Step-by-step explanation:
Answer:
xA = 10 km
xB = 7.071km
Step-by-step explanation:
A/Q
p=5km
For point A
∅ = 30°
sin ∅ = p/h
sin 30° = 5/h
1/2 = 5/h
h = 5×2
h=10km
For point B
sin ∅ = p/h
sin 45° = 5/x
1/√2 = 5/x
x = 5 × √2
x = 7.071 km
.: Points A and B are 10 km and 7.071 km away from the airplane.

Answer:
- the graph does not cross the x-axis
- the solutions are x = -8, x = 4.
Step-by-step explanation:
The given equation graphs as two points on the number line:
_____
In order for the graph of a function of x to cross the x-axis, there must be a function of x. The given equation is an equation that is true only for specific values of x. <em>It is not a function of x</em>.
If you want to graph y = x^2 +4x -32, you will find it crosses the x-axis 2 times.
___
<em>About the attachment</em>
The blue line is a graph of the left side of the given equation. It crosses the x-axis 1 time. The green curve is a graph of the right side of the given equation. It crosses the x-axis 2 times, in different places than the blue line. The x-values of the points where the blue and green curves intersect are the solutions to the equation.
The red curve is the proposed function of x (above). It crosses the x-axis 2 times.
