2 answers:
Answer: The correct options are
(B) +11
(C) -11.
Step-by-step explanation: We are given to select the numbers from the options that are 11 units from 0 on the number line.
We know that
the distance between a and b on the number line is given by
where b is greater than a.
So, we have
the distance between 0 and 0 on the number line is
The distance between +11 and 0 is
The distance between -11 and 0 is
Thus, the required numbers that are 11 units from 0 are +11 and -11.
Options (B) and (C) are CORRECT.

Answer:
Trampolinist will land on the trampoline after 0.9 seconds.
Step-by-step explanation:
The function h(t) = -16t² + 15 represents the relation between height 'h' above the ground and the time 't' of the trampolinist.
We have to find the time when trampolinist lands on the ground.
That means we have to find the value of 't' when h(t) = 15 - 13 = 2
[Since trampoline is 2 feet above the ground]
When we plug in the value h(t) = 2
2 = -16t² + 15
2 + 16t² = -16t² + 16t² + 15
16t² + 2 = 15
16t² + 2 - 2 = 15 - 2
16t² = 13
t =
t ≈ 0.9 seconds
Therefore, trampolinist will land on the trampoline at 0.9 seconds.
