Aresearcher is testing how bacterial cells react to different environments. she placed a petri dish that initially had 32,000 bacterial cells in a vacuum chamber. 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. the researcher creates an equation that models this pattern and can be solved to find the number of cells, y, in the dish x hours after being placed in the vacuum chamber. plot the y-intercept of the equation and the points representing the solutions for the first three hours after the cells were placed in the vacuum chamber. i need to demonstrate it in a graph

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)

(0,32000) (1, 16000) (2,8000) (3,4000)

These are the points on the graph

Hope this helps! :D

Step-by-step explanation:

answer: the answer is one of

step-by-step explanation:   we are given to write a proper fraction where the whole is divided into an even number of equal parts less than ten, and an odd number of those parts exist.

an even number less than 10 may be one of 2, 4, 6 or 8. so, the whole may be one of these four evens.

now, an odd number of these parts must exist, so the numerator must be an odd number, one of 1, 3, 5 or 7. it cannot be 9 because then the fraction will become improper.

thus, our fraction may be one of the following

3 1/3 x 2 3/5 = 8 2/3

step-by-step explanation:

just multiply the first number by the second number to get your answer.
