Answer:

loan: $157,823
repaid: $378,000
interest: $220,177

Step-by-step explanation:

For a loan value of 1, the monthly payment on a 30 year loan at 7% is ...

A = (0.07/12)/(1 -(1 +0.07/12)^(-12·30)) ≈ 0.00665302495

Then the amount repaid after 360 payments is ...

360A = 2.39508898 . . . times the principal amount

a) For a monthly payment of $1050, the principal can be ...

$1050/0.00665302495 ≈ $157,823

b) The amount repaid to the loan company is ...

$157,823×2.39508898 ≈ $378,000

c) The amount that is interest is ...

$378,000 -157,823 = $220,177

Answer:

y = -2x + 12

Step-by-step explanation:

Step 1: find the slope

y = 1/2x + 5

The equation of the line is

y = mx + c

m - slope

m = 1/2

Note : if two lines are perpendicular to the other, both lines are negative reciprocal of each other

m = -2

Step 2 : using a point slope form

y - y1 = m( x - x1)

( 2 , 5)

x1 = 2

y1 = 5

y - 2 = -2( x - 5)

y - 2 = -2x + 10

y = -2x + 10 + 2

y = -2x + 12

The equation of the line is

y = -2x + 12

Given a polynomial p(x)=0, which two expressions could be a pair of irrational roots of the equation square root 2-3, 2-square r

sasho [114]

Answer:

2-square root 3, 2+ square root 3

Step-by-step explanation:

If the polynomial has rational and real coefficients, the roots will be "conjugates" of each other. That is, the sum of the root should be a rational number. So, the irrational parts will be opposites, while the rational parts remain the same.

2±√3 . . . can be the roots of p(x) when p(x) has rational real coefficients

Shawn owns The Muffin mobile food truck. He goes home after he sells more than 200 muffins. He began the day with a big 36 muffi

lys-0071 [83]

Answer:

Step-by-step explanation:

he sold 36 so lets subtract that from the 200 so he has to sell 164 more.

Now we have to figure out what times 24 is 164

It is about 7 because 24 x 7 = 28 and if he needs to sell mORE THAN it can't be 6 so it is 7 hours.

If the points A(2,a) and B(5,8) determine a line with a slope 2/3, find the value of a.

icang [17]

Answer:

(2,1) and "a" will be 1.

Step-by-step explanation: When you plot point B in a grid, use the slope to go up and down then find a place when x is 2. Then find the y and then you;ll have the answer.
