To address this problem, let's start by formulating the general motion equation along the vertical direction.
This gives us:
Where,
For the first individual:
For the second individual:
When both individuals reach the identical altitude, the following holds:
Rearranging results in:
Solving for time:
Result:
The two window washers reach the same height after 18.31 seconds.
Answer: A square that undergoes rotation around its center by 360º aligns with itself at D) 4 distinct angles during the process. Furthermore, a square can be reflected onto itself over B) 4 various lines.
Explanatory breakdown:
A square is a geometric shape characterized by equal-length sides and right angles ( ).
Thus, it is capable of being rotated around its center by .
It reverts to its original outline at 4 unique rotation angles ( at every ).
The square can also be reflected onto itself across 4 lines (2 through the non-parallel sides and 2 through the corners).
Response:
12.
Step-by-step explanation:
We have been given a format for various numbers. Our task is to discover the missing value for our specified format.
Taking the square root of 9 and 16 results in
Moreover, it can be observed that by computing the square root of all figures on the left side of the equation and summing them, we arrive at the right side.
Upon extracting the square roots of 25 and 49 we deduce,[TAG_48]]
Therefore, the missing number in our sequence is 12.
