Answer:
Step-by-step explanation:
Here are some formulas that you might need.
The vertex of graph is at (h, k) from the vertex form.
Substitute in the formula.
Next we find the value of k.
Therefore the vertex is (4,-10).
Polar form of a complex number is r( cos(theta) + i sin(theta) )
r is equal to the total distance created by the rectangular coordinates of the complex number
r = Root(4^2 + (-4)^2) = Root(32) = 4 Root(2)
To find theta, if a > 0, use arctan(b/a), where:
a = the first number
b = the second number
arctan (-4/4) = -45 degrees (-0.7854 radians)
Your answer is 4 Root(2) (cos(-45) + i sin(-45))
I think you need to add all those numbers up. Hope this helps:)
D. Line Graph
It can give you a clearer illustration of how long someone plays a video game.
P.S. my line would probably run off the grid. :-)<span />
