After special medicine is introduced into a peril dish full of bacteria, the number of bacteria remaining in the dish decreases
rapidly. The relationship between the elapsed time t, in seconds, and the number of bacteria, N(t), in the Petri dish is modeled by the following function:
N(t)=50,000•(0.5) t/4.3
The Petri dish loses %50 of bacteria every ____ seconds
N(t)=50,000•(0.5) t/4.3
The Petri dish loses %50 of bacteria every ____ seconds

Answer:
<em>Thus, the dimensions of the desk in the drawing are 4 cm long and 2 cm wide.</em>
Step-by-step explanation:
<u>Scaling</u>
The scale factor established to represent a desk 2 meters long and 1 meter wide is:
1 centimeter = 0.5 meter
We need to convert the real dimensions to the scaled dimensions. To complete the task, it's a good idea to multiply the real dimensions by the ratio:
to get the scaled dimensions.
The length of 2 meters is scaled to:
And the width of 1 meter is scaled to:
\displaystyle 1\ m\frac{1\ cm}{0.5\ m}=2 cm
Thus, the dimensions of the desk in the drawing are 4 cm long and 2 cm wide.
Answer:
Step-by-step explanation:
Use this formula,
where n is the amount of even intergers, a is the starting term, d is the common difference.
- the amount of even intergers from 2 to 200 is 100
- The starting number is 2
- The common difference is 2
