Answer:
See attachment for graph
<em></em>
Step-by-step explanation:
Given
Required
The graph of the step function
Before plotting the graph, it should be noted that:
and use closed circle at its end
and use open circle at its end
So, we have:
The line stops at -1 with an open circle
The line starts at - 1 and stops at -1 with a closed circle at both ends
The line starts at 1 with an open circle
The options are not complete, so I will plot the graph myself.

Answer:
AB = 11.5mm
Step-by-step explanation:
let the hypotenuse be AC = 23mm
Angle of elevation = 30degrees
Required
Opposite AB
Using the SOH CAH TOA identity
Sin theta = opp/hyp
Sin 30 = AB/AC
Sin 30 = AB/23
0.5 = AB/23
AB = 0.5 * 23
AB = 11.5mm
