Answer:
B
Step-by-step explanation:
logₓ 7 = 3
x³ = 7
Take cube root both sides

Answer:
Option A
Step-by-step explanation:
Given:
Center of circle = (h,k)= (3,8)
Radius = r = 5
The standard form of equation of circle with center and radius is:

Therefore, the general form of the equation of circle given is:

Hence, option A is correct ..
To solve this you need to take the answer from the previous iteration.
Iteration 1: The answer is given
a1 = 300
Iteration 2: Solve using the equation. a(n-1) is the answer from the previous iteration. n = the number of the current iteration. So, a(n-1) = 300 and n = 2
a2 = 300/2 = 150
Iteration 3: a(n-1) = 150 and n = 3
a3 = 150/3 = 50
Iteration 4: a(n-1) = 50 and n = 4
a4 = 50/4 = 12.5
Answer: 12.5
