The answer would be C) because there are 11 possibilities of who can line up first, and after the first person, 10 possibilities, then 9, and so on. So you would need to multiply 11x10x9x8x...x1.
The next number would be 160
Hi there! The answer is D.
The parent function is the simplest form of a function. We can distinguish a variety of parent functions like linear, exponential, square root, absolute, logarithmic, quadratic, cubic, rational or constant (trigonometric functions excluded).
Now we can have a look at the function.

The thing that is the most important in this function is the square root, because this mainly decides the way the function looks. Therefore, the parent function is the simplest form of a square root function, which is the following:

Therefore the answer is D.

Answer:
Jack earned $2560 this summer.
Step-by-step explanation:
Given:
Money given away = $256
Percentile of money give away = 10%
We need to find the total money he earned this summer.
