Suppose you're performing experiments in science class in which you start with 70 bacteria and the amount of bacteria triples every hour. write a function to represent the growth of the bacteria overtime in your science experiment

The function to represent the growth of bacteria will be

a=70*3^b

a is the number of bacteria at time b

b is the number of hour(time)

Explanation:

As per the given information You start your experiment with 70 bacteria,and the bacteria triples in every hour so in

1 hour = 70*3=210 bacteria are formed

2 hour = 210*3=630 bacteria are formed

3 hour=630*3=1,890 bacteria are formed

let a  be the number of bacteria at the t=1 hour

if  t= 1 hour then

a=70*3^1=210

if t=2 hour then

a=70*3^2=630

.) the observation by semmelweis that more mothers died of childbed fever when their doctors also worked in the morgue

answer: the exterior temperature of commercial jet planes as they leave the stratosphere and return to the ground increases steadily.

explanation:

the lower most layer of atmosphere is troposphere which extends from 0 to 12 km above the surface of the earth. the temperature initially decreases as distance is increased from the earth's surface. commercial jets fly in lower part of the stratosphere. the stratosphere extends upto 50 km. the temperature in stratosphere starts rising again due to presence of ozone which traps the uv rays.

thus, when the planes leave the stratosphere and return to the ground, the exterior temperature increases steadily.
