1.if the centroid of a triangle abc is the origin, point b and c are respectively ( 0,6,0 ) and ( 0,0,6 ) then the point a is a. ( 0,-6,0) b. ( 0,0,-6) c. ( 0,6,6,) d. ( 0,-6,-6)
2. the ratio in which the line joining the points ( a, b,c ) and ( -a,-c,-b ) is divided by the xy plane is :
a. a: b
b. b: c
c. c: a
d. c: b

$2416.6

step-by-step explanation:

per hour = $ 25

total work time = 35

commission = 15%

total she has to make = $ 4,500

let she sold x dollar products

so her commission will be 15 % of x

now

total = weekly basic pay + commission

4500= (25*35) + 15 % of x

4500=875 + * x

4500-875 =   * x

3625= * x

multiplying wwith 100 on both sides gives

36250 = 15 x

now

x =  

x= $2416.6

2

step-by-step explanation:

since we know that the two functions are equal, f (x) = g

(x), therefore when we equate the two equations the result should be similar to

3x = x – 4:

a. f(x) = 3x, g(x) = x – 4

equating the two functions:

3x = x – 4             (correct)

so we now got our answer (a)

the answer is

d.
