This is exponential growth...
f=ir^t, f=final amount, i=initial amount, r=rate, t=time
f=2r^t so we have a point at ten minutes that says:
8=2r^10
4=r^10
r=4^(1/10) so our equation is:
f=2(4^(1/10)^t)
f=2(4^(t/10)) now we wish to solve for t when f=16
16=2(4^(t/10))
8=4^(t/10) taking the natural log of both sides...
ln8=(t/10)ln4
t/10=ln8/ln4
t=10(ln8/ln4)
t=15
So after fifteen minutes there will be 16 cells in the bottle...
10:05+:15=10:20
So at 10:20 there will be 16 cells in the bottle.
Answer: 6 feet describes the center, and 9 feet describes the spread
Step-by-step explanation:
The center of a data set is mostly considered as the median or the mean
Here mean is 6 (given). And median is also 6. As 6 is exactly at the middle of the data set. (When arranged in ascending order)
Now, one of the way of calculating the spread is calculating the range, here it's given that the range is 9.
Therefore, 6 feet describes the center, and 9 feet describes the spread is correct.
Answer will be 1 because it’s by its self or it could be 2
The correct answer is option D.
Answer:
-7
Step-by-step explanation:
y = mx + b is slope-intercept form and m is the slope. In this case m = -7 so the slope is -7.
