She needs 700 milliliters more. 700 ml is 0.7 liters
Answer:
15c+3b=66 and 25c+5b=110
Step-by-step explanation:
A D B C The lowest power is the lowest number. If the powers are the same, the initial number dictates wether it is smaller or larger.
1.Do you think a similar rule is true for cosine? That is, does -cos (θ) = cos (-θ)? Pick a value of θ and test this theory.
It is not the same.
To prove it, let's choose a value of the angle:
θ = 45 degrees:
-cos (θ) = cos (-θ)
-cos (45) = cos (-45)
- (root (2) / 2) = (root (2) / 2)
answer:
NOT fulfilled: -cos (θ) = cos (-θ) (false)
2. Using your example above, speculate on a rule that might be true for cos (-θ).
cos (θ) = cos (-θ)
To prove it, let's choose a value of the angle:
θ = 45 degrees:
cos (θ) = cos (-θ)
cos (45) = cos (-45)
(root (2) / 2) = (root (2) / 2)
answer
A rule for cosine can be:
cos (θ) = cos (-θ)
Answer:
b. -6

I recommend using a calculator. symbolab calculator is a really good one. it tells you how to solve and gives the answer.
