To convert a percent to a decimal you divide by 100
1.6% = .016
You then multiply .016 times 75.20 which is 1.2032
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:
n = 15
Step-by-step explanation:
6(1+n)=8n-3(n-7)
Distribute
6 +6n = 8n -3n +21
Combine like terms
6+6n = 5n +21
Subtract 5n from each side
6+6n-5n = 5n-5n +21
6 +n = 21
Subtract 6 from each side
6-6+n = 21-6
n = 15
