A seat’s position on a Ferris wheel can be modelled by the function () = (. + . ) + .
where ℎ() represents the height in metres and represents the time in minutes. What is the height of
the seat, to the nearest tenth of a metre, after 1.5 min?

found it xd it ok yt

6 spoons of sugar for every 21 cups of flour

step-by-step explanation:

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

you have to find the same variables -3n - 5n so this would be -3n +(-5n) which equals -9n
