Lights are spaced from the hanging light, 4 feet away in the x-direction and 4 feet in the y-direction. select the possible coordinates of the anchors for two other lights. (hint: use the form (x, y, z) for coordinates.)
a. (3, 12, 10) and (11, 12, 10)
b. (7, 8, 10) and (7, 16, 10)
c. (3, 8, 6) and (11, 16, 14)
d. (3, 8, 10) and (11, 16, 10)

a 4/6 = 9/12   not proportional

step-by-step explanation:

to find which are not proportional, we can use cross products

if it is true, they are proportional.   if it is not true, they are not proportional.

a 4/6 = 9/12

4* 12 = 6*9

48 = 54

not this is not proportional  

b 2/3 = 12/18  

2* 18 = 3 * 12

36 = 36

this is proportional

c 5/4 = 10/8  

5*8 = 4*10

40 = 40

this is proportional

d 7/5 = 35/25

7*25 = 5 * 35

175 = 175

is proportional

his first public project he is asked to create a small scale drawing. the garden is a right triangle with base 25m and height 30m. are you trying to solve for the last side/hypotenuse? the irrational form of the answer would be 5\sqrt{61}
