Answer:

14.4222

Step-by-step explanation:

Distance between two points = √(x₂ – x₁)² + (y₂ – y₁)²

Distance between two points = √(6 – -2)² + (-5 – 7)²

√(6 – -2)² + (-5 – 7)²

√8² + (-12)²

√64 + 144

√208

Answer:

4\sqrt{13}

Step-by-step explanation:

Calculate the distance d using the distance formula

d = \sqrt{(x_{2}-x_{1 )^2+(y_{2}-y_{1})^2   }

with (x₁, y₁ ) = (- 2, 7) and (x₂, y₂ ) = (6, - 5)

d = \sqrt{(6-(-2))^2+(-5-7)^2}

   = \sqrt{6+2)^2+(-12)^2}

   = \sqrt{8^2+144}

   = \sqrt{64+144}

   = \sqrt{208}

   = \sqrt{16(13)}

   = 4\sqrt{13}

If Mary pay $3695.20for principal and interest every month for 30 years on her $110,000 loan, how much interest will she pay ove
PilotLPTM [1.2K]

Answer:

  $1,220,200

Step-by-step explanation:

The total of Mary's payments is ...

  $3695.20/mo × 30 yr × 12 mo/yr = $1,330,200

The difference between this repayment amount and the value of her loan is the interest she pays:

  $1,330,200 -110,000 = $1,220,200 . . . total interest paid

_____

Mary's effective interest rate is about 40.31% per year--exorbitant by any standard.

WILL GIVE BRANLIEST!!! Pls help! Determine the coordinates of the point on the straight line y=3x+1 that is equidistant from the
iren [92.7K]

Let , coordinate of points are P( h,k ).

Also , k = 3h + 1

Distance of P from origin :

d=\sqrt{h^2+k^2}

Distance of P from ( -3, 4 ) :

d=\sqrt{(h+3)^2+(k-4)^2}

Now , these distance are equal :

h^2+(3h+1)^2=(h+3)^2+(3h+1-4)^2\\\\h^2+(3h+1)^2=(h+3)^2+(3h-3)^2

Solving above equation , we get :

P=(\dfrac{16}{21},\dfrac{23}{7})

Hence , this is the required solution.
