Hi Vance :)

a=leg unknow
b=leg
c=hypotenuse

a²+b²=c²
a²=c²-b²
a²=145² - 144²
a²=21,025 - 20,736
a²=289
a=√289
a=17

unknow leg = 17 units

Axis of symmetry y=x^2-4x+1
Andrei [34K]

So for a quadratic function, the axis of symmetry is the line that divides the curved line in the middle, which is the h value, it can be found by using the formula -b/2a, so for here it would be 4/2(1) = 2, so x =2

Hope that answers your question
