Answer:
Answer would be D
Step-by-step explanation:
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
