Answer:
choice 1
Step-by-step explanation:
Given
V = πr²h ( isolate r² by dividing both sides by πh )
= r² ( take the square root of both sides )
= r ← the positive value of r
Four and two hundred ninety-three thousandths
Answer:
well this is according to my calculator
Step-by-step explanation:
the answer is 506
Answer:
The model for V(t) ,the number of views, t ,months after it's uploaded, best fits the data is 
Step-by-step explanation:
Time (months) Views
0 50
2 313
4 1950
6 12,210
8 76,300
10 476,800



Slope =131.5


Slope =818.5
Since the slope is not same . So, it is not a linear relationship

Since the ratio between the consecutive outputs is same so, it is exponential relationship.
Formula : 
Where a is the initial value = 50
b = rate of change = 6.25
The model for V(t) ,the number of views, t ,months after it's uploaded, best fits the data
So
Step-by-step explanation:
Given
-30 = - 0.4 k
30 = 0.4k
k = 30 / 0.4
k = 75
hope it helps :)
