Answer:
a) d²y/dx² = ½ x + y − ½
b) Relative minimum
Step-by-step explanation:
a) Take the derivative with respect to x.
dy/dx = ½ x + y − 1
d²y/dx² = ½ + dy/dx
d²y/dx² = ½ + (½ x + y − 1)
d²y/dx² = ½ x + y − ½
b) At (0, 1), the first and second derivatives are:
dy/dx = ½ (0) + (1) − 1
dy/dx = 0
d²y/dx² = ½ (0) + (1) − ½
d²y/dx² = ½
The first derivative is 0, and the second derivative is positive (concave up). Therefore, the point is a relative minimum.
Answer: Luis earned $997.00 for last week.
$6,050.00 - 14%= $5,203.00
Just figure the difference ($847)
Then add his base salary.
I cant help you there m8 the I'm not able to see the problem I'm sorry.
The Answer is....
x=-3 and y=3
(-3,3)
First replace y with 15.
1/5x-10=30
Then just solve from there.
x=200
