Q is directly proportional to √p Q = 21 when p = 9, the value of Q when p = 81 is * 1 point
63
64
56
67

We get Q=63 when p=81

Option A is correct.

Step-by-step explanation:

We are given that

We can write it as

Where k is constant of proportionality.

We are given Q = 21 when p = 9

Using this Q = 21 when p = 9 we can find value of k

So, we get constant of proportionality k = 7

Now, Finding the value of Q when p = 81

We are given p=81, k=7, we need to find Q

Using the equation we can find value of Q.

So, we get Q=63 when p=81

Option A is correct.
