x = 375 and y = 6300. Option C.
Step-by-step explanation:
From the given data we need to find the value of x and y.
First, we will find out the ratio of area and the force.
=
So,
or, x = = 375
Again,
or, y = 420×15 = 6300
Hence,
x = 375 and y = 6300.
Given:
In ΔKLM, l = 48 inches, ∠K=55° and ∠L=46°.
To find:
The length of k, to the nearest inch.
Solution:
According to Law of sine,
In ΔKLM, using law of sine, we get
On further simplification, we get
Approximate the value to the nearest inch.
Therefore, the length of k is 55 inch.
The Lagrangian is
It has critical points where the first order derivatives vanish:
From the first two equations we get
Then
At these critical points, we have
(maximum)
(minimum)
