Form a sequence that has two arithmetic means between -1 and 59.

Answer:
b
Step-by-step explanation:
The sequence will be arithmetic with 4 terms and a common difference d, which requires to be found.
The n th term of an arithmetic sequence is
= a + (n - 1)d
where a is the first term
here a = - 1, n = 4 and = 59, hence
- 1 + 3d = 59 ( add 1 to both sides )
3d = 60 ( divide both sides by 3)
d = 20, thus the four terms are
-1
- 1 + 20 = 19
19 + 20 = 39
39 + 20 = 59, that is
- 1, 19, 39, 59 → b

Answer:
The volume of cone z has the same base area as cylinder y but its height is 3 times the height of cylinder y have the same volume.
Step-by-step explanation:
The volume of a cylinder having base area 'A' and height 'H' is given by V = AH, and the volume of a cone having the same base area as the cylinder i.e. A and height 3 times the height of the cylinder i.e. 3H is given by .
So, V = V'
Hence, the volume of cone z has the same base area as cylinder y but its height is 3 times the height of cylinder y have the same volume. (Answer)
