Answer:
48
Step-by-step explanation:
If we know that the max possible score is 100%, and she got 80% for getting 60 marks, we can set it up as a porportion.
60 * 80 = 4800
4800/100 = 48
I believe it’s C, because in a recursive rule you must have (n-1), this shows that you’re using the previous term to solve for the next one.
The step function is characteristic of the floor or ceiling functions, which map a real number to an integer. There's clearly a factor of 2, indicated by two units of y for every one unit of x.
The open and filled circles indicate, for example, f(1)=2, f(1.01)=4. That means we're rounding up, so we're using the ceiling function.

Answer: second choice
The Pythagorean theorem tells you that distance is
