Consider the set of points defined by z = 5 cos(theta) + 3i sin(theta).

Answer:

This is an ellipse.

Step-by-step explanation:

z=5cos(\theta)+3isin(\theta)

Applying the angle values in intervals of right angles (90°), the resulting set of values for z are:

\theta = 0,90,180,270,360

z=5,3i,-5,-3i,5 (again)

If you look at the plot, you will observe how these values represent points in the xy plain. All of them belong to either the x or the y axis.

The resulting figure for the whole set of values of \theta is in fact an ellipse.

What is the slope of the line that passes through (3, 3) and (-2, -3).
Diano4ka-milaya [45]

Answer:

slope=6/5

Step-by-step explanation:

The formula for finding the slope is y1-y2/x1-x2=slope. So if we substitute in the numbers from you question, it would be (-3-3)/(-2-3)=slope

(-3-3)/(-2-3)=slope

-6/-5=slope

6/5=slope
