ANSWER
See attachment.
EXPLANATION
The given function is

When we compare this function to

We have a=1, b=4 and c=5
We put this inside the formula for the discriminant, which is



Since the discriminant is negative, the function has no x-intercepts.
The graph of this function is the one hanging in the air above the x-axis and opens upwards.
If Each side of an equilateral triangle<span> is 10 m. ... Thus </span>triangle<span> APC is a right</span>triangle<span>. The length of CA is 10 m, and the length of PC is 5 m, and hence you can use Pythagoras' theorem to find the length of AP, which </span>is the height<span> of the </span>triangle<span>ABC.
