What you have to do is multiply 21 by 2. it is 42. $42 dollars was the original price of the bookcase.
Using an exponential function, it is found that the population of bacteria in the culture after 13 hours is of 1,491,747.
An <em>exponential function</em>, with a <u>doubling time of d, after t hours</u>, is given by:
- In which A(0) is the initial amount.
In this problem:
- The doubling time is of 3 hours, hence .
- The initial population is of 74000 bacteria, hence .
Then:
After 13 hours:
The population of bacteria in the culture after 13 hours is of 1,491,747.

For this case we observed that the cross section after the cut is rectangular.
Because the cake is a rectangular prism then:
The cross section is perpendicular to the base of the cake.
Answer:
perpendicular to the base.

h = 7 m
Volume of cylinder
As a decimal its 5.00 but u could just drop off the zeros that would be 5 still right as a fraction it would be 5 over 10 when u simplfy it would be 1 over 5
