I'm really struggling to figure out the horizontal shift on this assignment. All of my other values are correct but my horizontal shift just isn't coming out right. I was assuming the horizontal shift of the cos function would be -pi/12 while the sin would be -pi/24, but when I plug these numbers into their respective functions, the horizontal shift says 1/2. Can someone just check my work? I only have 260 points but I'm willing to give all of them.

the answer is c

hope this !

step-by-step explanation:

the shape,the size and the distance

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
