Answer:
(-9, π/5 + (2n + 1)π)
Step-by-step explanation:
Adding any integer multiple of 2π to the direction argument will result in full-circle rotations, which are identities, so this family is equivalent to the give coordinates:
(9, π/5 + 2nπ), for any integer n
Also, multiplying the radius by -1 is a point reflection, equivalent to a half-turn rotation. Then add π to the direction for another half turn, and the result is another identity. So this too is equivalent to the given coordinates:
(-9, π/5 + (2n + 1)π), for any integer n
Answer:
x-y=5 just solve it to get the answer
<span>A. cos(x) = cos(-x) [correct, since cos(x) is an even function]
B. Since the cosine function is even, reflection over the x-axis [y-axis] does not change the graph. [false]
C. cos(x) = -cos(x) [ false]
D. The cosine function is odd [even], so it is symmetrical across the origin. [false]</span>
2d +9= 19
The solution is d =
Hello there, first we can place our equation, which you have stated
, this algebra, in algebra we want to find the exact value of the variable, or have the variable on one side of the equation.
First we can subtract 
with both sides of the equation giving us the result of 
, this can also be represented as 
, now just divide both sides of the equation by 
, our answer is 
.
