$988
The before-tax price is then p = ---------- = $950 (answer)
1.04
Step-by-step explanation:
Use Pythagorean theorem:
c² = a² + b²
Here, c = 42 and a = 31.
42² = 31² + b²
b = √803
b ≈ 28.3
Any function that has a -b value divided by 2a that equals -2
use ax²+bx+c to figure it out
the axis of symmetry formula is -b/2a=x
