Explanation:
In order to prove that affirmation, we define the function g over the interval [0, 1/2] with the formula 
If we evaluate g at the endpoints we have
g(0) = f(1/2)-f(0) = f(1/2) - f(1) (because f(0) = f(1))
g(1/2) = f(1) - f(1/2) = -g(0)
Since g(1/2) = -g(0), we have one chance out of three
- g(0) > 0 and g(1/2) < 0
- g(0) < 0 and g(1/2) > 0
- g(0) = g(1/2) = 0
We will prove that g has a zero on [0,1/2]. If g(0) = 0, then it is trivial. If g(0) ≠ 0, then we are in one of the first two cases, and therefore g(0) * g(1/2) < 0. Since f is continuous, so is g. Bolzano's Theorem assures that there exists c in (0,1/2) such that g(c) = 0. This proves that g has at least one zero on [0,1/2].
Let c be a 0 of g, then we have

Hence, f(c+1/2) = f(c) as we wanted.
The answer is ........

Answer:

Step-by-step explanation:
To write the equation of a circle, use the formula
where the center of the circle is (h, k).
This means the equation is
.
Find the radius r by dividing the diameter of 10 in 2. The radius is 5.
So the equation of the circle is 
Answer:
52 miles per hour.
Step-by-step explanation:
Divide 234 by 4.5, as that is what you must divide 4.5 by to get 1.
234/4.5 = 52 miles per hour.
Step-by-step explanation:
Answer: 16 and 5/4 tbsp of sugar.
7 ÷ 2 = 3.5
Don't worry about the decimal for now, just find how many tbsp of sugar she needs for 6 tbsp of milk.
6 ÷ 2 = 3
3 x 5 = 15
Now, we will focus in the 0.5 tbsp of milk.
Find how much 1/2 a tbsp of milk can get for sugar.
4 1/2 tbsp of milk is 5 tbsp of sugar.
5 ÷ 4 = 1.25
So 16 and 5/4 tbsp of sugar is required.
