Answer:
C
Step-by-step explanation:
There is a common ratio between consecutive terms
r = 24 ÷ 16 = 36 ÷ 24 = 54 ÷ 36 = 1.5 = 
This indicates the sequence is geometric with nth term ( explicit formula )
f(n) = a₁
where a₁ is the first term and r the common ratio
Here a₁ = 16 and r =
, then
f(n) = 16
→ C
Answer:
the answer is 180
Step-by-step explanation:
12 multiply 15.
Answer:
The answer is 20pi
Step-by-step explanation:
perimeter of a semicircle = pi* radius
perimeter of first semicircle = 5.pi
perimeter of second semicircle = 5.pi
perimeter of third semicircle = 10. pi
total perimeter = 5pi +5pi + 10pi
= 20pi
The common difference can be found from

The first term of the sequence can be found from either of the given terms.

The sum of 40 terms is

The sum of the first 40 terms is 3800.
The transformation will lie in Quadrant III
