X/58 (is roughly) 30
x/58 = 30
Multiply 58 on both sides.
x = 1,740
So it has to be c. 1,843
I assume there are some plus signs that aren't rendering for some reason, so that the plane should be
.
You're minimizing
subject to the constraint
. Note that
and
attain their extrema at the same values of
, so we'll be working with the squared distance to avoid working out some slightly more complicated partial derivatives later.
The Lagrangian is
Take your partial derivatives and set them equal to 0:
Adding the first three equations together yields
and plugging this into the first three equations, you find a critical point at
.
The squared distance is then
, which means the shortest distance must be
.
Answer:Two
Step-by-step explanation:
Given
One coat of waterproofer cover
For two coating of waterproofer area of wooden crate remain same so we need same amount of waterproofer to cover it with second coat
So, we require two can of waterproofer to get double coating
