We can use proportion to get the result
10 ----------- 5%
x ------------- 100%
Crossmultiply proportion

5*x=10*100
5x=1000 /:5 divide both sides by 5
x=1000:5
x=200 - its the answer

Answer the following True or False:

Ilia_Sergeevich [38]

False; consider as a counterexample the function f : ℝ→ℝ defined by

$f(x)=\begin{cases}-3&\text{for }x\neq2\\0&\text{for }x=2\end{cases}$

Clearly f approaches -3 as x gets closer to -2, but neither limit from either side is equal to the function's value at x = 2 (that is, -3 ≠ 0), so f is not continuous.

A pair of events are observed to have coordinates (0s,0m) and (50.0s,9.00×109m) in a frame s. what is the proper time interval δ

Ludmilka [50]

To find out time interval δt we need to substract initial time from the final time. In this question first number in the coordinates representes time:

δt=50 - 0
δt= 50s

TIme interval is 50s.
