Jake is buying a piece of recycled art from luna he started by paying her $50 and promised to pay $5 a week until he pays the total price what equation shows the relationship between the total amount paid and the number of weeks jake will take to pay luna

The answer is 50 + 5w

Step-by-step explanation: If Jake paid Luna the beggining of the total, that means he dosen't need to pay her that 50 dollars but now he only needs to pay her $5 a week to pay the total price. (also Jake is rich)

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
