Based on the information below, choose the correct answers. note: the monthly loan payment was calculated at 119 payments of $330.38 plus a final payment of $329.73. loan balance: $25,000.00 loan interest rate: 10.0% monthly loan payment: $330.38 number of payments: 120 cumulative payments: $39,644.95 total interest paid: $14,644.95 on average, what dollar amount of each monthly payment is interest? $ what percent of the total payments is total interest? %

Step-by-step explanation:

a) The amount of concern is ...

  (total interest)/(number of payments) = interest/payment

  $14,644.95/120 ≈ $122.04 . . . . amount of interest per payment

__

b) The ratio of concern is ...

  (total interest)/(total payments) × 100% = 14,644.95/39,644.95 × 100%

  ≈ 36.94% . . . . percent of total payments that is interest

the value of v.w= -12.

step-by-step explanation:

we are given three vector r,v and w as:

r = < 5, -5, -2> ; v = < 2, -8, -8> ; w = < -2, 6, -5>

we know that r,v and w could also be represented as:

r=5i-5j-2k

v=2i-8j-8k

and w= -2i+6j-5k

where i,j and k are the unit vectors of x,y and z-axis respectively.

also we know that it has the following property:

i.i=1 ; j.j=1; k.k=1

and i.=j.i=i.k=k.i=j.k=k.j=0

i.e. when we multiply two vectors or we find it's dot product we need to only multiply the components of x coordinates with each other; y with each other and z with each other.

hence, v.w= (2i-8j- -2i+6j-5k)

                  = 2×(-2)+(-8)×(6)+(-8)×(-5)

                  = -4-48+40

                  = -12

hence, v.w= -12
