A highway had a landslide where 3,000 cubic yards of material fell on the road, requiring 200 dump truck loads to clear away. On another highway a slide left 40,000 cubic yards of material on the road. How many dump truck loads will be needed to clear this slide?

i suppose it should be (y=2x-5)

step-by-step explanation:

the answer is 25 because they're both the same

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)
