Well I would solve it but where's the problem?
The general form of the equation of a circle with radius ' r '
and centered at (a, b) is
(x - a)² + (y - b)² = r²
I'm pretty sure that your circle is not "at (-2,1)".
I'm going to approach your question assuming that
the circle's center is there.
Since the circle's center is at (-2, 1), the left side of its equation is
(x + 2)² + (y - 1)² = .
The distance from the center to (-4, 1) is the circle's radius.
That distance is 2, so the right side of the equation is
4 .
Answer:
$687.42
Step-by-step explanation:
The total with tax is ...
(price) + (tax rate)×(price)
= price(1 +tax rate)
= $643.95×1.0675 ≈ $687.42 . . . price with tax

The image to the question is missing, but I found a matching image, which is attached to this solution
Answer:
3 minutes = 13 dots
100 minutes = 401 dots
t minutes = 4(t) + 1 dots
Step-by-step explanation:
From the image, the following can be noticed:
time (Mins) dots
0 1
1 5
2 9
The pattern gotten from this progression is that, if the time is multiplied by 4, and the result added to one, the result will be the number of dots.
hence, when the time is 0 minutes:
0 × 4 = 0
0 + 1 = 1 ( 1 dot)
when the time is 1 minute
1 × 4 = 4
4 + 1 = 5 (5 dots)
when the time is 2 minutes
2 × 4 = 8
8 + 1 = 9 ( 9 dots)
Therefore,
when the time = 3 minutes
3 × 4 = 12
12 + 1 = 13 dots
at 100 minutes:
100 × 4 = 400
400 + 1 = 401 dots
at t miutes
t × 4 = 4t
4t + 1 = number of dots
Therefore number of dots at t minutes = 4(t) + 1
