Answer:

The answer is C. 28.8 in

Step-by-step explanation:

Given a=16 and b=24,

c = 28.84441 = 8√13

∠α = 33.69° = 33°41'24" = 0.588 rad

∠β = 56.31° = 56°18'36" = 0.98279 rad

h = 13.3128

area = 192

perimeter = 68.84441

inradius = 5.57779

circumradius = 14.42221 = 4√13

Answer:

| 10  -10  1  |

|  1    -2  -4 |

| -8  13 -24|

Step-by-step explanation:

First multiply each element in matrix A, this gives:

| -6  - 2  -3 |

|  1   -6   -4 |

| -4   5    0 |

Now we multiply each element in matrix B by  4, this gives:

| -16  8  -4 |

|  0   -4  0  |

|  4  -8  24 |

Finally subtract  this from the first matrix ( subtracting element by element) gives:

| 10  -10  1 |

|  1    -2  -4|

| -8   13- 24|

lawyer [7]

Answer:

First\ monthly\ payment= $858.69

Step-by-step explanation:

From the Question we are told that

Borrows $65,000

Annual interest  8.5%

Monthly repayment over 8 years

Generally PV of annuity with growth is mathematically represented as

where PV is present value

PV of annuity with growth X= (P/ (r-g)) * (1- ((1+g)/(1+r))^n)

     \frac{P}{\frac{8\%}{y12-0.2\%} } *(1-((1+0.2\%)/(1+8.5\%/12))^(^8^*^1^2^)^)=65000

    196.7213115P* 0.384791918=65000

     196.7213115P=65000/0.384791918

    196.7213115P=168922.4668

     P= 168922.4668/196.7213115

    P= 858.6892063

First\ monthly\ payment= $858.69
