Answer:
Li Jing's formula i.e. 
is right.
Step-by-step explanation:
Considering the sequence
A geometric sequence has a constant ratio r and is defined by
So, the sequence is geometric.
as
so
Therefore, Li Jing's formula i.e. is right.
The monthly payment for the new car is; Choice A; $279. 03
<h3>Percentages</h3>
After the down payment of 30% and financing the 8% TT&L is made; it follows that;
The rest of the payment is;
Hence, $8,897 is the payment made over the course of the duration at a finance rate of 3.16%.
Ultimately, the monthly payment is; $8,897 × 0.0316 = $279.03

Answer:
Percentage of Taxes = 10.689 %
Step-by-step explanation:
Given that
Total earning of Anna is $442.50
The amount which is held with Taxes = $47.30
Now in terms of percentage
percentage of taxes from her total earning = 
So % taxes = ( 0.106892) × 100
∴ Taxes percentage = 10.689 %
The standard forrm equation of the circle is (x-h)² + (y-k)² = r²
where h,k : x,y-coordinate of the center
r : radius of the circle
Get the center of the circle : h = (x1 + x2)/2 = (9+5)/2 = 7
k = (y1 + y2)/2 = (4+2)/2 = 3
=> the center is (7,3)
Because the given information gave 2 endpoints so we can choose one of these, then use the distance formula to get the radius
r = √(x1 - h)² + (y1 - k)²
r = √(9 - 7)² + (4 - 3)²
r = √2² + 1²
r = √5
Finally, the equation of the circle is (x - 7)² + (y - 3)² = (√5)²
(x - 7)² + (y - 3)² = 5
