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.

a. turk and mcalister

b. howard, mission, and market

c. yes. since streets end some do not cross yet are not parallel to others. example: mcalister and 5th

step-by-step explanation:

parallel lines are lines which do not intersect ever and look a lot like railroad tracks. turk, mcalister and golden gate are examples of these.

intersect are streets which cross each other and a car on one can reach the other. howard, mission, and market intersect with 6th.

skew lines are lines which neither intersect nor are parallel. these lines exist here because some streets end and never intersect another like mcalister and 5th.
