edmentum Use the drawing tool(s) to form the correct answers on the provided graph. A researcher 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 was unable to find the answer. good

as given ,→planes t and x are parallel.

→plane t contains line a.

→plane x contains line b.

as we know by definition of line , if we take any two points on a plane the line should completely lie on it i. pass through these two points.

out of the four options given it seems that two possibilities might be true.

1. they may be skew lines , so they will never intersect.

2.if lines a and b are parallel, so again they will not intersect.

other two seems incorrect

because if a and b are perpendicular to the plane ,

1. either they will join each other to form a unique line or2. they will never intersect.

there is no possibility that they will intersect at two points.

approximately 5 hours 32 minutes

let x be the amount of it takes both pumps to fill and 1 pump to empty

so the pumps fill/empty at the rate of per hour

first pump fills at a rate of per hour

second pump fills at a rate of per hour

third pump empties at a rate of per hour

together the reservoir fills at a rate of

+ - =

multiply each term by 720x

120x + 90x - 80x = 720

130x = 720 ( divide both sides by 130 )

x = = 5. hours

(0. × 60 ≈ 32 minutes )

time taken to fill reservoir is 5 hours 32 minutes

i need more information.

what is wise)
