The greater than 3 means that the graph will have a shaded region for when the absolute value of (x+1) is greater than 3.
The absolute value means that we are interested in the magnitude of x+1. That means that the the graph will be shaded where x+1 > 3, and where -x-1 > 3
If we solve both of these for x, we get:
x > 2 and x < -4
So the graph will look like the attached picture. Notice that the vertical lines are dotted rather than solid. This means that we are dealing with a greater than sign, not a greater than or equal to.

Answer : 82.27cm²
Method :
First work out the area of the semi circle.
To do this we find the area a circle and half it.
The radius of the semi circle is 4.
To find the area of a circle is it radius² x π
Therefore the area of the semi circle is 4 ² x π
Then divide this by 2.
Then you should get 16 π which equals 50.26548246 cm ².
Then find the area of the triangle.
The area of a triangle is base x height divided by 2.
Therefore you should get 9 x 8 divided by 2 which you should get to 36 cm ².
Then add the two together to get
86. 26548246.
Then round to the newest hundredth to get to the final answer of 86.27cm².
Answer:
5/6
Step-by-step explanation:
The factors of 24 that are on a die are: 1,2,3,4 and 6. This only leaves 5 that isn't a factor of 24. Therefore, since there are 5 possibilities out of the 6 total numbers, the probability of rolling factors of 24 is 5/6.
