Question

Write the sum of intercepts cut off by the plane r.(2i+j-k)-2=0 on the three axes

Answer 1

You are given some denominations of coins in an array (int denom[])and infinite supply of all of them. Given an amount (int amount), find the minimum number of coins required to get the exact amount. What is the method called?

Answer 2

Step-by-step explanation:

Put r vector = xi^ + yj^ + zk^

2x+y-z=2

x/1 + y/2 + z/-2 = 1

a= 1, b = 2, c = - 2

SUM of intercepts = 1+2-2 = 1
