QUESTION 1 (Income and expenditure)
The Kynsa SPCA is looking for sponsorships to help the many animals left destitute after
the huge fire that raged through the town.
A group of learners decide to sell hamburgers to help raise funds for the SPCA. They expect
sell 500 burgers at the Sunday flea market:
The cost to see a stall is R300. One burger costs R7,00 which includes the burger bun, patty and
garnishing. They hire a gas baai sand at a cost of R150. They plan sell each burger for R18
1.1 Calculate the:
a) fixed cost
b) Variable cost
c) Total cost

​

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: plz put a pic in so i can answer it

step-by-step explanation:

e

step-by-step explanation:

an equation by definition has to have two or more variables (x and 2 in this case)

i am so sorry , i have no idea but i want points so i won't be a beginner anymore
