Step-by-step explanation:
B
Answer:
(x - 7)^2 + (y - 2)^2 = 5^2
Step-by-step explanation:
Center at (7, 2); radius 5
Adapt (x - h)^2 + (y - k)^2 = r^2 to this situation. Replace h by 7, k by 2 and r by 5:
(x - 7)^2 + (y - 2)^2 = 5^2
Answer:
The required rate of interest = 14.285%
Step-by-step explanation:
Here, The principal amount = 7,000
The final paid amount = 9,000
Time = 2 years
Let us assume the rate of interest = R
Now, Simple Interest = Amount - Principal
= 9,000 - 7,000 = 2,000
So, the SI on the given principal for 2 years = 2,000

or, R = 14.285%
Hence, the required rate of interest = 14.285%
