Help me with this please

y = 2 units

Step-by-step explanation:

We can solve this in 2 ways, both ways would give the same

#1) Sin(45) =

=> Sin(45) * y =

=> y =

=> y = 2

#2) Cos(45) =

=> Cos(45) * y =

=> y =

=> y = 2

Hope this helps!

1.4

2.3

step-by-step explanation:

the formula for the constant of variation is

y= kx

divide each side by x

y/x =kx/x

y/x =k

we know a and y

1.   y/x = k

4/1 =4

check the other values to make sure they are the same

8/2 = 4   12/3 =4   and 16/4 =4  

the constant of variation is 4

2.   y/x = k

3/1 =3

check the other values to make sure they are the same

6/2 = 3   9/3 =3   and 12/4 =3  

the constant of variation is 3
