Answer:
<h2><u><em>
3.2$ and 4.8$</em></u></h2>
Step-by-step explanation:
divide $8 in the ratio 2:3
8 : (2 + 3) = 1.6 (unity)
1.6 * 2 = 3.2 (ratio2)
1.6 * 3 = 4.8 (ratio 3)
----------
3.2 + 4.8 = 8
the answer is good
Answer: Option d.
Step-by-step explanation:
You can solve the problem shown above keeping on mind the facts shown below:
Observe that there is a point in the graph in which there is a jump or a discontinuity between both parts of the function.
The point mentioned is at x=5
By definition, this indicates that the function shown is not continuous at that point.
Therefore, you can conclude that the value in which the graph is discontinuous is the value of the option d: 5
