The answer is: A. 20.3
The explanation is shown below:
1. By definition, the sum of the length of the strings (The length of the blue segment and the length of the red segment) is equal to the length of the major axis (The black segment).
2. Based on this, you can write the following expression, where 
is the length of the blue segment:
3. Now, you must solve for , as following:
4. Therefore, the answer is the option A.
Well the first obvious thing is that the axis of symmetry is 0.5, so we can automatically cross out (C).
All the answers have the correct vertex, so lets find the formula for the function.
Fortunately, from my point of view, I can see two points that have their coordinates as integers, (-1, -3) and (2, 3), we can plug these into the already given "formulas" in the options (A), (B), and (D).
Out of the three choices, the formula in option (D) satisfies both coordinates, thus option (D) is correct.
Answer:
The fraction is less than 
.
Step-by-step explanation:
Let the fraction is 
.
Given that when the fraction of 17 is subtracted from 17 itself, then the remaining will be greater than one-third of 17 divided by six.
Therefore, by the given condition,
⇒ 
⇒ 
⇒ 
⇒ 
Therefore, the fraction is less than . (Answer)
40x 60 = 2400. so the area could be 2400.
Answer:
B
