Let
x--------> the time in minutes
y-------> an altitude in feet
we know that
For x=0 min y=0 ft
For x=50 min y=52,000 ft
so
the rate of change is equal to calculate the slope of the linear equation
Round to the nearest hundred-------->
therefore
<u>the answer is</u>
Solution:- Given that the total revenue function
,where x is the number of rooms filled
Now, differentiating the function w.r.t. x,we get
To find critical points ,Put
Given:
The system of equations that represent the constraints for the given situation is
To find:
The solution of given system of equations.
Solution:
We have,
...(i)
...(ii)
Multiply equation (i) by 4.
...(iii)
Subtracting (iii) from (ii), we get
Divide both sides by 12.90.
Put this value in (i).
The solution of system of equations is x=1.5 and y=2.75. It means, the yards of silk are 1.5 and yards of cotton are 2.75.
