The value of d is 27/2 when v =30
<h3>What is equation?</h3>
Equation is the defined as mathematical statements that have a minimum of two terms containing variables or numbers is equal
Suppose that d is directly proportional to the square of v.
So the equation is, d ∝ v² equals to d = kv², where<em> k</em> is a constant.
So in order to find the value of <em>k</em>,
d = <em>k</em> v²
d = 6, v = 20,
Substitue the value of d and v into the equation :
6 = <em>k</em>(20)²
k = 6/400
k = 3/200
Substitue the value of <em>k</em> and v =30 into the equation,
d = 3/200(30)²
d = 2700/200
d = 27/2
Hence, the value of d is 27/2 when v =30

Step-by-step explanation:
15. If A and B are complementary angles, then sin A = cos B and cos A = sin B.
So if sin A = m, then cos B = m.
16. If sin A = cos B, or cos A = sin B, and A and B are acute, then A and B are complementary.
a. cos 60° = sin θ
60° + θ = 90°
θ = 30°
b. sin 71° = cos θ
71° + θ = 90°
θ = 19°
c. sin θ = cos (θ + 20°)
θ + θ + 20° = 90°
2θ = 70°
θ = 35°
d. sin (θ − 60°) = cos θ
θ + θ − 60° = 90°
2θ = 150°
θ = 75°
