Answer:
Step-by-step explanation:
We know that if a figure is reflected across y axis then its y coordinate remains same but the x coordinate changes its polarity.
i.e. the function will become
.
Now, the given function :
Then , after reflection across y axis the new function will become:
The length of the smaller leg is 3.79
<h3>How to determine the length of the smaller leg?</h3>Represent the smaller leg with x.
So, we have:
-- Pythagoras theorem
This gives
2x^2 = 144/5
Divide by 2
x^2 = 72/5
This gives
x^2 = 14.4
Take the square root
x = 3.79
Hence, the length of the smaller leg is 3.79
