Answer:
1. -0.86
2. -0.96
Step-by-step explanation:
used calculator :)
It is the second one :1 is not in the domain of f*g
2(l + b) = 27.2
2(l + 7.9)= 27.2
2l + 15.8 = 27.2
2l = 11.4
l = 5.7 ft
Answer:
E
Step-by-step explanation:
In this question, it is given that
A certain bacteria culture grows at a rate of 18% everyday. There are currently 420 bacteria.
And we have to find number of bacterias on day *.
For that we use the following formula
![N(t) =N_{0} (1 +r)^t](https://tex.z-dn.net/?f=N%28t%29%20%3DN_%7B0%7D%20%281%20%2Br%29%5Et)
![N(0)= 420, r = 0.18 , and \ t = 8days](https://tex.z-dn.net/?f=N%280%29%3D%20420%2C%20r%20%3D%200.18%20%2C%20and%20%5C%20t%20%3D%208days)
Substituting these values in the formula, we will get
![N(8)= 420(1+0.18)^8 \\ N(8)=1579](https://tex.z-dn.net/?f=N%288%29%3D%20420%281%2B0.18%29%5E8%0A%5C%5C%0AN%288%29%3D1579)
THerefore on day 8, number of bacterias are 1579.
