Answer: <em>Weight(lbf) = 4830</em>
Step-by-step explanation:
Given :
Mass of the roommate = 150 lbm
Since we know that g =
Therefore, we can calculate his/her weight in lbf using the following formula:
Weight(lbf) = Mass × g
Weight(lbf) = 150 × 32.2
<em>Weight(lbf) = 4830</em>
Answer:
yes
Step-by-step explanation:
Hello,
f(x,y)=2(x²+y²)-25(x²-y²)=0(1)
@f/@x=2*2*(x²+y²)*2x-50x
@f/@y=2*2*(x²+y²)*2y-50y
dy/dx=-(@f/@x)/(@f/@y)=0
==> 2x*(4x²+4y²-25)=0
==>x=0 or x²+y²=25/4 (2)
As (1)==>2*25/4-25(x²-y²)=0
==> x²-y²=1/2 (3)
(2) and (3)=>2x²=27/4 ==>x²=27/8 and y²=23/8
==>x=-√(27/8) and (y=-√(23/8) or y=+√(23/8)
or x=√(27/8) and (y=-√(23/8) or y=+√(23/8)
