The answer to the question is actually 3. Hope this helps you!
15 / 5 = 3 your answer is 3
51 degrees = 1/2 (160 -x)
51 = 80 -(1/2)x
102 = 160 -x
x = 58
Answer: (3,4)
Step-by-step explanation:
To find the midpoint, you want to use the formula 
. Since we are given the two points, we can plug them in and solve.
[add numerator]
[divide]
Now, we know that the midpoint is (3,4).
Since you don't need the full answer, here are a couple hints:
- dy/dx is the first derivative
- (d²y) / (dx²) is just the second derivative
- The subscript "x=1" means to find the derivative when x is 1
- X is function of x
- Plug in X into (X² + 3)², the result should be in terms of x
- If the derivatives were calculated properly, the last part of the question should be able to be proved easily.
I hope these tips help
