A group of rectangular community gardens is being built on an empty city block the length of each garden will be 90 feet but the width of the garden will vary G stand for the width of the garden think about different ways to find the perimeter of each garden then write an expression to represent each different way

what is the question you are asking?

answer: 89 x 5

step-by-step explanation:

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)
