First find the value of m by solving the inequality.
Solving the inequality we get value of m: m>-4
Now, for drawing the graph, a dotted line will be on -4, as values greater than -4 are included in the graph. and all the portion on right side of -4 is included in the graph.
Step-by-step explanation:
We need to draw the graph of the solution set for the following inequality.
First we will solve the inequality and find value of m
Adding -18 on both sides
Dividing both sides by -3 and reversing the inequality i.e < is changed into >
So, value of m is: m>-4
So. for drawing the graph, a dotted line will be on -4, as values greater than -4 are included in the graph. and all the portion on right side of -4 is included in the graph.
The graph is shown in figure attached.

Answer:
- 11.26 cm²
Step-by-step explanation:
The shaded region is the difference of areas of semicircle AB and triangle ABC.
ABC is right triangle as AB is diameter, so C is right angle.
<u>Area of semicircle:</u>
- A = 1/2πr² = 1/2*3.14*4² = 25.12 cm²
<u>Area of triangle:</u>
- A = 1/2BC*AC = 1/2*4*
= 2
= 13.86 cm²
<u>Shaded are is:</u>
- 25.12 - 13.86 = 11.26 cm²
