Answer:

La elevación de la carretera es de aproximadamente 0.999 metros.

Step-by-step explanation:

Cuando se dice que la pendiente es de 5 %, se quiere decir que la tangente del ángulo de elevación de la carretera es de 0.05. Trigonométricamente hablando, podemos calcular el ángulo de la pendiente como sigue:

\theta = \tan^{-1} 0.05

\theta \approx 2.862^{\circ}

La elevación de la carretera se determina mediante la función seno:

\sin \theta = \frac{h}{l} (1)

Donde:

h - Elevación de la carretera, medida en metros.

l - Longitud de la carretera, medida en metros.

Si sabemos que l = 20\,m y \theta \approx 2.862^{\circ}, entonces la elevación de la carretera es:

h = l\cdot \sin \theta

h \approx 0.999\,m

La elevación de la carretera es de aproximadamente 0.999 metros.

BlackZzzverrR [31]

Answer:

Size of each monthly payment = $161.69 per month

Step-by-step explanation:

Given:

Value of property = $20,000

Downpayment = 20%

Number of payment = 12 x 10 = 120

Interest rate = 4% = 4% / 12 = 0.33 %

Computation:

Loan balance = 20,000 - 20%

Loan balance = $16,000

A] Size of each monthly payment [In Excel]

Size of each monthly payment = PMT(0.33%,120,16000,0)

Size of each monthly payment = $161.69 per month
