Answer:
x1= -6.6 x2= 8.6
Step-by-step explanation:
f(x) = x² + 2
y = x² + 2
x = y² + 2
x - 2 = y²
√(x - 2) = y
√(x - 2) = f⁻¹(x)
The two planes are flying in opposite directions.One plane travels at 560miles per hour and the other travels at a speed of 500 miles per hour. As time proceeds, they would travel further from each other and that can be described by the equation that follows:
560(t)+500(t) =2000, since we are given a 2000 distance limit. Then we are to find the time when they are at this distance. Solve for t, which is equal to 0.53 hours or 32 minutes.
