Answer:
C would be your answer as the formula for the volume of a cone is pi*r²*h/3
Step-by-step explanation:
Answer:
1. 15 - 5n where n>=1
2. n² where n>=1
Step-by-step explanation:
1. {10, 5, 0, -5, -10} is an Arithmetic Progression
nth term is a + (n - 1)d
where a = first term, n= nth term, d= common difference.
a = 10, d = -5 (5-10, 0-5, -5-0, -10-(-5))
Therefore, nth(General) term of the sequence:
= 10 + (n - 1)-5
= 10 + (-5n) + 5
= 10 + 5 - 5n
= 15 - 5n
Test:
if n = 1; 15 - 5(1) = 10
if n = 2; 15 - 5(2) = 5
if n = 3; 15 - 5(3) = 0 and so on.
2. {1, 4, 9, 16, 25}
The general term of the sequence is n²
Test:
if n = 1; 1² = 1
if n = 2; 2² = 4
if n = 3; 3² = 9 and so on.
Answer:
n = 2m
Step-by-step explanation:
total number of movies = 2 movies every month times the number of months
Answer:
47
Step-by-step explanation:
The diagonals of a parallelogram bisect in their middle point, so :
2u + 9 = 5u - 48
3u = 57
u = 19
EI = 5* 19 - 48 = 47
