thrice a number =3x
minus z²
HOPE THIS HELPS!!!
1/100 of a pound.
since 1000/100=10, you must do 1/100 to get the weight of 10 samples.
Answer with Step-by-step explanation:
We are given that

Let g(x,y)=
We have to find the extreme values of the given function


Using Lagrange multipliers



Possible value x=0 or 
If x=0 then substitute the value in g(x,y)
Then, we get 


If
and substitute in the equation
Then , we get possible value of y=0
When y=0 substitute in g(x,y) then we get

Hence, function has possible extreme values at points (0,1),(0,-1), (1,0) and (-1,0).




Therefore, the maximum value of f on the circle
is
and minimum value of 
Answer:
C. $2.54/gallon
Step-by-step explanation:
To find the unit price, we take the dollar amount and divide by the number of gallons
$46.74/18.4
2.540217391
The unit price per gallon of gasoline is
$2.54/ gallon

Let's solve the given equation ~








Hence, we get -6 and 1 as our roots ~
So, the correct choices are : B and D
