Answer:
p = 16
Step-by-step explanation:
Given p is directly proportional to (q + 2)² then the equation relating them is
p = k(q + 2)² ← k is the constant of proportion
To find k use the condition when q = 1, p = 1
1 = k(1 + 2)² = k × 3² = 9k ( divide both sides by 9 )
= k
p = (q + 2)² ← equation of proportion
When q = 10 , then
p = × (10 + 2)² =
× 12² =
× 144 = 16
