If A is partly constant and partly varies as P. When A=15 when P=21 and when A=21,P=24 I. Find the law of variation between A and P
I. A when P =33.
To find the law of variation between A and P, we can use the formula A = kP, where k is the constant of variation.
First, we can find the value of k by using the given information. When A = 15 and P = 21, we have:
15 = k * 21
Solving for k, we find:
k = 15/21 = 5/7
Now we can use this value of k to find the value of A when P = 33:
A = (5/7) * 33
A = 165/7
Therefore, A = 23.57 when P = 33.
