First option:
Step-by-step explanation:
The missing graph is attached.
The equation of the line in Slope-Intercept form is:
Where "m" is the slope and "b" is the y-intercept.
We can observe that:
1. Both lines have the same y-intercept:
2. The lines are solid, then the symbol of the inequality must be or
.
3. Since both shaded regions are below the solid lines, the symbol is:
Based on this and looking at the options given, we can conclude that the graph represents the following system of inequalities:
Answer:
Step-by-step explanation:
1). Geometric mean of a and b =
Therefore, geometric mean of 2 and 50 =
= 10
2). By geometric mean theorem,
e² = 6 × 24
e = √144
e = 12
Similarly,
d² = 6 × 30
d = √180
d = 6√5
And
c² = 30 × 24
c = √720
c = 12√5
