Answer:
512 mph
Step-by-step explanation:
The relevant relation is ...
speed = distance/time
speed = 1792 mi/(3.5 h) = 512 mi/h
The plane's average rate of speed should be 512 miles per hour.

4x^2-8x-12 =
(x -3) * (x +1)
4x^2-24x+32
</span><span>(x -4) * (x -2)
</span>Factored Form
(x -3) * (x +1) * <span>(x -4) * (x -2) = 0
x = 3
x = -1
x = 4
x = 2
All four roots are real numbers and so the graph crosses the x-axis four times. The graph of the equation would resemble a "W".

Answer:
36.869 or 36.87
Step-by-step explanation:
first, you find which trig function you are using. in this case, tangent.
then, you put calculate the arctan(3/4) which is 36.96989765
