Answer:
trapezoid
Step-by-step explanation:
There is only one group of shapes that could be a trapezoid
A square, a rectangle, a rhombus, a trapezoid, a kite, and other 4-sided shapes fall under the category of quadrilateral
A rhombus, a parallelogram, and a square are all rhombuses
 
        
             
        
        
        
Answer:

The doubling time is of 27.65 minutes.
Step-by-step explanation:
Exponential equation of growth:
The exponential equation for population growth is given by:

In which P(0) is the initial value and k is the growth rate.
A freshly inoculated bacterial culture of Streptococcus contains 100 cells.
This means that  . So
. So

When the culture is checked 60 minutes later, it is determined that there are 450 cells present.
This means that  , and we use this to find k. So
, and we use this to find k. So






So

Doubling time:
This is t for which P(t) = 2P(0) = 200. So






The doubling time is of 27.65 minutes.
