9 yards trellis are installed altogether.
Step-by-step explanation:
Given that,
Total Section = 12
Length of each section = yards
Total length of trellis = ?
If we have to find the total length of "n" different section. We have to multiply the "n" with length of individual section "l". Therefore,
Total length of trellis = Length of each section x Total Section
Total length of trellis =
Total length of trellis = 9 yards
Therefore, 9 yards trellis are installed altogether.
Keywords: total length, length of each section

Answer:
1 : 30
Step-by-step explanation:
4 seconds : 2 min
however we know that 1 min has 60 seconds. Hence 2 min will have 2 x 60 = 120 seconds
Therefore we can substitute 2 min with 120 seconds
4 seconds : 2 min
4 seconds : 120 seconds (simplify by dividing both sides by 4)
4/4 : 120/4
1 : 30
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
