Imagine you are cooking dinner for 3 friends the item your cooking is steak, 1 for each friend. you want to prepare the meat as quickly as possible, considering that the side dishes are already prepared and ready to go. each steak requires 10 minutes for it to be cooked the way your friends want it. with 5 minutes being for each side. your big skillet is already in use, and all you have available is a small pan. that can only fit 2 steaks at a time. with some logic you find the fastest way to cook the steaks in you pan in the smallest time possible. how long then, do your friends have to wait until all the steaks are ready?

a: 15 minutes. b: 10 minutes. c: 20 minutes. d: 25 minutes.

c.

step-by-step explanation:

because first you have to add the 4x, 9x, and the 7x together and you get 20x and then you add the last numbers up and you get 5and then you put the subtraction sign in there and that's how you get the answer.

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)
