maybe u had to multiply the rate and monthly payment
A square can be a rectangle but a rectangle can't be a square so seperate rectangles from triangles. since squares are special types of rectangles, they can go in the box of rectangles
Answer:
20 degress i think
Step-by-step explanation:
Answer:
30%
Step-by-step explanation:
150-105 = 45
(45 / 150 ) * 100 = 30%
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)
