Answer:
A) 21.02°
B) 26.74°
C) 22.79°
D) DNE
Step-by-step explanation:
We can solve the equation for the angle:
D = 672·sin(2θ)
D/672 = sin(2θ)
arcsin(D/672) = 2θ
θ = arcsin(D/672)/2
A) For D = 450, θ = arcsin(450/672)/2 = 21.0198° ≈ 21.02°
B) For D = 540, θ = arcsin(540/672)/2 = 26.7363° ≈ 26.74°
C) For D = 480, θ = arcsin(480/672)/2 = 22.7923° ≈ 22.79°
D) For D = 720, θ = arcsin(720/672)/2 = DNE
Answer:
Please check the explanation.
Step-by-step explanation:
'3 meals a day' is a unit rate because there is a 1 in the denominator.
A unit ratio is a fraction between two dissimilar units with a denominator 1.
'3 meals a day' indicate that someone is eating 3 meals in one day.
i.e. unit rate = 3 meals / per day
Therefore, we conclude that '3 meals a day' is a unit rate because there is a 1 in the denominator.
The unchanging value of the ratio between the two proportional quantities is called a constant of proportionality.
For example,
we know that the equation
where is the constant of proportionality and '
' and '
' are two proportional quantities, directly proportional to each other.
Thus, The unchanging value of the ratio between two proportional quantities is called the constant of proportionality.
