Answer:

n = 135 m = 45

Step-by-step explanation:

N is 135 and m is on a strait line (180) so if you do 180 - 135 you will get the answer for m.

Hope this helped.

The difference in salary is 36000-28000=8000

The difference in annual increase is 3000-2000=1000

Therefore it takes 8000/1000= 8 years to catch up.

At the end of eight years,

Salary with the first company = 28000+8*3000=52000

Salary with the second company = 36000+8*2000=52000

Brett has a 30 year fixed rate mortgage for $112500 with monthly payments of $603.92. The annual interest rate is 5% what is the

LUCKY_DIMON [66]

Answer:

a. Total cost of the principal = $217,411.20

b. Interest for the mortgage loan = $104,911.20

Step-by-step explanation:

Total cost of the principal = Monthly payment * Number of years * Number of months in a year = $603.92 * 30 * 12 = $217,411.20

Total cost of the principal of the loan includes the mortgage loan amount and the interest for the mortgage loan. Therefore, the interest for the mortgage loan can be calculated as follows:

Interest for the mortgage loan = Total cost of the principal - Mortgage loan amount = $217,411.20 - $112,500 = $104,911.20

Use the function f(x) = x2 + 6x + 6 and the graph of g(x) to determine the difference between the maximum value of g(x) and the

Bingel [31]

The answer is 15,

because F(X)'s minimum value is (-3, -3)

and G(X)'s maximum value is (12, 3)

So when you subtract -3 from 12, you get a number that is greater then both. (because of the negative 3)

12 - (-3) = 15

What is the perimeter of the figure in the diagram (round to three decimal places if necessary)?

Y_Kistochka [10]

Perimeter (p) = length around a shape.
So any horizontal sides we can add based upon their length in x-values and any vertical sides we can add based upon their length in y-values. The diagonal sides we can find by the distance formula:
$d = \sqrt{( {(x2 - x1)}^{2} + {(y2 - y1)}^{2} }$
So the bottom base goes from x=1 to x=8, then up 1, right 1, and up from y=3 to y=9, then left from x=9 to x=6, down from y=9 to y=6, left from x=6 to x=3.
So far that is: (8-1)+1+1+(9-3)+(9-6)+(9-6)+(6-3)
= 7+2+6+3+3+3 = 24
Now for the diagonal:
$d = \sqrt{( {(x2 - x1)}^{2} + {(y2 - y1)}^{2}) } \\ = \sqrt{( {(3- 1)}^{2} + {(6 - 2)}^{2} )} \\ = \sqrt{( {2}^{2} + {4}^{2} )} = \sqrt{(4 + 16)} \\ = \sqrt{20} = 2 \sqrt{5} = 4.47$
P = 24 + 4.47 = 28.47
D) 28.472
