Question 983331: The component of v = 260i + 300j represent the respective number of gallons of a regular and
premium gas sold at a gas station. The components of w = 2.50i +2.65j represent the respective
price per gallon for each kind of gas. Find the dot product V * W and describe what the answer
means in practical terms.
Answer by Timnewman(323)   (Show Source):
You can put this solution on YOUR website! Hi,
Please, note that * means dot
V*w=(260i+300j)*(2.50i+2.65j)
multiply term by term,
V*w=650+795
V*w=1445
In pratical term,the number of gallon V of the gas sold is a fuction of the price W of the gas.
The answer reveals that if the component price of a gallon of a gas increase,the number of the gas decrease. Hope this helps;
