

sec\theta =\frac{37}{12}

⇔\frac{1}{cos \theta} =\frac{37}{12}

⇔cos \theta = \frac{12}{37}

we know that

sin \theta = \sqrt{1-cos^2\theta}

sin\theta =\sqrt{1-(\frac{12}{37})^2 }

sin\theta=\sqrt{\frac{1225}{1369} }

sin\theta = \frac{35}{37}

Therefore cot\theta =\frac{cos\theta}{sin\theta}  =\frac{\frac{12}{37} }{\frac{35}{37} }  =\frac{12}{35}  , for \frac{\pi}{2}
