There are 2 years left until desmond attends college. he wants to go full time for 4 years to a college that costs $25,000 a year. his parents' goal is to save enough to pay 75% of the cost. there is currently $63,000 in an account they set up. assume that college costs do not increase each year.

75000 is what his parents need to pay to equal 75%

Step-by-step explanation:

the first thing u do it is multipy 25000 x 4 =100000 so then u subtract 25000 from 100000 which equals 75000 and then u subtract 75000

                                                                                                           -63000

                                                                                                             12000

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

answer: yes i agree that you should not put it on/p>

step-by-step explanation: the reason for this is that it wastes other peoples time and also make them fail as well and that is never good.
