Answer:
8
Step-by-step explanation:
This can be solved using intersecting chord theorem. This tells us that when 2 chords intersect inside a circle, the 4 segment it creates, each individual segments' products are equal.
Thus, we can say that the product of 5 and x is equal to the product of 10 and 4. Thus:
Hence x = 8 is the correct answer
Answer:
Option A.
Step-by-step explanation:
The general form of a quadratic function is
It means, power of y should be 1 and highest power of x should be 2.
In option A,
It is a quadratic function.
In option B,
Here, power of y is 2. So, it is not be a quadratic function.
In option C,
Here, highest power of x is 3. So, it is not be a quadratic function.
In option D,
Here, highest power of x is 1. So, it is not be a quadratic function.
Therefore, the correct option is A.
