It has a 6:1 ratio meaning for every 6 cups of apple juice there is 1 cup of lemon-lime soda
Answer:
A. Length of a bead necklace compared with the number of identical beads
Step-by-step explanation:
Using identical beads in a necklace means that the length of the necklace will depend on the total number of identical beads in the necklace.
For each bead added, the length of the necklace will increase a given, constant, amount. This is a constant rate of change.
184.2 is the answer to 4 significant figure
I assume you're asked to solve
4 cos²(<em>x</em>) - 7 cos(<em>x</em>) + 3 = 0
Factor the left side:
(4 cos(<em>x</em>) - 3) (cos(<em>x</em>) - 1) = 0
Then either
4 cos(<em>x</em>) - 3 = 0 <u>or</u> cos(<em>x</em>) - 1 = 0
cos(<em>x</em>) = 3/4 <u>or</u> cos(<em>x</em>) = 1
From the first case, we get
<em>x</em> = cos⁻¹(3/4) + 2<em>nπ</em> <u>or</u> <em>x</em> = -cos⁻¹(3/4) + 2<em>nπ</em>
and from the second,
<em>x</em> = <em>nπ</em>
where <em>n</em> is any integer.
