-29
Step-by-step explanation:
Problem 1
In the first hour, the number of bacteria is 22
In the second hour,the number of bacteria is 44
It looks like the formula is some multiple of 22
That means you should pick D
Problem 2
n = 12
a = 15
d = - 4
an= 15 + (n - 1)*d
a12 = 15 + 11*(-4)
a12 = 15 - 44
a12 = - 29
Asks for x part of the solution. that is ,-2

Answer:
Yes, r and h can be changed to produce same volume by;
Increasing "r" and decreasing "h" or by decreasing "r" and increasing "h".
Step-by-step explanation:
What the question is simply asking is if we can get same volume of a particular cylinder if we change the radius and height.
Now, volume of a cylinder is;
V = πr²h
Now, for the volume to remain the same, if we increase "r", it means we have to decrease "h", likewise, if we decrease "r", we now have to increase "h".
