She needs 750 meters because 1,000 x .75 is 750 i thinkk
1. By the chain rule,
I'm going to switch up the notation to save space, so for example, is shorthand for .
We have
Similarly,
where
To capture all the partial derivatives of , compute its gradient:
2. The problem is asking for and . But is already a function of , so the chain rule isn't needed here. I suspect it's supposed to say "find and " instead.
If that's the case, then
as the hint suggests. We have
Putting everything together, we get

Answer:
g = (h+a) - l
None of them
Step-by-step explanation:
Suppose your car has h liters of engine oil in the morning. During the day, some oil may have leaked, you may have added more oil, or both. The oil level in the evening is g liters. Which of the following expressions always represents how far away the new oil level is from the previous oil level? H+G lGl none of them
Let
h = liters of oil in the morning
l= liters that has leaked
a= liters that were added during the day
g= amount of liters at the end of the evening
Total liters of oil in the evening= (litres of oil in the morning + litres of oil added during the day) - litres of oil that leaked
Substituting each variable into the formula, we have
g = (h+a) - l
