Answer:
it's c
Step-by-step explanation:
Answer:
a)
b) 334,858 bacteria
c) 4.67 hours
d) 2 hours
Step-by-step explanation:
a) Initial number of bacteria is the coefficient, that is, 250. And the growth rate is the coefficient besides “t”: 0.15. It’s rate of growth because of its positive sign; when it’s negative, it’s taken as rate of decay.
Another way to see that is the following:
Initial number of bacteria is N(0), which implies . And . The process is:
b) After 2 days means . So, we just replace and operate:
c)
d)
Slope is -1/5
Y-intercept is 21
Equation is y=-1/5x+21
Yes it’s proportional :)
f(x)=20+300x
Also, Rex should find a different pool because that fee is ridiculous.
There are 24 Faces.
bc-
V = 14, E = 36, F = ?
F + 14 - 36 = 2
F - 22 = 2
F = 24
