Question

When q is directly proportional to (P-1)² and
q=
p=3
find the values of
P when q = 80.
= 20 ,

Answer 1

Answer:

9

Step-by-step explanation:

q∝(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
