the distance-time graph shows information about part of a bicycle journey. use the graph to estimate the speed, in m/s, of the bicycle at the time 6 seconds ​

option: d is correct

step-by-step explanation:

answer-

the equation that models this pattern is

solution-

a researcher placed a petri dish with 32,000 bacterial cells. one hour after being placed in the vacuum chamber, the number of cells in the petri dish had halved. another hour later, the number of cells had again halved.

this can be represented as exponential decreasing function,

where,

putting the values,

y-intercept means, where x=0, so

the coordinate of this poin will be (0, 32000)

this means when x=0 or at the starting of the research, the number of bacteria cells was 32000.

after 3 hours, number of bacteria cells will be,

the   coordinate of this point will be (3, 4000)

in addition, millions of immigrants came to the united states during this era, seeking a better life for themselves and their families. one important result of industrialization and immigration was the growth of cities, a process known as urbanization. commonly, factories were located near urban areas.
