<h2>
The top of the ladder is descending at 0.3 m/s.</h2>
Step-by-step explanation:
By Pythagoras theorem we know that
Hypotenuse² = Base² + Perpendicular²
h² = b² + p²
We have for ladder
h = 5 m
b = 3 m
5² = 3² + p²
p = 4 m

Differentiating h² = b² + p² with respect to time

The top of the ladder is descending at 0.3 m/s.
Answer with explanation:
Relation between Speed , Distance and time
Distance =Speed × Time
→It means Speed is inversely Proportional to time.
As distance will remain constant , in that frame of reference
If speed of light in a Medium

Then, time taken to cross the medium = t seconds or hours or another unit of time.
Now, If speed of light is 50% of the speed of light relative to us
That is Speed of light in another medium

Then, time taken to cross the medium = 2t seconds or hours or another unit of time.
Using Unitary Method

Answer:
15
Step-by-step explanation:
6x+11 > 7x-2
2+11 >7x-6x
13>x
15 is more than 13 which does not satisfy the inequality.
X has to be less than 13 and cannot even equal 13 as that is not the sign
Answer:
A=$1, 114.91 is the answer. Hope this helps!
