Question

6. If q is directly proportional to (p -4 )2 and q = 20
when p = 3, find the values of p when q = 80.

Answer 1

Answer:9

Step-by-step explanation:

qa(p-1)(2)

q=20 when p=3

20=k(3-1)(2)

k= proportionality constant

20=4K

20/4=k

k=5

q=80

p=?

80=k(p-1)(2)

80-5(p-1)(2)

80=10(p-1)

80/10-p-1

8-p-1

p=8+1

p=9
