Question : 8 of 40

Marks: +1, -0

Q and R are related as per the given equation:

Q = k * R^2

. It is given that if Q = 2 and R = 2. What is the value of Q, when R = 4?

Solution:

The given equation

= Q = k * R^2

where, Q = 2 and R = 2.
Value of

k = k*(2)^2

2/4=k⇒1/2

Now

Q=K*R^2

K=1/2,R=4

Q=1/2×(4)^2=1/2×16=8

Q=8
