Answer:

234 feet

Step-by-step explanation:

To find the volume of a rectangular prism, all you really need to do is multiple the length, width, and height (LxWxH)

(4.5*6.5) = 29.25

29.25*8= 234

The population size after 6 years and after 8 years are 147 and 169 population respectively

<h3>Exponential functions</h3>

The standard exponential function is expressed as y = ab^x

where

a is the base

x is the exponent

Given the function that represents the population size P (t) of the species as shown;

$p(t)=\frac{550}{1+5e^{-0.1t}} \\$

For the population size after 6 years

$p(t)=\frac{550}{1+5e^{-0.1(6)}} \\P(6)=\frac{550}{3.744}\\ P(6)=147 population$

For the population after 8 years

$p(t)=\frac{550}{1+5e^{-0.1(8)}} \\P(8)=\frac{550}{3.2466}\\ P(8)=169 population$

Hence the population size after 6 years and after 8 years are 147 and 169 population respectively

If there are initially 1800 bacteria in a culture, and the number of bacteria double each hour, the number of bacteria after t h

Nataly_w [17]

Answer: 1.58 hours

<u>Step-by-step explanation:</u>

$5400=1800(2)^t\\\\3=2^t\\\\ln\ 3=ln\ 2^t\\\\ln\ 3=t\cdot ln\ 2\\\\\dfrac{ln\ 3}{ln\ 2}=t\\\\1.58=t$
