Chapter 7: Q. 315E (page 719)

If pvaries directly as qand p=9.6, when q=3. Find the equation that relates pand q.

Short Answer

Expert verified

The equation relating pand qis p=3.2q.

Step by step solution

01

Step 1. Given information

Given that pvaries directly as qand p=9.6when q=3.

02

Step 2. Determine the equation relating p and q.

As pvaries directly as qso, for some constant k, p=kq.

Label the obtained equation.

localid="1645345133597" p=kq1

Substitute the given values and solve for k.

localid="1645345034732" 9.6=k路39.63=k3.2=k

Substitute 3.2for kinto equation 1.

localid="1645345177659" p=3.2q
