You are traveling in a car. Your speed is 50 miles per hour. What is your speed in feet per minute?

4399.98 ft per min

Step-by-step explanation:

Divide 50 mi by 60 min = 0.83333Multiply this by 5280 = 4399.9824 ft per min

For this case we have a function of the form:
 
 Where,
 A: initial population
 b: growth rate
 x: time in hours
 y: population after x hours
 We must find the values of A and b, for this we use the following data:
 After 1 hour, the population is 18:
 
 After 2 hours, the population is 27:
 
 We have a system of two equations with two unknowns
 Dividing equations we have:
 
 
 
 Substituting b in equation 1 we have:
 
 Clearing A we have:
 
 So, the function is:
 
 

 A function that best describes the relationship between the time, in hours, and the population of the bacterium is:
 C: EXPONENTIAL

 the y-intercept of the function:
 B: 12

 the rate of change of the function:
 C: MULTIPLY 1.5
