Answer:
1 1/3 cups of juice
Step-by-step explanation:
Let the volume of the container be c, which is measured in cups.
Then (2/3)c = (8/9) cups juice. We must solve this for the container volume, c.
(8/9) cups
c = ----------------
2/3
Inverting the divisor (2/3) and multiplying, we get:
3(8/9 cups)
c = ------------------ = 12/9 cups, or 4/3 cups, or 1 1/3 cups.

The container originally held 1 1/3 cups of joice.
Cos (a-b) = cos(a)cos(b) + sin(a)sin(b)
cos (a+b) = cos(a)cos(b) - sin(a)sin(b)
so, cos(a-b) - cos(a+b) =
=cos(a)cos(b) + sin(a)sin(b) - [cos(a)cos(b) - sin(a)sin(b)]
=2sin(a)sin(b)
Answer:
y=1/2x-9
Step-by-step explanation:
y=-2x-4
perpendicular slope = opposite reciprocal
y=1/2x+b
-8=1/2*2+b
-8=1+b
b=-9
