To get the Area you need the Radius to get the Radius you need to divide 14 by 2 14/2=7
The Radius is 7 now to get the area we need to multiply 7 by 7 but also add pi 3.14
7*7*3.14=153.86
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.
2 becuae......................................................................................................you have 5/10
D because if you multiply y 8 times it will no longer be doubling the area
