The cost of a cell phone is $700. according to the cellular device contract, you will need to be $0.22 per minute for first 500. write the function that models the total cost of the cell phone bill for the first 500 min. what is the domain of the function?

can someone answer this question plz

step-by-step explanation:

the answer is 13 cm

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)

mixed number

x+2 -11x+11(over)x^2+4x+3
