Velida took out a 5/1 variable-rate mortgage for $150,000. The interest rate
mr_godi [17]

Answer:

Velidas monthly mortgage payment  will be $828.31

Step-by-step explanation:

From the information given:

The cost of mortgage = $150,000

Monthly interest rate = 5.25%/12= 0.0525/12 = 0.004375

Amortization period = (30 × 12) months = 360 months

The monthly mortgage payment can be determined by using the formula:

E = \dfrac{C \times r}{1 - ( 1+ r)^{-n}}

E = \dfrac{150000 \times 0.004375}{1 - ( 1+  0.004375)^{-360}}

E = \dfrac{656.25}{1 - ( 1.004375)^{-360}}

E = \dfrac{656.25}{1 -0.20772}

E = \dfrac{656.25}{0.79228}

E = $828.31

Can you please show me how to do this problem. (I will mark Brainliest)
Kisachek [45]

Answer:

Sin A = 0.6896

Cos A = 0.7241

Tan A = 0.9524

Step-by-step explanation:

Using SOH-CAH-TOA

Sin A = Opposite / Hypotenous

         = 20 / 29

         = 0.6896

Cos A = Adjacent / Hypotenous

          = 21 / 29

         = 0.7241

Tan A = Opposite / Adjacent

          = 20 / 21

          = 0.9524
