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:
D) f(x) = 6x
Step-by-step explanation:
Answer:
its the last one hun
Step-by-step explanation:
Answer:
d
Step-by-step explanation:
Soooo,
d = 2r
(29) = 2r
29/2 = 2r/2
14.5 = r
This would be 10-2 which would equal 8
