First we must look at the sequence 15,9,3,-3...
You can see that the value is decreasing by 6 every term. Because the rate is drawing at a constant rate the sequence must be linear, meaning that the slope is -6.
If we look at the general function of a line in slope intercept form:
where m is the slope and b is the y intercept. The trick to find the y intercept is to go backwards, in other words what was the previous term? 15+6=21. Therefore, m=-6 and b=21 and thus,
Since we want to know the value of y even x=20 we obtain:

Answer:
Step-by-step explanation:
By the Pythagorean theorem, the unknown side has length
Therefore,
Answer:
(8,150)
Step-by-step explanation:
Polar form is in,
(r,theta).
To find r, apply pythagorean theorem using both coordinates to find r.
To find theta, since we know the opposite and adjacent side, apply the tangent function.
Apply inverse tan function
Since the degrees have to be in between 0 and 360. Add 180 to -30.
So the answer is
(8,150).
