Answer:
Step-by-step explanation:
Function representing the bacterial growth has been given as,
a). Here 1200 represents the initial number of bacteria taken for the study (1).
b). 1.8 represents the growth factor by which the population of the bacteria is multiplying.
c). Second study is modeled by the function given as,
Here, initial population of bacteria = 1000
Difference in 1200 and 1000 in two studies means → Second study was conducted on 1000 bacteria while in study (1) number of bacteria were 1200.
Answer:
6x2.8
Step-by-step explanation:
i think its 2.8 because 6x3 is 18
6x2 is 12
They give you the equation for Louis, and the table for Carl. Just find out Carl's equation by dividing the money earned by the time. 45 divided by 3 equals 15. Check it by the next time, 75 divided by 5 equals 15. So Carl's equation is y = 15x. 15x ( Carl's) greater than 12x ( Louis's).
Answer:
