In order to find the discriminant:
b^2-4ac
A= 1, B= 6, C=8
(6)^2-4(1)(8) = 4
Therefore, the equation has one real solution
Answer:
40000ftMSL
Step-by-step explanation:
We know that airspeed is measured using a pilot tube
And the air pressure is a function of density given as
Pressure= 1/2 xdensityx V²
So at 40,000ftMSL
Is this is replaced for V in the equation then the density of air will be 1/4 that of sea level
So since we are deriving velocity from pressure and pressure is 1/4 so the velocity Will be half of its pressure since velocity is squared from The equation above
Answer: y=54
Step-by-step explanation: since a triangles angles =180 and you just have this equation 180-72=2y that equals 108=2y
