Answer:

Step-by-step explanation:
The function seems to increase at a constant rate of 3 units. This means that the equation that satisfies these points could be that of a straight line.
We use the first two points to find the slope of the line.
(0, -10)
(1, -7)
(2, -4)
The equation of a line is:

Where m is the slope of the line and b is the cutoff point with the y axis.
To find the slope of a line we use the following equation:


So:

The cut point (b) is found by replacing in the previous equation, any of the three points provided and clearing b.


Now we can write the equation of the line sought.

You can verify that the three points provided belong to this equation.
Answer:
C. 30
Step-by-step explanation:
15 men do work in 16 days
This means that 7.5 men (15/2) would do that same work in 32 days (16x2).
If the number of men increase, the amount of days decrease.
8 men would do that work in 30 days
8 men > 7.5 men
30 days < 32 days
Hello,
since sin 30°=1/2 and cos 30°=√3/2
then
8(cos 30+i sin 30°)=8*(√3/2+i/2)=4√3+4i
